I have a heating system comprised of skirting radiators that form part of a loop from the boiler, round the house and back. Some rooms get warmer than others despite closing off the skirting radiator heat vent. They are designed to house the finned heating pipe and a return pipe, the latter...
What is the boiler flow temperature required to flag this 2965 fault code?.
This, I believe, is a blocking code that trips the burner but when/if it resets. the burner will refire without any boiler reset?
If this fault code is up while in CH mode and there is a demand for HW, will the boiler...
Hi, I was hoping to replace an old system boiler with a Vaillant Ecotec Exclusive 627 system boiler, thats the one with the diverter valve so no need for zone valves, controling it with a V-Smart and a VR10. I've spoken to Vaillant Tech and they said you cannot use the VR10 with a vented...
I have a Worcester Greenstar gas boiler circa 2017. There has been a noise coming from the boiler which resembles running water, I have checked the system pressure at 1.5bar and the relief valve but the noise persists unless a hot water tap in the house is opened then it stops for a period of...
Got a replacement combination boiler, less that 1 year old.
Noticed some water from the connection pictured. Can't see what is it from the manuals, possibly a rainwater drain?
Was told by the person from Vaillant that it was an A A V (auto air vent), but she didn't sound too certain!
Can...
Hiya - posting in this forum as I'm guessing this relates to my neighbour above's boiler, but I may be wrong so please say if so.
Basically the attached pix and vids show my issue. I've got a small copper-looking pipe protruding from the wall above my rear tenement bedroom. It's dripping almost...
I have an old Modena 80 E combi boiler that is randomly short cycling on windy days. The burner goes out and re-ignites within a few seconds and continues to burn for between five and forty seconds before stopping again. Under normal conditions the boiler works fine but as soon as it gusts over...

Hi all,
My pressure is stable at 1.5 when the boiler is off, but if I switch it on, the pressure rises as expected, but once switched off it will only drop back down to 1.6. This happens exach time the heating is switched on so eventually it gradually rises to above 2 bar and I have to drain...
Copper pipes, I think its fair to say, is not what it used to be, the copper is getting thin while the cost is going up. Meanwhile, plastic Pushfit seems to be getting better and better, cost and convenience was always better, but now the quality is to, have we reached a stage where plastic will...
Morning all,
My Vallient Ecotec Plus 831 is stored in the loft and is connected to Hive. It is coming on randomly at various times of the day, but particularly middle of the night, and staying on until I manually turn the boiler off. Hive schedule is switched off but still comes on.
Had an...
Hello All,
I was hoping you could help with a potential boiler build query for my father. He has recently had a new boiler installed via British Gas (valiant brand). The external boiler flue seems excessively tall, proving to be somewhat of an eye sore (please see pictures attached). I know it...
What is/should be the switching differential in the above, installed in a Heatrae Sadia unvented HW Cylinder, set to 60C. Can't find anything in the spec sheet re this.
I have a greenstar 35cdi combi boiler that when the thermostat calls for heat. It will fire up heat to temp and then drop down to 41* on the boiler display and then kick back in again.
I have checked all wiring and the zone valves. What else could it be? anyone seen this before
Hi all - can someone explain what the two black levers are in this picture? Are they for putting more pressure in the heating system? I have a Megaflow Eco Systemfit Unvented Cylinder.
Hi,
The outlet of all my radiators are at 55°C, but the boiler keep showing the Return Temperature is 60°C (and keep raising at 1°C/min rate)
Also the flow temperature keeps going up above the set point and when it reaches +5°C above the set point, the boiler shuts down (even before the room...
Oil boiler (now~15 years old) unvented system with 17 radiators. We moved in 5 years ago and I had to keep bleeding the same radiator. The bleed gas could be burned with a blue flame and the water was acidic (pH 5.5).
Since then system has been chemically flushed (it was not too bad) and the...
I need some help and advice with a boiler issue. We have F29 and then F29 appearing on our new boiler. This happened after few days where water was dripping from the condensation pipe. Our regular gas engineer(who installed the boiler) was not available and will be in a couple of days. The...

// Had an E1 error code, repressurised via with filling loop
// Boiler fires but now the pressure runs up from 1.5 mark in the green up to 2.5 in the red then flicks off.

I reckon if I did a survey of 100 heating engineers, asking what would they recommend for heating a granny annexe being built onto the side of my house, in place of the garage, most would give me a suggestion to put in a) an extension to the existing boiler rad circuit & electric water heaters...
Hi,
I have a Vailant EcoTec Boiler with a Megaflo. These are controlled by a Honeywell controller. I have one 3 port diverter, where one of the outputs goes to a 2 port diverter prior to the Megaflo (I believe this is some safety feature).
I have run into an intermittent problem where some...
