Oily Rag has some very good tips on saving hot water costs which inspired me to check my hot water cylinder. I found it to be very well insulated but there’s a one meter long copper pipe coming out of it which is always too hot to touch. The heat loss from this pipe must waste a lot of electricity over time. Anyway, I was just about to throw out two old pillows but instead I’ve tied them around this pipe with some old rope. It will be interesting to see if this rather crude insulation has any impact on my electricity bill. I’ll let you know.
