Under floor heating

[Hilly]

Planning early stages but planning a new farm workshop and id like underfloornheating , have any of you done it ? Is it do able workshop ? 150mm thick concrete floor ? Is it very expensive?

I would have thought that laying the floor is the expensive bit which you are doing anyway.
Got to use all that spare biomass heat somewhere

I dont have biomass im thinkjng kero central heating boiler . Just never had anything to donwith really wonders if any experts here rather than teeth sucking plumbers

I ‘think’ one of the things about underfloor heating is that it works best when you’ve good insulation. That might be a challenge in a workshop. Also unlike underfloor heating in a house where you can isolate/control the heating in non used rooms, you’d be heating the whole of the workshop floor. Depending on the size of the workshop may/may not be an issue.

Would i have to insulated under the concrete ? Id be using insulated box profile all over ?

Yes, 100-150 kingspan under your concrete slab

My experience is with houses, but basically thicker the slab the slower the response of the floor to a demand for heat as you have to increase all the slab temperature to raise the room temperature.

I get you , i think id just leave it running low for 5-6 months of the year keep the place temp-rate.

It takes a long time to heat the slab from cold. If you are in there every day it's not a bad idea although extravagant but if you just pop in now and then or even every other day you will be either wasting a lot of heat or it won't be warm when you want it to be. Great when on all the time in a house but questionable in a workshop depending how long and how often you are in there.

It will be used all day everyday , i have a man works in their , i like to be a good boss and make the place as nice as it can be for him so he stays with me . My current set up is ok but big stuff has to be outside its not ideal and its cold up here im top of the hill , i thought a centeral heating boiler only running it for winter only wouldnt be to savage ?

Well yes. You want a min of 4" under the biscuit and ideally only screed ontop, then you have issues of weight bearing for point loads.

Would take ages to heat up, but also should hold the heat well. Wouldn’t really be adjustable temperature as would take so long to react. Could be good to take the chill off.
You’ve also got the issue of reinforcing the slab if you want heavy machinery in there as you’d need loads of insulation underneath

Biscuit ?

 

[Timbo]

Biscuit ?

The biscuit being the floor slab

Got ya .

Do you put the pipes on top of the king span or in the concrete ?

 

[Steevo]

Taking this diagram showing UFH compared to radiator/warm air heating, there would be a lot to be said for UFH in a tall building like a workshop. Keeps the people warm instead of heating the building from the top down wasting a lot of heat in the high air space. Would keep feet nice and warm too compared to being stood on cold concrete.

 

[Timbo]

Do you put the pipes on top of the king span or in the concrete ?

Entirely depends on the use of the floor as to how you construct it.

Pipes on top of 100mm kingspan , then 68mm floor screed layed by hand , this is not cheap
Big plumbing job
