Radiant & Hydronics

RSS

Heating experts have long touted hydronics as the far superior comfort technology over forced air due to better operational efficiencies and improved comfort. According to Research and Markets, the global hydronic systems market is poised to grow $1.3 billion from 2021-2025, driven by the growing need for energy-efficient cooling and heating systems and increase in construction activities worldwide.

On its face, that makes perfect sense — especially given the severe drought facing so many areas of our country right now. And why not? Greywater draining from bathtubs, showers, lavatory sinks, automatic clothes washers and laundry tubs is not contaminated with fecal matter or urine, so why not use greywater twice?

My iPhone pinged a text: “Hi, Dan. How are you and Marianne, and the family? I’m sorry to bother you. I can’t get my steam heat to go on. I can’t get a plumber to come quickly. I guess they’re busy with the weather. Can I call you later to ask you something about the burner?”

The choice between ∆T and ∆P operation of a circulator has, at times, been the subject of rather “heated” debates. It’s almost as if a few Yankee fans are disputing superior pitching or batting performance with a few Red Sox fans. There appears to be some strong opinions involved.

The university is in the second year of a five-year project to convert its steam systems to low-temperature hot water for more efficient heating across the grounds.

All of my employees and I were sitting in our trucks eating lunch when the OSHA inspectors arrived on the commercial job site, which was a two-story addition to a nursing home. Talk about fear — the other trades and general contractor’s employees about had a coronary!

Some years ago, a wholesaler hired me to do a seminar in a New England hotel for about 100 of his contractor customers. After the seminar, the owner of the company invited me and a bunch of his employees out for a nice dinner. There were about 15 of us.

As building codes and programs such as Energy Star and Passive House require higher degrees of air sealing in new construction, the use of heat recovery ventilation (HRV) is increasing.

If you’re anything like me, the first thing that comes to mind when you think about variable speed circulators is 1970s rock band Supertramp. No? Okay, maybe you’re not like me. Either way, allow me to elucidate.

Customers can be a fickle lot. You do your best for them, but they move on in spite of your fair pricing and Johnny-on-the-spot response times.
