The Last Working Jobsite for Minnich Mechanical Design

Share With:

After 38 years in the hydronics business, Stephen Minnich of Minnich Mechanical Design is hanging up the tools. The Hub’s John Mesenbrink caught up to Stephen on his last jobsite, a 24-zone radiant system at an apartment complex in Wheaton, Ill. The change-out consisted of removing two 400,000 BTU cast-iron boilers with no boiler protection and no mixing among other hydronic issues that cut down the life of the boilers by 10+ years.

Minnich is installing for two Lochinvar KBN models, an upgrade from their KHN models to remedy the problem. Check out the video here.


As far as what Minnich will do in the next chapter of his career, Minnich has accepted a position with an engineering firm downtown Chicago as an HVAC consultant for multi-residential units on the Chicago area. Congrats on a great career and good luck with the next chapter in your life!
