Why Heating Your Pool is Worth It
Swimming pools are fantastic for summer, but what about the colder months? If you’re like me, you want to make the most of your pool all year round—without breaking the bank on heating costs. Luckily, there are cost-effective ways to keep your pool warm, even here in New Zealand.
Let’s explore some of the best affordable pool-heating options, where to source them locally, and how to get the most out of your investment.
1. Use a Solar Pool Cover
One of the easiest and cheapest ways to retain heat is by using a solar pool cover, also known as a solar blanket.
Why it works
- A solar cover traps heat from the sun, warming the water naturally.
- It reduces evaporation, meaning less heat (and water) escapes overnight.
- It cuts down on chemical use, as it prevents chlorine from breaking down quickly.
Where to buy in New Zealand
You can find good-quality solar pool covers from NZ-based retailers such as:
- Para Rubber – Offers various sizes and thicknesses.
- Splash Direct – Specialises in pool accessories, including covers.
A solar cover is a must-have if you’re looking for an easy, low-cost way to keep your pool warm.
2. Invest in a Heat Pump
Pool heat pumps are one of the most energy-efficient ways to heat your pool. They work like air conditioners but in reverse—using warm air to heat the water.
Why it works
- Compared to traditional electric or gas heaters, a heat pump uses less energy to produce the same amount of warmth.
- They work well in New Zealand’s climate, especially in warmer regions like Auckland, Bay of Plenty, and Northland.

- Waterco NZ – Supplies energy-efficient heat pumps.
- HeatPumps NZ – Offers a range of pool heat pumps with different capacities.
While the upfront investment is higher than some other methods, a heat pump pays for itself over time with energy savings.
3. Solar Pool Heating Systems
If you’re after a sustainable and cost-effective heating option, solar pool heating is worth considering.
Why it works
- Uses solar panels or collectors placed on your roof or ground to heat pool water naturally.
- Once installed, running costs are minimal, as the system harnesses free solar energy.
- Perfect for sunniest parts of NZ, such as Nelson and Hawke’s Bay.
Where to get solar pool heating in NZ
Local providers offering solar pool heating include:
- Future Energy – Offers solar heating systems for pools.
- Eco Pools NZ – Specialises in environmentally friendly pool heating solutions.
Though installation costs are higher, solar heating is virtually free to run, making it one of the best long-term investments for pool owners.
4. Use a Windbreak Around Your Pool
New Zealand’s wind can quickly strip heat from your pool. A windbreak (such as fences, hedges, or glass barriers) helps maintain the warmth by reducing heat loss from wind exposure.
Tips for a good windbreak
- Use glass pool fencing for an unobstructed view while blocking wind.
- Plant thick hedges or install a wooden fence for privacy and warmth.
- Install retractable pool enclosures for year-round insulation.
Many NZ-based pool landscaping companies, such as Designerscapes NZ, offer customised solutions for wind protection.
5. Run Your Pool Heater at Optimal Times
If you’re using an electric heater or heat pump, running it at the right times can reduce energy costs significantly.
Energy-efficient heating tips
- Run your heater during off-peak electricity hours (check with providers like Meridian Energy for low-rate times).
- Use a timer to only heat when necessary.
- Keep the pool covered at night to retain heat.
By being mindful of heating times, you can keep a comfortable swim temperature without wasting energy.
Final Thoughts
Heating a swimming pool doesn’t have to be expensive if you use smart, cost-effective solutions. A solar pool cover is the easiest and cheapest option, while heat pumps and solar heating provide long-term savings. Don’t forget to protect your pool from wind and optimise your heating schedule to make the most of the warmth.
With the right setup, you can enjoy your pool for more of the year—without seeing your power bill skyrocket!
