Hello all,

I need to reboiler my place.
The boiler is at least 45 years old and obviously cannot last forever.
I am somewhat older and the same conditions apply.

The supply to existing boiler is 1/2" steel pipe.
I'm told that I need to have a 22mm supply for a new condensing boiler.
The routing of existing pipework cannot be followed without demolishing
about half of the interior of the house. I'm not willing to do that.

Would it be legal to run the majority of the pipework in armoured
rubber/flexible pipe?

Im not an expert but I doubt it very much!

Things to consider, if your boiler is on an outside wall, the pipe could be
routed externally. Not pretty but would avoid internal disruption.

If your boiler *isnt* on an outside wall then its probably discharging
into a chimney. This will be hard to do with a new boiler (as the flue
must be accessible for inspection). Consequently you may be looking at
boiler relocation and replumbing.
