I have installed one of them. But have installed other evacuated tube types ad well. There are other suppliers of evacuated tubes with copper inserts that I believe are better. Old plumber.
Brilliant especially for off grid living. A bit of chain link fence framed across the top would stop larger hail, sit it half metre above it wouldn't give enough shadow to bother its efficiency especially for off grid short not often showers
Just a note that efficiency doesn't matter when the fuel is free. Also, when a home is "going solar" and getting PV as well, it's actually more economical to avoid solar thermal hot water systems altogether and instead add an additional PV panel or two to drive a conventional resistive element in the hot water tank.
Efficiency matters in winter when there is not enough sun. These systems take the load off solar over to allow you more electricity to watch TH-cam but still take a shower so that you don’t stink
Hi Tim. I keep coming back to this video to show everyone how feasible it is to have free, constant, on-tap hot water after initial costs. The reason I'm piping (pun intended) up again is that I've just been to Crete for a holiday weekend and 70-80% of all buildings have similar systems in place. Most of these are panelled rather than tubed, so may not be quite as efficient - but if you're in the Mediterranear, who cares.
Looks cool. I will say the best I have seen is tankless gas waterheaters. I have one with four in my household. My gas bill is 27.00 dollars a month. Very cheap. My family takes very long showers.
6-9 months of the year up there one wants a cooler shower, probably only for washing the dishes do you want hot or super hot water. Was in Townsville many many years ago and they just had a coil of poly on the roof as their primary hot water system, and I guess gas for the cooler month(s).
@@malcolmcheyne3803 This was out past Townsville place called Calcium on the way to Charters Towers. A roll of 19mm or 1inch poly for hot water. Though these days probably will see them for pool heating (though again probably not so much in Townsville/Cairns) but in Atherton in winter gets pretty cool at night and down BrisVegas way houses have them for pools though they occupy a large percentage of the roof to heat a large body of water.
how does this hws compare to the older solar hws systems that have been around for years.? i have one of the older ones, a non-chinese ss edwards which doesnt provide enough hot water in winter. i'm considering putting solar electricity panels in its place which can boil water as well as run equipment to watch youtube videos.
Its not stupid that everything has to be lagged. Get up there on a cold day with cold hands, and you'll quickly find out why it all has to be lagged. The evacuated tube type that I know works on a heat exchange system, no water goes in the tubes and the tank is at mains pressure. The one in this video is gravity fed, and the water is heated directly in the tubes. A bigger tank means a longer tank and more tubes I presume.
What a shame! Your thumbnail says "Off Grid Water!" not HOT water. I was hoping to see a system that would extract water from humidity and fill a tank during the week at our rural property so we could have fresh clean water for the weekend.... Oh well. This is good too. But not what I was looking for.
Good job with the video, so much so that I bought one. BUT, the bee guy did do a good sell on a product that is NOT viable during June/July etc, unless you definitely have the electric elements to go with it. Water goes cold overnight if the air is chilly, warms just enough during the day but the moment you turn the tap on the influx of fresh cold water dramatically reduces the temperature, and is exponential after dark. NOT WORTH THE MONEY! Speaking with the local solar/plumbing guru (post purchase) it is sooo much better to buy an electric water system and additional panels where you set the timing of the system to activate during peak daylight hours. Or just go gas.

Hi Justwait, Andrew here form North Solar. Our clients that have issues contact me to find why there may be an issue with their system. I always help out with a solution, if the system is not suited to them we are happy to give a refund....no questions asked. I don't believe you have contacted us, hence this appears a little bit of a 'Troll' comment'. The most common issues we see iare: - Tempering valve gets blocked on off-grid properties (this is easily fixed by cleaning the mesh), - Installed by a non Registered plumber - Installation under a carport (solar systems don't work well in the shade!) - Tubes being installed the wrong way around I don't know your location, hence can not comment on your situation especially when it comes to the amount of sunlight on your system. Unfortunately we can not control the sun. I always inform my clients that Autumn/Winter may need boosting by either 'Electrical Heating Element' or Wet-back/wet-flue. Please get back to me with a real name so I can assist with a solution. Andrew
@@australianbeesupplies I ignored your little jibes and moved on, but now I have to drop a final review. I don't need to defend myself, I have controlled all of the installation issues from the get-go. It is now that after wasting $5k+ on purchase and installation that in conclusion this thing is being disassembled and is off to the landfill. Late July and for months showering has been nigh on impossible, and heaven forbid if multiple people need to do their ablutions. Washing dishes has been 80% by heating water on the stove because it is usually after 1 household member has showered post sundown and the evening meal prep has been completed. As previously stated, using water after dark exacerbates the issues exponentially. I also stand by the statement that the water is tepid by morning during winter due to what I perceive as poor insulation. Additional points: *The frame is wafer thin and I fear that in a strong wind above 70kph it would collapse if not in a windbreak area. I can't wait to drain this thing and have peace of mind. This is merely my observation and engineering may prove me wrong, but this is a constant worry. Even the frail little rail that holds the base of the tubes is bowed under the weight of only them. *The header tanks containing the float valves leak constantly. Changing between hi-flow to low-flow units makes no difference. Multiple fixes, swap outs and reinstalls sees the problem contained for barely a day or 2. These tanks are pressure fed from a measly 400W pressure pump, you can almost contain the pressure by hand yet these units fail every time. *On the days when the water does reach temperature I become nervous about what this means for summer when the temps are constantly 35+ Celsius? If the leaking float valves aren't bad enough then I fear the daily wastage of water via pressure relief, whereas gas or electric are both regulated - we can't regulate the Australian summer sun! So why would I come back for more? I make no apologies, bee guy, you can defend as you will, my review is based on performance and function. I solemnly stand by my experience that these are not suited for winter conditions in the lower third of Australia WITHOUT electrical or flu-wrapped copper piping from a wood combustion firebox or the like. My plumber/solar guru upon finding out about my purchase just laughed at me prior to install (read my initial input re him). He has a 300 litre Bosch evac-tube system with electrical backup and REGRETS IT - hence his laughing about these rebranded Chinese units. His laughter was justified. I won't jibe you as you did me, bee guy, I will just leave my observations here for the consumer to read about. I am not seeking any refund or the offer of any further solutions, I will wear this cost as a pricey lesson learned, I won't on-sell it to a 3rd party, it is going to landfill and I will return to what could have been 3 - 4 gas units for the cost of this POS. Have a nice day.
Good morning Tim, absolutely brilliant, Cheers

i just posted a comment about this very subject, thank you. i cant watch youtube using the solar hws.

What great timing….just what we’ve been looking for. Thanks Tim
94%! 2 hours plumber time! Heating costs #1 factor in your bills ... ? Not any more. Stunning
Beats the $275 we were promised
Looks cool. I will say the best I have seen is tankless gas waterheaters. I have one with four in my household. My gas bill is 27.00 dollars a month. Very cheap. My family takes very long showers.
Put them on the farm house roof 1997. Great systems.
These look amazing!!! Thanks Tim.
I checked these out many (maybe 20) years ago for North Queensland and was advised they are TOO EFFICIENT for the tropics.
6-9 months of the year up there one wants a cooler shower, probably only for washing the dishes do you want hot or super hot water. Was in Townsville many many years ago and they just had a coil of poly on the roof as their primary hot water system, and I guess gas for the cooler month(s).
Do you see them on any roofs now? I'm surprised they didn't tell you to simply remove some tubes.
@@gregbell2117 Not that I take much notice. No in Townsville.

Great product
how does this hws compare to the older solar hws systems that have been around for years.? i have one of the older ones, a non-chinese ss edwards which doesnt provide enough hot water in winter. i'm considering putting solar electricity panels in its place which can boil water as well as run equipment to watch youtube videos.
Looks great what is the cost all up i am interested

Tim, I'm not sure you should be showing this. those guys are up there without a harness!
Is this the bee guy?!
Yeah…
