When you talk about water scarcity and the lack of clean drinking water, most people think about third-world countries. They don’t realize that there’s a growing threat to clean water right here at home in the United States. Look at the February train derailment in East Palestine, Ohio, where a fire forced the controlled release and burn of toxic chemicals to avoid an explosion. The resulting contamination killed thousands of fish in nearby streams and ignited concerns over soil and water quality.

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.

Can you spot at least six design or installation details that are going to create problems?

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.

Late last year, LIXIL made headlines when it announced the acquisition of Basco, a U.S.-based shower door manufacturing company.

Concealed attic spaces combine some of the most difficult aspects of fire protection design and require carefully tailored fire sprinkler solutions for effectiveness.

Many hydronic installers look for ways to differentiate their work, to craft a specific look — maybe even a “brand” — that resonates with customers. For Fernando Lobo, owner of Fairfield, Connecticut-based 1 Call Services, that unique look begins with the raw material list he builds when sizing a boiler replacement, or new boiler install.

Ray Bramble, along with his sons, Ryan Bramble and Bradley Bramble, are no strangers to franchising. The Brambles converted their family-owned and operated HVAC contracting business to an Aire Serv franchise — a Neighborly company — in 2009, mostly due to a lack of systems in place at the time.
