I'm also in the market for one of these for a loft conversion. I figured I may as well get it up while the scaffolding's still there. I'd be interested to hear from anyone with experience of these things. What are reliable makes etc. and what to watch out for.
The one you link to in the OP looks a bit pricey - I found this site that could save you some dosh, but I don't know if LG have a better reputation. Also, 2.6 kW (not Kw btw) sounds a bit small for a 25 m2 conservatory. (Though I wish they'd quote volume and not area - our loft will have a low ceiling so I would think a lower requirement for cooling than a high-ceiling room of the same area.)

Dursley,

Our conservatory will have approx. 65 cu.m internal volume. According to the website you linked to, we would need 18,000Btu (based on area)! This unit would be 4" longer than the unit we was looking at, and not much different in height nor depth.

I know the units should be kW not Kw but I pasted the link from the website itself - I note it is correct in the Technical Details listing.

This is the sort of discussion I was looking for on these units. As you ask, which are the reliable units? LG appear to be reasonably priced when compared to the other on the website - Toshiba, etc.

Thanks,
John

Theres some good discussion on the forum about using air source heat pumps for heating. It seems that the figure you have to look for on these aircon units is the COP - the higher the better with some over 5 available. For example if a COP of 5 is achieved (very much dependent on outside air temp - the colder it is outside the less heat can be extracted from the aid) it means that for 1kW of electric you get the equivalent of 5kW of heating. Also look for an inverter-type, meaning that the compressor speed is variable, rather than 'on-off' I think.

Try this thread for starters!
