    Best way to clean central heating system? 1st Aug 09 at 5:55 PM
    Hi all,

    I've installed a spirovent Air and Dirt:

    http://www.spirotech.co.uk/en/products/dirt-separators/

    On my central heating system and also upgraded the previous Grundfos 15/50 central heating pump to a Grundfos 15/60. I started to notice last year the rads were not warming up as well as they used to.

    I wondered what the best methodology would be to clean my system without the need for a power flush how would I go about it. My initial thoughts are:

    (1) Close off all the vales on the radiators
    (2) Set the Pump on level / position 3 the highest setting
    (3) Put on central heating system
    (4) Then open one rad at a time for about 5 minutes so the sludge can be taken away to be caught by the Spirotect air and dirt device.

    Repeat cycle above for 2 -3 times hopefully the sludge can then be removed from the air and dirt filter. After this then dose the system with a new chemical inhibitor.

    Does any one else think of a better way of cleaning the system without the need or a complete drain down of the system?

    Thanks in advance
