Electric Swimming Pool Heaters
In many cases, electric swimming pool heaters are the preferred method to heat your pool water. When combined with an Economy 7 supply tariff and solar pool covers, they are a highly effective method. They are slightly more expensive to run than gas heaters, however they are very efficient and are suitable for all types of swimming pools.
The heater will operate at night on Economy 7 at the same time as the filtration period of about 7 hours. The control circuits measure the temperature of the pool water and supplies just the right amount of heat to ensure this is up to the desired temperature the next morning.
Gas Swimming Pool Heaters
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.
Heat exchangers utilise your current heating system in your house to boost the temperature of your pool and can be a cheaper alternative for swimming pool heating.
The swimming pool heat exchanger is plumbed in to both your domestic boiler and your swimming pool pipework allowing the spare heat that has already been produced by your household system to be utilised in heating your swimming pool, cheaply and effectively.
One of the major concerns with any new swimming pool owner are the running costs. The latest generation of swimming pool heat pumps actually harnesses the free heat in the air. In fact the sun doesn't need to shine for the heat pump to work. Based on old technology used in refrigeration and air conditioning, today’s heat pumps take warmth out of the air, by compressing a gas which in turn increases in temperature heating the water as it passes through the exchanger.
Oil heaters have long been used to heat swimming pool water. A few are available that have the pool water flowing directly through them and operate in a manner similar to the gas heater. In the main they are standard domestic or commercial boilers which are connected to the pool water via a heat exchanger.
In this case the oil heater can either be the main house boiler with the heat exchanger added to the system in a manner similar to an additional radiator; or as a stand-alone boiler. In the latter case the boiler will need to be fully installed with either a header tank or expansion vessel and connected to the heat exchanger with a set of primary flow and return pipes.
