I have a potential customer who has a duplex apartment and who wishes to exchange his old system boiler with a combi. The construction of the apartment makes the pipework problematical. It will be a huge amount of work and disruption to lift the floor between the boiler and the old airing cupboard.
He currently has no electrical stats at all. The cylinder temperature is controlled by a tap stat and this is supplied by a length of 15mm copper running under the floor from the boiler to the airing cupboard. Fortunately, all of the other pipework I need to connect up the new combi is in the cupboard containing the old boiler.
I am going to power flush the system obviously, but I am not sure if the old 15mm bit of copper is going to be suitable to use for the DHW supply. I can of course connect the flushing machine to both ends of the copper and dedicate the entire flow to cleaning this one section of pipe.
My question is, has anyone made use of an old bit of primary pipework like this for a new hot water supply?
