STRESSED!!!
Hi guys... Need some pointers!!
I installed an ideal logic plus combi a few months ago... The rads upstairs get red hot but the downstairs rads are cold. The flow gets red hot but nothing through the return. They're all 1200 x 600 doubles on 15mm drops.
I've flushed it, taken rads off, replaced pipes but nothing!! I dragged some water through the TF1 and carefully balanced all the rads out.. Were lovely and hot until the boiler switched off then as soon as it fired back up the downstairs ones were cold.
With just the upstairs rads on the return gets hot to the boiler, but when I open the downstairs rads the return becomes cold!!,
I'm pulling my hair out with this one,.. Literally!!! I'm thinking air locks but why is it going again after it sorts itself???.
Thankyooouuuuuu
