Texas heat is hard to bear without an occasional dip in the pool. But, in spite of the sweltering temperatures outside, you may still choose to warm the water to make it comfortable for swimming.
Most people heat their pools with a gas-fired heater that uses either natural gas or propane. While these appliances constantly become more efficient, pool heating costs can still skyrocket without a solid conservation strategy. So follow this plan to heat your pool without burning your budget:
- Use a pool cover to reduce evaporation, which accounts for 70 percent of a pool’s heat loss. The chart below shows estimated heating costs1 from April 1 through Oct. 31, with and without a cover.
- Set the temperature between 78 degrees and 80 degrees. For every degree you raise the temperature, you could pay up to 30 percent more in energy costs.
- Lower the thermostat to 70 degrees when you won’t use the pool for a few days. For longer periods, shut the heater off.
- Opt for a timer on the pool pump. You can shorten the running time while still maintaining clean and sanitary water.
- Install a fence or hedge to protect your pool from wind and heat loss.
- Have your pool heater serviced annually by a qualified technician to help it operate efficiently.
- Consider solar heating. It may be a more affordable way to maintain the warmth of your pool. This type of insulation minimizes heat loss and holds water temperature steady.
If you recently installed a pool, contact Customer Service. You may require a different meter to accommodate the pool. The correct-size meter could also eliminate potential efficiency issues.
