We know you want to hold onto the swimming season as long as possible, especially on those beautiful, but cool fall nights. Here’s a heating lesson that will help you heat your pool efficiently. Heating Options For pools, the choices are gas heaters and heat pumps. Gas heaters are better suited to raise a pool’s water temperature fast, but heat pumps are far more energy efficient. Hayward heat pumps can save you up to 80% on your energy costs by using heat from the surrounding air to heat the water. They’re quiet and durable even in harsh coastal environments and are an excellent, energy-efficient solution for maintaining a constant temperature vs. the quick heating of a gas pool heater. Hayward’s gas heaters can save up to 18% on energy costs because of their advanced hydraulics and feature low-NOx emissions making them a perfect choice for environmentally-concerned pool owners. They’re ideal when you’re looking to heat your pool water temperature quickly. Small electric heaters are great for spas and hot tubs. They can heat small bodies of water fast and they’re very compact, so they can be hidden under spa skirts or steps. Energy Saving Strategies The best way to retain your pool’s heat, is to invest in a pool cover. Covers help to keep the water temperature where you want it and double as an additional layer of protection when considering safety options for your pool. They have the added benefits of safety, keeping debris out of the pool, as well as minimizing water evaporation and loss of valuable chemicals. Another way to conserve energy is by turning your heater down or off when the pool is not in use. This may sound like an obvious tip, but many people leave their heaters or heat pumps on because they want a consistent temperature for their pool. If you go a few days without using your pool, it’s a good idea to give the heater, and your wallet, a break. Myth: It’s a myth that it takes more energy to heat a pool back up to a desired temperature than you save by lowering the temperature or turning off a heater. Myth buster provided by energy.gov.
