There’s a saying in the environmental health and safety industry: “There are no accidents.” Basically, the idea is this that all accidents can be avoided.

On a military base in east-central Alaska — where the average winter temperature is 16° F with lows that fall well below minus 50° at times — dependable, low-maintenance winter heating systems are critical for the active-duty military families and Department of Defense civilians who live on the military post.

Water is the life-blood of hydronic systems. Just as we strive to maintain the health of our own circulatory systems, it’s important to maintain the health of the water-based solutions that circulate through the hydronic systems we construct and maintain.

At the end of the day, if you want your business to be truly successful, you need to look after your people — that means giving them the tools to succeed, the resources they need to perform and a clear vision of where they’re going.

Businesses are facing major changes in the way they operate and the way they interact with clients, partners and suppliers. These changes, which are rooted in uncertainty, often challenge our business confidence as leaders at the highest level.

The service industry needs both data and emotion. Emotional intelligence is crucial to balance them. Strive to understand the 'why' behind the numbers, promote emotional intelligence, pilot programs, open feedback channels, and keep an eye on the long game.

There’s no doubt about it, concern over water quality is becoming more prevalent. One just had to walk the trade show floor during the 2022 Kitchen & Bath Industry Show (KBIS) to see plenty of new water filtration and management systems, some even dispensing sparkling water by user preference.

Plumbing & Mechanical and PM Engineer Chief Editor Nicole Krawcke sits down with Legionella expert Dr. Janet Stout, PhD, to discuss best practice strategies in the plumbing industry for implementing risk assessments and Water Management Programs.

Check out the ways in which these companies are getting involved, making changes and learn how you can too.

Water scarcity is a growing issue globally. Some regions are adopting water reuse and rainwater capture solutions. Onsite water reuse can help save money, reduce water demands, and manage stormwater flows. With onsite water reuse, you can reuse up to 95% of a building's wastewater.

Builders often overlook local water chemistry when selecting materials. Water chemistry and plumbing materials require more attention.

Appendix M of the IAPMO Uniform Plumbing Code, or the Water Demand Calculator, was integrated into the California Plumbing Code on July 1. It provides a new method for sizing water pipes in residential buildings. For Villara Corp., a leading plumbing and HVAC contractor in Northern California, it remains business as usual, having used the calculator for over five years to construct over 5,000 single-family homes.

With user-friendly plug-in installation and energy-saving thermostat control, the system is ideal for preventing ice from forming inside 3/4-inch to 6-inch diameter water lines in temperatures below -40°F (-40° C).

The simplicity of the patented Centra-lok design is also intended to offer a cost-effective vinyl-by-vinyl containment system for commercial, industrial, and municipal water and wastewater applications.

Recognizing that pipe joints are the most common source of premature leaks and system failures, IPEX has designed Centra-lok to minimize maintenance, repair and installation costs.

It’s not often that a 27-year-old decides to start his own contracting company, but in the case of Ryan Osterkamp, that’s exactly what happened.

Integrated Dynamic Control (IDC) is a PC-based intelligent control system delivering optimized comfort and maximized efficiency by coordinating HVAC, IAQ and hydronic systems in one control.

Radiant heating and cooling systems are not new to the North American market, but there’s a strong trend toward incorporating both, especially for tightly controlled environments such as commercial spaces.

MrPEX’s Integrated Dynamic Control (IDC) is a PC-based intelligent control system which delivers optimized comfort and maximized efficiency.

Smatrix Pulse is the industry’s first multizone wireless control system for both radiant heating as well as forced-air heating and cooling.

Boiler systems are essential for residential heating and hot water. Their efficiency and longevity depend on good water quality. Poor water quality causes corrosion, scale buildup, and higher costs. Maintaining high water quality ensures smooth operation and durability.

In 1988, Holland, Michigan’s downtown needed revitalization. Merchants were leaving for a nearby indoor mall. Local industrialist Ed Prince proposed installing a snow-melt system for the streets and sidewalks after seeing a similar system in Europe.

The owner asked for a bid to replace her 35-year-old cast iron boiler which was still operating. She had two requirements: Redundancy in the event of a boiler malfunction and lower fuel costs for the building.

When troubleshooting a hydronic system, the piping layout is often confusing. To understand the system, I sometimes sketch the piping to help me visualize the flow of water. 

It was such a simple project; replace the old cast iron boiler with a new condensing boiler. You knocked it out in a few days. 

Troubleshooting hydronic systems can be challenging, as the pipes are hidden behind walls. Your imagination has to help you “see” the routing of the piping. 

Integrated Dynamic Control (IDC) is a PC-based intelligent control system which delivers optimized comfort and maximized efficiency by coordinating HVAC, indoor air quality and hydronic systems in one control. 

REHAU announces the addition of CPVC and copper press adapters to their proprietary EVERLOC+ compression-sleeve fitting system.

Featuring built-in intelligence and a sustainable-forward, compact design, the e-1510X Smart Pump marries the proven efficiency of the e-1510 end-suction pump with Xylem’s innovative hydrovar X Smart Motor.

Although I’ve worked with hydronic heating for four decades and designed systems around just about every possible heat source, I would be hard-pressed to predict what might be available as hydronic heat sources 25 years from now. 

Several years ago, I had the opportunity of visiting the Mostra Convegno Expocomfort show in Milan, Italy. It ranks right up there with the famous ISH show in Frankfurt, Germany, as a “bucket list” event for those who are passionate about hydronic heating and plumbing.

The overall objective was to create a complete HVAC system, rather than just a heating + cooling system. The system would provide space heating, cooling, domestic hot water, and fresh air ventilation.

Find out about piping options for retrofitting an air-to-water heat pump into an existing hydronic system.

I’ve written many PM columns discussing how air-to-water and geothermal water-to-water heat pumps can be combined with hydronic delivery systems to deliver efficiency AND superior comfort. This combination is a great solution for many consumers.

I attended a conference hosted by the Building Performance Association and presented on air-to-water heat pump systems. Many professionals were interested in heat pumps, especially ductless air-to-air systems. One person mentioned the difficulty of finding qualified installers for air-to-water heat pumps and noted the higher cost compared to ductless air-to-air systems.

In 1986, I installed a 1.5-ton geothermal heat pump in my home using two 500-foot horizontal HDPE earth loops. After digging a trench, I connected the loops to the pump and opted for a 2 HP swimming pool pump to fill and flush the system, as a garden hose couldn't provide the needed flow rate.
