Hoping someone can offer some advice re housing for Grant external oil fired boiler. We need to replace the housing as it has rusted. Grant tell me they no longer make the housing for our boiler and the only option is to buy a new one, which seems ridiculous as our oil fired service engineers tell us the boiler is fine. Can anyone suggest where we might be able to find a supply of the old housing or how we might get one made? Appreciate advice as we need to get this sorted before the winter.
