Problem is it is the same design as before the only thing I have done is replaced the bathroom rad with a heated towel rail and replaced the flatpanel rad in the sitting room with a big double panel one, i know for certain that there is no blockage in the system because when I did the work I used the rad valves to get water down the dead legs on both sides of the rads before I connected then up.a standard 15-60 eg ups2 or ups3 will be more than good enough for your system but it sounds like you have either a design issue or a blockage changing the pump
Won’t change much
yep head in meters and the flowrate in M3/hr and power in watts and it is on proportional pressureThe Alpha3 may display the head in meters, the flowrate in M3/hr and the power in watts, does it?.
What control mode are you running it on, CC (constant curve), CP (constant pressure) or PP (proportional pressure) ?.
Give us the numbers then please , and the PP setting, should be a good indication of whats happening.yep head in meters and the flowrate in M3/hr and power in watts and it is on proportional pressure
I'am not saying the pumps are bad, I am saying they are not powerful enough to pump the water round the system because of the dead legs, I am going to do an experiment tomorrow and will let you know the outcomeIt’s not a pump problem as it’s very unlikely you have two bad pumps out the gate
You sure it’s not a one pipe system?
Can you get any readings from the pump as it will reveal quite a lot IMO.I'am not saying the pumps are bad, I am saying they are not powerful enough to pump the water round the system because of the dead legs, I am going to do an experiment tomorrow and will let you know the outcome
