I’ve had a lazy spa Miami for over a year. I use it every morning 365 days a year whatever the weather. I’m in it for about 30mins for exercising.we switch it off completely after use then switch it back on again before we go to bed about 11pm - it heats up to 38 degrees. We put 3 or 4 spa mini cleansing tablets in the dispenser every morning after use and clean the filter daily. Our water is crystal clear and we never bother with any other chemicals. We love our spa.
Good video. My only argument with turning it off would be you have to turn it on 15 hours before you want to use it. For me having a tub allows me to use when I want to use -irrespective of time and not waiting for it to heat up. Each to their own though
If you turn a hot tub off there is no water circulation or filtration. You can’t just throw in sanitizer in a tub with no flow and expect the water to be safe as well, you can’t just add chlorine when you feel like it. To keep it sanitized you have to put sanitizer in everyday to every other day and shock at least every other week if you have an ozonator. Once a week if not. Not to mention, unless you live in a warm climate you CANNOT turn off the t7b during cold weather.
Yep, agreed. We used to turn it on and off every day and got a huge electricity bill. By leaving it on at a lower temperature we still have a big bill, but its not as bad as before!!! ;-)
I've enclosed my hot spa in a gazebo. During the winter I cover the gazebo with military canvas stormsheets. The floor is insulated with 1 layer rubber matting purchased from B&Q for £10. The next step is a wrap foil insulation around the sides and definitely the top.
Wow! This is a brilliant and incredibly well detailed and easy to understand video. I am lucky enough to own both a hot tub and an endless pool (10 ft x 20 ft) which has a motor to generate a current so that I can swim against it daily. (After swimming each day, I get in the hot tub.) It has been a learning curve to monitor my electricity bills and try to figure out how to adjust temperatures for daily usage. Having solar makes a huge difference in the warmer months especially. Your video is by far the best I've seen. It has taken me about a year of calculating and experimenting to be at a point where I could follow your explanations effortlessly and still benefit greatly because the information just "crystallized" for me. I am enlightened. Thank you!
Very good advice Adam! We bought a Lay-Z-Spa about 8 weeks ago and had the same dilemma given the ridiculous electricity prices currently. Thankfully, also owning an electric car, we have a special tariff with Octopus which gives us electric at 5p per KWh between 12:30 and 4:30 so I have it come on at the same time as the car for that 4 hour period for the two nights prior to us using it. Yes it drops a couple of degrees during the day before use but it saves us a fortune in electric
REALLY appreciate your analysis. ONE NOTE though: using DIY foil insulation you suggest in the "insulation" section (starting about minute 2) - that insulation (looks exactly like what is universally sold in hardware stores) is utter crap if exposed to much sun (as in the total tub cover shown - probably fine under tub out of the light). It degrades amazingly quickly. I used some to insulate under and next to a rooftop barrel I was using for solar heating of pumped hot tub water (pretty effective way to heat up tub water during sunny months - about April into October in CA, USA). After just a year exposed to lots of sun (but only tangentially) and the aluminum foil (Mylar probably) degraded to flakes and blew away in the wind! A real mess and after about a year utterly useless or, since it cost money and time to use it, worse than worthless. I don't think it saved much energy at all anyway.
I have insulated mine all the way around and thd top also. Instead of buying one of those inflatable lids that cost a fortune I bought an inflatable round lilo for £10 off ebay. Does exactly the same and on my 3rd summer now and no holes whatsoever. I also turn mine off after use as can't predict the British weather and if I think I'm going to go in it the next day just turn it on around 7pm it's great up to 38 by 10am
An instantaneous/ tankless propane heater with a submersible pump could be a good addition that would pay for itself in energy savings. It would provide a cheap and quick reheat. The tub could then be kept at lower temperatures and reheated for use each time.
I have mine set to heat up between 12 midnight and 5am as this is the cheap rate on my EV tariff (EDF or Octopus) quick workout then dip in the hot tub, starts the day great!
There should be a calculator for the thermodynamics where you could input stats like how often you use it, temp set, outside temperature etc... And it would tell you best method for efficiency
I use mine 2 weekends a month Fri, Sat, Sun then empty it, It takes approx 1 hour to refill with tub with fresh, clean hot water from my garden hose connected to Hot Water tap in my kitchen. 1hr of Gas is FAR cheaper than any Electric option, and it never has water older than 3 days too....
I use a coupe of those heavy moving blankets atop the air lid for my Intex 4-person hot tub. About 4-5 kwH per day less power consumption. 104F, 24/7 operation, about 7 kWh power use over 24 hours.
i significantly save money on energy by keeping my hot tub in a round portable greenhouse. the round ones allow more solar heat in keeping the air temp nice and steamy all year. benifit i get a sauna and hot tub from one unit. i am in michigan USA and the air temp in winter averages around 20degrees Feherinhiet but inside the greenhouse (i call it my bubble) the air stays 60 degrees all winter. its very nice to enjoy on cold nights
Seems like good advice except the part when you said don't use it in winter. Perhaps look at Scandinavian countries where hot tubs are used all year round and more so in winter, for more tips on insulation and heating.
I use my new lay z spa in winter as it has freeze shield. It’s used every other day so I keep it at 36 degrees then push up to 39 a few hours before going in it.
Great videos Adam. Thanks. I use my hot tub every night at the moment. In this cold weather I can save lots of electricity by not using the bubble feature for long periods of time. It uses ambient cold air and cools the hot tub very quickly. Additionally rather than leave the tub heater set to 40 degrees all the time I leave it set to whatever temperature the water is when I finish my soak, normally somewhere around 36 degrees. It's not worth re-heating it immediately because it will then have to maintain this higher temperature for about 23 hours until I next jump in. It's going to have to do that re-heat anyway so I just turn it up a couple of hours before I jump in again the following day. Occasionally I have topped the tub up from a hose pipe connected to a hot tap in my house for quick reheat or to extend a session in the evening with the bubbles on. Our domestic hot water from the boiler is much cheaper. Luxury. (Every time I re-fill the tub I start off with domestic hot water too.)
My recommendation if used once or twice a week is get a connector and fill with hot water from the mains. Instant hot water and very little electricity used
I am currently filling our tub for the first time this year. We are low / intermittent (use every few weeks) users and used to leave it on permanently during our "April to October' season. We decided to start late this year and I will now turn OFF between sessions. Really useful info - Thanks Adam. This years 'winterisation' included using a home made cover - made from a plastic damp proof course sheet. It kept a lot of water and dirt out and I will definitely be using it during periods of inactivity and over next winter. My next places to explore are solar panels to warm water, combined with a small 12 volt PV panel and pump to reduce water heating costs.
Great video mate. My strategy has been to turn the hot tub off overnight in which time it cools to around 28C and then turn it back on early in the morning and it’s usually back up to around 36/37 by lunchtime. Obviously these temps and times are weather dependant. We use the tub multiple times per day so it sounds like from what you’re saying I would be better to keep it on overnight and not let the temp drop so much. Maybe set it to around 33/34 and only have to heat it a few degrees again in the morning. I don’t have any insulation under or around it but it is fairly sheltered where it is situated. However my next step should definitely be to use some foil insulation underneath.
Looking at using foil backed foam sleeping camping roll Mats X 3 to insulate sides of 1.8m diameter inflated hot tub... Question is ... Would you put foil inside or out ... So would be foam side be against the tub wall or should it be foil side? n why?
This is good advice, and I’m very glad I found this great video. As someone who travels about every week, I’ll be turning mine off completely on the evenings before I fly.
Good video and information, the only additional consideration here is maybe the impact on water quality and chemical considerations during all these scenarios. Most hot tubs have circulated water function (without heat) which will help keep the water moving a little but it’s the temperature changes that I’m more concerned about.
This was so handy and a great insight into hot tub economy, I'm putting mine in a well ventilated conservatory so hoping for no big drops in temperature and all year round use. Thanks again.
Sound advice however if you factor in the extra wear and tear hours running the cheap Chinese pump and overinflated cost of replacement units, better to turn it off as much as possible. This will easily offset most of the logical savings you raise.
Good video but im on debatable as iv been told its better too run the circulation filter full time even when the heater is off so the water is crystal clear with the appropriate chemicals put in . I put in 3 tablets in every 3-4 days and had to say i even went 9months before water change and didnt really need it but did it all the same anyway and its been 5 years now plus and the heater has just packed in ,was going to get it fixed but was again told weve done well and thats the overall time limit for these so just brought a new heater and came here to remember how to install it again
Perfect! Thank you very much for all the technically - very important! In the U.S. we have the lowest cost per kw between midnight and 5 am - if we choose the perk plan. We charge our Tesla that way too. :) Your videos are very clear, straight to the point = valuable. Cheers!
Got mine on amazon, (£7 GBP) it attaches to almost any tap inc mixers & allows a standard garden hose to be used right from the kitchen.. this way you can use the DHW system & fill the tub with hot water rather than heating for circa 15hrs
All your hot tub videos are so helpful and full of excellent advice. I am receiving my lay z spa Hawaii this week and I have done lots of research using all your videos. Thank you very much, Jim
Have a spare hotwater feed from washing machine just run pipe to hottube set boiler to 40 oc and fill so the combi boiler heats water at first fill then just remove half water then refill
@@SailingAquila most new washing machines only use cold feed so there's a hot feed just doing nothing get washing machine hose cut off one end connect the other to washer tape hot then put hole in wall then buy outside garden tap and connect the cut end to that 😀😀😀
This has been very helpful. I have eco 7 electric. So I will try to use heater during the night. I use once a day (sat, sun, mom &/tues) So will maintain a 35 degree heat. I then have a 3 day gap (we’d, thurs and fri) each week when not in use. So will turn off completely after use Tuesday , turning back on Friday night ready for sat use. (I hope I got that all correct !)
Top man and there was me keeping it on all the time lol when I only use it just 1 a week now and turn heater off and keep filter on I turn the heater on at 9pm at night and by eary afternoon its ready for me to get in
No mention of having to keep the water filtering and being mixed with the chlorine, there's a lot of water and it takes time for it to circulate, the initial tips about insulation and best energy provider are sound but you could cause all sorts of trouble having unsafe water and to random chemical concentration. Keep it running, keep checking your chemicals.
You risk build up bacteria in the pipes, and spitting out sludge when you do fire it up again, meaning you'd be spending more money on refilling, cleaning and reheating the water
As long as the water has sufficient chlorine levels, it should be fine in the pump for some time - at least days, and possibly weeks, at a time. I'd still recommend testing the chlorine level in the water a couple of times a week anyway, and you'll need to run the pump to mix the water for this.
So far I have only insulated the bottom, the day we picked it up I spent $150CDN on 2” thick foam R10 insulation and a roll of reflective insulation to go on top of the foam, probably overkill but wanted the bottom insulated the most. Still considering wrapping the outside with reflective insulation as well. I keep it at 96 deg F/35.5 deg C during the week when I am gone and my fiancé uses it occasionally, the days she knows she wants to use it I use my phone app and turn it all the way up to 104F/40C about 5hrs before she needs it then turn down again once she’s out. Would love to have a power meter that keeps a total usage stored connected to the plug just to see what is working best.
The radiative power is proportional to T to the fourth power. The more you turn it off the less you pay regardless of how soon you will turn it on again.
Had my hot tub a couple of weeks, electric bill shot up by £20 a week! Eeeek. I will follow your suggestions Adam and hope I can lower the running cost. Thank you from sunny Plymouth!
If you turn off the heat and filter, what do you do about testing the water and maintaining chemicals? Or do you not have to do the daily chlorine dose and then just shock dose it a few hours before you want to use it?
Another great video Adam. Just fired ours up this week for new season and first night forgot to switch it off, so began to wonder if I was wasting energy, this video helped me think thro the strategy I need. Also having solar panels the recent sunny weather has been a bonus. I bought the Lay-Z-Spa ground insulation panels so hopefully that helps. Thanks again, Hugh
Good ideas for saving energy, however trying to keep your water chemistry under control requires your hot tub to be at bathing temperature. By having it increasing and decreasing constantly makes for a difficult time in correcting any issues with chemicals.
Thanks for this. Really helpful! In summer I use it quite regularly, in winter not as much - that being said, I want to make sure that the water stays filtered and clean so would like to run the pump on its own. Do you have recommendations for frequency and length of time to run the pump without the heat to keep the chlorine up and the water clear please? Thank you
this is my concern. My hot tub person on our vacation rental says to keep it on 24/7 for our guests to keep it cycling the pumps and filtering and clean.
When the filtration isn't on for the time it's off inbetween uses Say few days will water still be OK to.use . Are the tablets enough to keep water safe and fresh 🤔 I'm worried it may be green x
Personally I find people who have the most problems are people who constantly fuss with things. Have had hot tubs in my yard for around 30 years with almost no issues at all. I set the controls and forget about it. Only turn it off when doing maintenance or repairs, or possibly cut the temp down if going on holiday. Cost to run? (electricity) Just over $1 per day in USA money, average over a year.
Thanks for much for your hot tub videos! We have just got a Bali and I had absolutely no clue on how to setup and whether to turn off or keep on! Subscribed! 👍🏻
That was well spoken n easy to understand, thank you, I'm struggling with the chemicals, also when I used de scaler I noticed a rusty colour in the water only a bit but it was greesy any ideas please?
Have just got a Miami and worried about electricity charges. Really helpful video explaining options but tub is used once a day at about 1400hrs so with cheap night electricity would it be possible/sensible to run it at 40 from 2200 to 0700 and then off until being used. After use leave it off until that evening and again turn it back on at 2200. What’s the flaw!
Hi just wondering if you ever figured this out. We got a hot tub at the wkend and an outside hot tap. Trying hard to be economical for a change. Any advice would be appreciated. Thanks
Hi Adam Thanks for your informational videos, I have found them to be useful. Can you possibly advise with the below. How long should the pump be left on for dependant upon use? Thanks again Kev
You don't really need to leave the pump on except for when heating. Some people like to leave it on for a couple of hours after using to give it a chance to clear out any debris, but it's not essential.
Has anyone bought a jackery solar powered battery to use with your hot tub so it keeps the cost down. I'm not sure if they would be strong enough power to use with the hot tub machine..
Hi Adam, have liked and subscribed.......and on this video made notes. One question I can't seem to find the answer to. Now the answer may seem obvious but I'd like to hear it confirmed........Once the heater has got everything up to your chosen temperature (e.g 38 degrees), the red heating light turns green to confirm that. Does this now mean that it is no longer using 2KWH of electricity? I ask because, other than the change from red to green, the pump unit still appears to be on and humming in the same way? From experience I expect to hear some thermal cut-off solenoid click (but I don't) - much thanks in advance.
Great video , wouldn’t the water go bad if you turn it off for 3 days at a time ? I thought it had to be moving and at a certain temperature to stop bacteria growing, also this depends on time of year I’m guessing as can’t turn it off when it’s cold in case it ices up and can crack the plastic or pipes? X
What about the filter???? Aside from the heater it needs to filter the water for at least 8 hours a day so how do you do this with a lazy spa??? Thanks
It's a good idea to leave on for a few hours or overnight after use, but don't feel it's necessary to use it for 8 hours every day if you've not been using the tub. As long as your chlorine levels are ok, you can leave it without constantly filtering the water.
Hi, Thanks for creating these videos - everything Ive learnt about my laz y spa Ive learnt from you! I just wondered whether you have any advice for using the timer when it comes to heating? Im confused as to what the time means - if I set it for 3 hours does that mean it will start heating in 3 hours or will it heat for 3 hours from the time I set it?? Thanks
Hi Katie. I'm trying to get my head around it as well - would appreciate a video! If you've also got a Lay-z-spa I _think_ that (after hitting the timer button) the first number you give it is how long you want it to heat for and (second push) the next number is the delay, so, in how many hours you want the heating to start. However I think it didn't work for me because I already had the heater element on so it just ignored it completely. I think you might need to start the timer with the heater off. I'll give it another go tonight...
Hi Adam, great videos which I used to set up our Maldives Hydrojet Pro and keep it running spot. We really need some advice on running costs and cost savings. We use our hot tub at least 3-4 times a week on an evening and have tried different timings to get the hot tub up to 40 degrees ready for when we use it on an evening. Steadily our electricity bill has shot up, we expected an increase but it's costing us about £100-£130 a month!!!! Our hot tub is boxed in with a timber surround to keep it out the wind, we're using a bubble wrap thermal blanket under our inflatable lid and we even have the pump unit insulated. We leave our hot off over night and with all the above the temp only drops to around 32 ish degrees. Having left the filter running all the time we then turn the heater on around 8am knowing that by 7pm ish it's at full temp and ready to use Can you give any advice as our costs are getting ridiculously expensive. Thanks, Mike.
Sounds like you're doing most things right and the cost is unavoidable. You could try turning it fully off overnight. It'll get to run for a few hours anyway during the daytime when reheating so plenty of time for the filter to get to work. The last resort would be to consider getting solar panels. They're a good investment anyway if you're planning on staying in the same house for the foreseeable future.
@@SailingAquila Thanks for the reply Adam, we've already got solar panels installed but at this time of year they don't produce a great deal. I'll try turning it off altogether at night. I actually didn't realise that was an option and thought the filter had to be running all the time as part of the cleaning process. Thanks, Mike.
I mean turn off completely including the filter. It's a good idea to let the pump run for a few hours or overnight to help remove any bits, then clean the filter and check the chemicals. As long as you monitor the water occasionally, you can leave it turned off for days or even a week or two without any problems.

I put mine in my basement on top of exercise mats for insulation and cushion.
we just bought the Lazy Spa Milan, thanks for the vid Adam really useful info - you have a new sub !
Sound advice however if you factor in the extra wear and tear hours running the cheap Chinese pump and overinflated cost of replacement units, better to turn it off as much as possible. This will easily offset most of the logical savings you raise.
Good video but im on debatable as iv been told its better too run the circulation filter full time even when the heater is off so the water is crystal clear with the appropriate chemicals put in . I put in 3 tablets in every 3-4 days and had to say i even went 9months before water change and didnt really need it but did it all the same anyway and its been 5 years now plus and the heater has just packed in ,was going to get it fixed but was again told weve done well and thats the overall time limit for these so just brought a new heater and came here to remember how to install it again
Perfect! Thank you very much for all the technically - very important! In the U.S. we have the lowest cost per kw between midnight and 5 am - if we choose the perk plan. We charge our Tesla that way too. :) Your videos are very clear, straight to the point = valuable. Cheers!
You have very good information here, also most people do not use their spa 2 times a day.
It is also cheaper to fill your hub initially from your domestic hot water supply. You will need an hose adapter for your kitchen mixer tap.
Got mine on amazon, (£7 GBP) it attaches to almost any tap inc mixers & allows a standard garden hose to be used right from the kitchen.. this way you can use the DHW system & fill the tub with hot water rather than heating for circa 15hrs
All your hot tub videos are so helpful and full of excellent advice. I am receiving my lay z spa Hawaii this week and I have done lots of research using all your videos. Thank you very much, Jim
I used to pump mine into combi boiler into the cold feed and back out through hot water tap not tried in my new boiler
Great video. And today it is more relevant than ever.
Another spot on video Adam. Keep these up, you deserve a lot more subs.
Have a spare hotwater feed from washing machine just run pipe to hottube set boiler to 40 oc and fill so the combi boiler heats water at first fill then just remove half water then refill
That's a helpful tip, especially on the first fill as you can add chemicals immediately rather than having to heat up to 20 degrees.
@@SailingAquila most new washing machines only use cold feed so there's a hot feed just doing nothing get washing machine hose cut off one end connect the other to washer tape hot then put hole in wall then buy outside garden tap and connect the cut end to that 😀😀😀
Takes 45 mins to fill a 1.22p in gas
This has been very helpful.
I have eco 7 electric. So I will try to use heater during the night. I use once a day (sat, sun, mom &/tues) So will maintain a 35 degree heat. I then have a 3 day gap (we’d, thurs and fri) each week when not in use. So will turn off completely after use Tuesday , turning back on Friday night ready for sat use. (I hope I got that all correct !)
Top man and there was me keeping it on all the time lol when I only use it just 1 a week now and turn heater off and keep filter on I turn the heater on at 9pm at night and by eary afternoon its ready for me to get in
No mention of having to keep the water filtering and being mixed with the chlorine, there's a lot of water and it takes time for it to circulate, the initial tips about insulation and best energy provider are sound but you could cause all sorts of trouble having unsafe water and to random chemical concentration. Keep it running, keep checking your chemicals.
You risk build up bacteria in the pipes, and spitting out sludge when you do fire it up again, meaning you'd be spending more money on refilling, cleaning and reheating the water
When the pump is off the water can become stagnant. I’m not sure if completely off is a good idea. It may just turn you off from ever using it.
As long as the water has sufficient chlorine levels, it should be fine in the pump for some time - at least days, and possibly weeks, at a time.
I'd still recommend testing the chlorine level in the water a couple of times a week anyway, and you'll need to run the pump to mix the water for this.
So far I have only insulated the bottom, the day we picked it up I spent $150CDN on 2” thick foam R10 insulation and a roll of reflective insulation to go on top of the foam, probably overkill but wanted the bottom insulated the most. Still considering wrapping the outside with reflective insulation as well. I keep it at 96 deg F/35.5 deg C during the week when I am gone and my fiancé uses it occasionally, the days she knows she wants to use it I use my phone app and turn it all the way up to 104F/40C about 5hrs before she needs it then turn down again once she’s out. Would love to have a power meter that keeps a total usage stored connected to the plug just to see what is working best.
The radiative power is proportional to T to the fourth power. The more you turn it off the less you pay regardless of how soon you will turn it on again.
Had my hot tub a couple of weeks, electric bill shot up by £20 a week! Eeeek. I will follow your suggestions Adam and hope I can lower the running cost. Thank you from sunny Plymouth!
Did it help?
If you turn off the heat and filter, what do you do about testing the water and maintaining chemicals? Or do you not have to do the daily chlorine dose and then just shock dose it a few hours before you want to use it?
If there was a way to save money on gas and electricity, would you want to know about it?
Another great video Adam. Just fired ours up this week for new season and first night forgot to switch it off, so began to wonder if I was wasting energy, this video helped me think thro the strategy I need. Also having solar panels the recent sunny weather has been a bonus. I bought the Lay-Z-Spa ground insulation panels so hopefully that helps. Thanks again, Hugh
When you turn off the spa, wouldn't that make your water quality go down since there is no circulation going on?
Good ideas for saving energy, however trying to keep your water chemistry under control requires your hot tub to be at bathing temperature. By having it increasing and decreasing constantly makes for a difficult time in correcting any issues with chemicals.
Thanks for this. Really helpful! In summer I use it quite regularly, in winter not as much - that being said, I want to make sure that the water stays filtered and clean so would like to run the pump on its own. Do you have recommendations for frequency and length of time to run the pump without the heat to keep the chlorine up and the water clear please? Thank you
this is my concern. My hot tub person on our vacation rental says to keep it on 24/7 for our guests to keep it cycling the pumps and filtering and clean.
Thanks Adam, this video really helped me to adjust the temp to what will suit best for me & my family!
When the filtration isn't on for the time it's off inbetween uses Say few days will water still be OK to.use . Are the tablets enough to keep water safe and fresh 🤔 I'm worried it may be green x
Great Video Adam. Useful to know and well put together! Keep them coming.
Personally I find people who have the most problems are people who constantly fuss with things. Have had hot tubs in my yard for around 30 years with almost no issues at all. I set the controls and forget about it. Only turn it off when doing maintenance or repairs, or possibly cut the temp down if going on holiday. Cost to run? (electricity) Just over $1 per day in USA money, average over a year.
In Europe, especially the Netherlands, we've very high energy bill costs since the R-U war...
Brilliant thank you just ordered one won’t get for another 2 months so will be watching this again 👌
My solar panels are hot water only, so I just fill the hot tub with already hot water. Job done. Then the hot tub is just keeping it warm.
how did you do this
Thanks for much for your hot tub videos! We have just got a Bali and I had absolutely no clue on how to setup and whether to turn off or keep on! Subscribed! 👍🏻
Lovely Plymouth. How strange, small world 👍🏼
Say for example I set my temperature for 25* do I keep the heater button on or turn it off and it will kick in itself to maintain the 25*
Great video. Can you please advice if the filter is to stay on if you turn off the heat ? Many thanks. Kelly.
very useful video. I am still confused about the "rest" and "ready" function.
That was well spoken n easy to understand, thank you, I'm struggling with the chemicals, also when I used de scaler I noticed a rusty colour in the water only a bit but it was greesy any ideas please?
Exactly what type of insulation is to be around around the spa?
Thanks for the videos u put out, moving to house with hot tub.
Have just got a Miami and worried about electricity charges. Really helpful video explaining options but tub is used once a day at about 1400hrs so with cheap night electricity would it be possible/sensible to run it at 40 from 2200 to 0700 and then off until being used. After use leave it off until that evening and again turn it back on at 2200. What’s the flaw!
I often empty half the water and fill it with hot water from the tap to get it to 40. Am I saving money as I’m not using the hot tub heater only gas?
I was thinking of doing the exact same thing, it would be like running a bath then really or maybe 2!
Hi just wondering if you ever figured this out. We got a hot tub at the wkend and an outside hot tap. Trying hard to be economical for a change. Any advice would be appreciated. Thanks
We use it every other day.
Always good videos
Hi Adam
Thanks for your informational videos, I have found them to be useful.
Can you possibly advise with the below.
How long should the pump be left on for dependant upon use?
Thanks again
Kev
You don't really need to leave the pump on except for when heating. Some people like to leave it on for a couple of hours after using to give it a chance to clear out any debris, but it's not essential.
Brilliant information, thank you very much for such well descriptions, step by step I will use your recommendations
Should I leave the filter running when I have turned off the heating to keep it clean?
You can leave it running for a few hours or overnight to clean it after use, then it's fine to turn off completely.
@@SailingAquila thank you.
Very helpful information. Thank you
Well described. I’m buying a hot tub. Thank you for you explanation.
Has anyone bought a jackery solar powered battery to use with your hot tub so it keeps the cost down. I'm not sure if they would be strong enough power to use with the hot tub machine..
thanks so much, this has answered lots of questions I've had!
15hours for a hot tub to warm up ,doesn't that depend on the size of the hot tub? Since we have variety of the sizes.
A really informative and easy-to-follow explanation. Thanks, Adam, you have a new subscriber!
Same here. I bought one from Blue Whale Spa and grappling to understand the mechanics of it. The video was very helpful. 👍🏾👌🏾🙏🏾
Hi Adam, have liked and subscribed.......and on this video made notes. One question I can't seem to find the answer to. Now the answer may seem obvious but I'd like to hear it confirmed........Once the heater has got everything up to your chosen temperature (e.g 38 degrees), the red heating light turns green to confirm that. Does this now mean that it is no longer using 2KWH of electricity? I ask because, other than the change from red to green, the pump unit still appears to be on and humming in the same way? From experience I expect to hear some thermal cut-off solenoid click (but I don't) - much thanks in advance.
is there a way to automatically shitboff the hot tub during the day hours?
Brilliant advice thank you watch it before I got my tub and recap now when I’ve got it thank you so much 🙏🙏x
Great video , wouldn’t the water go bad if you turn it off for 3 days at a time ? I thought it had to be moving and at a certain temperature to stop bacteria growing, also this depends on time of year I’m guessing as can’t turn it off when it’s cold in case it ices up and can crack the plastic or pipes? X
What about the filter???? Aside from the heater it needs to filter the water for at least 8 hours a day so how do you do this with a lazy spa??? Thanks
It's a good idea to leave on for a few hours or overnight after use, but don't feel it's necessary to use it for 8 hours every day if you've not been using the tub. As long as your chlorine levels are ok, you can leave it without constantly filtering the water.
Hey Adam. Can you run the hydros and air bubbles at same time. I know you can’t run hydros and heat together. Thanks
Hydro use during the day here in Canada is at peak rates.
Clear and well reasoned. Thanks Adam
Nicely done, cheers
Hi, Thanks for creating these videos - everything Ive learnt about my laz y spa Ive learnt from you! I just wondered whether you have any advice for using the timer when it comes to heating? Im confused as to what the time means - if I set it for 3 hours does that mean it will start heating in 3 hours or will it heat for 3 hours from the time I set it?? Thanks
Hi Katie. I'm trying to get my head around it as well - would appreciate a video! If you've also got a Lay-z-spa I _think_ that (after hitting the timer button) the first number you give it is how long you want it to heat for and (second push) the next number is the delay, so, in how many hours you want the heating to start. However I think it didn't work for me because I already had the heater element on so it just ignored it completely. I think you might need to start the timer with the heater off. I'll give it another go tonight...
BUT it takes a looonnnggg time to heat up unless you have a 12-13kw gas heater
Filter runs at 0.05kw so £7.20 a month for lay z spa. Just leave it to run !
Hi thx for that. If i switch the tub off do i always keep the filter on? Pls
Always keep filter on Fiona
Given me lots to think about... Cheers mate great video 👍
Merci beaucoup Adam des bons conseils que je vais adopter.
Hi Adam, great videos which I used to set up our Maldives Hydrojet Pro and keep it running spot. We really need some advice on running costs and cost savings. We use our hot tub at least 3-4 times a week on an evening and have tried different timings to get the hot tub up to 40 degrees ready for when we use it on an evening. Steadily our electricity bill has shot up, we expected an increase but it's costing us about £100-£130 a month!!!! Our hot tub is boxed in with a timber surround to keep it out the wind, we're using a bubble wrap thermal blanket under our inflatable lid and we even have the pump unit insulated. We leave our hot off over night and with all the above the temp only drops to around 32 ish degrees. Having left the filter running all the time we then turn the heater on around 8am knowing that by 7pm ish it's at full temp and ready to use Can you give any advice as our costs are getting ridiculously expensive. Thanks, Mike.
Sounds like you're doing most things right and the cost is unavoidable.
You could try turning it fully off overnight. It'll get to run for a few hours anyway during the daytime when reheating so plenty of time for the filter to get to work.
The last resort would be to consider getting solar panels. They're a good investment anyway if you're planning on staying in the same house for the foreseeable future.
@@SailingAquila Thanks for the reply Adam, we've already got solar panels installed but at this time of year they don't produce a great deal. I'll try turning it off altogether at night. I actually didn't realise that was an option and thought the filter had to be running all the time as part of the cleaning process. Thanks, Mike.
Does 'turn off' mean just the heat, or everything else aswell (the pump/filter too)?
I mean turn off completely including the filter.
It's a good idea to let the pump run for a few hours or overnight to help remove any bits, then clean the filter and check the chemicals. As long as you monitor the water occasionally, you can leave it turned off for days or even a week or two without any problems.
@@SailingAquila Thanks for all the tips Adam - we're new to this!
Amazing video really informative and helpful thank you for the advice
