I was at a friend’s house over the long weekend. They just moved into a new place here in Stamford, CT. While I was admiring his new HVAC system and specifically his condenser units, I noticed another unit next to them. It looks like an over sized condenser unit, with large coils. But this one had a digital panel on the front of it. When I asked about it I was told it’s the pool heater.
The unit was a few years old. I asked him who serviced it and I got a blank stare back. The coils on this unit were clogged with the standard debris found in dirty condenser coils – grass clippings, bug remains, dandelion seeds.
I found this great image on how the pool heater works. It’s from the site called solar direct. Click the image to go to the original site page.
