Hi Guys,

Looking at replacing an old(10 years ish) back boiler with a new combi boiler in the loft and getting rid of the header tank and other tank.

Any one done this and what sort of Savings did you get on heating bills etc?

Also a guy I know used all push fit plastic pipes for a house re fit of CH, are they ok to use throughout the house?

Cheers

There's alot of work to fit a boiler in the loft :

-You need lighting installed (not temporary lights)
-loft floor needs to be boarded at least a walkway and an area around the boiler
-Fit handrails around the loft hatch
-Have loft ladders installed (can't use step ladders for access)
-You need an electrical socket near the boiler, for testing equipment etc.
-There has to be an ECV fitted to the pipework before it enters the loft.

etc etc.

As for the pipework - i'd go for copper everytime.

Thanks for the reply

Nothing sounds too difficult there.

I have a fixed pull down loft step ladder, is that ok?
Already light, floor boards and electric sockets in the loft so thats fine
And can fit hand rail round inside of loft hatch easy enough.

Why do you say use copper? It's more expensive harder to work with and longer to fit.

Thanks for the advice

Copper pipe with soldered fittings wont fail if cleaned and soldered properly, plastic push-fit fittings can and do fail, I have sen the damage in brand new apartments where a push fit fitting has come apart.

I wouldn't have it in my house, that's why I wouldn't recommend it for anyone else. I've never used it, but would if a customer insisted.

I've used it, its ok, but copper upto rads.
It's ok as long as you are careful with the fittings.
