We installed a Webasto 90 ST on our Hylas 46 a few years ago and never loooked back. We are based on the west coast of Scotland and find it is effective all year round. We utiise a 5.5kw fan blower in the main saloon, and a 1.7KW fan blower in each of the foward and aft cabins. The forward and aft heads each have a small convector radiator and there is a heating coil in the calorifier. Lots of hot water and toasty cabins with warm dry towels.
Incidentally, boat used to be based in Carribean and came with reverse cycle heat pump air con/heating which I removed and installed the Webasto unit which is installed in aft starboard deck locker with exhaust through transom.

How big of a hydronic heater is needed for a Hylas 44?  I'm installing hydronic heat on my boat and want to size it appropriately.  How do I determine the maximum BTU needed?  Someone is trying to sell me a 9.0 Kw heater which equates to about a 30,000 BTU heater.   Is that size heater to big for a Hylas 44 living in the PNW?
