Gas calorific values

Jasnejac

Hello to all, first post.

I haven't seen this mentioned anywhere although I could be wrong of course and I'm hoping this is the right place to pose such a question.

Has anyone noticed a reduction in the apparent calorific value of their gas supply recently? To me the gas rings just don't bring things to the boil as well as they used to and I am definitely not alone. I've checked with a few around me and they all feel the same, at least the ones that cook do!

I live in Boscombe, Bournemouth and we have had major gas pipe works going on recently with almost all the pipes being replaced, which may possibly affect pressure but I don't see how it would affect calorific value - the rate of use according to the meter certainly hasn't diminished appreciably.

Anyone able to shed a little light on what may be happening?

Cheers

Well you can view current and previous values for different regions here:

I doubt any change would be that noticeable.

Perhaps gas pressure is the problem?

Tend to agree. I would contact the supplier, because low gas pressure is dangerous, so I'm told.

I mentioned this a few weeks back

British gas calorific value


Someone said this

Gas passing through the gas pipeline system has a Calorific Value of between 37.5 and 43.0 megajoules per cubic metre, with the exception of Stornaway which receives liquid petroleum gas. The Department of Trade and Industry checks the accuracy of the calorimeters, evaluates and certifies the readings every two weeks. The registered readings are in megajoules and for billing purposes, the number of megajoules is converted into British Thermal Units (BTU’s) by dividing by 0.0373
