Swimming Pool Heater Installation Tips

Pool heater installation is something that needs to be given a lot of thought before starting. Installing a pool heater can be complicated and very expensive which is why it's essential it's done correctly the first time. An unheated pool will not be comfortable when you first get in it and even after some time it might not be very enjoyable. A swimming pool heater is an essential component which will heat the water inside your pool and make it much more inviting. Heaters are expensive and you must ensure you're choosing the right one.


The most important thing is deciding on where you will be locating the swimming pool heater. If you are installing a gas or propane powered heater for example then it will need to be located close to the fuel source. This might be more flexible with a propane heater since you can decide on the location of the tank.

The heater also needs to be positioned somewhere where you can easily connect the water pipes which pump the water into your pool. This heater will be connected in-between the filter and the return pipe.

Installing the Heater

For the heater to be the most efficient it should be installed on level ground, although it is possible to level and compact soil or any type of ground it's much better to make a level concrete base for this heater to be installed onto. This will provide a stable base which is a welcome addition even though you won't need to bolt the heater down into the concrete.

Solar Heater

If you want to help save the environment and save some money at the same time then you might be interested in installing a solar heater. Solar heaters work by using the energy from the sun to heat the water inside pipes, these are very effective and are a time-tested method of heating pool water. If you live in a sunny location, then these could provide most of the heat required to heat your pool.

Size of Pump

If the heater is being connected to an existing pool then you will already have a pump which circulates water through a filter. The heater will be connected in-between the filter and the plumbing. It's important to ensure that your pump is large enough to circulate the water through the pump. This shouldn't be an issue unless you are installing a solar heater on your roof in which case you will probably need a much more powerful pump to circulate the water.

Size of Heater

When choosing a heater to install you must make sure that it's large enough for your requirements. Find out exactly what you need and how hot you will want to make the water, then purchase the best heater for the job.


When connecting the pump you must ensure that the pump is connected properly and all the joints are sealed. Use plumbers Teflon tape to seal all the joints if you're using compression fittings. You can also use a hacksaw to cut into existing pipes so that the water flow can be directed.

If you're using PVC pipe then use PVC cement instead to provide a strong, cheap and reliable bond between 2 pieces of pipe.
