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.
You can run a heat pump at night as long as the ambient air temperature is over 45 or 50 degrees. The lower the air temperature the less efficient the heat pump. Heat pumps convert energy from the surrounding air into heat for the pool. the warmer the ambient air temperature surrounding the heat pump the more energy efficient the heat pump is. Running your heat pump during the day is more efficient, than running the heat pump at night.
