I recently moved into a new house and am looking for some suggestions.
Our electricity bill for September/October was very low, however November/December bill was €400, a lot higher than I expected in an A rated house.
Thinking that I am not using my heating system correctly or most efficiently.
So hoping someone here can help.

The system I have is:

This unit is outside

And in our hotpress we have a tank with this controller:



We have 2 thermostats, 1 upstairs and 1 downstairs, and also obviously hot water.
All the radiators (apart from the 2 in the same room as the thermostats) have thermostatic valves on them.

Can any suggest how this system should be used most efficiently?
Both in terms of heating the house and the hot water?

Thanks in advance.
