Rotating 15mm tees?

[Ian H]

Could I rotate the 2 Tee pieces under the radiator so that they point downwards then have a pair of 90’s taking them along the top of the insulation? The flow comes left to right so would hit the Tee rather than passing it as it does now.

There’s another pair of tees that go to a radiator in the living room then to the right the pipes go to a small radiator in the porch.

Reason being is that I want to make a 100mm box for the pipes along/under/in front of the door opening before I pour concrete on Saturday.

Thanks

Otherwise I could drop the pipe before the radiator and put some longer copper pieces in down to the Tee’s.

Would advise the latter. You need to be careful on the total capacity of the rads that you plan to run off of a single 15mm pipe though, there is a limit before the rads won't heat up properly, especially a tall column like that, they're especially susceptible to poor heat distribution if the flow isn't the best.

Don't forget too, that once the concrete is laid then you won't have access to those push fit joints if any decide not to play ball. Soldered copper would be the best way to go if it could be managed.

There is 22mm off to the left that I could extend to the first radiator, having said that though they all warm up very well at the minute.

I’ll mock up a 100mm box and see if there’s enough room to swap a tee over.

Thanks for the help

Good stuff, just in case it hadn't all been tested, if it all works fine .... then no worries.
