Best Swimming Pool Heaters Buying Guide
Before choosing the best swimming pool heaters you should consider the following options:
1. Energy Efficient Pool Heaters: One of the most important things to consider when choosing a swimming pool heater is energy efficiency.
The Department of Energy estimates that more than 25 percent of the energy used in a typical pool is lost through dissipation.
This can be reduced by choosing a more energy-efficient option, such as a heat pump.
Heat pumps move heat from one place to another, typically from the environment to the pool, using a fan and a heat exchange system.
They are more efficient than other types of heaters, reducing energy consumption by up to 75 percent and potentially cutting your energy bills by up to 30 percent.
2. Pool Volume: The size of your pool will also affect what type of pool heater you should choose.
Heat pump heaters are best for pools measuring up to 50,000 gallons. Above that size, you may need to look at other options.
Gas pool heaters, for example, are best for pools with a volume of 20,000 gallons or less. If your pool is larger, you will likely need two heaters to ensure the water is heated evenly.
3. Pool Shape and Location: The shape of your pool will also impact your choice of heater. If your pool has a very shallow end, for example, you may want to consider a heat pump, which is best suited to shallow pools.
You will also need to consider your climate. In cold climates, heat pumps are the most energy efficient option, while in milder climates, it is possible to use heat pumps all year round.
Other factors to consider include how efficiently heat is absorbed into the water, which depends on factors such as the depth and temperature of the water.
If your pool is in a shaded area, you will also need to look at heaters with a larger capacity to ensure the pool is heated evenly.
4. Pool Use: The type of pool heater you choose will also depend on how you plan to use your pool. If you plan to use it for swimming, for example, heat pump heaters are the most efficient option.
If you plan to use your pool for parties and entertaining, you may want to look at heaters that have a faster recovery rate.
What else you should know about best swimming pool heaters
1. What are the different types of swimming pool heaters?
There are three main types of swimming pool heaters: gas, electric, and solar.
2. How do I size a swimming pool heater for my pool?
A good rule of thumb is to select a heater that is able to raise the temperature of your pool by 20 degrees Fahrenheit in 8 hours or less.
3. How do I install a swimming pool heater?
There is no one-size-fits-all answer to this question, as the installation process for a swimming pool heater can vary depending on the type and model of heater you have. However, in general, you will need to connect the heater to the pool’s filtration system and then to a power source. You may also need to install a gas line if your heater runs on natural gas.
4. How do I maintain my swimming pool heater?
Swimming pool heaters require regular maintenance to function properly. The most important thing to do is to keep the filter clean. The filter keeps the water clean and free of debris. It also helps to circulate the water.
