A bareboat charter outfit in Anacortes lists a 34' CHB with a heat pump as the cabin heat source. I've not heard of such. What is the motive power for this heat source? 110? 12V? Diesel? Both a.c.'s in our motorhome have reverse cycyle heat pumps on them, but these require 50 amp. shore power or the 7.5 kw genset to run effectively. Thanks for your help!
