I now have an electric hot fwater heater that I use but also have an indirect water heater (now drained) off the oil boiler. I'm wondering if I should heat the hot water with the electric with the 7.5kW generator, or fill the indirect tank and run that. I'm not sure how long it would take to heat the hot water with the generator, esp. after a couple of days when the water gets colder. So, that could use more gasoline, but it'd be a little hassle to turn some valves and fill the indirect, which could be powered off a small genny. Plus, I can't run the well pump at the same time as the water heater, so that'd have to be switched. Ideas? Experiences? Thanks.
