My take so far on this great discussion about heat pump hot water heaters (HPHW's) for domestic hot water:<br>
A HPHW powered by off-grid PV could be very effective, if there was a timer which controlled it to only operate during daylight, so it doesn't load the batteries at night. And the HPHW cools and dries the appropriately large space where installed, which food, beer and batteries are stored.<br>

> The water heater heat pump tanks , I am referring to are ONLY FOR HEATING DOMESTIC HOT WATER for washing clothes , showers , baths , and dish washing . On April 15 the Feds mandated all new standards for water heaters , ALL ELECTRIC AND GAS HOT WATER HEATERS ARE NOW ABOUT TWO INCHES IN DIAMETER AND SIX INCHES TALLER that were MANUFACTURED AFTER THAT DATE . All 66 , 80 and 120 gallon electric water heaters were OUTLAWED except for Solar Hot Water Tanks and 80 gallon water heater heat pumps are allowed . The normal size 30 , 40 , and 55 gallon electric and gas water heaters are now wider and taller ! Water heater heat pump tanks are usually 55 or 50 gallons or 80 gallons and have a heat pump only , hybrid ( heat pump and electric ) , electric only and off modes - for vacation . The idiot Feds think they should be used all over the USA , however , my research , sez to only use them in hot humid climates in garages ( which they will cool and dehumidify ) in climates in the<br>

> ot humid south and East Texas . Do your own research , or look at the research done at the Florida Solar Energy Center . GatorTom PS : rumor has it that the Feds may rescind the order from their hot water Czar on 80 and 120 gallon electric water heaters ! Or maybe they will send SWAT teams into plumbing supply houses to check on that and also their outlawing brass fittings with tiny amounts of lead .<br>
