Yesterday I had my oil-fired boiler serviced (having only moved into the property a year ago, I discovered yesterday that it probably hadn't been serviced for 5 or 6 years!).
Anyhow, since the service there has been a strong smell of oil (whenever the boiler is hot of course). There is no sign of a leak, so can I safely assume that this is as a result of the service and is maybe any leaked oil being burned off?
Perhaps it could also be because the engineer had to replace a worn flexible pipe?
