Keeping Your Pool Warm Without Wasting Money
Let’s cut to the chase—having a pool in New Zealand is great, but if the water’s freezing, you won’t use it much. That’s where pool heating comes in. Whether you want to extend your swimming season or just make your pool more comfortable, the right heating system makes all the difference. So, what’s the best way to heat your pool without blowing your power bill through the roof?
The Main Ways to Heat a Pool
There are a few options, and each one has its pros and cons. Here’s what you need to know:
1. Heat Pumps (Most Popular in NZ)
If you want efficient heating that won’t bankrupt you, a heat pump is probably your best bet. It works like an air conditioning unit but in reverse—pulling heat from the air and using it to warm your pool.
✔ Energy-efficient – Uses only a small amount of electricity
✔ Reliable – Works even when it’s a bit chilly outside
✔ Ideal for long-term heating – Good for those who want to swim from spring to autumn
But here’s the catch: heat pumps take a little while to heat up the pool, so if you’re after instant warmth, this isn’t your best option.

2. Solar Heating (Cheapest to Run)
If you want to keep costs down in the long run, solar heating is worth a look. This system uses solar panels to trap heat from the sun, which is then transferred to your pool water.
✔ Free heating once installed – Sunshine doesn’t cost a cent
✔ Good for eco-conscious homeowners – Reduce your carbon footprint
✔ Low maintenance – No moving parts, just simple plumbing
The downside? It depends on the weather. In winter or on cloudy weeks, your pool won’t get much warmth. But if you live somewhere sunny, it’s a great option.

3. Gas Heating (Best for Quick Heat-Up Time)
Need your pool warm fast? Gas heaters are the speediest way to heat up water, perfect if you like to take the odd winter dip or don’t use your pool consistently.
✔ Heats up the water quickly – No waiting around
✔ Works in any weather – No reliance on sunshine or warm air
✔ Great for spas or occasional heating
But gas prices in NZ can be high, and running a gas heater regularly will cost you. It’s great for on-demand use but not ideal for everyday heating.

Don’t Forget a Pool Cover!
No matter which heating system you go with, a pool cover is non-negotiable. Think about it—what’s the point of heating your pool if all the warmth escapes overnight? A cover keeps heat locked in and cuts down on water evaporation (which also saves money on chemicals).
Some solid options include thermal covers or automatic roller covers. Check out The Cover Company NZ for different types of pool covers that actually work.
What’s the Best Option for NZ Homes?
It all depends on how often you use your pool and how much you want to spend upfront versus ongoing costs:
- Want the most affordable long-term option? Go solar—if you get enough sun.
- Prefer something reliable and efficient? A heat pump is the go-to for most Kiwis.
- Need fast, on-demand heating? Gas is best for quick heat boosts.
And remember—combine any heating system with a pool cover, or you’ll end up wasting energy and money.
Final Thought
A heated pool isn’t just about comfort—it’s about making sure you get the most out of the pool you already have. Pick the right system, grab a good cover, and you’ll be swimming for more months of the year without ridiculous power bills.
