The main advantages of a heat pump are the ability to re-heat a geyser a few times per day and that it can work day and night, rain or shine. A solar system will only save you more money if its capacity exceeded its demand which is highly dependent on the usage pattern.
The Eskom rebate of between R3668 and R4320 depending on geyser size, is taken directly off your quote no waiting for repayments, where Solar you will have to wait up to 8 weeks for your repayment.
An 4.7kW heat pump will heat the water slightly faster than a 4kW electrical element typically found in 200L geysers. The heat pump produces 4.7kW of thermal energy under specified conditions while using as little as 1.2kW to do so.
Our heat pumps range requires virtually no maintenance of the system except for making sure the evaporator is clean from dirt and leaves. We do however recommend that the system be checked annually to ensure that you are getting the best possible efficiency out of the system. We have a monthly eminence plan called Heat Sure which also extends our product warranty to 5 years. Our Heat Pumps should last for up to 10 years.
A typical family of 4 that uses water very conservately uses about R500 of electricity per month to heat water. Installing a heat pump will guarantee you a instant saving of about R350 per month which means the machine will pay for itself in less than 3 years.
