- Mee name's Allen Hart and in today's video we're gonna be installing underfloor heating in my garage. We've got Dave here from Pro-Warm. Dave's gonna tell us a little bit about the underfloor heating and then we've got Kieran and Kieran's gonna help us install the underfloor heating as well. But he's gonna be doing most of the work and I’ll be having a watch. (laughs) - Dave, can you tell us a little bit about what we've got here? - Yeah, so we're basically installing a high output in-screed wet system. Just as a quick overview, we've got our manifold, which is what we're gonna connect all our pipework to, and staple the pipework down.
And the other bits and bobs we'll talk more about as we're getting in with the install. - And Kieran, what are you gonna be doing on this? - All of the work, apparently. (laughs) Everyone's just gonna watch me.
So we've removed the manual vent valves that come fitted to the manifold as standard.
And we've replaced the top one with an automatic air vent just to reduce the likelihood of air locks and just make the system easier to maintain in that regard. And on the bottom one, we've taken,
obviously taken the vent valve out and replaced it with a pressure gauge so that we can see what pressure the system is at, at any given point in time. And we can do so without hooking up any external tools or equipment to the manifold. We just, at a glance, can look at this gauge and see and make sure that the system is retaining the correct pressure. And once we've filled it up and pressurised it ready for the screeders,
we can make sure that it's holding pressure before we leave without hooking anything up.
So Kieran’s installed the manifold on the wall now. What's next? What's Kieran doing now? - Yeah, so the next thing for us to do is to start putting this stuff down. So this is called a laminon. It's a grid membrane and it's also a vapor barrier. So basically it just adds to the sort of damp roofing, like a visqueen of like that type of material would. And each one of these little squares is 50 mil. So as we're spacing it at 150, we're just gonna go three squares along with the pipe work and it'll make our life a lot easier.
So this stops the liquid screed, damaging the insulation? - Yeah. You see we've got that slight upturn against the wall. So that's just gonna make sure that no screed can get behind and start lifting the insulation boards up.
So Kieran, you put the membrane down now. What's next? - So basically now we need to install this edging insulation. So the purpose of this is to stop your heat going into your walls, basically you're losing heat through the external walls.
So yeah, this will just go all around the perimeter, around the edge of the walls. - Yeah. - Yeah, and basically just put that in for that. - And that also allows a little bit of expansion. - Yeah, expansion for your concrete as well. - Yeah, and what I noticed on this as well, it's got like a sticky backing, right? - Yeah. - So that makes it a lot easier. - It does. - To stick on. - A lot easier, yeah. So basically it's got a backing on it here. So once we put that in, this basically just sticks straight to the wall. So it's very easy to install as well.
So you're just finishing off this first loop now with this underfloor heating. Could you tell us a little bit about this underfloor heating and why are you suggesting that I should have this for my house? - First of all, obviously the manifold's got four circuits on it. - Yeah. - So there's a maximum amount of pipe that you can put on one run. So that's a hundred meters. Otherwise, if you run the pipe for too long, what happens is you get too much of a differential between the flow and the return. - Right, okay. - And then, you know, the first part of the circuit's nice and warm, and then the end part, it's giving up all of its heat and there's nothing left. So we've gone with four circuits to make sure we've got a nice, even heat distribution across the whole floor and consistent heating for the whole entire space. That's sort of point of note number one. - And what is the system? What's it called?
- This is just what we call an in-screed staple system. So where you're gonna have the new screed put down in a couple of days, the pipe sits within the screed, and we're just stapling it down onto the insulation just so that it doesn't move or come to the top or just to hold it nice and secure for the screed to go over the top. - Why have you gone with this over a different type of system? - So we've got two other methods available. We've got a clip rail, which is like a long strip. If you imagine like a carpet gripper for pipe, we've got that kind of system, and then we've also got what we call an egg crate or a castellated system panel where you just sort of lay it down and it sort of clips in.
Hi Alan I have a Worcester 35CDi greenstar 47 311 94 when the hot water tap is turned on it goes straight to lock or over heating it only does this on the hot water circuit it’s had a new hot water heater exchanger the diverter valve opens on hot water it’s had a new main board the boiler is fine if the pump is wired constantly running all the time does the pump work for hot water or just heating if it’s put back to factory settings and I turn on the hot water tap it climbs to a hundred degrees in a few seconds loads of engineers have been around just throwing parts at it with no fix
Have you Called WB to see if you can get a fixed price repair?
How much you changed since you did that cold water snatch 8 years ago , remember me telling you that you could be a teacher ?
I could never be a teacher, Not smart enough but thank you so much for your many years of support.
Great Video, Im just about to install a Cemfloor liquid screed 60mm thick with 16mm underfloor heating pipework and the installers have asked for a 500g dpm to be put down on top of the 100mm Celotex, so do you know whether the Laminon UFH Grid membrane could be used instead of that?
You would be best to give the underfloor heating store a call for the best advice. Thanks.
Not seen much coming up from you Allen. Hope all is well with you. I'm missing the content.
I have a few short style video,s. I need to get back on it. Thanks.
Well presented. Three questions 1) Total cost for the underfloor 2) Why underfloor in the garage 3) Running cost.
Total cost, This installation was main done for video purposes so you would need to contact a local installer. i am guessing that answers 1 and 2, Running costs will depend on the heat loss of the property.
Allen your a champ 124k subs I remember when it was a like 3/4k congratulations brother.
Thank you very much for all your support.
Thank you very much, your video helped us a lot you the best
Thanks very much for your comment, please consider subscribing to support the channel 🙂
How much is the thickness of the screed??
it was quite deep, 150mm if i remember correctly.
Why did you favour a snake over snail pattern?
I did,nt design it but the loops are very small, less than 80m
pretty sure Grundfos don't like their Magna 1 heads fitted sideways like that
Why
@@AllenHart999 think the orientation helps them work correctly. Check the book, they aren't shown fitted that way
The chap is getting things for free as well as lot of reviews
I need help getting the point? The video says sponsored video.
Great vid.
Do you tee for the manifold off the primary or secondary.
Thanks.
I am going to connect it to the heat and hot water cylinder
@@AllenHart999 great. Thanks.
This is not good leeks
Why ?
@@AllenHart999 pipes start leaking and copper welds break off
@@SaqibJavid-l8w i have no idea what you mean.
Indeed, I prefer green beans.
Great video. We just had underfloor heating put into our bungalow. Taking ages, but it'll be worth it. Thank you for all of the videos over the years. Your videos really helped us make the right decisions on what to buy.
Thank you very much for your many years of support. Good luck with the bungalow.
