The Bosch Heat Pump hot water tank is also equipped with a 1,650 Watt booster element. This is only called upon in the extreme cold (below 0˚C) and at times of very high hot water demand.

Pick Up From Warehouse - You, your plumber, or your courier can pick the goods up from the above locations. The heat pump can be transported on its side if needed. Please note the packaged unit weighs 128kg and is 2m x 0.7m x 0.7m in size.
Delivery To A Business Address - We can deliver the goods to anywhere in Australia provided it is a business address. Simply choose the 'Delivered To Business Address' option in the drop down menu at the top of this page. This can be your workplace address (if suitable to receive an item on a pallet), your plumber or electrician's business address, or similar.
The Bosch Heat Pump Hot Water Tank is plumbed in like any other hot water tank. Furthermore, because it is so energy efficient, it only needs a 10 amp electrical connection (eg. a regular power point).
There is no requirement to use a Bosch certified installer, but you can search for one here. Most installs cost between $600 & $1,000 (this covers both an electrician and plumber).
The Bosch Heat Pump Hot Water Tank is classified as a solar hot water heater (due to its energy efficiency). The tank can create tradable Small-scale Technology Certificates (STCs) worth up to $1000.
You (or your installer) can claim the rebate by filling out this form. This form is provided by Greenbank, a separate business to Reduction Revolution.
The rebate can be claimed up to 12 months after installation.
Industry leading quality. These heat pumps are designed and made in Bosch's European manufacturing plant in Portugal.
Nation-wide support network. Bosch backs the products they sell with a nation-wide support network. The product comes with a 2 year parts & labour, and 5 year tank warranty.
Ideal for Use with Solar Panels. If you have solar panels, we recommend you set the heat pump to operate during the day (within say 8am to 6pm). This means your heat pump can operate effectively 'for free' from your solar panels. Daytime operation also maximises the efficiency of the heat pump (higher air temperature).
Utilise Cheaper Tariffs. If you don't have solar power, you can still benefit. For example, if you have 'time of use' tariffs we recommend setting the Heat Pump to operate during 'off peak' and 'shoulder' times. This will minimise the cost of running the device.

Adjust the Temperature Set-point. Unlike other hot water systems, you can easily adjust the set-point temperature. The unit is factory set at 56˚C. If you are low hot water users, you can drop this to around 50˚C for maximum efficiency. If you have a large family, setting the temperature higher will increase the amount of usable hot water. Note: the tank is installed with a tempering valve to ensure safety, even at higher set-points.
Weekly Hot Water Sterilisation. For added safety, the tank runs a once-per-week sterilisation. All water in the tank is heated to 60˚C for 30 minutes to eliminate Legionella or other pathogens, in the unlikely event that they are present.
Use 'Holiday Mode' When Away. Yet another unique feature of this hot water tank is its holiday mode. Simply enter the dates when you will be away, and the system will fire-up before you return to ensure a full tank of hot water!

Exact running cost will depend on many factors. These include your usage habits (fittings used, number of people) and your climate. Generally speaking the unit is far cheaper to run than gas or electric systems. If well optimised, it is even cheaper to operate than gas or electric boosted solar hot water systems.
These rough numbers assume a 2-3 person household paying $0.25/kWh. If you live in a warm climate and/or optimise the settings, you can do even better! Like all hot water tanks, the heat pump uses more energy in winter and less in summer.
How is it better than solar hot water?
It can actually be cheaper to run than solar hot water (see above point).
It is much cheaper to buy.
It is less complex, so it is also cheaper to install (no collectors on roof, etc).
It leaves more space on your roof for solar PV panels!
How does it actually perform in very cold weather?
Coefficient of Performance (COP) is the measure of heat pump performance. The average COP for the Bosch Heat Pump is 3.3. This means for each unit of electricity it creates (or rather transfers) 3.3 units of heat.
Other manufacturers often hide their COP performance data. This is typically due to poor performance at low temperatures. Bosch have shared the data with us. As you can see in this PDF even at very low temperatures the COP is still reasonable. For example, at 5˚C air temperature and 15˚C inlet temperature the COP is 3.
Can I run it on off peak 'controlled load' power?
Off peak 'controlled load' tariffs are popular with some electric storage hot water systems. They are not as suitable for heat pump hot water systems as you cannot control exactly when your hot water tank will operate.
Off Peak 1, Controlled Load 1 or Tariff 31. These tariffs are only available for 5-9 hours overnight so we don't recommend them.
Off Peak 2, Controlled Load 2 or Tariff 33. These tariffs are available for 10-18 hours per day so should be okay.
Tariff 62 or Tariff 63 (Tasmania). These tariffs are available for at least 9 hours per day. Owing to the colder climate, we don't recommend them unless you are a small household.
The above 'controlled load' tariffs are not to be confused with 'time of use' or 'smart meter' tariffs. Time of use tariffs vary by time of day and time of week. You can make use of these cheaper rates simply by setting your tank to operate at these times.
Can it be installed indoors (eg. garage, laundry or shed)?
Yes, as long as the room is at least 22.5 cubic metres in size and has airflow to outside.
