Understand Your Boiler
Understanding your boiler means understanding the manufacturer’s recommended parameters. As the creators of the boiler itself, the manufacturer’s recommendations are the best parameters to follow. When your boiler’s readings match up with these parameters, the chances are your boiler is running with peak efficiency.
Check the Fuel Pressure
Always be sure the heat exchanger surface is properly sized and placed. As the rule of thumb goes: if the pressure is higher than it’s designed to be, your boiler’s heat exchanger surface is too small for the unit itself. This issue could cause the overproduction of air and an underproduction of fire, which can severely damage the burn diffuser. If this is the case, contact one of your area’s boiler service companies.
