Welcome to the inner workings of the RPA

As I begin my new life as technical director of the Radiant Professionals Alliance, hereafter referred to as the RPA, I find myself surrounded by some very professional people who all have one goal in mind. That goal, if you will, is to “Grow Radiant.” That has always been the goal of the RPA since its inception back in 1994. And although the original concepts of delivering radiant comfort were essentially hydronic based, today it includes electric panel radiation, hydronic powered radiation, and even direct and indirect gas fired radiation.

Most of these buildings contained the typical cast iron natural gas fired boilers. They were operated at one set temperature, typically 180°F. In most cases, the boilers also provided Domestic Hot Water (DHW) thru either a side arm heat exchanger or an immersed coil inside of the boiler.

The leak detection job from hell
The very first question that was asked of me was whether or not I had the ability to find a leak. I answered positively, telling them that if there was a leak to be found, that I could find it.
The Jetson House goes green – Pt. 3
This is the final part of my series on the greening of the Jetson House, the iconic home that has been around since the early 1960s and has been seen by pretty much anyone who has driven the corridor of Interstate 70 between Denver and the western side of the Continental Divide.
The Jetsons go green
Over the years, I have chronicled all of the unique projects I have had the opportunity to work on. From smallest to largest, I have seen and done them all. I’ve never actually had the opportunity to work on any properties that were on the designated list of Historic Places. Until recently that is.
