Radiator on UFH circuit

[Robb086]

We’ve recently installed UFH in our first floor extension using Nu-Heats spreader plate system.
 

Long story short, the plumber missed the small print which specified that additional heat sources were required in the bathroom to get it up to temperature, so we’re now looking at the best option for plumbing a towel rad.

Plumber wants to simply run a new central heating run in and drive the rad off the main hallway central heating stat, however given the bathroom is setup as it’s own zone with stat etc, that seems a massive waste. Is there a way to run the rad and UFH off the same room stat and zone?

 

Is it possible to plumb the rad into the end of the UFH loop?

Probably not.

Do you know what flow temperature you'll run your UFH at? 30-35°C is normal, although in a very well insulated home we find 26C is plenty

 

You say the towel rad is needed to get the room to temperature, not just to dry towels, which is already a tough shout as towel rads generally don't deliver many watts of output. But at 30C you'll get diddly squat from it, in terms of room heating

 

You can run a new feed and put an electronic TRV or zone valve on it that is controlled from the bathroom zone stat.

I would fit an electric only towel rail.
