What time frame was the 3375kWh for? You'd have to be paying $.30/kWh for that to be a year's worth of power for your water heater.
How much has the kWh/HDD for your space heating increased with the heat pump water heater?
I use a Curb to get real-time energy usage.
The traditional unit showed on average a 45
minute recovery time at 4500-4900
watts, since this is less than an hour, I first multiply 4500
by .75
to get 3375
watts for an hour, finally I divide by 1000
to get the 3.375
kWhr.
The new system runs for 3 hours, using an average of 350
watts, so I first multiply by 3
which is 1050
before I divide by 1000
to get the 1.05
kWhr.
This is 69%
decrease in consumption each time the system runs to recover.
The system runs to recover after showers, baths, and dishwasher. 3-6 times per day.
Hi - Thanks for the good info. We're in Eastern CT as well, near the shore. We run a dehimidifier pretty much all summer. Will the hybrid system really eliminate the need for it completely in a humid unfinished basement? Also, in winter, how cold did the basement get? We'll put it next to the boiler, and I'm guessing it takes all that heat out... Will it be freezing when we go down to do the laundrey?
