Water heating using the reverse cycle refrigeration system has been around for a long time but has only become cost effective with the recent energy crises. This system uses the energy that is in the air around us and transfers this energy to heat water. A standard domestic 150 litre geyser has a 3kW electric element to heat the water. The heatpump unit does away with the electric element and will provide 3.5kW of heating but will only use about 1kW of electricity to do this. A heatpump unit can reduce your water heating bill by up to 75%. These units come in various sizes and heating capacities from small 2.8kW domestic units, up to large units of 40kW for large installations such as sports clubs and hotels.
The advantages of this type of water heating are:-
- Works in any type of weather even down to -7ºC
- Does not have to be placed on the roof as with solar systems
- Is reliable and almost maintenance free
- Can run 24/7
- It is energy efficient
- Produces water up to 65ºC
- User friendly controller
- Eco friendly
- Can be retro-fitted to existing hot water systems or designed into new systems.
