Hi guys, I have just bought a 1960’s bungalow and found out that the entire plumbing is dire ( so are the electrics but that’s another issue).
I want to replace the dodgy combi boiler with a proper system with the tank, and replace most of the corroded and probably clogged pipes with new. I am planning on fitting solar panels later in the year so will need a cylinder anyway, obviously I can’t fit a mains pressure tank as a diy job, but as the house only has a 15mm feed I think a regular loft tank / cylinder would probably fill a bath faster.
I have fitted numerous diesel fired central heating / hot water systems to yachts but am not sure of the regs for domestic installs so here are a few questions.
Am I free to use Hep20 pipe and fittings for heating circuits and mains feeds to the feed tanks in the loft? I figure if I use plastic pipe with 3 inch foam insulation it will be far more efficient than the 1960’s fibreglass wrapped around the pipes under the floor. Obviously I have to use copper around the boiler.
Is there a standard for rising main sizes, expansion pipe sizes ect? Did I read somewhere that new installs need pressure testing and disinfecting before use?
In your opinion can I carry out all the plumbing except the gas in readiness to have my combi boiler replaced with a ‘proper’ boiler by a proffesional.
As I will be replacing all the heating pipes hopefully with Hep20 would it be easier and cheaper to replace my 6 rads than getting them power flushed if this is necessary before having a new boiler fitted? I know I can flush them through in the garden but I guess for the boiler warrantee they would need to have a reciept for being proffesionally flushed.
Better stop here before this post gets too long.
Thanks in advance for any help.
