I've just had my Baxi Boston 2 Boiler serviced, it's 17 years old. The boiler looks in good condition and has been passed as safe to use. However, the heat shield (looks a bit like a narrow wafer biscuit) has broken / fell off the front burner plate. I don't want to buy a new boiler, can parts still be bought for this and if not is it safe to use indefinitely? The service engineer was pushing to invest in a new boiler.
Baxi Boston Heat Shield

sorry not sure which part you mean ? do you mean the heat shield that goes over the gas valve ?
Picture would help. Lots of parts are obsolete for this boiler so you may want to start saving for the inevitable
I think it is this, but only the white insulation board that has dropped off and broken in two. It had been stuck on.

We've tried many sites but all say either obsolete or when we ring they don't have it in stock.
Given that it is just the insulation board (and by the way the gas fitter passed the service), if we can't get the part, could a gas fitter cut a piece of board to the same dimension and stick it on? It seems ridiculous to have to scrap the boiler for such a small piece of insulation board.

Here's a picture

Without that heat shield the metal will overheat, oxidise and burn through in perhaps a year or two.
Being helpful I might agree to cut some from a piece of material from another boiler. But strictly we should not really do that. If I were to fix it then it would be stated as only a temporary solution with the expectation that you would agree to a new boiler within a reasonable period, say within a year.
An engineer seeking to sell you a new boiler is not going to consider doing that though.

Many thanks Tony.
Of course there could be a divorce over the purchase, I'm all for a combi (more room where the tank is now housed as well as other pluses) and my husband hates them with a vengance.

I would never recommend a combi except for a small flat with no more than one bathroom and a maximum of two occupants.
Your husband seems to have good choices on heating. A new cylinder can be fitted in most lofts!

I think he may owe you a pint!
Many thanks again, your comments have been really helpful.

Google a product called Cerafelt. It's an insulating material used in boilers. I've done many repairs in the past exactly like that.
It's an option to replacing an otherwise perfectly good boiler.

Are you saying this temporary repair of yours may cause a potential problem within a year?
Surely if you carry out the repair using the appropriate material then why would a replacement boiler be required within such a short period of time?
Are you not confident of the temporary repair?...if not then why are you suggesting it?
I hope you realise that by questioning Tony he will now have to vanish off this thread and we will never find out why combi's are only suitable for very small flats You're such a troll

I guess manufacturers will be taking heed of your above input and hence lowering central heating output to a max rating of 6kw???
Vaillant obviously read your input and amend their appliances to suit......isn't this what you said a while back??
I've got exactly the same problem as sophiejazz - no spares available for this incredibly simple part, anywhere. There's a picture available of the front of the assembly here:http://www.plumbcenter.co.uk/product/baxi-235381-carrier-insulation-front-door-assembly/. The insulator (same as sophiejazz's pic) is stuck to the back.
So I have to replace a whole boiler for this simple bit of kit, just to get the boiler back in service (BG have disconnected it)!
I would try using the cerafelt, but I'm worried about what adhesive to use - anybody know what would work under these temperature conditions?
