The drive to make heating systems more efficient and cost-effective remains a pressing priority

  1. Re balancing radiators:
    You forgot to mention that with a condensing boiler, if you actually want it to condense, then the lockshields should be adjusted to give sufficient temperature drop so that the return water to the boiler is less than about 56 deg C, the dew point of the flue gas. Older systems like mine will have been designed for temperature drops of around 11 deg C. My boiler manufacturer suggests a drop of 20 deg, I am having difficulty getting this so have adjusted the flow temperature and I now have a nice steady plume from the flue for most of the time that the boiler is working.
