Boiler Upgrades and Retrofits

If your installed boiler is in need of an upgrade, this is a good time to consider adding new components and controls to improve efficiency and achieve better total energy savings. Among other things, Webster can recommend the right new burner to reduce excess air and achieve the same burner output using a lower horsepower motor. This combination can save not only on fuel costs, but also – more significantly - on electricity cost.

Webster’s high efficiency burner models

  • JBS(X) Series: High efficiency, low excess air, 40 – 400 BHP range
  • HDS(X) Series: High efficiency, low excess air, low emission, 200 – 1,650 BHP range

Note: (X) designates low and ultra-low NOx models.

Temp-A-Trim® Auto-density trim system

Webster’s exclusive Temp-A-Trim auto air density trim system can be retrofitted on an existing burner of any brand to immediately save up to 3% of fuel and 30% on electricity costs. Temp-A-Trim senses combustion air temperature and automatically varies the fan speed to create a constant air flow mass for combustion. By maintaining optimum fuel/air ratios, you are assured that your burner is operating at maximum efficiency. It also reduces emissions by virtue of reduced fuel consumption.
