Last month, we discussed the role of buffer tanks in combination with air-to-water and water-to-water heat pumps that operate as “on/off” devices. The key concept was to turn the heat pump on and off based on changes in the buffer tank temperatures and not based on thermostats calling for heat.

Last month, the Biden-Harris Administration announced it is proposing the first-ever national drinking water standard for six per- and polyfluoroalkyl substances (PFAS). The proposal, if finalized, would regulate PFOA and PFOS as individual contaminants, and will regulate four other PFAS — PFNA, PFHxS, PFBS and GenX Chemicals — as a mixture.

Recent LinkedIn studies show that more than half of the workforce is open to exploring new employment opportunities. That means there is a good chance that as you read this article, you have people assessing their employment options in your company.

It was August 2019 when I was last published in PM magazine. I wrote about the failure of cast iron soil pipe, which now has customers often waiting two weeks or often longer for a plumber. As the plumbing instructor at Ultimate Technical Academy, the administration is adding classes to accommodate the need for plumbers as quickly as possible.

"According to the ASHRAE HVAC Applications Handbook, the estimated life of an air-to-air heat pump or a rooftop unit is 15 years while a boiler life expectancy is between 24-35 years, depending on the boiler type. So, you will install two heat pumps or rooftop units for every boiler. Where do you think those old units will end up?" I ask the class.

Scalding in the home or burns from hot liquids is dangerous to anyone, but is a particular concern to the youngest and oldest Americans. Plumbers are charged with protecting the health of the nation. Thus, plumbers can play a key role in reducing the risk, starting with homeowner education.

Attending trade shows both large and small have always been an integral part of keeping our business abreast of changes within the PHVAC industry. Our employees knew that upon my return, there would be new innovative products joining the tried and true offerings we provided for our customers.

In order to be an effective leader, you need to first understand what leadership actually is. Many people mistakenly believe that leadership is simply overseeing a group or organization. However, there's much more to it than that. Effective leaders possess a number of qualities that allow them to successfully navigate through challenges and inspire others to do the same.

In 1885, when you could still buy a milk cow for $29.70, Albert Butz, a Swiss immigrant living in St. Paul, Minnesota, invented what he called the damper-flapper. He patented it the following year. The flapper opened a damper that allowed outside air to enter a coal-fired home furnace. This increased the oxygen in the furnace and made the fire burn hotter. When the temperature rose to a desired point, the damper closed.

More and more hydronic heating and cooling systems are being designed around air-to-water and water-to-water (geothermal) heat pumps. When the heating distribution system is extensively zoned, a buffer tank is typically installed between the heat pump and that distribution system.
