500 bucks of propane since November, for a 5400 sq ft house isn't really a whole lot. How much are you paying a gallon. Might only have used 180 gallons.

$2.41 a gallon, so 207 gallons of LPG. If I was heating with propane it would seem more reasonable to me. To heat water in two water heaters seems like a lot to me. This is with one person in the house taking showers/laundry.

If you were heating with only propane, your bill would be atleast twice as high.


5400 sq ft, 6 tons of heat pumps. Your propane use isn't real surprising.
You have 2 water heaters because it was cheaper then getting one really big one. And their water temp is probably turned up, making them less efficient.

I installed a hydro heat system in my home once. Had 75 gallon 75 K BTU wh. .I never liked it much..It takes away from your heat when you use hot water..I removed it about 3 yrs ago for a 90+ furnace

Hmmmm...but the heat pumps are electric, shouldn't I have a huge power bill too then? It was $200 for the month, including the two heat pumps, well pumps, septic pumps, probably less than normal lighting usage for my live-in painter, basic exterior lights on all the time, and electricity in the washer/dryer/fridge/dishwasher/stove/microwave for one.

The temp on the water heaters was set to the marking for "warm" (above vacation & below hot). Maybe this is normal LPG usage I may have to install a manual switch to cutoff the power to the recirc pumps, for backup heat. I don't think it is needed unless it is freezing out, and I suspect that is greatly increasing my hot water needs.

Shut the power off to the circs for your heat. And see how well the heat pumps keep up. Might be you don't need the hydro aux yet. Or it might be that you do.

Check to see if the heat pumps are set to lock out at X temp.

But at an indoor temp setting of 60 degrees, your electric doesn't sound like its off for having heat pumps with hydro aux heat.
