Most Kiwi households don't realise how much their gas water heating actually costs:
| Weekly Cost | What Happens Next | |
|---|---|---|
| LPG | ~$35/week | Keeps going, forever |
| Natural gas | ~$30/week | Keeps going, forever |
| Heat pump (0% finance) | ~$30–$35/week | Drops to ~$6/week once loan is repaid |
Water heating accounts for roughly a third of your household power bill, making it one of the highest-impact areas to cut costs without affecting your lifestyle.
While the upfront cost of a hot water heat pump is higher—starting at around $6k installed—the reduced energy use makes it a cost-effective investment. Over 10 years, switching to a hot water heat pump is estimated to be 27% cheaper than running a traditional electric cylinder, and 21% cheaper than a gas instant system.
That gap only grows as energy prices rise.
Most major New Zealand banks offer green housing finance options at discounted rates specifically to help homeowners switch to energy-efficient systems.
