    Gravity based back boiler CH system - Advice needed.

    Ok. Thanks for the feedback and the pictures, that doesn't look good for sure. Can you give me an example of the kind of product I will need to replace it? All the products I can find in searching are in-line airators, but these are 1 inlet and 1 outlet, how do I accommodate the overflow pipe...

    Gravity based back boiler CH system - Advice needed.

    I've replaced radiators because they started leaking. I only had to drain upstairs once, the other times the valves held the water at bay. You are correct in that no inhibitor is in the system and that the system is full of ****, likely causing rads to fail (although its the newer stuff that...

    Gravity based back boiler CH system - Advice needed.

    Thanks. I will validate this, but I know the water is hot at the tap, it will burn you if you leave your hand under it, ask me how I know.

    Gravity based back boiler CH system - Advice needed.

    Thanks that's good to know. Only, the pipe gets hot, like 80-85C hot. Im concerned about the plastics in the Magna clean not handling the heat over time.

    Gravity based back boiler CH system - Advice needed.

    Hi again guys, further to my previous queries, I'm trying to work out the Boiler return on my system with the aim of checking if I have space to fit a Magnaclean Atom. In the attached picture, Blue is Cold pipes (main feed to loft tank + main feed to electric shower, I think), Teal is a pipe...

    Gravity based back boiler CH system - Advice needed.

    @Hugh Jaleak - thanks for the feedback. I'm getting schooled in a hurry, appreciated. At present, apart from the pump failing for the second time in my ownership, and the rads and pump hitting 80C+, there isn't any functional issue with any part of the system. With that said, I have replaced...

    Gravity based back boiler CH system - Advice needed.

    I'm rather embarrassed to report that the HW Tank stat was set to 50c! I never bothered to look or noticed this before and truth be told I didn't know anything about the risk of Legionella from a HW tank until 24hours ago. Now I've set it to 60C, but I'm wondering if the HW tank supply is...

    Gravity based back boiler CH system - Advice needed.

    Thanks for that. It is appreciated. So plan of action. 1. Check the thermostat setting on the hot water tank, must be 60C+ 2. Wind the Boiler thermostat knob anti-clockwise a bit (a quarter turn?) and see if the temp drops a bit at the pump (which is the hottest part of the system I measured...

    Gravity based back boiler CH system - Advice needed.

    What do you mean by Airjec? - I don't understand what this means, or what I can do about it if required to do maintenance. Its a 1960's Council house build, which I purchased from the previous owners a few years ago. I'm betting this is the original heating system from the 60's. I replaced the...

    Wow, thanks for all the responses guys, I wasn't expecting this much feedback so quickly on something this old. My system particulars are: Boiler: GlowWorm Coordinate-G System: reading other posts here and looking at diagrams posted in other threads, I think mine is a C-plan system (there is...

    Gravity based back boiler CH system - Advice needed.

    Hi all, Happy new year. I have a gravity back boiler CH and hot water system and I need a bit of advice.... I called out a Gas contractor last September to service the boiler. He faced issues with getting the boiler going again after switching it off to do the maintenance. In doing so several...
