Underfloor heating - best way to ensure rooms are warm in evenings?

record · 03-09-2008 02:26PM #1

Have just moved into a house with underfloor heating and an air-to-water heat pump. All going well so far.

The engineer has set the underfloor heating to come on at night, to avail of night-rate electricity. The digital control for each zone is set for 23 degrees at night and 17 during the day, which gives a comfortable 20 degrees or so for most of the day. However, the place could do with a bit of heat in the evening time, say from around 8-10pm. What is the best / most efficient way of doing this?

Thanks for any advice.

Depending on how you use the house - your secondary heat source may be best . If you all a hang out together in the same room in the evenings - use the ( assuming you have one ) gas fire or wood fuelled stove

I don't have a secondary heat source!

Well your response time should be pretty quick as your slab is always 'on'. So the only way I would see of boosting the heating is to program the stats to 20 degrees from 7pm-9pm?

Other than that, how well is the house holding the heat thats generated? Have you good U Values in the floors, walls, windows and roof space? Have you any uncontrolled ventilation ie draughts?

I find that just turning on the TV & lights is sufficient to warm the living room.

Hi Record,
remember that if it is a newly built house and especially if concrete built that it will be drying out during the first yesr so this may be a temporary phenomenon (during the 1st heating season).

On a related note, can somebody set me straight on why you program a heating system to be highest when you're in bed and lowest when your body is generally tired and needs the extra bit of heat (ie evening). I know that it is because of the nite-rate electricity but still I don't get the logic.
