My contractor mentioned to me (but couldn't remember the brand) that
there exist hot water radiators that go between the joists on the floor
below and release heat through an opening in the floor. Could someone
point to a link to a radiator like that?
It will be fine, its also comonly embeded in concrete and your floor
isnt anything abnormally thick, it will heat more evenly, under you so
your feet are warm and since its under you heat is distributed more
evenly. If you are considering a new high efficency boiler Ever,
condensing boilers start loosing efficency as they heat water above
140, my radiators need 160-170 and radiant tube around 110f, the new
highest efficency instals are radiant tube, under tile and everything.
Interesting you should mention that underfloor crawl space
Our almost completely in ground, full height, uninsulated concrete and
concrete floored basement rarely goes below an absolute minimum 45
degrees F, in even the coldest weather wth upstairs heating turned
down low. Probably around 58 degrees upstairs at floor level.
When the upstairs is heated to to around 68F considering that some
heat leaks down , the unheated basement area is typically at around 50
- 55 degrees. The wood stove or plug in electric heater quickly brings
the temperature to a suitable point for normal physical activity in
less than an hour. The internal dimension of the basement are approx,
Height 8 feet, Length 46 feet, Width 32 feet.
