Westinghouse Air Brake Technologies (WAB) Reaches New 52-Week Low at $65.45 | Silent Ventilation Fan

Multinational company Carel extends its portfolio by acquiring Italian heat exchanger manufacturer Recuperator SpA.

“Additional measures have been undertaken to ensure that the needs of inmates and staff are being addressed, including providing increased access to the outside air court for fresh air and bringing in coolers of chilled water to supplement the existing tap water that is already available,” Fairbairn said. “Those with individual health concerns should be assessed by our on-site medical staff to determine if any additional precautions may be needed.”

A common misconception in the building industry is that a house “needs to breathe.” If a house is too tight, it could lead to mold and moisture problems. Typically, the older the house is, the leakier it is. And the leakier it is, the less likely it is to have mold and moisture problems. What’s the trade-off? A drafty, uncomfortable house, with high heating bills. Newer houses are much more airtight. This means that there is less uncontrolled air leakage and heat loss. Without mechanical ventilation, tighter houses could develop moisture and air quality issues. The tighter the house, the more important mechanical ventilation becomes. A more accurate statement created by the building science community is “Build tight, ventilate right.”

A cracked heat exchanger might, under the right conditions, create elevated levels of CO, but this is not typical. If a furnace has a cracked heat exchanger, the combustion gases can mix with the household air. It’s usually just a little bit, but this is still unacceptable, and it means the furnace or heat exchanger should be replaced. More on that topic here: Heat Exchanger Cracks and Carbon Monoxide Myths.

Ventilation is a significant part of the of the total space heating load, particularly in new-build schools with low fabric heat losses. Heating incoming air can be between 20% and 50% of a building’s thermal load and should be reduced as far as practically possible. Additional outside air entering the building in the winter above the minimum required to achieve good air quality is wasted energy.

One day in 2012, Audrey Keunebrock and Jaouad Zemmouri were on the French Riviera, looking out at the Mediterranean. Zemmouri, a research scientist, started thinking about the huge quantity of solar heat trapped in the sea, and wondered: how could that energy be transferred from water into air? Two years of research resulted in the Terrao heat exchanger, an innovative way to recycle thermal energy.

The researchers are now working on adding another protein to the plants that would remove formaldehyde from the air, according to the study, published in the journal Environmental Science & Technology.

No price or repair negotiations should take place regarding conditions that were known prior to the home inspection. If a condition is readily visible or apparent, it’s not something that was “discovered” during the home inspection. A few examples of known conditions include:

Polaris’ and others’ inability to design an ROV that can go fast without burning up itself and its passengers has created a whole aftermarket for accessories that mitigate heat accumulation –which owners don’t discover they need until they experience the problem themselves. One 2016 article for UTV enthusiasts introduced six products to keep a RZR Turbo from overheating:

While the Minnesota Fuel Gas Code has specific installation requirements for gas water heaters, just following all of these rules doesn’t mean a water heater will draft properly.  Even with a proper installation, there are three common home improvements that can cause problems with existing water heaters.
