Frequently Asked Questions
How often should I service my Crown boiler?
Crown boilers should be serviced annually before the heating season. This includes cleaning the heat exchanger, checking combustion efficiency, inspecting safety controls, and testing water quality. Cast iron boilers may require additional cleaning of the flue passages to maintain efficiency.
What is the typical lifespan of a Crown boiler?
Crown cast iron boilers typically last 20-30 years with proper maintenance, while their condensing models can last 15-20 years. Regular annual maintenance, proper water treatment, and prompt repairs can significantly extend the lifespan of your Crown boiler.
Why is my Crown boiler making banging noises?
Banging noises (water hammer) in Crown boilers are often caused by trapped air, sediment buildup, or improper water pH levels. For steam systems, it could indicate water level issues or improper pitch of steam pipes. Professional cleaning and water treatment usually resolve these issues.
Can my old Crown boiler be upgraded to high-efficiency?
While you cannot convert an atmospheric Crown boiler to condensing technology, you can improve efficiency with outdoor reset controls, proper insulation, and regular maintenance. For maximum efficiency gains, replacing with a Crown Phantom condensing boiler is recommended.
