If you are an individual home owner, game lodge, bed and breakfast operator, a metro, buying in bulk, or a corporate organisation, you can take advantage of Eskom’s heat pump rebate programme.
Rebates only apply when you are retrofitting or replacing existing electrical element geysers. Customers who already have an electrical element geyser with a capacity of between 100 litres and 500 litres are eligible to purchase rebated heat pumps.
Customers can buy a heat pump at rebated cost from the accredited, published registered suppliers (Please see below Heat pump suppliers list) on the programme, and the supplier must perform a full installation.
Heat pumps sold by registered suppliers are already rebated by Eskom, so you don’t have to apply for a rebate personally. You get the rebate upfront, without any delay.  -------from ESKOM
