we are talking about the main heat exchanger which does heat up without openiing a tap but only when ch mode. The burner shuts of with temp gauge showing only 75sh (which takes 30 seconds) but the pipe is too hot to touch and the HE makes kettling noises. it

Good Morning Agile - I do understand about the pin gland - Would mean replacing seal around the pin coming out of the valve - Thank you for clarifying. What I meant was that maybe the condensation was from other sources than the valve because crack on glass cover. Latest - The Plate HE...

Re: DHW switch removal Initially I was going to take of the Diverter Valve to check it but realized it has too many bits attached to it - some pipes, DHW HE, etc so opted for the back door method - it was painful but having small hands was a help. When screwing down the glass cover, i...

how long after firing up should the HE stay cold?

No - I have not yet - The output pipe is too hot for touch so I assume the HE will be hot too. The flow pipe heats up beyond touch after a minute or two. I am not at home now but I will do that test and post. What will the temp of HE from cold indicate? The pump (CP61) was heating up so I...

What makes you think I removed the gas valve? If its the fact that I removed the DHW switch then please be informed that it is possible to take that off and replace it without removing the GV. I took off the ignition module Brushed aside the cables and made an opening so I could see the...

they are 22 for feed and return with branches of 15 to each rad. 1 what are the circs for Plate HE being beyond repair? 2. what do I use to clean the HE? 3. Could it be main circuit temp probe at fault due to fact gas is cut off at about 75-80 instead of 90 although gauge reaches 90...

Thank you for quick reply at this time of night. The HE does quickly overheat from cold(within a minute) - that is the problem - the burner does not stay on for long for heat to travel most rads. I dismantled the two diaphrams - Big one for DHW and smaller one facing the front (CH) and...

I have at home a Biasi 24s in an average 3 bed semi with 8 radiators, HW works fine but I am sure it used to be bit hotter when set at max. The pressure is set at 1bar but I have experimented by increasing to 1.5 The issue is with CH. The boiler fires for only 30 seconds after a few...
