How do Heat Pump Hot Water Systems Work?

Heat pump hot water systems are the latest technology in residential hot water heating. They use the air around them to create hot water (using up to 80% less electricity than a standard electric tank) making this technology increasingly popular when considering the choices for replacing an old or leaking electric storage tank.

Heat pump hot water systems work by drawing in the air surrounding the tank. That air becomes the main source of energy, and combined with a very small amount of electricity, generates hot water.

Even in Australia’s often extreme climate, heat pump hot water systems continue to operate very efficiently. Using the air around the tank means that the heat pump works 365 days of the year, whether the sun is out and without the need for solar panels.

Benefits of Heat Pump Hot Water Systems

Reduced Electricity Costs

Savings in electricity costs is now a major consideration for all households. Most Australians currently spend anywhere between $100 - $500 per quarter, depending on a household's usage. By installing a heat pump water heater in your home, you can decrease this expenditure in the long run, as the systems require only a small amount of electricity.

Environmentally Friendly

Heat pumps have been growing in popularity since the government created initiatives to encourage people to move to eco-friendly hot water systems. The reduction in electricity usage also makes heat pump systems an environmentally friendly choice. It uses renewable energy while also reducing greenhouse gas emissions due to its low electricity requirements. As such, replacing your electric hot water heater with a heat pump hot water system is a great way to help reduce your carbon footprint and make your home eco-friendlier.

Heat Pump Hot Water System Replacement & Installation

The team at Inline Plumbing have installed thousands of heat pump hot water systems in our time. We can install the system in as little as two hours, and you could have hot water only a few hours after that.

As heat pump systems are often a straight replacement of an electric tank (albeit with some plumbing and electrical alterations), they don’t take up any more space and don’t require solar panels on the roof. This makes them a favourable choice when compared to solar tanks.
