In this episode of the podcast, we talk to Bill Spohn from TruTech Tools about how TruTech Tools got its start and some of the ways that techs and engineers approach problems differently.

Bill Spohn is a majority owner of TruTech Tools who became invested in the HVAC field in the 1990s. The beginning of TruTech Tools was a milestone in Bill's professional journey. After working at Superior Valve for a few years, Bill moved to Testo. While Americanizing many of Testo's products, Bill Spohn met Jim Bergmann. A German Testo employee advised Jim Bergmann's father to set up an online store for the Testo products and other HVAC tools. That website later became known as TruTech Tools. Jim, his father, and Bill were at the forefront of the new company. Bill contributed to the development of TruTech Tools through his product and marketing knowledge. Since then, TruTech Tools has grown a lot more. Jim Bergmann has since moved on, but he is still friends with Bill and remains a major figure in the instrument development and testing part of the HVAC industry.

Bill considers himself to be an engineer. Unlike technicians, engineers have a deeper level of expertise in the development of tools and products. However, technicians have greater field knowledge and provide valuable feedback for engineers like Bill. Engineers know the math behind their products and how to use those products. However, technicians provide the practical element to tool development. Both technicians and engineers must be humble to work well together, exchange ideas, and technologically progress.

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In today’s podcast, Bryan talks with legendary Hydronics author and trainer Dan Holohan about the history of steam heating and some practical applications of old ideas. Recently, Dan has been working on more novels, having published two of them over the past few months.

Steam heating is a “lost art” nowadays; it has become increasingly uncommon and has been disappearing since the Vietnam War. Many people who understood steam heating either retired or died after the Vietnam War. Many elements of steam heating are difficult to understand or surprising. (For example, steam pressure has a surprising relationship with velocity: low-pressure steam moves through piping much more quickly than high-pressure steam.) So, Dan Holohan is on a mission to revive that knowledge and teach the newer generations about the lost art.

There are many older steam heating systems still operating today, especially in the older large buildings in New York. Dan learned a lot about steam heating when working on these old systems and optimizing them. Most of the time, he optimized those systems by removing unnecessary accessories, not by adding components like steam traps.

Many old boilers used coal as a heat source. Nowadays, many old boilers have been fitted with conversion oil burners with thermostats, but they are still piped for coal. Some systems now have multiple risers or massive vents on the main riser to prevent the thermostats from getting too hot too early and satisfying the thermostat too early. We call that master venting, which reduces pressure and allows steam to move very quickly and efficiently.

Dan also discusses:

The 2-PSI standard
Transportation metaphors for BTUs in steam
Harmful renovations for old boilers
Replacement vs. restoration mindsets
Gaps in steam boiler education
Monopolizing the market if you HAVE the education
Boiler piping and venting
Two-pipe vs one-pipe steam
