This chap is going to go places. I'm extremely jealous ;) My Dad got me onto one of his vids whilst we are battle with our heating problems this winter. I love the pace, the amount of info, the humour. Top marks - you'll probably be able to retire before you're my age! Tsh its guys like you make me look bad to the missus! Keep up the good work!
do you not need a bypass between the flow and return before it hits the manifold? ie temp satisfied and three port goes to 100% by pass the boiler pump will be circulating against a closed head.
Nice video as always, but it is worth mentioning that you must lay polythene over the Ecotherm before the screed goes down.It is in the Building Regs. and I know how you love the Building Regs Also pumped liquid screeds are way better than trowelled down screeds. They are 5 times stronger so can be laid thinner and heat up much faster than sand and cement.
***** The polythene isn't the DPM that goes down first as you say but you them need to protect the insulation foil This is from Celotex:- A polythene membrane on top of Celotex below a screed or concrete oversight performs three tasks: it acts as a VCL; it prevents migration of the screed / concrete which can force the boards apart leaving cold spots in the floor; and (most importantly) it prevents a reaction between the wet screed / concrete and the foil face where gases given off can weaken the screed/concrete.
I know I'm late to this conversation..But the building inspector has said to me that they prefer to see a visqueen sheet under and on top of the insulation
hi there, may i ask, i will be fitting an electric combi boiler in my house for underfloor heating and instant hot water. my electrician will be wiring the boiler up, my question is this, is it within building regs for me to plumb the boiler in myself? i am not a plumber by trade but im pretty good at basic plumbing. also, does the supply and return connect straight to the boiler? i watch all your videos intently as i like to have a go at stuff myself and being a yorkshireman i like to save brass! thankyou
tt,an introduction to the work that will be needed on our house.The house,we were foolish enough to buy,will be using ground source heating as well as wood chip boilers and ,wait for it,solar just to add to the complexity Now I know why the builders are glaring at me whilst they should be glaring at the architect
hi thanks for your helpful tips, please can you tell me do wee need put heat reading sensors under the screed, our leaving room has 5 runs of 100meter pipe so it as you say 5 coils do i need 5 sensor of one? thanks
Hi Neil, you can just cap it off / have it capped off as long as there is still one radiator in the loop without a thermostatic valve on it as the heating system will still flow. Remember each radiator is typically a T off each of the boiler in and out line.
Im just about to install underfloor heating in my new extension. What are you thoughts regarding pipe layout? I was advised that a snail pattern is far better than a snake pattern, To be fair I haven't got the option as im using routed insulation boards with just a thin screed board on top.
hi james, thanks for the great videos. have you ever fitted low profile underfloor heating/ floating underfloor heating system. I want to retrofit ufh to my old house but not sure if these systems are any good. thanks Eugene
Bloody brilliant video!! I'm looking to install water underfloor hearing in my existing property which has flat smooth concrete floor; what fixtures will I require for installing the pipes from start to completion? 36 square meters over 4 rooms; lounge, dining, kitchen, hall; porcelain tiles going on top. Thx
Very nice. That tubing is very flexible. Are there any worries about it breaking in the concrete? What about if freezing temps are encountered and the boiler is shut down (extreme situation i know) would the pipe crack if the water in them froze or would it expand enough then thaw and work as normal? I'm in the states and the whole idea of underfloor heating is intriguing.
hi buddy another informative vid, I have enjoyed watching a few of them. A little question came to mind while watching your explanation of how UFH works. You drew a boiler, a pump and then the jocky pump attached to the manifold. Does the boiler not have a pump inside it already? Why the second flow pump? Thanks look forward to future vid's
Yes. It's easier in fact. Although just check your stat settings from the boiler. You just need the flow and return with one teeing off into a zone valve
Sorry , for this comment but the flow has to start from the window side thinkin about my experience , so like the system u used to put the pipe on the floor is inefficient cause the first half of flow will be warm and the 2nd (return )not !so if the 2 half of the return is on the window side u can't break the cold bridge...its better if u put the pipe with a spiral Form called also bifilar!!! More efficiency and a better heat Distribution on the whole floor. By the way you're talking about flow temps of 60 degrees in a floor heating sistem??? I guess ur clients will dance on the floor when they havent got any shoes on their feet ,did they?and the last thing u're talking about high tech, u think thats high tech?to regulate the sinular room temperature u put a Singular Electric engine on the manifold for every coil , that is connected by a room thermostate so u can even regulate the temp example 22.5 degrees in one room and 20 in another one for example only by adjusting the digital or analog room Thermostate. that is called high tech in my opinion coz u can.even command it with an cellular phone ;)i would be happy if u answer me Greetings Ad
Your layout is not optimum. It should spiral to the center until half the hose run is used up then spiral back out to the edge. Otherwise you get uneven heating because the first half is hotter than the 2nd half.

You are a star I have learnt a lot watching your videos... Next project is to install under floor in my new 6m extension.
Thank you, so helpful 🙂

This is a cracking video. Really well explained

Skill Builder Hi Guys, indeed. Although we usually put the DPM down first, then the insulation. PP!
***** The polythene isn't the DPM that goes down first as you say but you them need to protect the insulation foil This is from Celotex:- A polythene membrane on top of Celotex
below a screed or concrete oversight performs three tasks: it acts as a
VCL; it prevents migration of the screed / concrete which can force the
boards apart leaving cold spots in the floor; and (most importantly) it
prevents a reaction between the wet screed / concrete and the foil face
where gases given off can weaken the screed/concrete.
+Skill Builder good job the building inspector wasn't called in before pouring the floor ;)
+Jonathan Foottit
Too right but it is a shame. For the sake of a bit of polythene the screed is compromised.
I know I'm late to this conversation..But the building inspector has said to me that they prefer to see a visqueen sheet under and on top of the insulation

I’m having 75m2 of underfloor heating it’s got 5 zones. The floor I’m laying can’t exceed 27 degrees temperature. Will that be hot enough
Very informative, thanks for the info.
Cheers Dave, no worries mate!
keep up the gd work mate..... helpin me alot....
hi thanks for your helpful tips, please can you tell me do wee need put heat reading sensors under the screed,
our leaving room has 5 runs of 100meter pipe so it as you say 5 coils do i need 5 sensor of one? thanks
Is it economical to heat the floor using the water system than the electrical system?
hi great video. just wondering im wanting to get rid of my radiator, could I just connect flexi pipe to each end of the inlet and outlet .?
Hi Neil, you can just cap it off / have it capped off as long as there is still one radiator in the loop without a thermostatic valve on it as the heating system will still flow. Remember each radiator is typically a T off each of the boiler in and out line.

+Stuart Petty snail everytime
I would use reamer for pex pipes to shape the end of pipe before inserting the fitting, insted of hammering on the fitting part:).
How thick is the insulation unde the pipework?
can you explain the thermostat control? are there a sensor at floor level ,, or is it at the standard height around 5ft
+ndc81167 5ft is fine.

+unclepabs Man that's hard to answer without being infront of the job!
Will a plumber hook it up to the boiler or do I need a gas plumber because he's dealing with the boiler?
Very nice. That tubing is very flexible. Are there any worries about it breaking in the concrete?

Bounty B. Wolf Fine in concrete. Same precautions when it comes to plastic and copper pipe....always insulate!
Great video!. Congratulations!

You should consider getting a de-coiler. Makes things much easier when laying it alone
Cheers mate I'll see if I can get one.
Does the pump still circulate water during the summer, is the water drained, or is the water kept stagnent in the pipes?
+Adrian Papineau Kept stagnant as you put it. It won't go off as there's treatment in there (or should be!)
+plumberparts Awesome, thanks!
Quick question, what is the ideal maximum area for one loop on these systems?
100 metre in the pipe he using in this video
Can one run underfloor heating from a combi boiler ?
Yes. It's easier in fact. Although just check your stat settings from the boiler. You just need the flow and return with one teeing off into a zone valve
Nice
Very helpful thanks
No worries Binder! Sorry for the delay in replying!
Sub here please➡️👉 th-cam.com/users/plumberparts 👈⬅️If you haven't already!
can I have the underfloor heating with my combi boiler
Sharp. I like you. You for hire in Cali? Well great to be informed, hope is close to the systems installed here.
Alright mate been watchin your vids for a while , absoloutely brilliant,, Kris
Cheers mate, no worries!!!
Best video ever
Can the water be recycled like from shower water?
Austin E unless you are having a shower all day and it is really hot, it would be totally pointless
:-) thanks for the video. super interesting
