Ok, so I would need to know what temperature the pool would drop to. Do you know if it would drop to the ambient air temperature or could it get colder? Thanks
I need to work out the most cost effective way to maintain a swimming pool in a UK holiday complex that is closing for 1 month in January and hope that someone can help.
I would like to know if it would be cheaper to turn off the heating system for a month and then reheat it from base...
