Thanks John. I take it is normal practice to remove this link? The only reason i can think this link is put in place is to get the boiler going even without a thermostat? This cause of short-cycling would explain significantly higher gas bills even during summer months. Really hurts knowing that...

@Johnmdc - been away for work. Got back today and checked that 24VRT link has a little read wire linking two terminals on the connector (photo attached). I take you are asking for this to be removed to check if the short cycling still happens? @terryplumb - sadly, pretty ugly story with the...

Thanks Terry. At least it rules out valves related issue. The whole setup boiler, plumbing/pipes, rads everything put in place 8 months ago and ha e had no trouble with it. I am hoping it is nothing to do with the components and more to do with configuration/setting. Hopefully the wiring as it...

@ianmcd @terryplumb - i have now removed the only remaining connection from the two valves. I have attached the wiring image as it was befire i touched it and now. There is no change in behaviour. The only other thermostat apart from Hive is the one in the hot water tank as far as i am aware...

I have removed the wiring from the wiring centre except the ground connection from both valves. Attaching images. Grateful for your contunued assistance.

@ianmcd and @terryplumb:- i have gone all out and completely disconnected the valve head from the electric circuit. Yet i still see the same behaviour as previously described. Is it safe to rule-out atleast the valve-heads to not be the cause? Not sure what to check next? Flow temperature is...

@terryplumb - yes it is very likely i have introduced this while putting the actuator head back on the valve. @ianmcd - i have a feeling that this may be the HW motorised valve causing this. how do i go about fixing this? Do i have to replace the motorised head?

@terryplumb - the boiler is going on short-cycle when there is no CH and HW demand. Ian's asked for a photo of the boiler display when it comes back on and short cycles. This is what i was referring to in my previous message.

This is now resolved based on comment from Ian. At present i am switching off the boiler from mains once pump overrun has completed and before the boiler/pump has come back on until i have actioned on Ian's comment.

Thanks Seb. The pressure on the analogue gauge is not the same as the pressure displayed on the digital display. Bumping up the pressure using the filling loop does not increase the pressure on the analogue gauge but does on the digital gauge. Is digital and analogue gauge both meant to display...

Massive thanks to Terry, Picasso, BoredSeb and Ianmcd. @ianmcd - while i do not recall for the life of me to havw touched isolation valves for Magnaclean and certainly do not recall isolation valves' initial position. However, turning on the isolation valves for Magnaclean resulted in...

I have double-checked and bled the radiators all round the house. Had no trapped air in them. Followed the instructions kindly provided by Terry and Picasso. I have a couple of questions: 1. What pressure is the small guage to the right of the pump in attached image 1 is displaying and does it...

I have tried them in different positions and the result is the same unfortunately. When i keep it in what i understand is the open position and the tank's immersion heater is on, i feel the pipes upstream(boiler end) of the valve gets quite hot but when the boiler is on downstreams of the...

Thanks Terry for your response. I have followed your instructions, turned the pump a good 20 odd revs. The situation has not changed. Pump goes into overrun (as per live monitoring) in a minute or two which i take is expected to disperse the heat. The hot water flow out from the boiler is hot...

Is it the little grey cap behind the connector on the pump in the first photo? I do not recall touching it. Does it need to be like half a turn or so of being thumb tight? I have double checked and it is about a quarter to half a turn of being thumb tight. Does the pressure on the guage next to...
