Water is our business, so we take every opportunity to remind colleagues and friends of its importance. March 18-22 is National Fix a Leak week. An entire week is set aside to celebrate water by reminding us not to waste it. Those little drips add up to a significant amount of money and wasted resources. Keep in mind how much energy goes into moving water and how much water goes into making energy. Save water and you save energy. It can be easy being green!!
The idea of replacing the boilers in an existing central energy plant can be daunting. This is very high capacity, very large, and very pricey equipment. The renovation can take a long time and require extensive modifications to the existing mechanical room. The logistics of getting the old equipment out and getting the new in is a full project by itself.
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
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.
Let’s face it, we live in a world of instantaneous gratification. We want it now. We want it now and we don’t want to wait. We want it now and we don’t want to go any further than our finger tips to get it. In today’s IoT world, everything is immediate.
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.
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.
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.

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….
