#circuits for Underfloor heating in 21m2 conservatory
So we are having a conservatory put up and are going for gas to water underfloor heating. It will be 3m by 7m.
Any experts on here know how many circuits will work best? Plumber is saying one. Is this enough?

Depends on the type of UFH you're looking at. If it's going to be 15mm pipe, then 1 circuit should be enough (assuming also that
it's going to be 100mm screeded over). If you're looking at 12mm pipe, you'll need 2 circuits.
May I recommend here
I confess I do have a vested interest here, as I work in product development for the UFH division  .
If the conservatory floor is already down, use the 12mm pipe Overlay system, it's hard to beat. If the room is not yet built, consider red floor
plate with 15mm pipe.
The other thing to think about is don't expect the conservatory to be lovely and warm in the depths of winter, the heat loss of all that glass
is too much for any UFH system (despite what some salesmen might say!!) It will, however, extend the useful period of the conservatory by a good few
months.
If you need any more info, let me know.
Obviously all of the above is in my opinion and not endorsed by the company I work for

I used the Danfoss consevatory UFH system in my kitchen. It works in parallel with a normal radiator system in the rest of the house and doesn't
require manifolds etc. In fact I didn't use their system I bought all the bits seperately and saved about £100  It's pretty simple, just
uses a return-temperature valve to control the heat. I used a single 15mm counter-flow circuit.

Thanks guys, sounds like it will be ok then.
I know what you mean about all year round being unachievable in a conservatory, so we will see how it does.
Cheers!
