A Guide to Heating a Swimming Pool Economically

Anyone who has a swimming pool can tell you that heating it can get very expensive, though the costs of running a pool can be reduced dramatically, if the pool is properly designed and managed and sensible options are made in heating methods. Outdoor pools especially can be very expensive, as it can lose three quarters of its energy through surface evaporation of the water. Much as the laundry will dry much faster outside on a windy day, compared to a calm one, the same thing will happen to an exposed pool. A good swimming pool cover can do a lot to eliminate this loss, and can also allow some of the energy from the sun to heat the water, while good design in providing shelter from the wind, to the pool is also very practical in reducing heat loss.

Pool Insulation

Pools should be very well insulated when constructed to avoid heat loss to the ground, with many countries having building standards to ensure this. Naturally, one way to lower the costs is to reduce the amount of heat you are pumping in, especially in periods when you know the pool is not going to be used for a while. Once all options for thermal efficiency have been made, the next big question is what sort of system to actually use to do the heating.

Swimming Pool Heating Options

Without heating, the water in your pool here in New Zealand is unlikely to get much above twenty degrees or so, maybe slightly more on very hot and sunny days. Given that closer to thirty is preferable to most people, this means that even in summer a pool heater in NZ is going to be required. Choosing the most efficient option is obviously going to save you money when the heating bill arrives. Sunlight provides a certain amount of heat to your pool naturally, so a solar option would appear to be quite attractive, given it is energy efficient, as well as being environmentally friendly. A good solar water heater is not cheap and are really better off being used for residential heating purposes, with probably the biggest disadvantage for a pool being, that they need sunlight in which to function, so on cloudy and overcast days, those being when you need the heat the most, they are not functioning particularly well.

Solar Power

A solar system can help, but really needs to be backed up with an additional heating method. Gas powered or fuel heating systems are an option, although they are not particularly energy efficient. Heat pumps are an excellent addition or alternative to relying on solar, and are extremely efficient, cheap to run, simple to operate and long lasting. A heat pump uses electricity to extract heat from the air and pump it into the water and are can produce five kilowatts of heat for only a single kilowatt of energy, a fraction of the cost of gas or fuel.

So, if you want to use your pool as much as possible, but have it cost you only about the same amount as a cup of coffee per day, when combined with a cover to keep the warmth in, a heat pump really is the best option.
