A 200litre Kwiksol geyser costs R18 000 – R20 000. I nstallation costs R3 500 – R4 500. On overcast days the geyser can be switched from solar to draw on electric power for heating. Solar heaters should not be installed by families that tend to draw most of their hot water during the middle of the day. The Government rebate is R6 000 (applies only to registered plumbers). FOR HOTELS AND GUESTHOUSES: Heat pumps cost R10 000 per unit. Installation costs R3 000. The advantage of heat pumps are that hot water can be drawn by guests throughout the day, and are otherwise preferred by those who feel roof installations are unsightly.
