UFH with air source heat pump

slav · Nov 11, 2013

Hi we have a large garage and small office on the bottom of the garden, there is no gas only electricity.
I'm thinking about fitting under floor heating powered by the air heat pump as i already have one 8.9 kw(left over from above ground swimming pool need to check if this is suitable for running UFH)
I'm trying to find some more information on the system design with no much success, everything seems to be in combine with already installed boiler.
We want only used this for UFH no hot water or else.
Could anyone could advice on this topic, if someone have any drawing that would be wonderful.
Thanks
S

Speak to the manufacture or a local installer. Heat pumps are perfect for UFH but they need to be done right.

only work if your garage has been converted to double skin and fully insulated throughout

75mm foil backed insulation on single brick skin beats filled cavity any day 🙂 That's what my office is - Snug as a bug🙂

Design is pretty straight forward (we do it every day 🙂 ) Just need to know heat loss of the building(s) and floor construction(s) can then work out the UFH design and heat pump sizing. p.m me or link via my signature.

Think about putting some PV on the roof as well and the income from the PV could pay for the heating 🙂
