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!


There is something called tracpipe?? which is flexible stainless
steel pipe intended for gas, which has fittings at each end to
join up with existing pipework. This could? be wangled through
the ceiling void if needed.

Looks good stuff, but £15-20/m. Mind the way copper pipe is getting more
and more expensive you never know it may be cost effective and
convenient for DIYers!
