I currently have a 15ft intex frame pool with a 5kw air source heat pump connected. I'm running it 12 hours a day which is getting me a steady 26 degree temperature. I'm in the UK and the night time low at the moment is 11 degrees. So I imagine I'm losing quite a lot at night.
I have a blue/gold solar cover on top. Just wondering if anyone has any ideas on how i can insulate the sides of the pool? I was thinking some kind of foam sheeting? and taping it on? I don't mind how ugly it looks as long as its efficient? Any suggestions? Thank you all in advance.
