When it comes to getting the most out of your pool, a heater is a must. There are many fine choices available in the world of electric swimming pool heaters, but you must tread carefully.
The first thing to remember is that swimming pools are big and contain a massive amount of water. If you do not choose a sensible heater you could have a shocking electricity bill in your first quarter of use!
Bearing this in mind, it is always worth thinking about swimming pool solar heaters. These usually need electrical help to pump the water up to the solar panel units and then to work the filter and so on, but they are very effective and cheap to run. Of course some people simply do not have space for, or do not want to have to look at, the panels.
There are still some smart options in electrical pool heating - swimming pool heat pumps, for example have very high efficiencies. They make the best use of the electricity they use and can return very reasonable bills.
Whichever choice you go for you need to get an appropriately sized heater. One way is get an expert to come and look at the pool in situ. We cannot just ring up a dealer and say I have a X gallon (cubic yard) pool, I live in Y and I want to keep it hot, because the location and the type of pool matters. Aboveground swimming pool heaters, for example need to be more powerful that those working with inground units, so buy appropriately!
