A few bits of info first about our trawler usage. Never on shore power, about 80% anchored often for days at a time, located in 45 deg. N, 1600W solar, 700Ahr AGM (actual), 9kW genset, 15 gal hot water tank, all electric boat. We do not use the genset except when solar does not get us to 100% or very close or when we run a large water maker. Our heater is plumbed into engine system.
On a good solar day we can get to 100% SOC with no problem. On a very good day we can heat the water tank as well. The problem is the tank rarely gets fully used in the same day and by the next day is not warm enough for showers as it has partially filled with cold water.
I am considering adding a 1500W 3 gallon point of use heater (not a tankless heater) in the head plumbed into the hot water line. From my calculations, we could power that for 20 minutes twice daily for a relatively small consumption compared to the 15 gallon heater, getting two showers and not wasting water to get the hot water flowing in the shower.
Any experience out there with these types of heaters or comments for or against.
Thanks
