New radiator on one pipe system, is this ok?

[emphasis303]

Hello everyone

Ive just installed a new rad into an existing one pipe system

I've cut into the pipe and teed up out of the floor so that a single pipe is above ground. I then teed off of this above ground pipe and connected up the return to it. The tee has been made 10cm below the rad valve.

Is this ok? Will my rad heat up properly? I was worried i should have teed the two pipes from below ground. But access was an issue.

Cheers[/b]

Yeah it should have been done with both connections below ground, this'll never work

The further appart the tees are placed on a one pipe ring the better , yours aint gonna work.

It wouldn't work on a two pipe either.

Oh dear.

Sugar! Why won't it work, I only did it bcos I saw it someone's house and it was fine???

What you probably saw was a bypass and missed the other end going up behind the rad or back down through the floor.

Physics dear boy, physics.

One-pipe on modern rads doesn't always work even if you plumb in properly.

I thought, if it's teeing from the same pie anyway what difference is it going to make teeing closer to the valves.

I thought the boiler pump would just hear all the water anyway and pump through.

Should I try the rad first and see or stop wasting even more time?

The plus side being the floor tiles haven't been laid lol!
Many thanks

The water has to leave the ring one end and return at the other , your way fails to leave a path for the water to return to ring , water won't flow two ways through one pipe.

So the rad will get hot once then not again.

Well the same could be said for any rad on anyone pipe system right?

The only way that rad is gonna get hot is when you fill it for the first time with the heating on.

If I tee from the main pipe into the horizontal run before the pipe gets to the right valve will that sort it?
