My boiler seems to be short cycling and could possibly be due to air lock. I can hear trickling inside.
The house is a 5 bed, 3 storey with an Ideal Classic FF380 on the ground floor with the megaflo and pump on the middle floor. With 20 rads i suppose it was assumed the pump needs to be on it's highest setting, 3. I think this is causing air as the further rad needs bleeding every few weeks.
I raised the pressure at touch to 1.6bar and at warm it's 1.7bar.
I can't seem to shift the air (bled pump / rads), althought it's only the first day i'm running it on pump speed 2, maybe it needs time to settle? (there is an autovent by the pump).
But in my quest to solve this air problem and short cycling i read the manual and discovered the flow and return pipes are connected to the wrong ports on the boiler.
According to the manual, flow is right, return is left (front view). Mine are the opposite, the left pipe gets hot first. It seems the boiler monitors the temperature of the return pipe, as this is the flow (on mine), it's going to be premature shut off right? This could be the cause of the short cycling if i have this right and there is not some funny stuff going on that i'm not aware of / have misunderstood.
Would this also cause the air problem or is this most likely down to the pump speed 3 causing water to hit the impeller at high speed creating air?
The only red herring is, the boiler short cycles from cold and it's first turn off is around 5 mins. At this point the water is certainly not the 77c degrees the boiler stat is set too (setting 5 of 6). So i assume air lock is compounding the issue. To note: pump is installed with arrow pointing away from the boiler.
Any advice appreciated
