As we look towards the future, it’s becoming increasingly clear that electric hot water heating is the way forward. With growing concerns over the environmental impact of traditional fossil fuel-based systems, as well as the need for more efficient and cost-effective solutions, electric hot water heaters are emerging as the preferred choice for homeowners and businesses alike.
One of the primary advantages of electric hot water heaters is their energy efficiency. Modern electric models are designed to maximise heat transfer, minimising energy waste and resulting in lower utility bills for the user. Additionally, with the ongoing shift towards renewable energy sources like solar and wind power, the carbon footprint of electric hot water heaters is continuously decreasing, making them a more sustainable option.
Will an electric hot water heater cost me more?
One of the biggest concerns of homeowners is the initial outlay to install an electric hot water heater combined with the cost of closing off and replacing gas systems. Most modern electric systems do have a higher up-front cost.
However, the ongoing savings from installing a more efficient hot water heating system are often overlooked. Hot water heat pumps typically use 60 to 75% less electricity than conventional electric hot water systems, while providing the same temperature and volume of heated water. For those replacing a gas system, the savings are even more significant and the benefits to the environment are hard to ignore.
Gas connections are setting homeowners up for rising prices. According to a report for the gas industry, gas prices could increase by 20-40% by 2035 under four different scenarios. While electricity prices are also expected to rise in the short-term, they are projected to decline as renewable electricity generation grows.
Is electric better for the environment?
New Zealand generates and consumes around 43,500 gigawatt hours (GWh) of electricity a year. Most of our electricity comes from renewable sources such as hydroelectricity, with the overall share of renewable electricity generation exceeding 80% in most years.
In 2022 the total electricity generated included contributions from the following sources.
- 60% hydroelectric generation, the majority of it is found in the South Island.
- 18% geothermal generation, most of it situated in the Taupo Volcanic Zone.
- 6.5% wind generation, most of it situated in the North Island.
Although generating electricity sometimes involves burning gas and coal, it heats the planet significantly less than burning gas directly. That’s partly because of the greater efficiency of heat pumps and other electric appliances, and partly because the grid is mainly run on renewable power, and the mix is getting cleaner over time.
Installing an electric hot water heat pump
Replacing an existing hot water system inside you home is often not complicated with Apricus Eco’s range of Hot Water Heat Pumps. Two of the systems offer outdoor cylinder installation which make them the perfect option for gas hot water replacement where there is no room for an indoor cylinder.
Electric hot water heaters are known for their reliability and longevity. With fewer moving parts and reduced maintenance requirements compared to traditional gas-powered systems, these electric models provide a hassle-free and low-maintenance solution for hot water heating.
As the world moves towards a more sustainable future, the advantages of electric hot water heating become increasingly evident. With their energy efficiency, environmental friendliness, and overall reliability, it’s clear that the future is electric for hot water heating.
