An oil boiler should be thoroughly serviced at least once a year.
Under Oftec guidelines, the flexible oil hose to the oil burner in the boiler, should be replaced on
these services. Longlife hoses are available if requested and these are stocked on all of our vans.
To ensure fuel efficiency and safety of your appliance, the fuel nozzle should also be replaced
along with any combustion seals.
If you have a combi boiler, on the water section of this, your expansion vessel pressure will be
checked and topped up if necessary.
