New rad

[g1arm]

I have an existing rads in hallway and dining room but wish to add a small one in my living room.Concrete floors thus all pipes are above skirting boards. My question is whether i can tee straight into the pipes supplying the hallway radiator as this backs onto the wall on to which i wish to hang the new living room rad. All are 15mm pipes and this appears to be my only option. Any help would be appreciated.

15mm pipes will carry a heating load of around 7 kW, so if the total load (new rad + existing ones on same branch) don't exceed this by much you should be OK.
