[QUOTE="chrisc, post: 1142576, member: 746"] Since water heating accounts for a large proportion of your electricity consumption, I suggest that its a good idea to devote some resources to this My solution A 200 litre copper geyser 20-evacuated tube solar collector with a small 12 volt, solar powered circulation pump. This starts in daylight 2 x 575 watt PV panels, connected to... A Geyserwise ECO controller A PTC dual voltage element The Geyserwise manages it all. The panels via the ECO controller deliver 72 volts at 12 amps The 220 volt side of the PTC element has a 2 Kw solid state heater as opposed to a hot wire you find in conventional elements The ECO low voltage cuts off when the water reached 75 deg The 220 volt side is set to 55 deg and comes on at 18h00 but obviously only when the water is below 55 deg There is a 22m run from the tube collector to the geyser. This is lagged with clip-on insulation The electricity spend from Jan 2022 to Jan 2023 is R920,00 [/QUOTE]
