a lot depends on house size ... and the readings is the Gas Cubic meters or hundreds of cubic feet for the same period I have 1500kWh of Electric and 5775 kWh of Gas your electric consumption is 25% less than mine .... bummer.... but your gas consumption is way higher... maybe the boiler was a good investment. remember my electric consumption is import ie what I pay for not get free via the panels my Gas Is higher cos my figure was kWh not cubic metres, in cubic metres I used from 13/3/22 - 14/4/23 760 cubic metres ( for 12 months it was 694) I have my flow temp set at about 55 degrees as that allows the condensing boiler to do its job ie condense, most people run at 70-80 and the boiler then doesn't condense and is less efficient

Totally agree with your statement about total possible gas energy measured against what ends up in the water, however what over all we are interested in is what proportion of the possible energy available from the fuel gas and electricity ends up in the house envelope heating the rooms required . After all that is the system function, including heat losses from pipes under floors , water pump and control electric consumption. As I say measured where against what. If compared to electric bar fires the bar fires would be 100% efficient, however I would not like the bill . Of course that's ignoring all generation and transmission losses.

"If and when it dies, I'm going ASHP."You, Sir, are a VERY brave man! Nah, not really. Old house with thick, THICK stone walls and massive thermal mass. Takes days to heat up, but stays warm with very little input. Wet UFH downstairs, oversize "old-style" rads upstairs. Space to locate it just away from the house, near where the boiler currently is. Several local friends have them, and they're working just fine. Even better, we'd get rid of the big gas tank just inside the back gate, and move to bottles for cooking (don't want to go 'leccy there).

Read this clap trap. www.theccc.org.uk/publication/a-net-zero-workforce/ There is potential for the Net Zero transition to create more jobs than will be lost. Between 135,000 and 725,000 net new jobs could be created by 2030 i love the word COULD. IT EXPLAINS EVERYTHING,. |

Slowly but surely the facts are/will unravel... iv said it in numourous posts.. we need to live with climate change and stop thinking we can alter or stop it.

Yeah, I mean if only Greta was around during the last ice age. She'd have told us all to fk up our lives in a different way which would have reversed the coming of the ice and cold. I don't think.

Or during the roman age 2000 years ago when grapes and wine were abundant in the uk. The Romans introduced winemaking to the UK, in a period with a relatively warm climate. Their vineyards were as far north as Northamptonshire and Lincolnshire, with others in Buckinghamshire and Cambridgeshire, and probably many other sites. wikipedia.

I think we need to put this here again... Yes, the temperature has changed before. NEVER so much, so rapidly. xkcd.com/1732/ |

Quoting purely from memory, so may have this completely wrong, but don't they drill out deep ice cores and look at the level of dissolved CO2 in the ice at different stages in the past? The level of dissolved CO2 being directly related to the temperature at that time. Something along those lines, I seem to recall anyway... Basically, good and clever science.

So couldn't resist a 5 minute google after reading that. The below seems a fair summary. It is established that the further back you go the less accurate these temperature proxies (such as ice cores) become. And in general it seems far from an exact science. So the cynic in me wonders if there is any bias when producing pretty graphs such as the one AdrianC linked to ? www.theguardian.com/environment/2012/mar/07/past-climate-temperature-proxies
