How long to convert from conventional to combi CH system?

[taz777]

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

How old is the system ??

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.

Hmm converting to a combi ? which = a sealed system ? every thing under more pressure ? can u see the pipes ? are they buried in the screed ? IMHO if u cannot see it do not seal it ?

Without new rads....one day
But you might/would be best to rip it all out and go from new....3 days
