Have I ran my bedroom flow & return correct? Photo inside.

[ToastyToes]

As per title - red is flow, blue is return. Both Tee off to provide each small rad under the window.

Both 15mm polyplumb pipe under 10m from the boiler on the same floor.

Is this okay? Thanks.

How high a rad are you planning on fitting..looks narrow ?

Surely a bigger/taller rad in between the two windows would be better or are you planning to have a TV there? Could never understand why people fit rads below windows - surely all the heat goes up between the curtain and the window when the curtains are closed although not in this case as I see you have blinds but I’ve lost count of the rental cottages we've stayed in that have a rad by a window. We end up screwing the curtains up and bunching them on the. Windowsill so that the heat can get round the room.

I assumed he is putting a partition wall in.

Never figured either,,whether its a physics thing,,more sense to heat cold air as it comes in?? Or just so you do not use up wall where you can put furniture

1000x300 ~3500BTU rads. Could go up to 400 high but don't need to.

I never really thought about the heat loss with curtains are you mentioned @Motman. Although I've always been told to have rads as lose to windows as possible to combat the cold from the windows which also makes sure the room is evenly heated instead of the rad being on the opposite side of the room to the windows which will cause cold spots near the windows.

And yes, between the windows.

This

Reduced temperature differential across heated area gives a better level of comfort.

@Motman @durhamplumber @Dan Robinson
Is the pipe layout okay then?

 

[ianmcd]

yes its fine as long as you connect to the existing pipewrok in the correct way, but most modern TRVs are Bi-directional anyway

 

[Dan Robinson]

Should be fine

Yes, I’ve read that and agree with it but unless the curtains are in a recess, when you close them they’ll prevent any heat from the rad warming the room. Look at this picture from the place we stayed in last October - we had to bunch the curtains up and put them on the window sill at night when we closed the curtains. The room was bloody freezing if we didn’t.

Thank you for sharing. I ALWAYS ensure my holes are within the correct span.
