It is more efficient sometimes. I can just blow in ground heat into the inputs of all of the stuff when it's colder out but when it's warmer out it isn't more efficient (for the water heater) .. but it is for AC units as ground here is 49 degrees at 8ft (pretty average for the global temp that low)If you are going geothermal then I would look into heating your water with the geothermal heat pump. More efficient.
Yea but they should make the non-hybrid 240v too so it balances on my solar4500W heating element so 18A per leg.
wow... so the real option is to get hybrid for solar and just set it to only use heat pump lmao wtfUses 240V for compressor, about 150W per leg, I just checked.
they don't even have ONE option that is heat pump only and 240v
It must be marketing.. wtf I just emailed them asking whyGood question, don't know. I looked at compressor size and did not see any difference. I would not buy a heat pump only unit. There are times when the heating element can work well as a dump load or quicker recovery. End of the day battery bank hits full charge and heat pump water heater is not 100% full of hot water. Just switch over to the heating element to dump excess PV.
usually in my experience anything that is "hybrid" and does "multiple things" is more expensive than 1 single thing that is simple.. but then if you buy a bunch of single things to do what the hybrid does then they're overall more expensive.. tools for example
these heat pump water heaters are very weird prices.
& yea the dump load is good. I got a hot tub for that but can prob put some lines on the hot water heater and have a heat pump hot tub lool to throw all that heat into the air.. maybe not a great idea
but yea it seems the 240v is the way to go, worst case I can throw some elements on it that are like 1500 watts instead of 4500 and as far as I see no water heater runs both elements at the same time so 1500 is a bit nicer than 4500 for my system. rheem seems to have tons of elements to select from
thanks for the info on the 240v compressor that really makes the purchase easy
