Tom, Calypso has had a Webasto T90 for 16 years. Late last year it needed its first tune up. We use the Webasto all year, even cruising in summer to take the evening chill off. We did install a "summer" valve that allows use to stop the hot water flow to the cabin heat exchangers but have rarely used it.
The T90 is able to make the boat's cabin as warm as we can stand. From a ambient 55/60F to 70F takes about 20 minutes. Installation was a 1/2 DIY, 1/2 tech from Sure Marine. We purchased the Sure Marine installation package that included step by step instructions and many of the needed fittings. The current draw is highest at start up. After the coolant is at temp the number fans (on high or low, 3 locations) and a circulation pump are the main current draw. Calypso's house bank is 4 6v batteries and the furnace can typically run 4 to 5 hours without a charging session. Running less heat exchangers/fans may extend the time. For domestic hot water we installed an "Everhot" heat exchanger that acts like a coolant reservoir and heats the water for galley and shower use. We are able to make as much hot water as what is in the boat's tanks. Most of the DIY installation time was running the coolant hoses and installing the heat exchangers. We had the pros perform the finish plumbing, wiring, and run the exhaust. The furnace itself is compact but the overflow tank and the Everhot tank take up some lazerette space. We ran the hoses thru the bilge. The fuel has its own feed direct from the tank.

So, every year when I go to the Seattle Boat show I gather materials and every the the amount of boat bucks, and my fear of screwing the installation up makes me put it off another year. Anyone have a hydronic setup?
