Cart Before the horse ?

[John M]

If when replacing a boiler, do ya clean out the heating pipework 1st then add new boiler ...... Or do ya add new boiler then clean it all out ?

Decisions decisions

 

[JohnD]

If you possibly can, you clean out the old one (so it isn't holding lots of rubbish that it can dump into your new system) before you fit the new boiler.

Ideally add the chemical cleaner and circulate it for a week on the old pump, then powerflush, then drain and remove old boiler.

I dont remember the horse I was sent riding on when 12/13 doing that.

Was sent horseriding on Sunday mornings while parents had two hours peace in the pub.

What should I use to clean out a Primatic system ? ........ The way the drawings are going, I'm only going to be retaining about 20 feet of 22mm at the most ........ Should I just change the lot & stop buggering about ?

So I'm ditching, boiler, rads, cylinder, Keeping copper water tank in loft & bout 20' O heating supply tubing.

It was going to be more ....... But we had a bit of a incident & the lounge wall fell over (My fault)

 

[JohnD]

ah, Primatic You didn't mention that before.

Not usually supposed to use chemicals in them.
