By now, most of you who have been following my threads, and know I bought the CB 5036 to replace a woodburning stove. The woodburning stove was to reduce electric use of our heatpump. The addition of the DHWX was also to reduce my electric load.
What you didn't know was that my house was an electric hog! Other than the telephone it's the only utility I have to pay for. I average $200 a month.
My electric load (Pre OWB) consists of The Well, Sand Mound pump (Septic system) , Street light, sump pump, 2 Fridges, one freezer, Dryer, HWH, Stove/Oven, heatpump, lights, TV's Ect. I was using 74 kWh a day!
During the last month I changed the load. Added the OWB and DHWX. Removed one fridge and downsized the freezer (Both were over 20 years old) from a 16 cu ft to a 7 cu ft. They read my meter on the first of each month, so until I get the electric bill I could not see what I was saving. I know now! I take the current meter reading, subtract what I was billed and divide by number of days used. I'm down to 22 kWh a day!
I'm going to miss winter when I shut down the OWB.

I added insulation to the attic in November raising the R factor from R19 to R40. Hopefully I'll see some savings when the AC gets turned on. It won't be as mush as with the OWB, but at least our summers are short here in the mountains of PA. And of course the HWH will be on electric again., but at least it's on a timer.
