Hi guys
Sorry for sounding dumb but here in SA we have a major electricity crisis & we the fools on the end get nailed for our suppliers mistakes . anyhow a 1.5k bill is doing well in my town so I look at everything that gives off heat & try & figure a way to use it. The govt gives rebates on using "geyser heating pumps" for preheating the hot water feed that goes to the water heaters. Sorry i see my mistake now we call them geysers you call them water heaters. this is an ac type unit that runs with minimal electricty usage & warms the water so the water heater wont work so hard to heat the household water hence big electricity savings.
Thats where I figured the fridges coil in the back is always hot. It runs about 45 C /113 F. its wasted energy why not use it?
