Is it possible to Powerflush and fit in a boiler in a day?

[TheFunk]

Hi,

I've just had a quote for replacing my boiler and the guy said he could powerflush the system and install it in a day. is this timescale realistic

Thanks

Depends on how long his day is or if he is working on his own etc.

Personally I always allow 2 days for a boiler change and a power flush.

A small combi system Mebbe


but as daves two days minimum really

maybe his powerflush consists of 1-2 hr powerflush !! and then a long day, all depends how easy things go...i'd say 2 days also

Just an RGI's input here.

Quoted to pull out a Worcester Heatslave and install a Greenstar with neccessary upgrades.

With 2 people it was a 3 day job, as after powerflushing, all rads had the 'half moon' of cold on them. All rads removed and manually flushed, then system re-powerflushed. I done it free it in my quote as boiler was not working when I priced the job so I didnt know the system was sludged so bad.

So in summary, a powerflush is a waste of time on a badly sludged system!

Maybe I should have estimated but a quote is a quote and I was happy to do the work free.

Agree Dave, had a couple recently that have needed 'more' than a powerflush.

It is not all that it is sometimes cracked up to be

How ya doing anyway

Good thanks Dave. Getting over recent events and still repairing those dinasaurs out there!

I hope your well too Dave

A good guy would slash the heating pipes somewhere handy to the boiler and connect the machine up first job, that leaves him free to remove the old boiler and fit the new making the final connection as the last job.

How many times have I seem a plumber stand around all day watching, a 6 hour powerflush is actually about 2hrs work.

not helpfull.

All decent RGI's isolate the new boiler on a powerflush.

How can you stand around during a power flush when you have to keep opening and closing the rads valves in turn?

Agree with most people, 2 days, you don't know whats in the system untill you start cleaning. To get a good TDS reading can take ages. If its booked for 1 day it has to be thrown in, no such thing as a quick good job!

Pull your fingers out boys, one and a half days for a swap. First day flushing and half day swapping boiler and commisioning.

WoW that must take at least 2 mins each time, that means Tony, you open and close a thousand valves during an average power flush

No you flush each rad in turn for five minutes in each direction so thats two valves every 10 minutes.

In practice you would flush each in turn to drain first before adding the chemical and starting the serious power flushing with chemicals when the water runs clear.

To do a powerflush properly can easily take a day if the system is heavily soiled and/or has a lot of limescale in it which is usually the case when it is open vent.
If all the pipework is fine, is a built in, roomstat and valves can stay, you can do a swap in one day. Not often the case though.
Powerflush AND installation in one day? Very unlikely to be done properly.
Just out of interest, what boiler do you have and what is the one quoted for?
