Hi,
I took a meter reading last night and one tonight, and it looks like I have used 780 cubic feet of gas in that 24 hour period. Just to make sure that I am reading it correctly:
- It has 4 white dials, a red dial and a fixed red zero
- It says cubic feet at the bottom
- The figure yesterday was 104380 (all dials plus the fixed zero)
- The figure today is 105160 (all dials plus the fixed zero)
It is my understanding that a hundred cubic feet is about 30 kWh, so I would have burnt about 234 kWh and I believe that my tariff is in the range of 3.5p per kWh, in which case I would have spent about £8.20 on gas in the last 24 hours.
We live in a 3 bedroom semi-detached house. Our heating is on all of the time (we have young children), the boiler seems to be running for a fairly large proportion of the day and our house is generally a bit cold and draughty (is double glazed, but with some single glazed windows and a draughty front door). I am not sure about the roof and wall cavity insulation. It is also currently quite cold where we are (probably a little above zero during the night and a maximum of 8C during the day).
We have a Vaillant combi boiler, which seems to be an older version of the ecoTEC range. The radiator dial on the boiler is set almost all the way to the right. I believe that the room thermostat (on the landing) may not be functioning, although the house is far from being too hot (kitchen - 22C, lounge - 23C, hallway - 24C, landing - 22C).
I wonder if anybody could please tell me whether I have made any mistakes with the above calculations, and whether the figures are within any kind of normal range.
Many thanks in advance,
Bob
