Microbore heating system

makfli

I need to replace my central heating. I have a bungalow approx 40 years old and the old pipes are gun barrell running under concrete floors and are starting to leak. Plumber has suggested replacing with a Microbore system where the heating pipes can be run down the corner of the walls to the rads. Grateful for any advice or info on good/bad experiences.
Many thanks

Have never had good experiences with Microbore and with the new condensing boilers I imagine this will worsen.

After that....Meh....

I didnt think anyone fitted microbore systems anymore , i would stay away from them personally.
The most common complaints of the system are that blockages develop easier and the pipe can kink or become dented easier .

A micro bore system is probably fine if the system is maintained well and often, as in, inhibitor is checked and added too and the system is chemically cleaned out every few years, but lets be honest, that probably won't happen.

Can you dig up floors or is this not an option?

I'd stay away from microbore ,you'd need a manifold with it and that'd be messier than standard pipe.

It's possible to place drops where they can't be seen ,behind curtains ,behind doors etc. One drop in standard pipe could do two radiators back to back.

If you have partition walls in the house ,it's possible to hide pipe inside it and have it come out behind the radiator ,with minimal marks on the wall.

Keep away from micro bore: break your heart.

Consider internally insulating the external walls and hiding pipes there-in

Just remember where they are when hanging the family portraits:)

Thanks to all for input, think the general consensus is to avoid microbore. Looks like have to figure out a way to hide the dropped pipes.
Many thanks .

aaaagggghhhh. Don't mention that word here. If you ever need to get work done on the system it WILL air lock when refilling and it is a nightmare to get out.

If it a bungalow use a drop system and run the main pipe's in the attic if possible.

With the drops you could put into stud walls if you have them.

Thanks JohnnieK . yes it is a bungalow so will put main pipes in the attic. Unfurtunately all internal walls are block. One of the options is to dry line all ext walls and hide the dropped pipes in the lining. looks like an expensive option.
