.: Heat Pumps
How Does It Work ?
Heat pumps heat your water by extracting the heat out of the surrounding air and transferring it to the water that flows through the device. A circulation pump, circulates the water from your geyser through the domestic heat pump, where an exchange of heat takes place.
How Does It Save Me Money ?
Where your normal geyser takes 4kw of electricity to generate 4kw of heat (a COP of 1), a high quality heat pump use only 1kw to generate 4kw of heat (a COP of 4). More technical info can be viewed by clicking here
Sizes and Rebates
(COP = 4)
A 4.7kw heat pump can heat up to 500 litres of water. A normal electrical element will have used around 20kw to accomplish this feat, but the heat pump, depending on the ambient temperature, will only have used around 5kw. Saving you around 75% of your water heating cost !
3.0kw (COP = 4)
A 3.0kw heat pump is capabale of heating up to 300 litres of water using only around 3.0kw versus the 12kw a normal electrical element would have used !
When you install an Accredited Eskom Heat Pump they will refund you between R 4181.52 and R 4924.80, depending on the size of the system.
Bare in mind that the rebate won't be here forever and everytime the Eskom Electricity tarriffs increase, the rebate amount will decrease and eventually dissapear.
