A warm concrete floor in a house probably had hot water pipes in the
concrete. Possibly electric coils though. Anyway this would not be much
different from any other way of heating a house. The electric coils under a
drive way to keep away the snow and ice is another story. We are talking
I've been doing a lot of research into heated floors. There are two main
kinds of radiant floors, electric or hydronic (water). You can bury pipes
in the cement floor, or place them in the joist bays beneath a wood floor,
then use hot water flowing through the pipes to heat the floor.

It takes a load of heat to melt any significant amount of snow and ice. Over
night you might release enough surface to make scraping ice off of the
cement easier but unless you get pretty warm weather you won't be able to
afford to plug the electric in.

Did you find it strange that job site accidents with table saws aren't included

Yes, not only was I surprised that job site injuries weren't reported as
part of this report, but since experienced users are at greater risk of
injury, I can only imagine the numbers are pretty scarry for job site
injuries.
It is so interesting to read the comments from all the wood
I live in a small town with a population of just over 5,000. I attend at least
two hand injuries per year from saw cuts. There are several more less
significant injuries which never make it to my Department. Not all are table

OK Mike,
Then it sounds like the electric mats aren't as bad as I thought. Are you
just using them as a comfort heat source and not a primary heat source?
Are they thermostatically controlled or do you turn them on and off when
you want the heat?

The heat is thermatically controlled. So, my wife sets the temp, and we go
with it.
The first instillation at our old house was a primary heat source. We have
45 sq/ft of heating mat installed, and it heated a 135 sq/ft room fine.
this was a bathroom in a basement, and the mats were installed
under tile. Well, starting from the bottom, I have the plywood subfloor,
the heating mats, Kerdi membrane, and tile.
I think the mats I got, if you put it under wood, you need to put a layer of
thinset over the mats first, then glue the wood down, or use a floating
floor.

I don't believe that for a moment.
If it is below freezing it is going to take a lot of heat just to raise the
temperature of the surface above freezing. A cement walkway has a lot of mass
to bring up to temperature. Then there is the latent heat. it takes something
like 40 calories of energy
