Some of your FAQs...
What is a hot water heat pump?
A Heat Pump Hot Water System uses leading technology to draw energy in from the ambient atmosphere and transfer it into heat. Ozone friendly refrigerant (CO2) absorbs the heat, which then flows into a compressor, where it’s converted into a high temperature gas. It then passes through a condenser within the water heat exchanger and the water is heated and then stored in the hot water tank for later use. No backup booster is required.
What is required to install a hot water heat pump?
Much the same as a conventional hot water system, Heat Pump Hot Water Systems are easy to install and many feature flexible tank configurations in both stainless steel and glass lined options. The CO2 Heat Pump and either Stainless Steel or Glass Lined Enamel storage tanks can generally be located up to 10 metres apart horizontally, or 5 metres vertically. Installation requires a licensed plumber and an electrician, which are provided by Specialized Solar & Electrical.
My home is in an alpine region. Will a heat pump work in sub-zero conditions?
Yes. In countries such as Germany, or those in Scandinavia, whole towns have long been heated with giant industrial heat pumps. Norway was just recently announced as having the highest penetration of heat pumps in the world, with six out of ten households having heat pumps installed.
The Reclaim Energy CO2, and Apricus Heat Pump Hot Water Systems will operate effectively between -10ºC and 43ºC, and -7ºC to 42ºC respectively, without the need for an electric backup/booster element. The Reclaim is also fitted with inbuilt freeze protection, making it suitable for all Australian conditions and climate variations.

What size system SHOULD i INSTALL?
A 160 litre tank on your system will typically service a two person household, ranging up to a 400 litre tank which will normally service a five person household. Our installer will help you make the right decision by reviewing:
- Your geographic location
- How many people live your household
- Your household water demands
- The water quality in your area
Can i combine my hot water heat pump with my solar system?
Combining the system with your PV system (Solar Power System) only enhances the reduction in energy consumption and costs. The average electric element hot water system has an energy input of 15 kWh for 315 L of hot water delivery. However a heat pump system of the same size has an average of 3 kWh electric input. The systems installed through Goulburn Murray Solar Savers are designed to consume excess PV during peak sun hours to maximise savings and take advantage of the energy already created rather than exporting it back to the grid. Therefore this is like having a virtual battery for your home.
Most systems also come with Smart Controllers to allow the customisation of how and when the hot water system works.

What sort of savings will a hot water heat pump give me?
A heat-pump hot water system uses much less electricity than an electric storage hot water system. This is because it only uses electricity to drive the compressor and the fan, instead of using electricity to heat the water directly with an electric element. As an example, a standard electric hot water system will use 3.6 kW of electrical input to deliver 3.6 kW of thermal output. A heat pump will use 1 kW of electrical input to deliver 5 kW of thermal output. Typically hot water heat pumps use only 20% of the energy required by an electric storage hot water system, saving up to 80% compared to conventional electric hot water energy costs.
do hot water heat pumps come in commercial sizes?
Absolutely. It depends what size and type of commercial application as to the hot water heat pump you could consider, ie a restaurant or cafe will have different needs compared to an aged care residence or a hotel. However there are extremely efficient and sophisticated systems ranging from 3000 litres to 15,000 litres per day which offer considerable financial operational savings. The excellent environmental benefits also mean access to rebates including VEEC, STCs, VEUs and federal tax benefits.
what is the noise level of a heat pump?
The CO2 Heat Pump for the Reclaim model is rated at 37dB, measured at 1m distance from the unit, which is whisper quiet, practically silent. LISTEN NOW >
Quality assurance and verification is based on Japanese Industrial JIS C 9220 standard testing and performance for heat pump hot water heaters. Variances outside this rating may occur due to background noise, measurement conditions and accuracy of device used. Installation location, mounting legs and clearance positioning may also affect noise level.

i have bore water - will i be able to install a hot water heat pump?
Glass lined tanks are typically used in places where the water has a high mineral content, or for bore water. If your water isn’t particularly high in mineral content, then you’re better off with a stainless steel tank. A stainless steel tank will require less maintenance, as it doesn't require the sacrificial anode that glass-lined tanks do.
are there any rebates for hot water heat pumps?
Yes. Goulburn Murray Solar Savers has more detailed information about what's available on our Rebates & Savings page.
what are veec's and stc's?
VEECs are Victorian Energy Efficiency Certificates that represent the amount of carbon dioxide equivalent (CO2-e) in tonnes that would be displaced by the use of the installation. The rebate is taken off the price of your system by your installer.
Australian Government Small-scale Technology Certificates represent the amount of electricity in megawatt hours (MWh) that would be displaced by the use of the solar water heater over its lifetime of up to 10 years. One STC is equivalent to one MWh of electricity offset by the solar water heater. The rebate is taken off the price of your system by your installer.
