Just doing the man math on this and got to wondering whether I should stop heating my water with my gas boiler once I get on the Octopus Go tariff.
Usually of course despite the inherent inefficiency of heating water in a tank from a gas boiler, the cheapness of gas per KwH (about a 1/4 that of electric) means that it is better to use gas. However if I am on Octopus Go that gives near price parity per KwH.
So in theory I'd be better switching to use my immersion (which has a timer). Though I have scaling concerns.
Anybody else who moved onto OctoGo switch to using their immersion for water heating?
