Should You Install A Pool Heater? These days looking after the environment is a hot topic and you may be concerned that heating an outdoor pool is not environmentally friendly. It may be seen as a waste of energy and unfriendly to the environment and also very costly. Certainly these points need to be considered but a pool heater can greatly increase your enjoyment of your pool (and the investment in it) by making it useable all day and extending the “swimming season”. There can also be significant health benefits as swimming is very good exercise particularly for people who suffer from arthritis and muscular diseases. A heated pool also prevents chilling and the problems caused by the loss of too much body heat which can affect very young children and the elderly. There are a number of steps you can take to minimize energy usage so that costs are controlled: •
Heater Type - This is probably the key decision. Currently pool heaters powered by gas are the best selling type (such as the Hayward H250 suitable for in ground pools or the Hayward H100 appropriate if you have an above ground pool) but they can be costly to run, particularly if you have to use propane. The up and coming form of pool heating is the use of heat pumps. Normal heaters can never be more than 100% efficient (gas heaters are about 80%) but heat pumps (such as Hayward Heat Pumps) can be several hundred percent efficient (i.e. you get several times more energy out than you put in). This is because they are not actually generating heat they are moving it from one place (the surrounding air) to another (the pool water). Heat pump heaters are not as powerful as gas heaters so need to run for longer periods but they are still much cheaper to run. Pool Temperature - Do not heat the water any more than is necessary for the comfort of users. For most people seventy-eight degrees should be fine. Use a Pool Cover when the pool is not in use - This is essential as a pool cover can reduce heat loss by 50%. It does this by preventing evaporation which is a major cause of cooling. Using a pool cover will also help reduce the amount of chemicals you need to use. Shelter the pool from wind - Wind can cause significant cooling so a pool should be sheltered as far as possible. Proper Maintenance - Make sure the pool and its heating system is properly maintained.
If you follow the points above you will find that a pool heater is a very worthwhile investment.
