Thanks for starting this thread!  There is a good write up on a radiant wall here:

Interesting…

In colder climates, before installing flooring in a basement people will often use sheets of insulation on the floors as well as the walls. The frost line goes very deep where I live, so a basement floor will get very cold. The insulation acts as a thermal break. After installing staggered sheets of tongue and groove insulation and taping the seams, a wood, carpet, vinyl or even ceramic flooring can be installed. How great would it be to have a warm basement floor in the winter?

Another Interesting & Somewhat Different Radiant Wall example HERE...
in the east of France (which gets VERY cold !)
http://www.batiactu.com/edito/le-chauffage-par-les-murs-pour-une-renovation-en-m-35059.php

The article is in French, but here is a resumé of the main points:

  • radiant-wall system is uncommon in France, but very common in Germany
  • this is whole-house project (older property, 2600 square feet)
  • uninsulated, outer walls of 2-ft-thick masonry
  • project includes new 24 kW water boiler from 4 solar panels, with 1000-liter storage
  • and standby installation for future wood-burning stove
  • COPPER tubes are laid in channels cut into lower parts of peripheral walls (only)
  • cost of installation: 35.000 € overall, of which 29.000 € for boiler
  • 1 Euro = 1.3 USD approx, therefore = 45,000 USD and 38,000 USD respectively
  • owner  hopes to save 10 percent on heating bills
  • he places great emphasis on the anti-microbian qualities of copper, but one of the commenters says that RINSING of the new system is essential, as well as pH control of the water used in the system.

Owner helped with self-installation of (sheathed) copper pipes, "to cut costs"...

(wonder what this does to the 10-year guarantee ?)

Enjoy the radiant heat !

It seems like there was someone on the old Simply Solar forum that was going to try a radiant wall. It may have been 2 years ago. I wonder if the guy ever built it.

[smile] Greg a warm floor in general regardless of location is good.

That's why I installed pex under my floor. Of course, now, I'm waiting for the sun to appear, which isn't likely for several days.

The incoming snow 'does' give me the opportunity to fire-up my wood-burner-boiler project to see how well it performs. [smile]

Was thinking about what I could do in my old farmhouse and some sort of radiant wall system popped in my head.  Good to see I wasn't the first to think of it. [smile]
