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 John Kopf eventually gets around to designing and building his own house, he will go with hydronic heat instead of a more traditional forced air system. Kopf knows a thing or two about heating, having spent more than 20 years in the industry. He currently serves as boiler product manager for Navien.

Over the years, our office has received requests for design assistance for systems involving two hydronic heat sources, each in different buildings, where the expectation is to have either heat source supply heat to either building.

After being contacted by the general contractor, we met on site to go over the possibility of installing a snowmelt system for the more than 2,000-square-feet of sidewalks, which also included two ADA-sloped approaches to the grand entrance, a wide sweeping brick stairway and the landing pads outside the grand entrance.

Water is the “life-blood” of hydronic systems. Its chemical characteristics can make the difference between a system that lasts for decades versus one that develops expensive corrosion issues within months of commissioning.

Water quality. If you haven’t spent a good deal of time thinking about it and the impact it has on your hydronic heating system, think again.

Uponor’s biannual convention in Las Vegas continues to be a major draw for the PHCP industry.

When designing hydronic circuits, most of us focus on what’s necessary for that circuit to absorb thermal energy at a heat source, carry it along like a conveyor belt and release that energy at one or more heat emitters.

Pilot-plumber Greg Hunsicker goes above and beyond for a family in need.

The math associated with some of our assumptions can lead to incorrect conclusions.
