Why Solar Heat Pump Heater

Solar hot water comes in two forms, but both methods use the heat of the sun’s rays to give you the hot water you need for bathing, washing the dishes and washing your laundry in warm water.  The most widely used method consists of a set of pipes (usually in a sort of black glassy panel) that is installed on a north-facing roof as close as possible to your hot water tank.  This method often also uses evacuated tubes to help the water in the pipe heat up and to stay hot via insulation.  Sometimes, these solar hot water systems have a gas/electricity-boost, which means that even on the cloudiest, coldest day of a Melbourne winter, you will have all the hot water you need.
The second method uses heat pump technology. 

The heat pump will take the heat out of your house (where you don’t want it) or elsewhere, and will transfer it into the water.  And as the excess heat in your house or in the atmosphere is heated by the sun, this is indeed a form of solar hot water.
Where it is not possible to drill in a ground probe or install a surface ground loop on the property, an air source heat pump may well be the answer. The only space requirement is an outside wall making them ideal for apartments and homes with limited outside space.With no need for groundworks, installation costs are kept to a minimum.
