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?

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.

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.

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.

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.

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.

Your energy drives the tone, the pace, and the performance of your team. If your goal is to create a culture where people show up strong, stay accountable, and do work they’re proud of—guess what? That starts with you showing up that way first.

When Brady Jolly steps into the office each morning, he’s carrying more than the responsibility of running a nearly 60-person business. He’s carrying forward the legacy of a company his parents founded back in 1979 — a company that has reinvented itself more than once and is today on a mission to "reimagine how the world experiences home services."

These are common design pitfalls that may seem effective as they are. Review them and identify changes that could enhance the layout.

In 2016, Natural Resources Canada ("NRCan") released Amendment 18 to the Energy Efficiency Regulations, enhancing energy efficiency and water conservation. It introduces new product categories, updates existing requirements, and allows automatic adoption of future U.S. Department of Energy updates.
