Solar Heat Pumps

Solar heat pumps are a convenient way to utilise renewable energy to heat water, without the need for solar panels. Heat Pumps are also effective in reducing your hot water bills as they use approximately a third of the energy of an electric hot water unit.

Traditional Solar Hot Water Systems typically consist of collector panels or tubes which water flows through, connected to a storage tank. Water is then heated by the sun and is pumped or flows between the tank and panel as hot water.

However a Solar Heat Pump (unlike conventional solar HWS) make use of the heat in the ambient air around the system, and a reverse refrigeration process to heat the water.

This means heat pumps DON’T NEED THE SUN to be shine to work, and what’s more, are so efficient that they can provide reliable hot water 24 hours a day, even in temperatures as low as -10°C.

Bosch Heat Pump 270L

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

Its multiple award-winning technology uses the same principle as a refrigerator, but in reverse – extracting heat from the air, transferring it into the water.

Having been developed and manufactured in Europe, the Compress 3000 is well suited to the Australian market as it operates from -7°C to 40°C – ideal for any Australian location. That means you’ll always have hot water, even if it’s below freezing outside.

The Compress 3000 is also highly energy efficient – using 65% less energy than conventional electric storage hot water systems. So the money you’ll save on energy bills makes the Compress 3000 a great long-term investment.

How Do Heat Pumps Work?

Heat Pumps work on a patented refrigeration principle similar to that found in an air conditioner, or refrigerator – but in reverse.

  1. Sun Heats the Air Heat Pumps rely on ambient air temperature rather than incidental sunshine. Utilising refrigeration principles, heat pumps can operate without direct sunshine, and can produce hot water in rain, hail or shine, without the need for a booster element.
  2. Energised Air Inducted into Heat Pump Once the air has been drawn into the heat pump, this passes over the evaporator preheating the refrigeration (that boils at a very low temperature). This preheated refrigerant is then compressed causing its’ temperature to be raised and superheating the refrigerant.
  3. Energy Transferred to Heat Cold Water Using tank wrap technology, this superheated refrigerant is guided through copper tubes (condenser) wrapped around the outside of the tank, turning the whole tank into a heat exchanger which heats the entire volume of water from the outside in.
  4. Cold Air Expelled once the heat has been transferred to the water, the cold air is discharged from the heap pump via a fan, and the refrigerant liquid is forced back into the evaporator to start the process again until the water in the storage tank reaches the desired temperature.
