    Yes in electric .in county gas is costly . Propane. Engineered heating fuel .if yellow stickers correct on mine I don't mind that cost going to other styles of electric heat pump etc costly long Roi. My water heater in living space and that's heated with wood stove water going into water heater is about 74 degrees.

    Agree. When you live away from the city and have no natural gas, electric is often less expensive than propane for water and home heating. With an electric water heater you have no wasted heat assuming it’s inside and you have a trap on the output. For the house you use an efficient heat pump and seal up the enclosure, especially the attic. Old school houses like mine have a wood burning fireplace for backup.

    My personal experience is only with gas heaters. In terms of corrosion there really shouldn't be much difference (water, metal, heat, does not matter what makes the heat). In terms of sediment the electric ones are easier to deal with because an element can be removed to give much better access to the bottom of the tank. For instance, afterwards let it dry and just vacuum out the sediment.

    Yes when it's cold and worthy in the temperature then my progress hybrid wood stove is running until well hopefully spring I can't do any better than that as far as heating goes and just takes a while to get that cold here in the Carolinas My heat pump works quite well down to even below freezing but when it's below freezing or right it freezing it's just as cheaper to run the wood stove and I get more heat ridiculous more heat and no strain on my electric bill more or less

    The new inverter based heat pumps can achieve abundant heat in below freezing ambients by ramping higher than their nominal 100% rpm while utilizing electronic expansion valves and vapor injection. These are now widely available for conventional split system retrofits using air handlers and conventional thermostats. Pricey but effective.

    My twenty year old two speed compressor (48k btus) gets by and has 15 kw (52k btus) of supplemental electric heat for the now common days on end ice storms in central Texas.

    How has this thread pivoted to an off-topic discussion of home heating systems?

    It was already starting to happen by #13.

    It actually makes a more linear kind of sense than a lot of examples of PriusChat thread drift.

    The usual suspects

    Tom and I go with the flow. Besides I tried to pivot using inverters in both areas.

    It goes a couple posts further back ... aluminum vs magnesium anode rods came up because the aluminum ones make the same goop that can clog the aluminum coolant channels, leading to a "pump running but not flowing".
