What size heater do I need for my pool?

Heater size is measured in BTUs. As a general rule, you need 100,000 BTUs per 10,000 gallons of pool water, but this varies based on your climate, whether you use a pool cover, and how quickly you want the water to heat.

Gas heater vs. Heat pump: Which is better?

Gas heaters heat water quickly and work regardless of air temperature, making them ideal for quick heating and colder climates. Heat pumps are more energy-efficient and cost less to operate, but they rely on ambient heat and work best when air temperatures are above 50°F.
