Hydronic air conditioning

Hi All,

A boat I'm considering already has a Webasto hydronic heating system aboard. Thus, the fluid lines and air handlers are already installed throughout the boat. I'm interested in adding a water chiller (chiller, control valves, etc.) to provide air conditioning as well. Does anyone have experience with such a system? I'm early into this quest, and can only guestimate at this point that I'd need something like 8K BTU for the forward cabin, 16K BTU for the salon, and another 8K BTU for the aft cabin. And the boat only has an 8KW generator for power, so start-up loads are an issue. Boat will be primarily used off the dock at anchor.

Given I'm in the PNW, use of this system would be rather infrequent, as there really aren't that many really hot days afloat. However, there's been several instances in the past where we've been driven indoors by heat, BLACK FLIES, and no breeze. No bueno combination.

Regards,

Pete
