Heaters

Spa and pool heaters extract ambient heat from the air outside the unit, and transfer it into the to the pool water stored inside the heater through a heat exchanger system. The external air is drawn into the heater via a fan into an evaporator containing a special type of refrigerant, which is stored in piping. The refrigerant used is called R410a, which isn’t a CFC, so it doesn’t negatively affect the earth’s ozone layer.

The air that has been drawn into the system turns the refrigerant from a liquid into a gas inside the heat pump’s piping. The gaseous refrigerant is then compressed through a series of tubes within the heat pump; a process which generates a great deal of heat. A heat exchanger then transfers the heat from the heated refrigerant gas pipes to a tank where water is stored.

One of the key advantages of heat pumps over solar systems is that they still work in cold or overcast conditions, with some models available to cater for sub-zero temperatures, as well as indoor installations. The other great benefit of this technology is the relatively low running cost. When used in conjunction with a solar blanket, a small heat pump can cost as little as a few dollars per day to run. They are considerably cheaper to run than gas heaters, and don’t require the sun to be shining to generate heat, making them the perfect solution for anyone that wants to use their pool for more than just a few months of the year.

The easiest way to find out the best heating solution for your pool is to get in contact with us. With just a few details about your pool and the way you would like to enjoy it, our customer service team can provide a list of the most suitable systems, and their approximate associated running costs.

Email us at chris@crystalclearpools.co.nz if you would like a sizing recommendation. You can then compare and make an informed decision on how to best heat your pool.

Most people find 28°C to be the ideal swimming pool temperature, but you can experiment and find the temperature that best suits you. Remember, using a pool blanket or thermal cover is the most effective way to retain heat within the pool water. Not using a pool cover will mean that you need to use a bigger and more expensive model heat pump to achieve the same heat.

Depending on where you live, if you want to swim all-year-round you will need one of our larger and more expensive heat pumps. If you are looking for a season extender, then the smaller entry-level products are usually a great option.

Solar, gas and electric heating systems all require a licensed tradesperson for correct installation, and an electrician will always be required to install the larger 3 phase models. In some cases, where suitable electrical outlets already exist near where your heat pump will be installed, the single-phase models may not require an electrician. In any case, you should seek advice from us on (09) 391-0002, or by emailing chris@crystalclearpools.co.nz.
