Gas consumption

david1889

I live with one other person in a 3 bed Victorian terrace house and last August I had a very old boiler replaced with a new Worcester combi boiler. The guy who installed it said that my gas consumption would reduce drastically.

My consumption seems to have gone up by about 10KWh per day rather than down. Nothing else has changed with the house. I have a gas cooker that is used about the same amount. Does anybody have any ideas why this might be ?

Where are you getting your figures from? If you're comparing last winter with the one before, could it just be that this winter just gone, was so much colder?

From the electricity bills. It could be I guess but it seems strange that it has gone up so much when it should have gone down

What do you mean electricity bills dont you mean gas bill

A new condensing boiler is a lot more efficient but because last winter was a bad one you probably dont see much benefit is reduction is fuel

I would check three things:

1) Are there any estimated readings on your old or new bills? If so, you won't know how many kwh you were using for that billed period.

2) Are the billing periods the same? If one contains non-heating days, that would distort the figures.

We are high users - we are a family of six so that's a fair bit of hot water (no shower yet) and we cook by gas. Three bed house on three floors, poorly insulated Victorian with cold extension and someone home all day. We average 155kwh a week this month so about 22kwh a day. Winter, it varied from 344kwh a week to 1100kwh a week. Most weeks it was 700-800kwh but we had a few weeks over 1000kwh so the cold weather this winter has made our average much higher than it would have been if we hadn't had all those 1000+kwh weeks.
