Free Hot Water Systems

FREE HEAT PUMP HOT WATER SYSTEMS

Free Heat pump hot water systems utilize a refrigeration cycle to draw heat from the air in their surroundings. They channel this heat to a heat exchanger, which then warms water in an insulated storage cylinder. As a result, they usually consume 60 to 75% less electricity than conventional electric hot water systems since the electricity is employed to power the heat pump rather than directly heating the water with an element. These systems are analogous to reverse-cycle air conditioners that heat water instead of the air in your home when operated in heating mode.

BENEFITS OF HEAT PUMP HOT WATER

• By opting for a heat pump, you can expect to see a significant reduction in your hot water expenses, resulting in considerable savings.

• The efficiency of these pumps is noteworthy, as they generate three to five times more renewable energy compared to an electric hot water system.

• Moreover, heat pumps are environmentally friendly, producing significantly fewer greenhouse gas emissions than other heating methods.

• Another advantage is that you don't need any roof space or panels to install them. The installation process is simple and requires the same inputs and connections as an electric hot water system.

WHY IT IS FREE?

Due to the Victorian Government’s various initiatives, like the Victorian Energy Upgrade Program (VEU) and the Small Scale Renewable Energy Scheme; all eligible Victorian residential and commercial properties can enjoy free hot water system upgrades.

INSTALLATION

 The installation process for a hot water supply system in a high rise building is more complex and requires an enormous piping system.

 Several factors need to be taken into consideration, including the type of hot water supply system to be installed and the materials that will be used for the pipes.

MAINTENANCE

 Monitoring temperature of hot water

 Larger scale of circulation in hotel which includes principal loop, subordinate loops, and localized loops (tertiary loops)

 Conducted at sentinel points

 Carried out monthly to ensure hot water is supplied at suitable temperature

THINGS TO CONSIDER BEFORE INSTALLING ASHP WATER

HEATERS

 Before installing the heat pump, an installer should:

 Please verify the location and available space where the heat pump water heating system is to be installed for both homeowners and businesses.

 Make sure that the bearing surface is level and capable of supporting the system's weight. Take into consideration the placement of the exhaust fan and ensure that the circuit breaker and power cable ratings match the recommended current ratings.

 Assess the airflow at the planned installation site and ensure that the heat pump system remains upright during the installation process.

 Consult with the homeowner or business manager about the operational noise level. Finally, review the product manual installation instructions.
