Wet UFH how to retro fit an electrical heater element?
It's March, sunny but cold. Yesterday my PV report shows:
System Production: 41.7 kWh
Self-consumption: 25.74 kWh
Export: 15.97 kWh
So I'm exporting lots of unused electric (once my UVC is satisfied) and then late afternoon we fire up the log burner and the central heating comes on. Daft this when I could use the PV electric excess to warm up the UFH instead of expensive LPG via a Viessmann boiler.
Looking throu
You shouldn't be running around at all....it's massively overrated
Havent you already got 2-port zone valve(s) fitted for the space heating and the uvc ?
If so, just fit the Willis heater into the UFH return, at the manifold ( eg before any other parts of the system tee in / out of the UFH primary pipework ) and then tee the return back into the UFH flow via another 2-port ZV. That way the hot water created by the Willis heater travels the shortest distance and doesn't risk any nuisan
