About Swimming pool Gas boilers

The most common type of heater and probably one of the most economical is the Gas Heater (those that use natural or propane gas as the heating fuel). Gas Pool Heaters (otherwise known as Gas Boilers) are a great way to heat your pool all year round and are available for indoor and outdoor pools.

These type of heaters must be installed by a registered gas engineer in accordance with the appropriate regulations. These include the size and position of the flue, the gas supply and ventilation. Some gas heaters are designed to stand outside a building in the open air and in this case there is no flue but the heaters positioning is important and again must in accordance with regulations.

In general there are three separate switches which control the heater. Firstly is the on/off switch on the heater itself. Secondly is the thermostat, which will allow you to set your desired temperature of the water and finally a gas cock on the gas supply. This is a small valve which will allow you to open or shut off the gas supply to your heater. The heater also has three built in safety devices to protect yourself and the equipment from various elements. Firstly is a high limit thermostat, which will shut down the heater if it gets too hot and consequently switch the heater back on when it has cooled down. A safety gas valve, which will cut off the gas supply if the flame or pilot light goes out and a pressure switch which will turn the heater off if the pool water stops flowing and back on once flow has resumed.
