Cost Considerations

Initial Investment

Most Economical: Atmospheric
Most Expensive: Durafin™
Mid Range: Power Burner

Good:

  • Virtually maintenance free burners.
  • No Fan Wheel to pull in dust.
  • Minimal electrical consumption.
  • No pre or post purge cycling.
  • Whisper quiet operation.
  • Category 1 rated for use with Type B vent.
  • Less weight and height than power burners.

Be Aware:

  • No Excess air control.
  • Not available in Low NOx.
  • Fuel limitations - Natural Gas/Propane.

The Helpful:

Adding an optional automatic stack damper will greatly increase AFUE (annual fuel use efficiency) by preventing cool ambient air from going up through the heat exchanger and out the stack every time the boiler cycles up. It will also prevent potential tube rupturing freezing air from coming down the stack should the boiler be off during weekends, holidays and other operational down cycles.

Good:

  • Highest non-condensing efficiency.
  • Low NOx burner.
  • Low excess air.
  • Comprehensive factory start up.
  • Low weight and space requirements.
  • Gas and Liquid Fuels.

The Helpful:

  • May qualify for gas company rebate (ask your supplier before purchase).
  • Long term fuel savings payback for initial investment.
  • Especially attractive choice where boilers are also used for reheating in summer and still keeping boiler room temperatures comfortably low.

Good:

  • Excess air control.
  • Wide choice of power burners.
  • Low NOx available.
  • Choice of Gas or Liquid Fuels.

Be Aware:

Power Burner start up and maintenance is more complicated than for atmospherics. These boilers are also available in high efficiency, but note that Durafin™ have higher thermal combustion efficiency. When comparing a high efficiency low NOx power burner fired boiler with a Durafin™, the Durafin™ would be all around better choice.
