Solar heating for Swimming Pools

With costs escalating, the prospect of heating your swimming pool using the energy of the sun is a more than exciting prospect. With the correct equipment, this can be achieved saving you hundreds of pounds heating your swimming pool every year.

For optimal performance, you may wish to use solar pool heating in conjunction with other methods of heating the pool water due to the unpredictable seasonal weather. If solar heating is used as a secondary source it will still save you money on your heating costs.

There are various designs of panels which ultimately work in different ways. In the main, the premium solar panel systems are controlled by a different controller which is set to measure the temperature of the water and the temperature of the air. When the air is sufficiently warmer than the water of the pool the system starts, otherwise the heat from the pool would radiate the air and consequently the cooler air could reduce the temperature of the pool.

Some of the cheaper systems which are used mainly on above-ground pools do not have this option so it is important to test this yourself manually before switching on the system.

Swimming Pool Heat Pumps

One of the main advantages of swimming pool heat pumps over other pool heating systems is that they require no complicated gas supply, oil tanks or flues and in the main will operate from small capacity electrical supplies.

In addition, the average pool owner doesn’t want the trouble of constantly monitoring the heating so most systems are fully automatic and need only one control – the pool water thermostat.

Being easy to install, quiet in operation and their reliability swimming pool heat pumps are a popular choice. Ideal for the domestic environment.

Based on old technology used in refrigeration and air conditioning swimming pool heat pumps take the warmth out of the air, by compressing a gas which in turn increases in temperature heating the water as it passes through the exchanger. Most heat pumps can provide up to 5 units of energy to the pool for every 1 unit paid for.

Electric heating for a pool Swimming Pool Heater

Electric Swimming Pool Heaters are in many cases the preferred method to heat your pool water. You can improve the costs of operating your electric swimming pool heater by combining the operation of the electric heater with an economy 7 supply tariff and possibly the introduction of solar panels, making the most of those warm summer days. Electric swimming pool heaters are a very effective and efficient way of heating your pool and when combined with the right pool cover you can make further energy savings.

Gas Swimming Pool Heaters

The most common type of heater and the most economical is the gas pool heater. Gas Pool Heaters (otherwise known as Gas Boilers) are a great way to heat your swimming pool all year round and are available for indoor and outdoor pools.

These types 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 positioning of the heater the heaters positioning is important and again must be 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 co*ck 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-inbuilt in safety devices to protect yourself and the equipment from various elements. Firstly is a high-limit 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.

Pool oil heaters

Oil boilers have long been used to heat swimming pool water but nowadays are less common in residential applications, none the less they are still a very efficient method of heating your swimming pool.

They are fundamentally designed identically to gas-fuelled units, except they burn oil instead of gas. Some oil-fired oil fired pool heaters have the pool water flowing directly through them, in others cases, cases a domestic oil heater is used in conjunction with a swimming pool heat exchanger.

As with a gas boiler, the flue and ventilation requirements are critical. Care must be taken when sighting the boiler to ensure that flues do not terminate close to windows, to boundaries etc. Additionally, these stand-alone stand alone pool boilers will require a connection to an oil supply whether existing or a dedicated tank.

Swimming Pool Heat Exchanger

Standalone Heat Exchangers are a very effective and economical method of heating your swimming pool. Providing your domestic household energy source is sufficient, they utilise this heating system to transfer the heat to your pool water when not required by the house.

The heat exchanger has an outer shell that contains a multitude of small-bore tubes. The hot water from the house boiler circulates between the heater shell and the tubes; the pool water flows through the tubes and is heated by them. The two waters do not mix. The water from the house heating comes through pipes, which are connected to the heat exchanger and the pool water thermostat controls the pool temperature.
