    My Worcester Bosch Greenstar 35 Combi boiler has just been serviced under an annual Homecare agreement. The engineer has provided me a form with only 'tick boxes' to say that it has passed. He has however, written in the margins the following measurements:

    35.29
    9.4
    0.0006
    62 ppm

    What do they represent and what are the tolerances for this type of boiler?

    He has also made a suggestion of fitting a "Magnabooster 22mm Combi" to prevent system clogging. It apparently comprises of a magnet which attracts particulates within the system. The boiler is only 4yrs old and the radiators were flushed during installation. Is it worth the cost at £230 a pop?

    Cheers

    35.29 = kw input rating.
    9.4 = CO2%
    0.0006 = ratio CO/CO2
    4.3% O2
    30% Xs air.
    62ppm = .0062% carbon monoxide in air.........1% would be immediate death within 1-3 minutes. :mrgreen:

    Those combustion readings are spot on.

    System corrosion can be more of a problem for modern boilers, as it can lodge in the heat exchanger. It can cause a loss of efficiency and eventual breakdown. Some systems suffer more than others.

    Obviously it is better that any corrosion is caught in a filter before it enters a boiler. Making sure that you check the concentration of corrosion inhibitor in your system helps keep corrosion to a minimum.

    I would be going for the Fernox TF1 if it was me.

    Better than fitting a filter to catch crap, is cleanning the system to remove it and then treat with inhibitor.

    Unless you read the O2 and excess air off the analiser printout how can you possibly know the figures. :rolleyes:

    Are you sure thats correct?

    (In fact I think it is but it just looks wrong!)
