Customers with steam heating systems often ask if there is any way for them to reduce operating costs. In addition, after asking, they note there is uneven heat distribution and want that resolved, too.

I first encountered formic acid erosion/corrosion when our installed air conditioning and heat pump evaporator (indoor) coils began suddenly leaking refrigerant in 2008. These were not old coils either, and some had only been installed for a year when the issues arose. 

My grandparents lived in Saint Clair, Pennsylvania, which is in the heart of the anthracite coal region. Pop-Pop had a Westinghouse Appliance store and serviced everything they sold. In addition, he had helped to wire homes when electricity first became available and serviced lots of coal boilers. 

When I first entered the trades in 1972, residential tank-style water heaters shipped with the aquastat set to approximately 140° F. Dishwashers had no need to incorporate a sanitizing cycle. Around 1977, water heater manufacturers were required to lower the aquastat temperature setting to approximately 120°, and now, dishwashers needed to incorporate a sanitizing cycle where rinse water in their reservoir was raised to 140° or higher.

When I first entered the trades, F. W. Behler installed lots of galvanized and copper spouting. I was not keen on working several stories above terra firma, which hampered my speed in getting-er-done. What to do to overcome my fear of heights? Go skydiving of course!

Thanks to folks like you, I’ve been able to delve into many forensic examinations of mechanical mayhem and then offer solutions based on solid engineering guidelines.

On Sept. 1, 1979, I struck out on my own to become an independent PHVAC mechanical contractor. 

In 1921, Chetwood Smith had this to say in the American Water Works Association Journal, “I have seen over 35 explosions from overheating water. 

In 2003, I had the opportunity to attend ISH in Frankfurt, Germany. 

Assembling prior columns, updating older information, along with some new content for the four eBooks has been an interesting review of my 48-years as a mechanical contractor.
