The Bosch Compress 3000 air-to-water heat pump represents the very pinnacle of energy efficient water heating innovation.

The heat pump is essentially a refrigerator in reverse. A refrigerator creates and distributes cool air, while expelling the waste heat into the atmosphere.

A heat pump works in the opposite manner, by creating and distributing heat into the stored water and expelling cooled air into the atmosphere around it.

Using 65% less energy than conventional electric storage hot water systems, the Compress 3000 is a highly efficient device that transfers excess solar energy into thermal energy in the form of hot water.

As the heat pump only requires 0.6 kW of input compared to a conventional system that requires 3.6 kW, the energy requirements can be more than covered by a domestic solar system. So the money you’ll save on energy bills makes the Compress 3000 a great long-term investment.

Features & benefits:

  • Highly efficient heat pump – reduces energy consumption by up to 65%*
  • Eligible for generous government rebates
  • 270L storage tank
  • Built in smart controller with timer function and compatibility with PV Solar energy generation systems
  • Noise reduction mode
  • Designed for easy and low-cost install and servicing
  • The heat pump operates from -7ºC to 40ºC, delivering energy efficient hot water even in colder climates

We paid a visit to the lovely Sylvia whose Hot Water System stopped working.

She was in a panic without Hot Water. It was great to assist her with this dilemma.

 

Note: Heat pumps use the ambient temperature in surrounding air to heat water in the tank. This means as the air temperature around the tank decreases, the time taken to heat the full tank increases. Customers in colder climates
and frost prone areas should consider this when deciding which type of Bosch system is best for their circumstances.

*When compared to conventional electric storage system.

Currently, this system is only available to be installed by Sunlife energy only.

What is a hot water heat pump?

A heat pump hot water system is a type of solar hot water system but without panels needed on the roof. The unit utilises a refrigerant to absorb heat from the air and transfer this heat to create hot water. A heat pump works in a similar way to a refrigerator but in reverse.

Why choose a heat pump over a solar panel hot water system?

The running costs for a heat pump can be around the same or in some instances less than a solar panel system. A hot water heat pump is cheaper to install as there is no need to put the panels on the roof. If your roof is not facing the correct way or is obstructed by a tree, then a heat pump is the best option. Heat pumps work well in conjunction to PV systems as they don’t compete for roof space, draw low amounts of energy (Max 700W) that would usually be fed back to the grid.

What is the warranty on the hot water heat pumps?

5 Years on the Tank. (Part only)

2 Years on the Parts and Labour.

Will the hot water heat pump provide me with enough hot water?

The unit is suitable for 3-4 people living in the house. The Bosch hot water heat pump can deliver 335 litres of 40’c of shower temperature water on one single draw when the appliance is set to 56oC.

How noisy is the hot water heat pump?

The hot water heat pump sound that is heard is from the compressor and the fan which is 43dB as measured from 2meters away. Plus, the unit has a noise reduction mode to assist if needed.

Will the hot water heat pump work with solar PV systems?

Yes, the heat pump has been designed to work in conjunction with PV solar systems. The heat pump can be programmed to run during the hours of the day when PV generated energy is available, using the excess energy.

The heat pump can also be set up to have a direct communication link to compatible inverters that are designed to work with ‘smart grid ready’ appliances. The heat pump can receive a communication signal from the inverter or energy management system telling the appliance that excess energy is available. If the water held inside the heat pump requires further heating, the heat pump will then run until the appliance is fully heated.

How much of a household’s energy is used for water heating?

In Australia, on average around 40%of a household’s energy is used on heating hot water. Installing a Bosch heat pump with a PV system will allow the owner to reduce their energy use considerably, and give a good increase on self-consumption of PV generated energy.

How much power does the heat pump draw?

Under normal operation the heat pump will draw up to 600W (2.6 amps) and 2.25kW (9.8 amps) when the back-up element is activated. The back-up element is only activated in very cold ambient air temperatures (usually only below an ambient temperature od 0oC).

Can the hot water heat pump be installed indoors?

Yes, as long as the Shed/Carport is 22.5m3 clear space with airflow from outside.

If the air temperature is 0oC will the heat pump still produce hot water?

Yes, the heat pump has an element in the unit 1.6kw element, the heat pump operates from -7oC to 40oC delivering energy efficient hot water.

Eligible for the government rebates STCs (small scale technology certificates) and VEECs (Victorian Energy Efficiency Target Certificates)?

Yes, they could get STCs for any new installation.

STCs

Zone 1 – 23 STCs

Zone 2 – 23 STCs

Zone 3 – 27 STCs

Zone 4 – 29 STCs

Zone 5 – 27 STCs

If replacing an electric storage water heater in VIC they are eligible for both STCs and VEECs.

How efficient is the heat pump compared to a standard electric unit?

The Bosch hot water heat pump reduces energy use by up to 65% compared to a conventional electric storage hot water heat pump, in Zone 3.

Can the hot water heat pup be transported lying down on its side?

Yes, the unit can be transported lying down on its side but before turning it on it needs to be sitting up right for at least 30mins.

What is the weight of the hot water heat pump?

The weight of the unit empty is 130kg.

What is the height and width of the unit?

Height – 1840mm

Width – 670mm

What is the refrigeration used in the compressor?
