Birthday Party

So it is a year today that I had my smart meter fitted.

Here are the readings

 

Total 3256 kWh, Mean 8.9 kWh/day

Day 574 kWh, 17.6%, Mean 1.56 kWh/day

Night 2682 kWh, 82.4%, Mean 7.33 kWh/day

 

Considering it was a cold start to the year down here, not too bad.

Looks very good, assuming 25p day rate and 17p night rate your energy cost you: £599 which is £50 PCM all bar the shouting - bloody good.

energy cost

I was going to look that up, but as it has been changing too much over the year, I could not be bothered.

Having said that, I should be able to download the prices, though I did have several weeks when the communication hub was not reporting, and EDF decided that I had used £100s every month.

That’s impressive. Know how much is ‘baseload’ i.e. fridge etc? What kind of heating, sorry I forget. Also, per m^2, so we can compare?

I am currently working on the detailed statistics i.e. mean power/energy, max power, min power above zero, percentage zero power (base load is not really relevant to me as I have cut out parasitic losses).  Shall get the temperature data in as well in time.

I have been spurred on by our old mate @Ed Davies writing up about comparisons between his CurrentCost meter and his Smart Meter readings (I have the posher CC logger, so will be interesting to compare).

 

My house is 48m² in total, mid terrace, 1987 build with simple modifications i.e. extra loft insulation, secondary glazing on the double glazing (except for two opening windows for safety).  The heating is all electric storage heaters, but with extra lockout timers to limit the E7 to four hours approximately, water is the same.  This means that the heating is done 'last thing' rather than 'first thing'.  Though I may change the DHW heating times as I start work much earlier now and extra heating is done unnecessarily.

 

So the overall energy usage is 68 kWh/m².year, just heating and hot water is 56 kWh/m².year.

That works out as a mean power of 6.4W/m² for space and water heating.
