Problem with heating

Nags14

hi all, I have a 3 bed semi, with radiators on the ground floor and radiators on the first floor. These are controlled by a thermostat on each floor. When both floors are on all the radiators are grand and warm which is hunky dory but when I just want the ground floor on only 2 out of the 4 radiators are heating up. and the other 2 are stone cold. Have any of you come across this problem before?

thanks in advance

Do the other 2 downstairs ones heat up when only upstairs is on .

These downstairs rads could be plumbed from upstairs.

hi

no it could be any combination of the 4 rads on the ground floor that heat up when only downstairs needs heat. but its always 2 hot and 2 cold. its very strange

this is only a recent problem.

before you could turn on the downstairs heating and all 4 rads would work away as normal, the same for upstairs.
