That's the point I am trying to make. This is the way all these houses in this estate were installed in 1984.To run in entirely new pipe would be a nightmare as the pipes go from under the house up through stud walls through floor joists and behind stud walls.In addition I’m not sure plastic is the most sensible straight off the cylinder. Someone really needs a word in your installers ear
All my house has been done in plastic.Also good swerve on the issue with the plastic
Tank is fitted with a 6 bolt howden which has one control thermostat and an over-temperature safety thromostat for protection,this complies with the current IEE REGULATIONS TO BS7671.If you had read the post correctly the pipe runs up to the cold tank which means if both stats fail and the tank over heats the superheated water will flow into the cold tank in the loft.THE HOT WATER IS TEE,D OFF THIS VERTICAL dare l say it VENT pipe.They can’t deal with the temp should your cylinder overheat likewise your vent pipe needs to be correctly reinstalled in copper. Who re-pipes it all in plastic?
