    Is power flushing a standard job?

    Heating Engineers

    Do most heating engineers perform a power flush per standard when installing new boilers, etc.?

    "Not a "Power Flush", heating engineers are required to flush the system i.e flush out all the old water and chemicals prior to installing.

    the difference of a "Power Flush" is that a special machine is brought in which is for more of a heavy duty flush, this enables us to clear blockages etc within a system. depending on how many radiators are in a system on average a proper powerflush job will take nearly all day and cost around £800"

    "No, you should get a chemical flush but a power flush takes a number of hours and is quite expensive."

    "A standard hot flush is completed with all boiler installations. A power flush however is only required if the corrosion within system is unable to be removed via standard hot flush. This can be identified via inspection of water within system and radiators. Hope this answers your question"

    "No most engineers will flush out system cold water to take out sludge before installing new boiler, install a magnifilter to protect boiler and any further sludge.
    This is recommended by boiler manufacturer and is good practise.
    Powerflush is different and takes about 7 hours.
    Costs 300 to 500 pounds 400 is the normal."

    "No power flushing is not part of a standard boiler installation."

    "Most of the time is relatively standard
    But you can get some difficult systems
    And also there is a risk of leaks to radiators and pipework due to the cleaner that is put into the system"

    "Hi there

    Speaking for myself I carry out the power flush when fitting new boiler just good practise in my eyes"

    "Powerflushing is something that many contractors claim to include when fitting a boiler - you need to be very careful and clarify this is a proper powerflush. There are many boiler installers that will say they are doing a "flush" this may be as little as draining down and filling up. A powerflush done properly with magnets will take a considerable amount of time - up to 6 hours for 8 radiators and longer for more - the system should have chemical introduced and the whole system run off a machine with all radiators attended to. A good way to ensure this is what you get is to ask the tradesman to quote separately for the powerflush alongside your boiler quote."

    "All depends on the age of the system and water quality, not all systems need a powerflush, as a heating company my boiler changes come standard with a magnacleanse flush, which is a big twin magnet which gets attached to the heating system and some cleaning chemicals we let that run for an hour while we commission the heating.
    If the heating system is bad then we will sell a powerflush which can take a full day and we charge accordingly"

    Normally a hot and cold flush.
    Unless system is really gunged up.
    This would be added to cost of job"
