Any expiriance or analyse between radiant wall vs floor heating.
A found on net a lot of analyse of floor heating but nothing about wall heating.
A can't istall floor heating system and consider installation of radiant wall heating.
Also any expiriance between radiant wall heating install on outdoor vs indoor wall

Please send me some link

I talk about radiant hydronic PEX tube heating.
and
Instal on outside vs inside walls of house

I generally recommend ceiling instead of wall if possible.. less puncture risk.

If wall is in use, stopping it at about 5' in height and using a chair rail or other physical indication of where the radiant stops is a good idea.

It works though, definitely. a panel radiator is about as good though.

NRT Rob,

I have a radient issue concerning walls and floors as well. My issue is how to keep the radient heat in the floors and not moving to the walls. I will have ICF walls and a composite slab on steel truss floor system. I should also note that the ICF wall will have 4 5/8" of foam on the outside and 2 5/8" on the in side. With the majority of the foam on the outside, the 8" concrete core might be considered as insude the heated envelope. So on the mid level slab, a thermal connection is not so bad. My issue comes in where I have an outdoor patio, also slab on steel at the same mid level floor height. In the case of the patio, I will use a themal barrior/expasion joint. The issue gets more complex where the flat roof, slab on steel, connects to the ICF walls. The concrete roof will be insulated from the underside of the slab and will be used as a roof top patio. This makes the roof slab outside the heated envelope. I would like to isolate the roof slab from the walls. Have you encountered any questions like this?

I have not encountered that construction detail, personally. Is it possible to do a vertical piece of rigid foam between the ceiling edge and the wall? Then you have the top of the wall to consider still...

The ceiling mounted radiant heating panels did the job for me.

Several companies make electric radiant heating panels that use long wave infrared heat to keep people warm.

The panels can fit on the ceiling or near the wall/ceiling joint or Cove.

The new technology makes the energy use very efficient.  Allows zone heating. Low wattage and fast acting makes people feel comfortable at lower air temp.

Hi,
We just completed our 2nd heating system with various radiant heat systems in floors, walls, ceilings and stand alone radiators: http://web.mac.com/mldelany/iWeb/Site/Schoolhouse%20finish.html

A lot depends on configuration of structure and intended use. In an adaptive reuse of an historic schoolhouse for office space, a radiant wall worked well because the ceilings are 18' and the occupants are at desks along the walls that are heated.

In general, you should expect equal performance, certainly for total heat loads and losses. If proximity is improved by installing in walls, the overall comfort levels will likely also improve.

What are your specifics?

From an energy standpoint, I wouldn't put radiant in exterior surfaces - that increases heat loss.
