Heat pump popularity has risen greatly here in Perth, Western Australia, over the last several years. As the efficiency of a heat pump means you can heat your pool without very expensive power bills.
They work just like a reverse cycle air-conditioner by extracting ambient heat from the atmosphere, which is then transferred to the pool water. They use a fraction of the energy to generate the same amount of heat, compared to gas. They do work most effectively when you also have a pool cover.
There are a great number of sizes and models, so you are best to get expert advice on the best size for your requirements. Experts will ask for details such as how many months a year you want to swim, what temperature you prefer (most of our customers choose 26-28 degrees), if you have a pool cover, how large the pool is, how much wind exposure there is around the pool area and several other details that will provide you with the best sized unit to suit your needs.
