Underfloor heating in a plant room

[Lincolnshire Ian]

Hi all

We are planning a new build with a plant room. The plant room is accessed from the garage, but is part of the insulated building envelope.

The plant room will contain the ASHP internal components, MVHR, battery, UFH manifold and Hot Water Tank.

Most of our UFH quotes exclude the plant room, which has a certain logic because this is a small room which contains equipment that will generate heat. 

Does this make sense, or should we be asking for quotes that include UFH in the plant room?

Thanks

We haven’t UFH in our current plant room 

Five years ago in our previous build I didn’t give it a thought and included UFH The PR never dropped below 19 So the heating never came on 

So it may be a case of better have it and not need it Pretty much like bedroom radiators in a well insulated house

If the ufh manifold is in there, then the pipes will need to travel across this floor to get to the manifold, just add a couple of extra metres to one loop and wiggle it across the bits not already covered.

Makes perfect sense, you are generating heat in that room with the equipment, floor is heated via the pipes that traverse under it etc.

 

Same should be true for hallway etc. divert pipes through utility also, that room doesn't need dedicated heat either.

 

Our plant room is the roof (fully insulated room) never cold in there.

My "plant room" is under the stairs and it's damn toasty where everything converges. Basically it has UFH as a by-product of such.

We have UFH in ours, but it never comes on naturally due to ambiance. You do notice the cold floor in there mid winter when you're doing the laundry though, first World problem, so I boost it (we're zoned per room) on the cheap rates just for a couple of hours to counter act this

Simple.  Don't fit a dedicated UFH loop for the plant room, but lay the connecting pipes to other rooms spread out as if they were actually used for heating (not all bunched up together as seems normal)

 

And for no extra cost or effort you get some heat into the floor of the plant room whenever any other room is heating.

Do the same in the hallway
