Specializing in Steam & Hot Water Boilers Since 1956


We have specialized in installing, servicing, and maintaining boiler controls since 1956. We understand controls play a crucial role in the efficient and safe operation of boilers.

Steam Averaging Controls:

Steam Averaging controls are specialized equipment designed to maximize the comfort and efficiency of a steam system in a multi-unit building. The control can take an average of multiple in-unit sensors and create a proper call for heat. The ability to drop sensors from the average creates less temperature variance throughout a building and avoids false readings in the average. Below are

  • Outdoor Temperature Sensors: The outdoor sensor makes multiple control features possible. Outdoor override is a standard feature that restricts the boiler from turning on when the outside temperature exceeds the prescribed set point. Some controls also have a cold weather boost setting for extreme conditions to anticipate the demand and maintain indoor temperature.
  • Indoor Temperature Sensors: temperature sensors are strategically placed throughout the property to monitor the temperature in different areas. These sensors provide feedback to the control system. That feedback allows the control to create an average and drop outlier sensors. This allows for the most efficient and balanced system operation in all weather conditions.
  • Day/Night Schedule: The control system can create multiple schedules for different target set points throughout the day and night hours.
  • Internet Functionality: Many controls can have Internet or Wi-Fi functionality and allow remote access via an app or portal. This allows for alerts of potential outages or remote management of set points,

  • Benefits of Boiler Averaging Control:
    • Energy Savings: The boiler averaging control’s features allow for the most efficient steam system possible, utilizing averaging, outdoor override, and schedules to provide tangible results in gas usage and comfort.
    • Improved Comfort: Boiler Averaging controls provide consistency and balance to the boiler system, making the indoor climate as comfortable and efficient as possible.
    • Extended Equipment Life: Operating the boiler via control instead of a time clock saves the boiler from running unnecessary cycles. It also reduces wear and tear on the system, potentially extending its lifespan.



Outdoor Reset Controls:
Outdoor reset control is a sophisticated method used in boilers to optimize heating system efficiency by adjusting the boiler water temperature based on the outdoor temperature. Here’s how it works:

Outdoor Temperature Sensing: The outdoor reset control system relies on sensors to monitor the outdoor temperature continuously. This sensor is typically located outside the building or in a location that accurately reflects the outdoor conditions.

  • Target Water Temperature Curve: The control system uses a pre-programmed or dynamically adjusted curve that correlates outdoor temperature to the desired boiler water temperature. As the outdoor temperature changes, the target water temperature adjusts accordingly.
  • Modulating Boiler Operation: With the target water temperature determined based on the outdoor conditions, the control system modulates the operation of the boiler to achieve this target. When the outdoor temperature is mild, the system reduces the boiler water temperature; it increases the water temperature when it’s colder outside.
  • Feedback Loop: The control system continuously monitors the indoor temperature and compares it to the desired setpoint. If the indoor temperature deviates from the setpoint, the control system adjusts the boiler water temperature accordingly to maintain comfort levels within the building.

Benefits of Outdoor Reset Controls:

  • Energy Savings: By adjusting the boiler water temperature based on outdoor conditions, the system operates more efficiently, reducing fuel consumption and energy costs.
  • Improved Comfort: Outdoor reset control ensures more consistent indoor temperatures by dynamically adjusting heating output in response to changes in outdoor conditions.
  • Extended Equipment Life: Operating the boiler at lower temperatures during milder weather reduces wear and tear on the system, potentially extending its lifespan.

Water Feed Control: Also known as an automatic feeder, it sends water to the boiler in conditions when it is low on water. On a steam boiler, this occurs when the water level goes below the primary low water cutoff. The low water cutoff signals to the feeder that the boiler is low on water. The feeder then opens a valve to allow water to enter the boiler until the float or probe senses the proper water level, shutting off the feeder.


Water Feed Control Benefits:

  • Flood Prevention: Modern feeders have multiple safeguards to prevent overfilling. They can be programmed with a delay in scenarios where it may take time for the condensate to return to the boiler. They can also be programmed to lock out if the meter feeds over a certain number of gallons consecutively without receiving a signal that the system is satisfied.
  • Leak Protection: The control has a built-in water meter that allows feed water monitoring. Some buildings have underground piping leaks that do not allow the steam to return to the boiler as condensate. When the boiler continuously feeds fresh water, it leads to more lime and deposits that cause erosion in the boiler and the system. Monitoring water usage is a great way to ensure a tight and efficient system.
