Hi all,
I'm building a small garden room and have only just begun to speculate what heating I should have. The room is only 2.2m x 3.2m and 2.2m high. We have laid a concrete slab and will be laying 75mm Kingspan foil faced PIR insulation and then 50mm screed. I originally thought I'd have a wall mounted convection heater or something for the colder months, but have just realised that an electric underfloor heating system might be an option because we haven't yet done the screed.
My understanding is that at about 6.5m2 the power draw might be about 1.5 - 2kw. Is that about right? If so, kw for kw how efficient would a basic screeded system be in a room of this volume (about 15.5m3) compared to a convection heater of similar power. Does the underfloor system have obvious benefits of economy or warmth, or is it just neatness?
The walls will also use 75mm Kingspan and the roof 100mm. The windows are all double glazed naturally. Other than that I have no heating plans yet.
Unfortunately I just bought laminate flooring today, and if I was to do underfloor heating I don't think that would be the ideal choice.
Thank you for any advice!
