I know this topic has been discussed a billion times but I can't quite seem to get a specific answer to the intended purpose and usage of a hydronic heater in a liveaboard
We are a dock
(for now) in Victoria — the PNW Victoria — and will be here most of the winter. It's a 38' sailboat with a huge aft cabin
and no insulation
. To date, temps have been generally above freezing and we have only lost
3 pillows to mildew before we learned not to store them against the hull
We have a Webasto 90s hydronic heater and three radiators: V-berth/salon, salon
, and aft cabin
but, under advice of the fellow who sold me the boat, we don't use it and instead use a Camfaro electric
heater and a smaller (cheaper) electric
heater in the aft cabin. The result is hot spots and cold spots and the occasional breaker thrown when I wimp out and run things full blast. (See this thread
To date, the only time we have used the Webasto is during the summer up in the Broughtons on cold rainy mornings for an hour or so to warm up the cabin and this morning when I thought I would try it out. Turns out it heats the boat way more evenly and quietly.
So, the question(s).
Despite reading a ton of stuff I have yet to learn anything specific about the Webasto's intended use, duty cycles or day-to-day maintenance
Is it intended to be used 24 hrs a day when its cold enough to warrant it?
Or for 7 days a week for three months?
Does it need more than a yearly checkup?
I realize (or at least have been told) that using the electric heaters saves wear and tear on the more expensive Webasto, but I have little understanding of what that means. If they were originally truck heaters shouldn't they be able to stand hour after hour and day after day of usage? Or am I better off leaving it as an emergency
Enquiring minds want to know!
