Dropping the flow temperature to 60c

Given that combi boilers have been around for years now why are they only now going on about dropping the flow temp? The advice for dropping the thermostat temp by 1 degree to save 10% has been around for years.

  • Because turning down the thermostat likely makes more difference, it certainly works in more situations, and prices were low enough that people didn't care about maximum efficiency as long as it was good enough.
  • Also when you drop the flow temperature too far your radiators won't get hot enough.

    are you confusing combi boilers with condensing boilers

     It's condensing boiler whether combi or not that benefit from lower flow and return temperatures
    Never under estimate the power of stupid people in large numbers

    As combis do not have a HW cylinder people can play around with the boiler flow temperature at will. With a system boiler and a HW cylinder some thought has to be given to the HW cylinder temperature.

    "They" being the government? Its public information offered now due to the fuel crisis. The information has been around for years. The heating or installation industry should have advised homeowners when the installations were done but from experience many did not give this advice or advised wrongly.
    Why can't boilers measure the return temperature and adjust their output automatically?

    Public information about setting TRVs to halfway which is 70 degrees then adjusting in small amounts over time would be equally useful as would stopping homeowners drying washing on radiators.

    Hello

    I dropped ours the other day from 67 to 65, it was ok - today is was 63 and not as cold outside but the rads did not do the business so back to 65.

    Thanks

    I'd suggest public information about how TRVs work and what their function is would be more important than saying "set them all halfway".

    Hi

    I agree 100% as setting them "halfway" would further burden people that are already having trouble paying their bills,
    Education via public info adverts/leaflets etc would be great.

    Thanks

    The full quote rather than your omissive quote, "setting TRVs to halfway which is 70 degrees then adjusting in small amounts over time"
    Suggesting 70 degrees as a starting point rather than set to maximum as they often seem to be. I agree educating their purpose and that the setting makes no difference to how quickly the room will warm up.

    So, I should go and turn up every TRV in my house then?

    Surely saying "your TRV determines the temperature where your radiator turns off - here is the range" is far more useful.
