First floor UFCH versus Radiators


Balou

Recommended Posts

Hi, we're due to start breaking ground on a new build in a couple of weeks. Heating/hot water will be via an ASHP (no gas in the village). Ground floor heating will be UFCH but still unsure as to go with Rads or  the between joists spreader plate UFCH for the first floor. Can anyone share their experience of warm up times etc for the first floor. We  have an ASHP in our current (built in the 1700's) house, in which we have UFCH in the ground floor (well insulated) extension and rads everywhere else. Its very noticeable that the rads have much quicker heat up times than UFCH areas. Re ASHP/UFCH firms, has anyone any experience with epc improvements in Chelmsford? TIA .Phil

In a new build you would hope that the level of insulation included means warm up times will not be an issue.

 

In our previous house, built in 2004 that had UFH upstairs and downstairs.  It was noticable that upstairs took longer to warm up mainly due to carpets slowing down the rate of heat transfer (solid floors downstairs)  In our present house, it is so well insulated we do not have any heating upstairs.

 

If you choose radiators, they will need to be over size / low temperature, to work with an ASHP.
