Heat Pump â The heat pump is built into the AC and works great if you use it correctly. From my experience and mistakes Iâve learned a lot about this little heat pump: 1. The Heat Pump does not work when temperatures are below 45 degrees. 2. Do not attempt to run the heat pump when plugged into a 20a outlet, use the heat pump when youâre plugged into a 30a or 50a plug. 3.
When your heat pump set between 18 and 20 degrees inside, and the outdoor temperature is minus 10 or better, youâll find this heat pump will be on approximately 60% of the time. In hours this looks like 60% x 24 hours a day = 14.4 hours. To calculate the actual cost to run your heat pump for 14.4 hours a day we next need to compute how many kilowatt hours the heat pump is using. Calculating Kilowatt Hours Used Per Day. Kilowatt hours is what Nova Scotia Power bills their customers for.
