    Unvented cylinder not reaching temp when running on boiler

    Here's the thing I refer to as a "gold screw" (and you can see the blue immersion stat dial in the lower left hand corner too):

    Unvented cylinder not reaching temp when running on boiler

    Originally (before I did anything): Blue - 3 Gold - just under 4 Then about 3 days ago (when I started trouble shooting): Blue - I changed to 5 Gold - I didn't know it existed so it stayed at just under 4 At this point, the water was 53.9 when heated by the boiler, but 70 when heated by...

    Unvented cylinder not reaching temp when running on boiler

    They're not on together. I've only used the immersion once, to test it, and I made sure the boiler was off when it was on.

    Unvented cylinder not reaching temp when running on boiler

    So it actually looks like the cylinder has 2 stats - one for the immersion heater (blue dial, numbers 1 - 5), and a second for when it heats from the boiler (gold screw, numbers 1 - 5). Anyway, I turned the blue dial up/down and the valve didn't move. I turned the gold screw to "1" and the...

    Unvented cylinder not reaching temp when running on boiler

    Thanks. Yeah the boiler has a dial for HW and a dial for radiator temp. I was told that the HW dial does nothing when its used as a system boiler, its just there for when its used as a combi? Either way, I have it whacked to max just in case. Yes, this is usually between 74-77 when its...

    Unvented cylinder not reaching temp when running on boiler

    Hi. I've got a Pullin Evolution 250l indirect unvented cylinder, connected to a Vaillant ecotec plus 637 system boiler. It heats from the gas boiler normally, but also has an electric immersion for emergencies. My boiler flow temp is set to 75, the HW dial on the boiler is set to 70, the stat...

    What is this valve and why is it leaking?

    Thanks, I wouldn't attempt taking it apart - if tightening it up doesn't work I would get someone in to replace it. I'm an 'easy fix = DIY but dismantle/reassemble = call the pro's' type of guy when it comes to boilers. But it looks like just tightening it has worked for now - no more dripping...

    What is this valve and why is it leaking?

    This valve is coming from one of the pipes that go directly up into my Valiant Ecotec boiler. It is dripping water, filling that green bowl every 6 hours or so. I assume its a pressure relief valve? But the pressure is not any higher than it always is - The boiler is working fine and pressure...

    Does anyone know what this type of gate is called?

    You're good at this! Its taken me 2 days and countless trips to inspect it, and you figured that out in 5 minutes from a few pics!

    Does anyone know what this type of gate is called?

    I think you're right! I've just been back out there peeling away bits of it - I can see its a metal frame gate with the tongue & groove planks screwed either side (the bread if you like) to blocks of wood in the middle (the 'sandwich filling'). I guess as the metal frame is still good, I could...

    Does anyone know what this type of gate is called?

    I am trying to replace a side gate - what should be a simple task, but I am stumped by the type of gate and fixing I have currently. It is a wooden panelled gate, with 'finished' panels both sides and bracing sandwiched between the two panels. On the hinge side is a metal rail with 2 'eyes'...

    Humming noise - pipe work, or the isolation valves?

    The problem is in one tap AND two toilets so the tap isn't the source, just a symptom.
