but it sure is easy to say you are!

we all know radiant can be quite efficient. But we also know that poorly executed jobs can be quite INefficient.

I think in the discussion of being "Green" one of the very important aspects is identifying the boundaries... when ISN'T radiant green?

Is high temp radiant green?
Is it green to oversize boilers?
Is it green to draw hundreds of watts of electricity when 90, 60, 45, or even 8 would do?

We could probably have threads on every topic with some real points on each side. But ultimately, let's make sure this forum doesn't turn into a back-patting "echo chamber" and instead have some hard discussions about the real benefits and limitations of radiant in the "green" marketplace... and make sure we don't engage in "greenwashing" just for the sake of sales.

Rob,

Radiant is all about comfort... so says everyone out there making inexpensive systems. BUt GREEN is not always easy to do. I love when I get a call from a HO saying that since they had their rfh installed their fuels bills went UP. Usually I find this due to two issues. One is that the HO keeps their thermostats up at 72F or because they were told they would save 14% of their fuel that they keep their tstats up at 80F... again, user issues of not being educated.

the other issue I find is the extensive use of three way valves without out door reset, especially in joist applications without insulation. I'd like to find the guys out there teaching this method and cut... well, you get the picture.

Scratch a poorly performing radiant system and you often find poorly executed or neglected insulation. Unfortunately because this is where the radiant contractor relies on another trade without their own oversight.
