Important conversations that never happen, but should — Pt. 1 
You have two ears and only one mouth. Listen to the consumer to find out what their wishes, wants, needs and expectations are before you speak.
Reduce your energy consumption for heating domestic hot water by 50 percent 
There are actually a lot of ways to reduce energy consumption related to the production of domestic hot water.
Radiant solutions and the beginning of a new age…
Imagine what the thermal efficiency of a flat plate collector would be if it was looking at a huge block of ice as its target for its produced energy?
Notable achievements and changes too 
As I enter into the fifth year of my career with the Radiant Professionals Alliance (RPA)... I feel a great deal of pride in knowing that we, as an industry have become stronger today than we were when I first joined the RPA.
Inadvertent code violation  2
For many years, there has been a practice in the field of hydronics of taking a code-compliant, dual-use, tank-style water heater and using it for both domestic hot water (DHW) and space heating...
Looking back on the year 
As we close in on the end of the year, I’d like to look back at what has happened during the last year, and thank those responsible for their assistance.
System fluid volume revisited 
As winter approaches, the task of estimating the volume of fluid in a given hydronic system rears its head once again.
K.I.S.S. — Keep it sweetly simple 
Many people have their own interpretation of this acronym. Some say Keep It Simple Stupid. I prefer one I developed, which is Keep It Sweetly Simple. A perfect fit for hydronics.
What is the ‘point of no pressure change,’ and why should you care? 
During a recent code hearing, it was pointed out to me that the pressure at the PONPC will in fact change due to expansion and contraction of the working fluid, so the name is somewhat misleading.
Difference between circulators, pumps
Many industries suffer some of the same problems that our industry does when it comes to the jargon used by its tradesmen.
So you think you know radiant eh…. 
I talk to people on a daily basis about radiant heating and radiant cooling systems.
Non solid state control strategies, Pt. 2 
In last month’s article, we began to rediscover non-electric thermostatic radiator valves (TRV).
Non solid state control strategies 
Here we are today, with more computing power onboard even the lowliest of boilers than there was on the spacecrafts that circled the moon.
Hydronic certification becomes reality 
Many years ago, the Radiant Panel Association, predecessor of the Radiant Professionals Alliance, developed the first certification program for radiant installers and designers.
