What that means for your boiler
- New apartments, boilers still in warranty. A combi fitted in 2016 is inside a 7 to 12 year warranty that almost always needs a yearly service by a registered engineer to stay valid. Keep the service records with the warranty papers.
- Management companies. In a block, the flue terminal and sometimes the gas meter are on common property. Tell us the development when you ring, so the engineer knows what access to ask for.
- Seafront houses. A Victorian terrace in Sandycove or Glasthule has had its heating replaced more than once. The flue route into an old chimney, and the ventilation, are what the engineer checks hardest.
- Oil around Sallynoggin. 10% of homes in Sallynoggin East heat with oil. Oil is an OFTEC technician's job: see oil boiler service.
