We are proud to present the fourth of five eBooks specifically for the hydronics market. Brought to you by Plumbing & Mechanical, PM Engineer and Supply House Times, this FREE eBook is a collection of columns and articles from John Siegenthaler, a well-respected hydronics expert.

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.

Apartments and condominiums provide homes to families with different comfort preferences and different attitudes on energy use.

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.

The U.S. geothermal heat pump industry was breaking out the champagne on Feb. 9, 2018.  That’s the day President Donald Trump signed the Bipartisan Budget Act of 2018, a bill that boosted government spending by hundreds of billions of dollars.

We are proud to present the third of five eBooks specifically for the hydronics and radiant heating/cooling market. Brought to you by Plumbing & Mechanical, PM Engineer and Supply House Times, this eBook is a collection of columns and articles from John Siegenthaler, P.E., a well-respected hydronics expert and longtime columnist for PM, pme and Supply House Times.

Have you noticed the strong interest in cold-climate air-source heat pumps over the last couple of years?

An installer was asked to include an air-to-water heat pump into a low-temperature radiant panel heating system supplied by a mod/con boiler.

One of the “delights” of designing hydronic systems is looking for synergistic opportunities, where one device provides multiple functions or benefits that would otherwise require two or more separate devices.
