Boilers have been around for a very long time - burning everything from wood, oil and natural gas to produce hot water to heat buildings. We have come a long way from an open flame heating a kettle full of water, to very sophisticated burners to the materials used in the boilers to the computer controls to manage the operation of the boilers. Over the many years boilers have drastically changed from a very large, heavy and inefficient piece of equipment to a very highly developed instigate piece of energy efficient equipment. Boilers have come from being 60% to 80% efficient to modern day boilers being 86% to 97% energy efficient. Gone are the days of thick heavy cast iron welded boilers to high tech cast iron that is flexible, to thin copper and stainless steel materials.

The Modern Boiler

The newest styles of boilers are condensing boilers which can produce the highest efficiencies of up to 97% depending on the water temperatures. Once the hot water temperatures drop below 130 0F (55 0C) efficiencies start to climb from 86% up to 97%. In order to produce low water temperatures below 130 0F (55 0C) you must have a system that can use low hot water temperatures and a boiler that can withstand high pH levels within the boiler heat exchanger. There are different burners that a boiler can incorporate in it’s design including atmospheric, fan induced, and different styles of power burners. Each having it’s cost and efficiency benefits. Also different burners will be able to control amount of Nitric Oxide that is being discharged which maybe critical when designing large boilers in high density or sensitive areas.

Maintain your Building's Heating Systems.

Avoid Failures, Downtime, Maintain Cost and Save Energy depending on the age, condition and efficiency of your building's Boilers it may be time to consider replacement.


  • Typical boiler (s) have a life expectancy of 20-30 years.

  • Boiler (s) must be maintained to provide reliable operation with minimum repairs and downtime.

  • Efficiencies can be substantially reduced on older equipment.

  • Maintenance is high on older boiler(s)


  • Fire Tube Boilers

  • Water Tube Boilers

  • Atmospheric

  • Steam


  • High efficiency condensing boilers

  • Mid efficiency copper tube boilers

  • Forced draft boilers

    Significant savings can be achieved had by replacing some or all of the boilers with high efficiency boilers as the lead appliance (s)


  • Review of sizing & boiler selection.

  • Installation design of the new boiler(s).

  • Re-piping for proper flow and efficiency.

  • Pumping with VFD.

  • Upgrade control systems for max efficiency.

  • Proper venting to meet code and increase efficiency and life expectancy.
