AHRI Announces Specification Change for Infrared Heaters

Posted by Andy Hayes on Dec 11, 2018 3:26:05 PM

By now, we all know the advantages of using infrared heating for those special areas in designs with large open areas like warehouses, distribution centers, and maintenance facilities.  Areas with multiple open doors and large open spaces are especially good candidates for infrared (IR) heating. 

The top benefits of IR heating are:

  • Like the sun, infrared heats objects via energy waves
  • IR is not dependent on heating the air to provide comfort
  • It is one of the simplest and most effective forms of heating

Introduction to Magnetic Bearing Technology

Posted by Andy Hayes on Nov 30, 2018 10:14:04 AM

Conventional commuter trains are generally limited to a top speed of 60 miles per hour.  The train speed is limited by the track condition, curvature, and elevation changes.  It takes a lot of energy to move that big, heavy equipment up and down the track.  Additionally, the train must overcome rolling resistance between the train wheels and the track to get to higher speeds.

HVAC System Contamination: Solutions to a Dirty Problem

Posted by Andy Hayes on May 8, 2018 3:04:57 PM

Air and dirt are big-time attackers of closed-loop HVAC systems. Heating and cooling your system water can be more difficult with air and dirt causing problems and impeding the flow. Figuring out that your system is contaminated isn't too difficult, especially considering that few (if any) are 100% closed. One indication of a problem is noise in your pipes, terminal units and other equipment. Inadequate flow can cause problems like cavitation. You may hear moans, hammering sounds or even a high-pitch resonance. Increased operating costs could become problematic with a reduced ability to transfer energy. Systems with air and dirt contamination face corrosion and flow restriction and blockage. That's a problem.

Three System Benefits of High Efficiency Burners

Posted by Andy Hayes on Feb 27, 2018 3:51:53 PM

System design is a critical element of system efficiency. The hydronic heating system must be designed correctly to take full advantage of a high efficiency high turndown boiler. It makes sense that a high efficiency boiler will never perform at a high level in a system designed for an atmospheric boiler. The physics is just against performance.

Are You Handling Exhaust and Condensate in Building Mechanical Rooms?

Posted by Andy Hayes on Dec 1, 2017 9:37:15 AM

As the days get colder you might get a chance to see science in action. Mornings are getting colder this time of year. One morning soon on your way to work, you’ll be stopped at a light and see a plume of visible ‘smoke’ coming out of the exhaust pipes on the cars in front of you. Assuming those cars are all running correctly and not burning oil, that faint white smoke is actually water vapor from condensing combustion gases. Let this ‘smoke’ be a vision cue for you to remember to think about exhaust.

10 Scary Things in Your HVAC Equipment Room

Posted by Andy Hayes on Oct 25, 2017 10:35:02 AM

It may be the scariest place in your building. More dreaded than the hut at Camp Crystal Lake, scarier than that little girl with the vacant eyes and lank hair, worse than any house of horrors. The groans, the slamming sounds, the darkness….

Why Oxygen Levels Matter in High Efficiency Boilers

Posted by Andy Hayes on Oct 10, 2017 8:56:33 AM

Oxygen matters.  Every living organism on earth needs it in one form or another.  While a high efficiency condensing boiler isn’t necessarily a living thing, it does work in a system that requires appropriate amounts of oxygen to operate at optimum levels.  In that way, high efficiency boilers are a lot like you and me.

So, how does it work?
