Heat Pumps

Air Source Heat Pumps

Heat pumps work to efficiently and cost effectively heat homes and water supplies by harnessing free, renewable energy sources. They operate by extracting latent heat from the air in the atmosphere and a compressor is used to generate super-heated gas. The heat of that gas is transferred to the water that gets circulated to the heating (and cooling) distributors.
The air temperature affects the performance of the units, but they can operate in temperatures of -10 degrees Celsius.
At zero degrees Celsius air source heat pumps are approximately 280% efficient. I.e. for 1KW of electricity put into the unit it will generate approximately 2.8KWs of heat output.
 
One system can provide all your home heating, cooling and hot water requirements. Heating capacity of units can vary from 4.5kw to 50kw and select models can accommodate the heating of swimming pools. These systems are economical to run, low maintenance and easily settable with solar power to reduce energy bills. Due to no combustion, there are no flues necessary and therefore, no emission of potentially dangerous gases leading to a low carbon footprint.

Heat pumps are the biggest up and coming product on the hydronics scene. In their own right they’re extremely efficient, yet paired with a solar photovoltaic (PV) system, the energy savings is causing a massive buzz in the industry. We’re thrilled to now be offering package deals with heat pumps and solar PV systems, in partnership with our trusted off grid solar specialist.

Geothermal Heat Pumps

Geothermal heat pumps use the constant temperature of the earth to absorb and dissipate heat (heat exchange). This heat exchange method is used as an alternative to conventional air-based heat exchange methods and operates at such greater efficiency because the ground temperature is steady, whereas Australia’s air temperatures can vary from below zero to in excess of 40 degrees Celsius.
 At zero degrees Celsius geothermal heat pumps are approximately 500% efficient, i.e. for 1KW of electricity put into the unit it will generate approximately 5KWs of heat output.
Studies in USA have found that installing a geothermal heating, cooling and hot water system is the equivalent of planting 750 trees.

Combining Heat Pumps and Solar Panel Heating

A solar photovoltaic (PV) system generates renewable electricity by converting energy from the sun. The solar photovoltaic panels can be connected to the electricity grid and generate electricity that runs electrical appliances in your home. The electricity generated by the PV system is delivered directly to your home for consumption and any excess electricity is exported to the grid.
Solar photovoltaic systems are the perfect renewable partner for heat pumps. PV systems create electricity by using sunlight and then heat pumps can use that electricity to create heating and hot water.
