Hi,It's difficult to say ,especially when no smell in hot water mode .I would say a visit to diagnose the cause is a must . Regards
Smell when heating turned on
Posted by Hong-Tin Lau, on
Have a combi boiler, which works fine when only hot water is turned on. However, when heating is activated we're getting a horrid smell. Kind of sewage, eggy smell.
What is causing this?
