Some hydronic system designers cling to certain system piping configurations — even when existing projects using those configurations have produced problems.

Anyone who says they wouldn’t change a thing on the hydronic systems they’ve designed or installed over the last decade is either so oblivious to changes in technology that they don’t know any better, so egotistical they can’t accept that improvement of their work is possible, or so foolish they don’t care what they’re missing out on.

Part of running any business is looking ahead and trying to read the “tea leaves” that are relevant to that business. 

Modern panel radiators are one of my favorite heat emitters.

Few would argue that fin-tube baseboard was the “flagship” heat emitter in North American hydronic heating systems through much of the 20th century. 

I recently designed a system for my daughter’s new home with a water-to-water geothermal heat pump as its main heat source. 

Ask a heating pro about the energy used by the systems they design or install.

One of the benefits of modern hydronic heating is the ability to use multiple types of heat emitters in the same system.

This was quite a year for me on the home front. On fairly short notice, my wife and I found out that our daughter Heidi and her husband Andy would be building a house about 500 feet down the road from us.
