Why You Might Want To Install A Pool HeaterSwimming pools are huge investments as the cost of constructing one for your homeis very high. The payback from this investment is not monetary, rather it isthe enjoyment it generates for the owner and family and friends. However, in manycases the pool is only usable in the warmer months, as it is too cold the rest of thetime, and this limits the return on that big investment. To extend the swimming seasonyou can install a pool heater.Basically what pool heaters do is that they help maintain a constant water temperaturein a swimming pool, to ensure it is always comfortable to use. The recommendedtemperature for a pool is usually set at 78 degrees but other people who prefer toswim in warmer water set their pool heaters to up to 80 degrees or even higher if it isto be used by elderly or very young swimmers.There are three basic types of pool heaters: solar, electric heat pump, and gas/oil.Choosing which type of pool heating system to install in your own pool is animportant decision as there are certain factors to consider like the design of your pool,your usage pattern, the pool’s location, and of course your budget.The most common type is the gas-fired heater which uses natural gas or LPG and isthe least expensive to purchase although can be costly to operate, particularly withLPG.Good examples of gas heaters are: • Jandy Hi-E2 – a top of the range heater with an amazing efficiency rating of 95%. • Raypak Digital Heater - the design enables it to withstand all sorts of weather. • Hayward H Series - easy to install thanks to its low profile, light weight and CPVC plumbing capability.Another type of pool heater is the electric heater pump heater. These are usually moreexpensive to purchase but running costs are low. This is because a heap pump doesnot generate heat it transfers heat from surrounding air to the water. Examplesinclude: • Jandy EE (Air Energy) Heat Pump – models can operate in temperatures as low as 38 degrees. • Raypak Classic Series Heat Pump – features a titanium heat exchanger and come with a five year guarantee. • Hayward HeatPro Range – very quiet operation and can be used to heat both an in-ground pool and a spa.There is also the solar pool heater that uses energy from the sun. Whilst this has thebenefit of free energy it is quite expensive to set up. Additionally, it requires a solarcollection area that is equivalent to the surface area of the pool that will be heated. Italso needs an electric pool pump to bring the water to the solar panels.While a heater is a significant additional investment, it will greatly enhance theusability of your pool by extending your swimming season.
