I have an OWL electricity monitor which gives readings close to my smart meter, but throughout every night (and though the day) there is a spike in consumption about every 30 mins amounting to about 2 kw.
I have tried turning off the hot water system as that seemed like a likely cause.
Our heating is gas powered underfloor and the pump doesn't come on at night at the temperature setting we have set.
This is a vital issue as even when we are away on holiday and the heating is on frost setting only, we still use 15 - 17 kWh per day!! When we are in the house is comes to between 35 and 40 kwh for an annual total of almost 12,000 kWh for electricity only.
There are only two of us in the house, which is heavily insulated and four years old.
We have only normal and up-to-date appliances - washer, tumble dryer, kitchen ovens, etc. What on earth can be causing this level of consumption?
