Hot water is costing you more than you think
Most households are spending more on hot water than they realise - especially those with more people. If you’re using gas, your hot water system could be quietly adding over $1,000 a year to your energy bills. For a family of four or more, those costs really add up.
The smarter solution:
hot water heat pumps
Hot water heat pumps use up to 75% less energy than
conventional gas systems. That means your annual hot water bill could drop from over $1,000 to as little as $200, while still delivering the same steady, reliable hot water.

Why heat pumps are so efficient
Heat pump water heaters don’t generate heat - they move it. This makes them
incredibly efficient. For every one unit of electricity they use, they can produce three to four units of heat. That’s why they’re up to 75% more energy efficient than traditional electric or gas heaters.
Here’s how:
1. Heat is captured from the air – Even in New Zealand’s cooler
conditions, the system draws in warmth from the surrounding air.
2. The temperature is boosted – This warm air is compressed, naturally raising its
heat level.
3. Water is heated – The heat is then transferred to the water via high-efficiency
coils, ready for use.
What heat pumps do we install?
We only install heat pump water heaters that meet the highest standards for efficiency, reliability, and long-term performance. That’s why we work with trusted brands like Primsal and Emerald Energy - leaders in advanced heat pump technology.
These systems are designed to maximise energy savings, perform in a range of conditions, and come backed with some of the longest warranties on the market - so you can count on years of low-cost, reliable hot water.
