Water-to-water heat pumps, supplied from geothermal earth loops, represent a growing sector of the hydronic heat source market. Most current-generation models can produce water temperatures up to about 125° F, perhaps a little higher if you’re willing to push the compressor operating envelope.

As I write this month’s column, I’m attending Plumbing Manufacturer’s International annual Manufacturing Success conference in Louisville, Kentucky. PMI has done a great job with its programming content this year, especially with keynote presenter Andrew Winston, a corporate environmental strategist and author, who discussed how today’s companies are now expected to take a stand against the world’s social and environmental problems — and in doing so, earn a profit.

 While most plumbers may like to think that they’re mostly serving routine maintenance or installation customers, the most common nature of those calls is likely panicked customers with a burst pipe, a backed-up toilet or another emergency that needs a response ASAP.

As anyone in the profession knows, the plumbing industry is rapidly changing. Demand for plumbing services is reaching unprecedented levels, but so too is competition.

Water treatment education and certification for water treatment professionals is a critical part of the mission of the Water Quality Association. The association represents the residential, commercial and industrial water treatment and conditioning industry.

If you rely on search engine marketing for calls, you are putting your company at risk because you are relying on the unreliable. Here are eight steps to wean your company off big tech dependency.

Common sense runs through our veins and helps us avoid idiotic, absurd edicts handed down by well-intentioned, but seriously misguided politicians. The fact is, I’ve always felt that common sense, along with training and knowledge, often handed down from generation to generation, guides our hands and minds as we toil at PHVAC issues.

When faced with decisions, we humans are wired to seek out patterns to help make our choices. However, when we're faced with countless decisions — many of which do not offer a pattern to follow — we tend to develop what's called "decision fatigue."

Most hydronic systems have the boiler running up to 180° F with water returning from the system at 160°. This rarely happens in real life, but it’s the traditional way we do things.

 All boilers that burn hydrocarbon fuels such as natural gas, propane, oil or wood produce water vapor as a byproduct of combustion.
