Our indoor oil boiler is working normally except suddenly it has started to give off really toxic exhaust fumes. Nobody available for a call out, it has been examined by a layperson who found nothing obvious, any ideas on what to do next?
The seal between the main heat exchanger & the condensing unit may have failed, if boiler is less than 24 months old it should be covered by manufacturers warrenty, (as long as you have had the boiler Serviced at 12 months)
