What’s the best pool heater for the colder months? Well, it it depends where you live and the size of your pool. If you live in a colder climate or you have a large pool, get a gas heater. It’s the most expensive to buy and to run, but it’s the most powerful heater. However, if you live in a milder climate, get a pool heat pump. These heaters will save you tons of energy. But it doesn’t work below 55°F. . . . #pool #poolcare #poolmaintenance #poolchemistry #swimuniversity #dyk #helpful #tips #po
