As many companies adopt growth-oriented language, it’s important to explore the tactical strategies behind it. Key benchmarks to consider include: What roles do we need to fill in the next few years? How do we retain our experienced employees? Who is our ideal customer and how many will we have in three years? What are our projected revenues in 5 and 10 years? Are our plans aligned with healthy gross and EBITDA margins?

Rethinking tankless: fact over fiction

Debunking misconceptions about cost, cold climates, and high-demand performance.

Many people still hesitate when they hear the phrase “tankless water heater.” The myths run deep: they won’t work in cold climates, they’re too expensive, they can’t keep up with demand. These misconceptions are fueled by early limitations in the technology and years of hearsay passed along between homeowners – and even some tradespeople.

Using ratios to measure, compare and improve HVAC systems

Relating to ratios

Many of the ratios used in the HVAC industry are just some “desirable output” quantity divided by the “necessary input” quantity. One example is the coefficient of performance (COP) of a heat pump. The desirable output quantity is Btu/hr of heat output. The necessary input quantity is the electrical input power needed to operate the heat pump. The latter is typically measured in watts or kilowatts.

Hindsight - From complex loops to clean headers: simplifying for reliability

Around 25 years ago, I developed a design that sends high-temperature water to a remote manifold for low-temperature floor heating, mixing it with returning water to achieve the optimal supply temperature, regulated by a variable speed pump. Can you identify a problem with this approach or propose a better one?

Smarter solutions for overcoming wastewater management challenges

Learn how advanced centrifugal grinder pump design addresses common performance and maintenance hurdles.
Andy Freberg

The most efficient grinder pump requires no maintenance, manages solids without clogging, and supports various wastewater systems by preventing settling and handling modern “flushable” products.

Boiler efficiency starts with water chemistry

Why testing before installation matters.
Steve Wieland
October 10, 2025

Water chemistry significantly affects boilers, with scale buildup as small as one-sixteenth of an inch causing a 20 percent loss in heating efficiency and leading to corrosion, leaks, and potential boiler failure. Analyzing water chemistry beforehand is crucial for identifying necessary solutions and ensuring long-term performance.

Voices of the future: Apprentices reflect on learning and leadership

PHCC Foundation expands training to meet contractors’ evolving needs.

Apprenticeship has long been the heartbeat of the plumbing and HVAC trades. But for today’s apprentices, training looks different than it did for their mentors and parents. With new online programs, flexible learning schedules, and updated curriculum that reflects the latest industry standards, apprentices are able to gain both the technical “booksmarts” and the on-the-job confidence needed to thrive.

How mismatched loads in a dual-temperature heat pump system can limit performance

At a supply water temperature of 103 ºF, the heating capacity of the heat pump is the same as the total heat dissipation ability of the distribution system. That’s where this system achieves thermal equilibrium. The floor heating zone is fine at this condition, but the output of the air handler is significantly lower than what was planned for based on the assumption that 120 ºF supply water would be available.

Death waits for no one: A lesson in confined spaces

We didn't fully grasp the dangers since no one was OSHA certified or required to comply. It wasn't until one employee reported feeling faint while testing backflow preventers in a large underground pit that I recognized the risks. My right-hand man, also the Deputy Chief of the local hazmat team, had expertise in air quality testing.
