Introducing the Fernox Maintenance Solution


Most central heating systems are extremely reliable, however, all mechanical equipment require maintenance from time to time. That's why it's important to call a heating professional to inspect your
heating system once a year. These routine inspections will ensure that issues are spotted as they emerge, and well before they turn into full-blown emergencies. Cleaning the key components of your heating system will help keep systems running efficiently. Comparable to a car, if you don’t change the oil it can seize. Having good maintenance of your heating systems is similar, and good care will extend the life of your tankless hot water heater and boiler.


Your heating specialist will explain the maintenance procedures that are most applicable to your specific system.


Hydronic (Hot Water) Systems


Hydronic heating systems use boilers, rather than furnaces, and should be maintained before heating season starts. Here's how:


  • Check for standing water or other types of leaking
  • Check water pressure and temperature
  • Lubricate the circulating pump
  • Clean the combustion chamber
  • Purge air from the radiators
  • Drain and flush the system every 5 years maximum
  • Clean burners
  • Most important check quality and efficiency of combustion
