Out of all the methods of swimming pool heating, heat pumps are the most economical. In terms of effectiveness, they are up to 700% efficient when compared to electric, gas or oil heating, which at best achieve 98% efficiency.  The following guide will look at the ins and outs of swimming pool, so you can make the right choice when shopping around. The newest generation of swimming pool can harness the free heat in the air in the same way as refrigeration and air conditioning technology. Thus they don’t rely on solar energy – they take the warmth out of the air by compressing a gas which results in an increase in the temperature heating the water as it passes through the exchanger. Some models will even extract free heat from the outside air which has a temperature as low as -15 degrees C.

Most heat pumps can provide up to 5 units of energy to a pool for every 1 unit paid for. Even with the outside temperature at 10 degrees C, they will still deliver 5 free units of energy for every 2 you pay for. Depending on your household’s energy costs, a heat pump can save you up to 80% over propane gas and 50%-70% over natural gas or electrical resistance heaters. Needless to say, this amounts to a massive saving. One of the main benefits of heat pumps over other pool heating methods is that they don’t necessitate complicated gas supply issues, oil tanks or flues as with other heating options.   read more »
