Opinions on ebay heat pump

[Boxerman]

In the process of building a nex extension and thinking of running underfloor heating combined with an air source heat pump. Extension is 2 storey, kids playroom downstairs with 2 beds and a bathroom above, total floor area around 65-70 sq metres. Currently on oil heating so would like to consider cost effective renewables.

I don't recognise the manufacturer personally I would not touch it!!

If you consult a MCS registered installer you MAY be eligible for a Grant for Installation and operating which would save you money in the loneger term
Beware many air source heat pumps are NOT very efficient in low outside temperatures (0'c and below) many then rely on a 6+ Kw Immersion heater for back up!!

What you want is a dx earth coupled system.
masser install them..

Though I expect not in the uk as were backward here to such technology.
Much better COP (1:5 possible) and SPF then glycol systems.
A few even have the condensor pipes buried as underfloor heating.
No pumps needed, no antifreeze, no heat exchangers...Therefore, you can evaporate +/- 6K higher.
Thermodynamically much more superior. The plumber loses his job though as its highly specialised.
Only know of one though and seen it running which was a diy job by a fridge tech where he modified a supermarket condensing unit.

Rethink a little bit.

Buy the air source heat pump but have the oil
and air source heating heating something like a heat store
or as two boilers as a cascade.

Quite a lot of the year the air source should be able to
do the whole house. In colder weather the oil will kick in as a booster.

When it comes to air source heat pumps the quality names are better
but the MCS ones don't justify the extra premium. Prices will come
down and you can replace in the future. When it comes to it an air con unit
is just a compressor, condenser and evaporator so very simple technology.

I see you are in Yorkshire. If you are anywhere near Doncaster send me
a personal message been looking at installing one of these units for a while now.

Never sent a personal message, how do I do that then

Buy a container of them from China and stick your own name on them....Grrreat!

Need parts or tech support? Dream on!
