Types of heat pump

The difference/benefit is that there is no restriction on the size of the 'heat collector' - as is the case with ground source, put in as many loops as you want.

Ok, in the case of the Daikin they provide a pre-built external box, presumably with the typical heat matrix, fan etc. but it's the idea of being able to effectively use the ground source principle of 2 'water' circuits + the closed loop refrigerent circuit that has me interested..

The size limit of the heat collector (evaporator) goes away for air-source, which is the limiting factor when hacking, so, logic says, if it's big enough it isn't all going to frost up. Where I live there is no possibility of ground source due to the amount of rock so air source is the only option; fortunately I have quite a lot of roof area that I can experiment with. On one website I did see mention of a 'fence' collector - same sort of thing I guess.
