Thanks everyone. Didn't know about the boiler efficiency database or even that replacing the same model (old for new) could make such a difference. 18% is alot of money these days and I know, for myself, that my boiler is non-condensing so it could go higher. Its certainly something I'll be looking ...

Sorry - I should have been more clear but I think you've found where I've went wrong. Thanks tomhitchman. I'm considering kerosene only and I think the 11.69 figure doesn't apply to kerosene. Here's some variations for what 1 litre of kerosene should produce: 10.22 http://www.entech.co.uk/entech/ene...

Can't see what I'm looking for but thanks. It seems adsurd that there are two figures (10.18kWh and 11.69kWh) doing the rounds for how much energy a litre of oil produces (before boiler inefficiencies) especially since that figure will obviously form the basis of multiplications in thousands unless ...

Hi, I'm trying to compare oil with other energy types and I'm having problems getting a definitive answer on how many kWhr 1 litre of oil produces. At first I thought it was 11.69kWhr for each litre of oil as listed here: http://www.carbontrust.co.uk/resource/energy_units/default.htm but then I foun...

I know I'm coming a bit late to this discussion but there's a new site thats just started (exclusive to Northern Ireland for a change) that shows a list of about 18 different oil suppliers in Northern Ireland and how much they charge for a standard delivery of 900 litres. The prices might increase b...
