Whether designing a residential or commercial system, there are several lessons to be learned from Siegenthaler, a.k.a. “Siggy,” including thermal considerations, piping, heat pump technologies, panel radiators, slab heating, controls and ECM circulators in order to provide the ultimate goals: Comfort, high efficiency and a happy customer.

Viega’s seminar centers in Bloomfield, Colorado and Nashua, New Hampshire, held training and examination sessions in January and February for the ASSE 19210 Hydronic Heating and Cooling Installer certification. 

On Oct. 3, 1854, an industrious young man from New Haven, Connecticut, filed U.S. Patent No. 11,747. Stephen J. Gold called his patent “Improvement in Warming Houses by Steam.” 

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.
