    This seems like the best forum for this simple question:

    The oil fueled CH boiler in my house has been here for about 20 years. Would it be worthwhile replacing it with a newer one, going on the assumption that the newer ones should be more efficient at burning the oil?

    It's a general question, I know, but maybe somebody knows if there's a significant improvement in boilers between now and then?

    The price of oil is only going one way and it aint down!!

    If I were you I would get the specifications from the manufacturers so that you can compare how efficient one boiler is compared to the other. I think you will find that it is worth the money. I am told that the newer oil boilers are 30% more efficient. However the guy saying this was selling them!!

    I do know that sizing a boiler correctly has a massive impact on how efficiently it operates. The ideal boiler size will change as the load does. I wired a house once that had 2 gas boilers. 1 was just for domestic hot water and one for the radiators. Each was sized perfectly for its job. The result was great efficiency and rapid heating of either, even at the same time. Naturally the capital cost of installation was higher!


    As I am sure you know other cheaper changes can also have a very positive effect on your bill, such as zone valves allowing domestic hot water and/or central heating to be selected. Room stats and thermostatic valves on the radiators help too.
