Hello
Welcome to the world of the heating installer, each of whom has their own idea of how to improve heating systems.
I have been doing this stuff for forty years now and still learn something new every day.
If I was you I would reiterate everything again (if you want to) type of...
Hello
Yes it does sorta, it may be better you take a little time out during the spring and summer and re-pipe your system in the old y plan way and put all your radiators on the ch side of the 3 port valve. try do a little diagram of how you think it is piped now, and post it.
When the expansion vessel was installed on your appliance and the system filled with water did water come out of the air filling valve if you pushed it in?
Hello
You say the system is working ok, radiators are getting hot and hot water ok, pump is on number two and all rads from your posts appear to have been bled numerous times. How long has this been happening and what controls do you have on your system, i.e trvs three way valve, etc etc.
Hello
Your Rayburn is a combustion stove and therefore should be open to atmosphere and is a small circuit in it's self. So your flow pipe from your Rayburn rises up to your hot water cylinder coil, and possibly from there a expansion pipe will continue to rise into the roof space and...
Hello
Sounds like an old y plan system with a twist. Usually the flow from the boiler came directly into a 22mm tee from which the expansion carried on to the f&e tank, the cold feed dropped into another tee a short distance away before the 22mm dropped into the circulating pump and then the...
Try to determine through a process of elimination what the increase in temperature does to your appliance, does it increase the pump speed, does a bypass valve shut, what? Most boiler service instructions include a flow chart showing the operation.
I am still convinced that it is a over heat...
Mmmm
I dont remember saying anything about weather compensation, or did I, I don't recall.
The problem with this forum is you get advice from people who really don't understand heating systems, flow rates etc etc.
Mysteryman is right about one thing your system is not too large, however a...
Hiya
Yes water should be in the expansion vessel, it contains a bladder like the ones in old footballs. This is filled with air and the rest of the expansion vessel is filled with water. Water does not compress but air does, so has your system heats up the water expands and compresses the...
Hello
From what I can gather is that you are re-newing your boiler and retro fitting it to your old system, I could be wrong but I will push on as though I am not.
You have two problems. 1) Dirt and possibly sludge within your old system, this can only be dealt with by cleaning it with...
Hello
I am not familier with your appliance, however expansion vessels are installed to take care of expansion within your heating system has the temperature increases. The flexible pipe most likely connects to the heating system within your appliance and yes water should come out of it...
No the high limit stat number 20, test this when the boiler next locks out and see if this has tripped, if it has then you have to determine if it is tripping at too low a temperature, or is the water in the boiler too hot, and if so why.
Yo stated earlier that if you increased the water...
