Gaf Posted February 2 Posted February 2 Read a good few posts on this. Original plan was electric towel rails but electrician put us off (can't recall why) and suggested we have the UFH feed into towel rads. More reading suggests this isn't necessarily the best as UFH flow temp in our house is estimated at ~22 degrees. Gonna test 22 degrees myself with my hand but curious if 22 would be now where near sufficient for a towel rail max temp?
JamesP Posted February 2 Posted February 2 (edited) I would install electric towel rails on a timer. We have UFH upstairs and have never needed to use it, the electric towels are adequate in our circumstances. Edited February 2 by JamesP 2
Gaf Posted February 2 Author Posted February 2 Just realised my question isn’t too bright… sure the room temperatures will be ~21 so how would a towel rail at 22 do anything. It would have to be electric

Seems to be very common not to put it in alright.
Bonner Posted February 2 Posted February 2 We have towel rads tapped off the DHW circuit from our ASHP. Flow temp is 50 deg.C and they come on winter and summer. I turn them down a bit in the warmer months, this works very well for us. 1

Russell griffiths Posted February 2 Posted February 2 If you tap it from the wet ufh how will it get warm in the spring / autumn to dry your towels 3 towels rads here all electric wired back to remote timers in the plant room so no ugly timer on show.

Expand Brilliant idea. I like that. I’ve been playing with a Shelley dimmer, and I think that their switches would easily handle the current for an electric towel rail so will use something like that for the timer function rather than clockwork so it won’t drift off on time. Also good for holiday mode.

Expand The electric towel rails just warm / dry the towels and add a little heat to the room. I think I would consider electric UFH in the bathrooms next time.

Expand Genius. Wouldn’t have thought of that. Just to make sure I’m understanding it. Is the water from your DHW tank pumped through a separate ufh pipe connection to your bathrooms? Do you find the floors heat up quickly enough since it only kicks in to heat the floors when you’re showering?
Bonner Posted February 2 Posted February 2 Maybe a picture would help … it’s the heating fluid which is circulated, not hot water from the tank. UFH heating is controlled separately.
Andehh Posted February 2 Posted February 2 (edited) We have towel rails off the UFH loops, on their own timer, and have them come on for a few hours middle of the night when we are guaranteed UFH is ok, otherwise they short cycle the UFH. For 35 degrees for a few hours seems to finish off the drying of the towels. Want to fit even bigger/denser towel rails, but not important any time soon. I'd have gone for electric towels rails if we did it again, and electric UFH mats as well as wet UFH. Edited February 2 by Andehh
