    How long does it typically take to convert a conventional boiler to a combi central heating system?

    The property has a conventional boiler, tank with immersion heater and two tanks in the loft. I would want:

    * All tanks removed
    * Boiler replaced with a combi boiler
    * Possibly new rads (say, 7 in total)
    * Possibly a Powerflush

    Probably very old - could be decades old! It has been regularly serviced and the last service was last year and all was working. It's in a property that i'm looking to buy.
