Grandad gets us one step closer to having running hot water and Nanny learns just what a Calorifier actually is . A big thankyou to everyone who watches our channel 👍
Thank you Hayley and Ady! I'm really enjoying your Narrowboat build! You're both so innovative and detail oriented, truly a beautiful job! What a day it will be when you launch Wanderlust! Best wishes for continued success and happy cruising!
Ady does such a good job of not only explaining how the system works but also why he's doing it the way he is, which reflects the thought and care that's gone into this build. Your vlogs are really outstanding and the humour from you two, well, that's just a huge bonus. 👍 Steve
@@matthewmaddox8582 That's okay Matthew. My take on this is that if the hot was below the cold, then the rising heat from the hot pipe would make the cold pipe condense and that would drip all over the floor. Less chance of that happening with the hot above the cold. Happy to be corrected if someone knows better.
your a very clever man you defo know your onions when it comes to plumbing all this info will come in handy when I have to figure out how all my heating works good idea about the solar dumping as well put surplus energy to good use keep the great videos coming guys quick update we signed are boat contract and will be starting the build next week I think delivery gone back a bit to 2nd week of Feb but says in the contract if he can do it quicker he will deliver sooner fingers crossed. S C UK.
Thankyou Steve, February will be here in no time. We are hoping our engine can be fitted about then so that will be the finishing touch for us hopefully 👍
Conversation around the office this morning: Colleague : So, are you watching "Squid Game" on Netflix? Me: Nah, I'm watching "Making a Narrowboat with Nanny and Grandad" on TH-cam! This really clever British couple is building a beautiful canal boat 😊 Colleague: Wow, that sounds great! We'll watch that with my young Grandson, he loves to build stuff! Can you send me a link? Me: Sure!!!!
Hello Nanny and Grandad. The build is coming along great since our visit (Claire is still watching cat videos instead of yours though!) I couldn't see a non return valve in the cold water feed. Without this the hot water in your calorifier will blend back into your cold water feed and water tank and so the pressure will drop and the pump regularly cycle. I'm not sure that SureCal supply one with every calorifier but every calorifier needs one! Ours failed a little while back and it took me a while to figure out why our pump kept waking me up in the middle of the night!
@@makinganarrowboatwithnannyandg We are getting close on the builder but boat builders are busy people and don't do communication very well so it is hardwork. Steel prices have also made us a bit hesitant but have now stabilised.... at a very high price. Our shell is now 50% higher in price than when we first started getting quotes!
I just had a quick look on the SureCal website and it appears that they do supply a NRV valve with the 55litre vertical calorifier and it looks like it is part of the cold feed connection/barb so you should be good to go. In fact it looks like there is also one in the cold water feed connection to the blend valve.
@@vonasi2 Yes I thought they did when I read your comment last night but was in bed so checked this morning and yes it is already on there. Comes with the kit. It all didn't go quite to plan and you will see that in next weeks vlog. Its always good though to have all these extra eye's looking out for us.
hahaha he's full of them. Told him he had to keep them clean. It was actually Chicken's lip but Chickens leg is just as weird hahaha. Let me have a guess are you from NZ? If we pronounce leg to the sound of how we pronounce lip we suddenly turn into a Kiwi. Thanks for watching👍
As always well thought out and superb execution. Very satisfying seeing well placed equipment and straight and secured lines very clean work. Loving the journey thanks guys
Thanks Joseph. yes he does love a neat job. He cant sleep if he knows its out of line. What you cant see is all the writing on the pipe is level and facing forward. He would take it all apart if he saw a section with some upside down words lol.
Hello again, your both doing a fabulous job!!! I think you've had words about his tongue 👅 as I've not seen it this week!! 🤣🤣 Really well explained 👏 See you both next week, and the 👅 hopefully!! Take care!!! Xx
Cheers Guys, Yeah the instructions that come with it are straight forward too if you're not sure. You wont need marigolds for this one but keep the Titan handy 🤣🤣🤣 Good luck we will be watching 👀 👍👍👍
@@makinganarrowboatwithnannyandg ours didn't come with instructions but weve managed to download some now though, weve got Beccas dad helping thankfully but you guys made it look so easy, so makes for a great guideline...plus obviously we have the Titan on hand if anything goes dramatically wrong, god luck with your boaty adventure hopefully catch you one day on the cut and we can compare tanks haha 😂😂
Thanks for your calorifier fitting. You have done a good detailed explanation. Ive got to replace my old calorifier because i need a heater element one because i dont want to heat my water by my alde heater no more. I dont know if my calorifier is a single or double coil because its boxed in. Something im going to have to look into more but you made it look so easy to be able to do it yourself to give me confidence replacing my own
Thankyou Paul, The surecal calorifier comes with installation instructions and are easy to follow if you decide to give it a go. Give us a shout if you need any questions answered and think I can help 👍.
Cheers David, No not missed it, We haven't got our sink yet so will wait until we choose what we are going for and then fit the connections when we know exactly where it is going.
For some reason we seldom see the use of collet clips on these JG pipe fittings, red and blue circlips which prevent the fitting from being pulled off easily. They also help ID hot and cold when the system is not running. Dead cheap too.
Another great video. Just one comment though. Personally I wouldn't have varnished the inner side of those ply panels, especially as you've painted the other side it would seal in any damp that might, however unlikely, get in. I think that it's better to treat the Hull side with wood preserver, that would still prevent rot but it allow the timber to breathe. It might be worth you thinking about. Regarding those plastic pipes can't say that I like all those flow restricting right angle bends. They must use up a lot of energy.
Cheers Tony, Ok thats interesting. We were advised at the beginning of our build to seal all our wood both sides and to use Varnish on the reverse to stop damp getting in so thats what we have been doing. What you say makes sense as we have talked about it many times to each other about should we be letting the wood breath a little. Think we will look into a wood preserver for the rest. 👍
Perfect timing Vivien as our Engine has just gone in and is being worked on now. So you will see the Calorifier being linked up to the engine in either this Sundays or the following Sundays episode 👍
Great video thank you! One question regarding your explanation on having stainless steel coils… you mentioned the heat generated from the ‘parking heater’ would be too hot for copper so if one didn’t have a “parking heater” (Webasto/Eberspacher) and used the diesel engine to warm up the stored water, surely the same if not more heat would come from say a Beta marine 43hp engine. The tank is copper, the stainless steel coil meets cold water in the calorifier, the hot water transfer travels through a rubber hose to the cold water not sure stainless steel coils are necessary. What do you think?
Cheers Norman. Some people say modern day pumps don't need an accumulator ( white vessel next to our cold water tank under the bed ) to stop the pump cycling but we fitted one as belt and braces. As for the expansion tank not sure if you mean the header tank high up in the calorifier cupboard or the silver expansion vessel next to the calorifier. If it's the plastic tank at high level I would say definitely. If it's the silver vessel next to the calorifier i would say yes also as it will help to absorb any expansion when the water is heated in the calorifier. I think it recommends an expansion on the hot side of the calorifier in the installation instructions for the calorifier but haven't got them to hand or I would check for you. Hope this helps. 👍
@makinganarrowboatwithnannyandg thanks for reply. Yes i have an accumulator by the cold tank. I also have header tank for central heating, but no expansion tank by calorifier as you fitted, just an expansion pipe which exits out the side of the boat. I am having one fitted but think boat buolder should have fitted it. Assume it wont effect BSC test .
Its a pressure-relief valve. Not temperature, as on unvented domestic cylinders. As water is heated it expands but is not compressible, unlike air. If water boils and turns to steam it expands by 1600 times its volume . Scary stuff. On domestic setups there will be a vertical (open to atmosphere) discharge pipe via a tundish. This allows visual indication of a problem, as well as an escape route. Important to also have an expansion vessel rated at about 10 percent of system capacity. Otherwise you will be constantly discharging hot water and the pump would be continually cycling. Gigger volume is better, The cold side has an accumulator after your pump ..
There is a technical term for your Expansion tank - in Hydraulic terms - it's called an Accumulator. If you're an electrical type - it's similar in principle for a fluid to a capacitor's usage in an electronic circuit. It very much evens out the pulses of the pump, while storing a small amount of pressure charge.
@@makinganarrowboatwithnannyandg Those tanks are used in two ways. One is as an accumulator and you set the air pressure to just below the pump cut out pressure so that it becomes a store of water under pressure that stops the pump instantly cutting in when a tap is opened. The other use is as an expansion vessel where you set the air pressure at just above the pump cut out pressure and it allows the hot water in the calorifier and hot water circuit to expand without increasing water pressure and splitting your calorifier open. Don't ask me how I know! Good to see the build progressing so well.
@@vonasi2 Yes thats right. We have both fitted now. We showed the accumulator being fitted and how it worked when we installed the water tank and pump etc in an earlier vlog and the expansion tank in this vlog. Ady has installed many in his time but its been a real education for me. Looks good too
@@makinganarrowboatwithnannyandg Sorry - I wasn't trying to teach Ady to suck eggs! My comment was meant to be directed at Norm who seemed to be confusing expansion vessels and accumulator vessels as the same thing.
Hi Sam. We got ours from Midland Chandlers in Willington. We picked it up from there as they keep them in stock. I should imagine they would have them on their website too. Hope that helps 👍

Thankyou for your kind words Mitt Man 👍
Another great job just like my Dad taught me only in copper Lol, so much easier these days. Again love this spectacular build. Cheers, Nigel
Cheers mate.You're right. So much easier these days using plastic pipe but do love a bit of copper.
Been watching lots of your videos which have been helping me sort my boat out! Thank you for the great videos

Okay, I've got to ask for my own education....why is it desirable to run the hot pipes above the cold...avoid heating up the cold water? Regards, Matt
Ignore my last message...typed in the wrong space...must put my glasses on when doing this ;-)
@@matthewmaddox8582 That's okay Matthew.
