Adding a radiator to an existing microbore system.....how easy or otherwise is it?

Question

I have a radiator outside the bathroom in the hallway and would like to either move it into the bathroom or else add an extra radiator. Does the fact that it is microbore pipework complicate the issue? Can I add an equal sweep joint in microbore?
All sensible replies much appreciated.

Answer 1

Whilst lots of alterations are physically possible to do microbore systems are designed to have each radiator fed by it's own microbore pipe from a manifold, often four way upstairs, four way downstairs, 22mm. Moving the existing rad. providing it works ok now, shouldn't be a problem. If adding a new rad. I would prefer to gain the feed for it from the manifolds if there is a spare outlet/return. If not I would "tee" in to the 22mm and reduce to your microbore size. Microbore has been around for a long time, at least 30yrs, and 6, 8, and 10mm has been used for it. If it gets kinked/flattened during installation/alterations there is a possibility there could be flow rate problem especially if you tee off the microbore itself to feed two radiators.

Answer 2

You can insert tee pieces into a micro-bore system providing that you do not exceed the design load and resistance on that circuit. If both the radiators are small (total of say up to 6000 Btu) then you should be able to split an 8mm circuit. Otherwise, you will need to run a separate 8mm circuit back to the manifold and connect to a spare branch if one is available. If the pipes are 10mm then there should be no complications.

Answer 3

To be on the safe side transfer the existing rad into the bathroom, or better still install a modern convector in the bathroom, I find you cannot overheat a bathroom !!!!!!!
Put an adaptur on the microbore to convert to 15mm, and run it in plastic pipe, use inserts and fittings designed for plastic pipe..
If the existing rad was never very hot, you might have to go back to the manifold, usually under the landing floor.
Put inhibitor in the system

Answer 4

i do no longer think of it quite is in all likelihood to crack Bentyler. The copper used is extremely gentle and that i might say you would be pleased with mushy bending by potential of hand, needless to say warding off sharp kinks and knocking down of pipe at that factor. different disadvantages are leaks appearing the place pipe enters valve, and, limescale or silt being dislodged and amassing someplace, (which one relies upon on no count if an inhibitor is interior the equipment or no longer and how in many cases new water might have been presented into it by using the years). I had 10mm equipment in residing house, (with inhibitor) ran for 20years and nevertheless ok when I offered the residing house, superb. most of the flaws we hassle approximately by no potential take place, so provide the mushy bending a pass, have pipe heat in case you are able to, and shop your hands crossed, :-)

Answer 5

No probs except to give it a good clean out first.
Normal fittings apply.

Answer 6

Don't know.Maybe you should get someone to check it out who knows about these things

Answer 7

You can take one out or add one.Goodkuck

Answer 8

Should be straight forward.
