It may comes as a surprise to you but Vaillant have made more than one model of combi over the years. I'll make an edusated guess that that you probably have a Turbomax VUW 242 or 282. Black plastic fascia with turquiose knobs and a number of LEDs? Could be a VCW (white enamel case with...

I presume that you refilled the heating after you drained it down ?!? You have probably got an airlock preventing the primary water from going through the coil to heat the HW cylinder. Have a look to see if there are any bleed points, especially in the airing cupboard. Switch the pump...

I have a Keston (C25) in my own home. It is inaudible when in operation, a slight rumble when starting (I must tweak the mixture a little richer to get rid of this). It might be possible to hear something from the flue when it's going full tilt but it doesn't spend very long in that state...

It's possible that the pump ran dry and is now dead. Then the boiler over heated and has locked out I'm not familiar with this model but look around and under to if there is a reset button. might be tucked away underneath.

In my experience doing battle with Potty Pumas. You can check that the main valve is not stuck when you have removed the old wax capsule actuator. If the valve is moving neatly back when you stop pushing then I'd reckon that the very difficult job of exchanging the whole diveter valve can...

This is an unusual fault. Here are some of the things I can think of that might help to get a handle on it: Have you tried the full heat test mode? Pushing the + & - simultaneously this will not modulate and will only cut when the primary flow is at its atop limit (87C ?) You could...

It's not clear to me whether you mean valves that are something like a tap or the ones that join to the hoses. The former are probably leaking from around the spindle and you will probably get them to stop by tightening the nut nearest the handle. The latter are a major source of...

identical Twins (clones) substituting themselves for each other, has been used as part of the plot in quite a few stories. Anyway, assuming I am not being cloned, it seems that I'm owed an invite or two according to an earlier post?

Being cloned would be of some concern to me.

Since I only started posting last w/e The 'lurker' must be someone else. Could you (raden) point me to some of my supposed earlier posts?

The HMO only applies to six or more 'rooms' within a building (but not a purpose built block of flats) the bulk of rented accom both private and social is not like that. I would have thought that CAB would give advise to a tenant who has a scumbag landlord who sees gas safety as optional...

This is a combi boiler. If the boiler works for HW then most of it must be OK. I would look to see what controls are fitted around the house for the heating. Likely there is a time switch in the boiler itself (which you are switching on) also there is (should be) a wall thermostat...

Hi all, I hadn't joined earlier but I have now, at least for this thread. That picture with the hot and cold pipes taking the scenic outdoor route is one of a series taken by me in the course of my work. I was hoping that the pictures would win me a prize in the Eye Spy section...
