Extending a Microbore Central Heating System

[Billyburo]

In anticipation of a new extension, I am looking to add a couple of runs, one flow, one return onto the dining room radiator, to allow for a ceramic floor tile to be laid. It appears to be run in 10mm PVC coated Microbore. What I would like to know is, is it safe and advisable to add additional radiators onto a microbore system, or is a manifold required, I would anticipate adding an additional 3 radiators.

Many Thanks

Don't tee into any off the microbore

The new rads pipework must come off 15mm or preferably 22mm flow and returns.

Cheers Dave,

I suspected as much.

Thanks

Billy.
