Regular maintenance is a legal requirement. It is also
essential for the safety, efficiency and durability of the
boiler. Proper maintenance keeps consumption and
emissions down, and ensures that the boiler continues to
operate reliably over time.
Have your boiler serviced either by
THERMITAL
’s
Technical Assistance Service or by a qualified heating
engineer.
Analyse the combustion fumes before commencing any
maintenance. The results of fume analysis can give a
clear idea of what servicing or repairs are needed.
