Which is better a catalytic converter or secondary combustian?
Catalytic converters burn more cleanly, but they need to be replaced after a certain number of hours of operation, and they can cost in excess of $150. Regency uses secondary combustion to achieve almost the same low levels of emissions, and our system is guaranteed for as long as you own the appliance. Secondary combustion systems require less maintenance and are more heavy-duty than catalytic converters.
