How to Install a Pool Water Heater?

It is highly recommended that you hire a professional to do the installation for you. There are numerous variables that come in play for installing a pool water heater and a lot of times people have a bigger loss by spending time in installing it themselves instead of paying a professional to get it done in few hours. But if you end up deciding that you can do the installion yourself, below are steps that will help you do it correctly. Pool owners who want to extend the swimming season even after the onset of winter should install a pool heater. These increase the temperature of the water in the pool, thus making it possible to swim in the colder months of the year. Water passes into the heater through the filter and is warmed in its combustion chamber. It is then passed back into the pool, allowing you to swim in comfortably warm water.

Step 1: Buy a swimming pool water heater.
We understand that this is an obvious thing to say, but when we say buy a swimming pool water heater, we mean buy a system that will fit your need and can be installed in your house. Pool heaters come in a variety of sizes that determine their cost. Purchase one according to the size of your pool.

Step 2: Select a location where you would want to install the system.

This is very crucial as the location will define how big of a job it will be for you to install the swimming pool heater. When selecting an appropriate location for your heater, keep in mind the clearance distances above the unit and to its sides, to enable it to operate safely. This is where the first step of installation comes in. The distances will depend on the size and model of your heater and will be mentioned in the manufacturers instructions. You should also keep it as close to the filter as possible to avoid extra piping. We suggest that you should try to install it around two to five feet from the filter.

Step 3: Connect the water line into the filter.
You will need to turn your filter off before you start the installation. Begin plumbing the heater by measuring the distance from the return valve of the filter to the inlet valve of the heater. This is the location where you would cut and attach a PVC pipe. This will be used to get the water into the heater system.

Step 4: Channel the warm water into the pool.

Measure and cut another piece of PVC pipe and run it from the outlet valve of the heater to the water inlet of the swimming pool. This will take warm water into the pool. Use a plumbing compound to tightly secure the pipes and joints.  Make sure there is no leaq in the joints as it will lead to losing of heat energy as well as the water.

Step 5: Connect the fuel supply line and the electric power cable.
Now this depends on the type of connection you would be doing. In case of a gas water heater, you connect the gas line to system. But before you do that, you will have to make sure with your city officials with regards to weather or not you are allowed to do that yourself. Some cities send out officials to do the connection. If you have an electric water heater, you would be just connecting the system to an electric outlet that could be used.  After connecting to a fuel line, connect the 120-volt plug of your heater to an electric outlet. Install a covering over your outlet to protect it from the weather and plug the heater in.

Step 6: Test the system
Make sure the system has no leaqs or issues by using the system on a test drive. After your installation and setup is complete, you should test the unit to make necessary amendments. Turn the pool filter back on. Then turn the heater on and raise the temperature on the thermostat slightly. A fan will blow before the heater ignites. Check that the heater has a blue flame. The temperature in the pool will rise shortly after you turn the heater on. Most heaters have flow sensors that detect water pressure and disable it from turning on if the water drops to a certain level. Keep the power off when the pool is not in use to avoid accidents.
