Chiller to heat pump

[The MG Pony]

I pretty much doubt that present evaporator could be used as condenser in heat pump mode if one simply add 4-way valve and nedded electronics and other parts.

Hmmm true, depends largely on what type of heat exchanger he has. I do think I mentioned he'd have to check that though.

I have converted Window A/Cs to heat pumps with good success, I rewire it so in heating mode the fan will be locked into full speed and usualy keeps head pressures resonable. but it is mostly manual control, hence why I mentioned he only should try if he has deep understanding of it.

I just wanted to emphasize that.
