What is a heat pump hot water heater and how do they work? 

Heat pumps use technology to extract and intensify the warmth that is naturally in the air around us then use that warmth to produce hot water. They don’t use solar collectors mounted on the roof like solar systems.

The heat pump consists of an insulated storage tank and a heating module. The heating module must be installed outdoors, but there are options to install the storage tank either outdoors with the heating module, or indoors separated from the heating module by up to 4 meters.

A heat pump works to heat water by transferring the intensified warmth from the air around it into the water, stored in the tank, via a heat exchange system that works in a similar way to an air conditioner.

When emptied, it takes time to reheat to have you back in hot water. Heat pumps draw less electricity than a traditional electric storage water heater, and in doing so, are more energy efficient. They do take longer to heat water, so consider a larger tank capacity to ensure you have enough hot water when you need it.

The Benefits of Heat Pump Hot Water Systems

• Heat pumps are an ideal replacement option for an electric water heater as they will often use existing plumbing.
• Heat pumps are a great alternative to solar where unshaded north-facing or limited roof space is a problem as they don’t require the installation of roof-mounted solar collectors.
• Heat pumps can attract solar rebates and incentives. Ask us for more information.
• Heat pumps consume about 1/3 the electricity of traditional electric water heaters.

Save money and install a heat pump water heater

Heat pump water heaters can reduce the energy you use and greenhouse emissions by up to 65%* depending on where you live, according to Australian Government approved modeling

After installing a new heat pump hot water system, the impact on your electricity bill will depend on the tariffs you pay, and the type of water heater being replaced. The majority of homeowners see the greatest savings on hot water bills when replacing an electric water heater on a continuous tariff.

Heat pump water heaters are recommended for connection to either 24-hour continuous tariff or extended off-peak, minimum 16 hours per day.
