Lately, I’ve been doing a ton of conversions, helping homeowners switch their hot water from gas to electric. It’s more than just a trend - it's a massive shift, and I wanted to share why so many people are making the move.
The truth is, the outlook for gas just isn't what it used to be. The local supply is tightening up, and that means we're facing an uncertain future full of unpredictable price jumps and supply worries. For your home's most essential appliance—your hot water system—that uncertainty is a big risk.
Making the move to a highly efficient electric system, especially a hot water heat pump, is simply the smartest way to secure your hot water, your wallet, and your peace of mind for the long run.
This is the number one reason our customers are happy they switched—they start saving money almost immediately.
If you’re on a gas connection, you’re paying fixed gas charges every month, even if you barely use any gas. Switching to all-electric lets you ditch those line or bottle rental fees altogether! Plus, having two separate utility accounts (gas and electricity) limits your choices in the power market. By going all-electric, you open up a wider variety of cheaper power plans and can easily switch providers to get the best deal available.
The star of the show is the hot water heat pump. It uses way less energy than standard electric or gas heaters. It works by stealing heat from the surrounding air (like a fridge in reverse!) and transferring it to your water. This ultra-efficient process means you use significantly less electricity, leading to substantial savings on your power bills over time.
Yes, the initial cost of installing a heat pump can be higher than a basic gas unit, but its incredible efficiency quickly makes up the difference. For a home that uses a lot of hot water, the lower energy consumption delivers major financial benefits that stack up over the system's life, turning it into a fantastic long-term investment.
Beyond the savings, you’re making a great choice for the planet—and for your home’s technology.
Gas is a fossil fuel that releases greenhouse gases when burned. By switching to an electric heat pump, you are running your hot water on New Zealand's increasingly renewable electricity grid. Since much of our power is already clean hydro, wind, and geothermal, your new system will have a much lower carbon footprint than any gas system. It's a simple, direct way to support the country's clean energy goals.
Electric heat pumps are easy to integrate with other smart home tech, especially solar PV panels. You can set up your system with timers to heat your water when your solar panels are generating power or when off-peak electricity rates are lowest. It’s all about giving you more control and cutting your energy bills even further.
Electric systems eliminate the safety risks that come with burning gas and combustion inside or near your home. It’s a cleaner, safer system for the whole family.
If you're facing a replacement, or just tired of the uncertainty and cost of gas, it's time to talk about converting. Give us a call at the shop and let's get you set up with a hot water solution that's reliable, efficient, and future-proof!
But when is gas hot water the best choice?
Gas hot water remains the best choice in specific circumstances where unlimited flow on demand is a priority or where the installation of a highly efficient electric alternative, like a heat pump, is not practical.
One huge plus for gas califonts is how discreet and compact they are—since they heat water instantly and don't require a large cylinder, they take up virtually no space indoors and can be neatly tucked away on an exterior wall, making them ideal for small homes where space is a premium. This means you can finally reclaim that hot water cupboard for extra storage!
Final Word & Next Steps
The overall message is clear: while gas remains the undisputed champion for unlimited hot water on demand and is the most practical choice for homes with tight space or complex electrical needs, the long-term reality points firmly toward electrification. The increasing volatility of gas prices, the diminishing domestic supply, and the superior efficiency and lower running costs of a hot water heat pump make the electric switch the smarter, more financially secure, and environmentally responsible choice for most New Zealand households looking to future-proof their homes and maximise their savings.
