Guttering heat shield

[TomLane]

Going to be installing some new guttering for a customer & they've a flue from the boiler that vents close to the guttering. They've had a GSR from Worcester B. tell them that there is such a product available that will provide a shield to the guttering whilst not to block the flue.

Anyone heard of anything like this?

I know that the flue obviously shouldn't be so close to the guttering (not sure of exact measurement) but I just want to be able to advise them as to whether this heat deflector does exist before I tell them they're boiler needs replacing.

closure plate bend it to suit

Even the main gas man at my college was bending a bit of metal to use as a heat shield for such a purpose. And he's an investigator into gas incidents so not one to do things wrong.

Tom post a picture ! New boilers will not damage guttering as temp of flue gases is about 50 degrees C

200mm for a fanned flue. I just squeezed one in yesterday so I had to check!

on most standard efficiency boilers can go down to 75mm if mi,s allow on most HE boilers

Haven't got a picture unfortunately. It's a relatively old WB & it's the square terminal very similar to this one.
(Not sure of the correct name for them)

balanced flue terminal,closure plate will do the job

I've got to go there tomorrow to drop a quote off for some other work so I will try & get a picture & measurements just out of interest.

Drop a price for a new boiler too and I will fit it for you Tom

 

[TomLane]

Already told them they need it replaced. Problems with diverter valve & pressure too so they've been told but they've said until it actually breaks down they'll leave it!

The logic of some people is baffling.

I'm only doing the guttering as there's parts of it that have been causing damp inside the house!!

BS 5440-1 shows a minimum dimension of 300mm from a balanced flue terminal under a plastic gutter, but it is acceptable to fit a heat shield 1m long over the plastic gutter, easiest thing to use I s thin aluminium sheet formed to suit
