Spa heater unions are an essential part of your heating system's operation. They connect the heater to the spa pipework, ensuring optimum circulation of the heated water.
These fittings are usually made of PVC or ABS, both of which are corrosion resistant and suitable for use in a wet environment such as a spa. Union fittings are designed to be easy to install and remove, making it easy to maintain and repair the heating system.
Their importance lies in the fact that they ensure a perfect seal between the heater and the pipework, which prevents water leaks and guarantees optimum operation of the heating system. Spa heater unions are available in different sizes to fit all types of spas, both large and small.
