Are you looking for an energy-efficient way to heat your pool? If so, you might want to consider using a heat pump pool heater. In mild climates, these devices can be a great option for pool owners who want to save money on their energy bills.
How does a heat pump pool heater work? It uses a small amount of energy to move heat from one location to another. Essentially, it takes heat that is already available and transfers it into the pool water. This process uses less electricity than other heating methods, making it a more cost-effective solution in the long run.
The mechanics of a heat pump pool heater are simple. As the pool water circulates through the pump, it passes through a filter and the heat pump heater. The heat pump has a fan that draws in outside air and directs it over the evaporator coil. The refrigerant within the evaporator coil absorbs the heat from the outside air and becomes a gas. The warm gas passes through the compressor, which increases the heat, creating a very hot gas that then passes through the condenser. The condenser transfers the heat from the hot gas to the cooler pool water circulating through the heater. The heated water then returns to the pool. The hot gas returns to liquid form as it flows through the condenser coil and back to the evaporator, where the whole process begins again.
One of the advantages of using a heat pump pool heater is its higher efficiency, which leads to lower annual operating costs compared to gas pool heaters. Additionally, heat pump pool heaters typically last longer than gas pool heaters, which can lead to even more savings in the long run. When selecting a heat pump pool heater, you should consider its size, efficiency, and costs. A trained pool professional should perform a proper sizing analysis for your specific pool to determine the appropriate size of heater needed.
Heat pump pool heaters are rated by Btu output and horsepower (hp). Standard sizes include 3.5 hp/75,000 Btu, 5 hp/100,000 Btu, and 6 hp/125,000 Btu. To calculate an approximate heater size for an outdoor swimming pool, determine your desired swimming pool temperature and the average temperature for the coldest month of pool use. Subtract the average temperature for the coldest month from the desired pool temperature to determine the temperature rise needed. Calculate the pool surface area in square feet and use the following formula to determine the Btu/hour output requirement of the heater: Pool Area x Temperature Rise x 12. Other factors such as wind exposure, humidity levels, and cool night temperatures also affect the heating load for outdoor pools, meaning that pools located in areas with higher average wind speeds at the pool surface, lower humidity, and cool nights will require a larger heater.
At Rowlen when it comes to efficiency, the energy efficiency of heat pump pool heaters is measured by the coefficient of performance (COP). The higher the COP number, the more efficient the heater is. The federal test procedure for heat pump pool heaters sets the test conditions at 80ºF ambient dry bulb, 63% relative humidity, and 80ºF pool water. COPs usually range from 3.0 to 7.0, which converts to an efficiency of 300%–700%. This means that for every unit of electricity it takes to run the compressor, you get 3–7 units of heat out of the heat pump.
It’s important to estimate the costs and savings of using a heat pump pool heater compared to other heating methods. For an outdoor pool, you can use tables to help estimate your annual heat pump pool heater costs and savings compared to using an electric resistance or a gas pool heater.
Proper installation and maintenance of your heat pump pool heater can optimize its efficiency and extend its lifespan. It’s highly recommended to have a qualified pool professional install the heater, especially the electric hookup, and perform complicated maintenance or repair tasks.
Your heat pump pool heater will need periodic servicing by an air conditioning technician due to its many moving and electrical parts. Ensure to read your owner’s manual for a maintenance schedule and/or recommendations. Generally, you’ll need to tune up your pool heater annually.
In conclusion, a heat pump pool heater is an excellent option for pool owners who want to save money on their energy bills. With its energy efficiency, durability, and low operating costs, a heat pump pool heater can provide a comfortable swimming experience while reducing your environmental impact. By considering the factors mentioned above, you can select the right heat pump pool heater for your pool and enjoy all the benefits it has to offer.
