Hi
We had our installation in July and haven’t paid much attention really, water’s hot, love the EcoDan, delighted with everything.
And then...
We’ve just had our first month’s electricity bill since having the heating on which has focused our minds. If I’m honest, we haven’t got our heads around this at all. Now we want to. We’re reading the manual and up and down to the loft, but have no idea what we’re doing.
I’ve just taken readings and calculated our COP is 2.18. I have no idea what that means really other than, based on reading these threads, it’s not great.
Our hot water, until a few minutes ago, was set to apparently heat up on demand, there were no timings set at all. We’ve set it to come on for a couple of hours in the night when we’re on economy 7. We had already set the temperature to 45 and the water is coming out of the taps at that temperature.
Eco mode was not selected. We’ve selected it.
So. For a Heat Pump numpty like me: any other basic recommended actions we can take at this point?
And a really daft question but I have to ask: the immersion switch has always been a no-no since I was a child, except when there was no other possible alternative. The immersion switch is permanently on. Is that normal with a heat pump, is it supposed to be on all the time because of the legionnaires disease thing? That is set to happen incidentally, ie the box is ticked, but we can’t see how to control when it happens, assuming you even can.
Sorry for all the questions, thanks in advance for your help
Bev
