In winter we have some random days decided by EDF (usually several together) when electricity costs much more than others. But it is still cheap between 1 am and 7 am.
Since it has been so cold we have been letting the cat stay in at night and then getting up to let him out at some time in the night when he starts scratching at the bedroom door. So lets put the dishwasher on when we get up in the night.
Yesterday I decided to do washing before realising it was one of the days. That's ok just flick the switch when you get up in the night.
But we still seemed to be using a lot of expensive electricity during the day. What was still on? This morning Him Outdoors investigated the water heater further. He had already plugged a timer into the plug underneath it so that it would only heat the water at the cheap time. It can't be that......................
Oh yes it can. After further peerings in the gloomy cupboard it transpires that the socket to which he has applied a timer is for the outside socket - nothing to do with the water heater at all! And although we can both remember requesting one, there is no socket that has anything to do with the water heater.
So more switching in the night.
