Radiant Floor Heating/Yaga Trench / Canal Radiators


Do you have a view on trench/canal radiators (e.g.,  They are more common in commercial buildings, but would be subtle and space-saving in our small 1900s home.  

Hello Susan,

Yes I am quite familiar with Jaga and the trench radiator. It is in fact a fan-coil or fan-assisted fin-tube and not a "radiator" per se.

As the webpage you site displays, there are few ways to combat the inevitable cold spot created by floor-to-ceiling windows or sliders as the case may be. This is certainly one way to address the issue enhanced by the fan-assist feature.

Though Jaga makes some of the most interested and artful radiators anywhere this particular model is the least interesting to me and certainly not new in any way, save the low-temperature feature.

The greatest downside is the regular maintenance, read-cleaning-that must be done regularly to assure continuous and consistent output. I would only have one if the central vac were tied into it so I could sweep the kitchen into the "trench"...or I was cold and couldn't get enough radiant heat from the adjacent floor, wall, ceiling or nearby radiant panel.
