Electric Water Heaters

Featuring the best electric water heaters in New Zealand

An electric water heater is a device that uses electricity to heat water for domestic use, such as bathing, cooking, and cleaning. It typically consists of an insulated tank that stores the heated water, heating elements that convert electrical energy into heat, and a thermostat to control the water temperature. Electric water heaters are available in various sizes and styles, including tankless models that provide hot water on demand without storing it. They are known for their ease of installation, low maintenance requirements, and consistent hot water supply. Only the best electric water heaters in New Zealand are featured on ArchiPro, an important part of a broader range of hot water heating systems you consider for your home.

Types of electric water heaters

Storage tank water heaters

These are the most common type, consisting of an insulated tank that stores heated water until needed. They are available in various capacities to suit different household sizes and hot water demands.

Tankless water heaters

Also known as on-demand water heaters, these units heat water directly without storing it. When hot water is needed, cold water travels through a pipe into the unit, which is heated by electric elements. They provide a continuous hot water supply and are more energy-efficient as they eliminate standby heat loss.

Heat pump water heaters

These use electricity to move heat from the air or ground to heat the water rather than generating heat directly. They are more energy-efficient and can reduce electricity costs, but they require a larger installation space and work best in moderate to warm climates.

Point-of-use water heaters

These small units are installed near the point of use, such as under a sink or next to a shower. They provide hot water almost instantly and reduce heat loss by eliminating long pipe runs.

Hybrid water heaters

Combining the features of tank and tankless systems, hybrid water heaters have a small storage tank but also heat water on demand. They offer high efficiency and consistent hot water supply.

Solar water heaters with electric backup

These systems use solar energy to heat water and include an electric backup for cloudy days or high demand. They are environmentally friendly and can significantly reduce electricity usage.

How to choose an electric water heater

When choosing an electric water heater, assess your household's hot water needs and determine the required capacity or flow rate. Select the type that fits your requirements, such as storage tank, tankless, heat pump, point-of-use, hybrid, or solar. Look for high energy ratings for efficiency, ensure it fits your space and installation requirements, and compare overall costs. Choose durable models with good warranties and safety features like pressure relief valves and anti-scald technology. Lastly, consider ease of maintenance and professional service availability for long-term reliability.

Ongoing maintenance

Regular maintenance for an electric water heater includes inspecting and cleaning the tank to prevent sediment buildup, checking the pressure relief valve annually, and replacing the anode rod every few years to prevent corrosion. For tankless models, descale regularly to avoid mineral buildup. Periodically test the thermostat and heating elements, and check for leaks or wear in pipes and connections. Schedule an annual professional inspection to identify and fix potential issues, ensuring efficient and safe operation.

Other hot water heater solutions you might need

When selecting your hot water heating system, there are various options to consider beyond electric water heaters. For instance, solar hot water systems are an excellent option for those seeking an environmentally friendly solution to improve their home. Boilers are another great option, known for their quiet operation and minimal repairs. Additionally, gas heaters are a great cost-effective choice since they use natural gas as opposed to electricity.
