A lot like the reverse-cycle air conditioner that heats and cools your home, Heat-pump hot water systems use a refrigeration cycle which uses heat from the surrounding air to heat your domestic hot water. Heat pump hot water systems can use up to 75% less electricity than a conventional electric hot water system.
There are many heat pump hot water systems (HWS) coming into the Australian market with large variances in quality and price. A heat pump HWS report compares each brand allowing householders to make an informed decision on their next hot water system.
An independent heat pump HWS report includes the following:
All-in-one or separated systems– heat pumps are manufactured in two types; all-in-one or separated. The report will explain the advantages and disadvantages of each system.
Cost and savings– estimated purchase and operating costs.
Tank size– recommended tank size to match the number of occupants in your home.
Tank material– tanks are made in stainless steel or vitreous enamel. The report will explain the differences.
Water heating schedule– the most energy efficient time of day to heat water.
Switchboard– switchboard requirements for each heat pump brand.
Water discharge– the process of water heating via heat pumps creates a water discharge from the tank. The report explains drainage requirements.
