Solar Pool Heating Systems

Solar Pool Heating Solutions

While there are different types of ” solar pool heaters ” all make use of sunlight. Special sunlight collectors capture the sunlight and use it as a source of energy for the heating process of the pool. No matter how large your pool is, there is a right solution for all sizes. Mobile and fixed models are also available. This means that the mobile version can easily be placed anywhere and stored away, for example, in winter. Fixed solar heating is particularly suitable for very large swimming pools, which are also used during winter months.

Heating your pool with solar heating allows you and your family to enjoy a cost-effective and environmentally friendly warm pool that is inviting even during the winter months. When the temperature outside plummets during winter, solar heating will continue to warm your pool to summer levels.

Choosing to heat your pool with a solar heating system is a great way to experience the luxury of a heated pool year round. Solar pool heating systems use free energy from the sun and require very little maintenance compared to the annual maintenance needed for conventional pool heaters.

Solar pool heating is a smart investment. Although people can be put off when faced with the initial outlay that a solar pool heating system can require – you can rest easy knowing that a solar pool heating provides a payback of between 2 and 7 years. After this time, you can sit back and enjoy another 10-20 years of free heating from the sun. So what do you need to consider when looking at a solar pool heating system?

In order to get the best out of a solar pool heating system a number of factors will need to be weighed up. Basically though, as long as your swimming pool is facing north and it is not in direct sunlight you will benefit from a solar pool heating system.
Pool Heating NZ can provide you with the information you need about your pool site and how factors like solar resource, climate, local building code requirements, and safety issues will affect your site.

The benefits that a solar pool heating system can provide you and your family are worth contemplating. As the renewable energy from the sun heats your pool, no further energy is needed to power the system. Unlike other forms of heating, solar automatically operates whenever the sun is shining and your regular pool pump is running.  This means that your pool stays warm throughout the season and is ready when you are. A solar pool heating system is almost maintenance free. If looking after the environment is important to you or your family, then installing a solar heating system allows you to reduce your carbon footprint and there is absolutely no air pollution from a solar system.

Pool Heating NZ can offer a number of options for your pool. In general, there are three types of solar pool heating systems:

Evacuated Tube collectors

An evacuated tube system has excellent all year round performance. Not only that, but, they are very cost effective and have been one of the most popular forms of solar collectors for over 20 years.

Pool Heating NZ supply systems that are created using German technology but are specifically designed to suit New Zealand conditions. Even when the weather is inclement, our evacuated tubes will collect energy and heat your water. Instead of having high heat loss when the temperature drops or the winds pick up outside, our systems ensure your water is always well insulated. There is low conductive and convective heat loss. A multifunctional controller automatically manages the temperatures on the roof and in your cylinders to give you comfort and peace of mind.

An evacuated tube system from Pool Heating NZ will:

  • Work well in colder climates
  • Gain heat in both cloudyor sunny days
  • Has easy installation
  • Is cost effective
  • Can attach to existing cylinders
  • Has the best all year round performance

Flat Plate Collectors

Flat Plate Collector systemshave multiple performances. They are responsible for solar energy absorption, conversion to thermal energy and then heating water.

Pool Heating NZ ensure that all Flat Plate Collector systems receive thorough testing – both through hydrostatic tests and quality inspections. Our systems have exclusive technology that allows a higher heat absorption by the plate than other systems available in the market.

Our systems are innovative and are all approved with international quality standards. They are rated to cope with New Zealand’s winter temperatures and have total protection against water freezing inside the collector. They have a longer life span than other types of systems as they have a patented “Vent-Plug” ventilation system that avoids water condensation inside the box. This also helps to improve the efficiency of the collector.

A Flat Plate system from Pool Heating NZ will:


  • Provide better efficiency than plastic due to glazing
  • Looks like a skylight so is aesthetically pleasing
  • Limited maximum temperature
  • Works really well for pools

Poly Systems 

Poly Systems have been available in the solar power market since 1981. Pool Heating NZ can offer you solar technology that features the most advanced and structurally solid solar collection panels available. These are otherwise referred to as a Polycrystalline System. They have a slow and lower temperature system whilst other panels are higher temp and faster but you will require a heat exchanger.

APoly Tube system from Pool Heating NZ will: 

  • Produce more energy, last longer and are better suited for New Zealand’s climate.
  • Can be anchored into trusses. This eliminates loose or pulled out connections and roof leaks.
  • Has a no-roof-leak guarantee.
  • Use a patented, permanent connection instead of rubber hoses, there is no maintenance needed on the system.

No matter which solar pool heating system is the right one for your situation, you will find that your system will include a solar collector, a filter, a pump, and a flow control valve. Both systems pump the pool water through the filter and then through the solar collector, where it is heated and then returned to the pool.

If you are worried about how difficult a solar pool heating system might be to use. Relax. All you need to do is click the switch to “Auto” at the beginning of your pool season and set it to the desired temperature. Jump into your pool and enjoy!

At the end of the season, click the control switch to “Off”

It is recommended you check your pool temperature and solar controller at the beginning of the solar pool season (typically October or November).

After installation, properly maintaining your system will keep it running smoothly for 10–20 years. Pool Heating NZ can advise you on the appropriate maintenance schedule for your selected system Your collector should require little maintenance if the pool’s chemical balance and filtering system are checked regularly.
