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.

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...

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...

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...

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...
