My rads downstairs are not heating up , hot water and rads upstairs are fine.
I have read up and it more than likely the pump I have a grundfos 15 60 and I want to change this for a grundfos alpha 2. Can someone offer advice will this replacement be ok, I didn't just want to replace with same sort if the alpha2 is better.
Thanks cliff
