Enjoy Your Pool Year-Round: Choosing the Best Solar Pool Heating System for Cold Climates
Living in New Zealand, we’re lucky to have some stunning summers, but that doesn’t mean we want to stop swimming when the cooler months roll in. If you love your pool but struggle with chilly water temperatures during autumn and spring, a good solar pool heating system can be a game-changer. But which one works best for colder climates?
As a homeowner, I’ve done some research to find out what’s available in NZ, what works well in cooler conditions, and where you can get it.
How Does Solar Pool Heating Work?
Solar pool heating systems use the sun’s energy to heat your pool water. The process is simple:
- Water is pumped from your pool to solar collectors (which are usually mounted on the roof or ground).
- The sun heats the water as it passes through the collectors.
- The warm water cycles back into your pool, gradually increasing the temperature.
The effectiveness of solar heating depends on how much sunlight your panels receive, so choosing the right system is key for cooler climates.
What to Look for in a Solar Pool Heating System for Colder Climates
Not all solar pool heaters are designed for colder conditions, so here’s what to keep in mind:
✔ High-Quality Solar Collectors – Look for durable materials that retain heat well, such as polypropylene or high-performance glazed panels. Evacuated tube systems, commonly used for solar hot water, can also work for pools in colder areas.
✔ Large Surface Area – The more exposure to sunlight, the better. Bigger solar collectors will absorb more heat even on cooler days.
✔ Efficient Pumping System – A good circulation system ensures heated water is evenly distributed throughout your pool.
✔ Backup Heating Option – In New Zealand’s colder regions, combining solar heating with a heat pump can be a good solution for maintaining a comfortable temperature year-round.
Best Solar Pool Heating Systems for NZ Homes
After looking into various products, I found that these options are ideal for chilly conditions:
1. Sunlover Solar Pool Heating
Sunlover’s solar pool heating systems are designed to work efficiently in New Zealand’s climate. Their strip solar heating is favoured for its reliability and ability to retain heat. Available through Poolheat, they offer both installation and servicing.
2. Heliocol Solar Heating
Heliocol is another well-known name in the industry. Their solar heating systems come with advanced technology that maximises heat absorption even in less-than-ideal sunlight conditions, making them perfect for NZ’s colder regions. Check out Elite Solar for availability.
3. SmartPool Solar Heating System
This is a popular option among DIY homeowners because it’s relatively easy to install. SmartPool systems use solar panels instead of collector strips, making them more effective at heat retention. They’re available from Bunnings NZ and other hardware stores.
4. Madimack Heat Pumps (as a Hybrid Option)
While not a purely solar system, Madimack heat pumps work well with solar heating for those in colder areas like the South Island. A solar-heat pump combo ensures stable temperatures when solar gain is low. You can find Madimack systems at Ecospring.
Installation Costs & Savings
One of the main attractions of solar pool heating is the low operating cost once installed. While initial installation can cost anywhere from $3,000–$7,000, you’ll save significantly on electricity compared to electric or gas pool heaters.
The return on investment depends on how often you use your pool, but many homeowners find they recoup costs within 3–5 years due to energy savings.
Where to Buy Solar Pool Heating Systems in New Zealand
If you’re considering solar pool heating, here are some trusted retailers:
🔹 Poolheat – Specialists in solar pool heating and pool covers.
🔹 Elite Solar – Exclusive distributor of Heliocol solar heating in NZ.

Final Thoughts
If you want to extend your swimming season—or even swim year-round—solar pool heating is a worthwhile investment. For colder climates like parts of New Zealand, choosing a high-quality, efficient system with good insulation and large solar-collector coverage will make all the difference.
Pairing your solar system with a pool cover can also prevent heat loss and maximise efficiency. And if you really want to ensure a warm pool regardless of the weather, combining solar with a heat pump is a great option.
