If you are looking for a way to heat your pool this fall, you have probably checked out our solar heating options. They are great for increasing temperatures 10-15 degrees, making fall swimming possible. So what if you want to keep your pool open during the colder winter months? Pool heat pumps are a fantastic heating option for cold weather swimming.  They draw heat from the surrounding air to warm pool water and will function in very low temperatures. Automatic defrost allows heating with outside temperatures as low as 35 degrees! They are also much less expensive to operate than natural gas heaters. You will be pleased all around with the efficiency and power of a pool heat pump.
