Worcester Bosch Guarantees - Worthless ?

ThisIsWeird

I don't understand the 'flue open to three sides' bit either. Any idea?

But we're talking about a boiler installed in 2019, not 20 years ago. The rules really haven't changed much in the last 4 years.

I don't know of any boilers that don't require a dedicated isolator switch, even back in 2019. The installer would have had to physcially fit the plug (hopefully with a 3A fuse and not 13A), so should have just done it properly then. 

There are set minimum clearances around the flue, which again are normally set out in the manufacturer's installation booklet. Those haven't changed in the last few years. Perhaps the installer thought they would just get away with it. Sounds like it doesn't extend far enough above the roof, or too close to a corner.

Post some photos of the flue showing the context around it.

My boiler doesn't have a dedicated isolation switch, it is on a plug plugged into a socket ( obviously this is also an isolation switch ! ) 

I'm not sure if a socket switch is isolating (at least two-pole). Most likely, not.

You can't get anymore isolated than taking the plug out  

I know and I was addressing the "obviously this is also an isolation switch !" bit.

But that doesn't also isolate any other controls/accessories that are part of the heating system. The point is that the isolator should isolate everything.

The boiler shouldn't have been installed with a plug, it should have been done properly.

And at £4.8k for the boiler install it should have been a gold plated isolator!

Mains supply to the boiler must be through a fused double pole isolator situated next to the appliance. The isolator must have a contact separation of 3mm minimum in all poles.

This is an extract from a WB manual. The above is not a plug in a flex…their manual says ‘you must’…you haven’t! So they can cancel warranty as it’s not fitted to MI’s

As for the flue, without seeing it I’m guessing but may be in different pressure zones.

Post a photo of the flue inside and out - the description given is potentially problematic. Is this how the flue was when the boiler was installed or was it built over later? It could be a safety issue so shouldnt be ignored.

Many thanks for your comments and I have attached some photos of the flue.

I am still awaiting a response from them regarding the isolation switch requirements but I still don't understand how the boiler power supply being plugged in an extension lead can pose a risk to Life or Property.

The photos I posted above was how the engineer installed it back in 2019 and hasn't been altered.

Many thanks but why is it our fault when we used their recommended engineers? The heating engineer company recommended a WB boiler and they were one of their listed installers who will have to service the boiler every year for the next 10 yrs to keep the guarantee valid . For the last 3 years they have serviced the boiler and not said anything about the install being a threat to life and property.

Unplugging the combi boiler from the extension lead powers off the whole CH system off apart from the thermostat which is wireless.

Maybe they don't like the idea of a wall bordering the flue like my photo image above . That means the flue is sheltered 180 degrees by the wall and they would prefer it to be open to 270 degrees like a corner wall.  It's a terraced house so we don't really have an option unless they want the flue to go all the way up towards the roof (with 360 degrees open space).
