I have a hydronic system with a diesel powered Webasto furnace. It heats up the hot water to scalding hot and the boat gets really toasty. I'm a liveaboard in the PNW and coming up on colder months so I'm just wondering about the feasibility of using my electric hot water heater instead of the diesel furnace. Has anybody tried this? I think I could probably hook up the circulation pump to work manually or even via thermostat. I'd love to hear what you all think. It might even be cheaper than diesel (and far more convenient than hauling diesel down the dock all the time.)
