The main advantage of the 120 volt system is that if you protect the circuit
with a GFCI device, the protection will cost a small fraction of the cost of
a 240 volt device. Most "line voltage" thermostats are 2 pole so that will
not be an issue.

Otherwise, just about everything says go for the 240 volt system. Smaller
wire, lower losses between the panel and the heater, less temptation to
"tap" the supply line.

Hi,

I'm a little confused about the whole 120V vs 240V things. More
specifically, I'm now deciding whether to put in 120V or 240V mats to
heat the tile in my bathroom. My electrician told me to "of course,
put in 240V" because you then need a smaller current for the same
amount of energy. Yeah - I understand that from my physics class - but
so what? Is it safer? Is it more efficient? Does it work faster?

Further, I called the floor heat company and they told me that 120V is
for up to 150 sq ft and 240V is for 150 sq ft to 300 sq ft. So I don't
know which one to go with anymore.

Please shed some light on this issue. Thank you!
