Some neighbors asked my company for a bid on a solar pool heating system for their in-ground pool in Maine. They were hoping for a low-cost solution to raise their pool’s water temperature.
Before starting a detailed estimate, I asked if they had a solar pool cover. The customer pointed to a shed and explained that the blanket had earned its spot there by being too inconvenient to handle. I touched briefly on the evaporation losses in pools and encouraged them to use the blanket more often.
They were a little hesitant until I explained that they could spend several thousand dollars on a solar pool heating system, or invest $200 in a reel, which would make handling the blanket far easier.
A couple months later, I ran into one of them again. “The blanket works like a charm,” she said. I don’t think they even bought the reel.
