Question 110 vs 220 baseboard heat

I have heard that 220 is more efficient than 110. I was just wondering just how much of a difference there is. I need to install an 8' in the bed room, a 4' in the bath, and a small one in the mud room. Can I put them all on the same circut also?

If you've got 2- 5000 watt electric heaters. One is 115V and the other is 220V the 220 will use less amps resulting in a little lower cost "not much", but it will give you the potential ability to use less breakers. So depending on the total amp draw of the 3 heaters you may be able to use 1 breaker.

Amps are amps so its the same . Thats like 110V you have one leg. Say 8 amps on 110V you have. On a 220V you only draw 4 amps on each legs. But thats still 8 amps at the meter both legs count. A KwHr is 3415 Btu of heat

ed is exactly right. 8 amps on 110 volts is equal to 4 on 220, but 220 has 2 110's, so we are back at 8.

There can be cost saving assoicated with 220 v, based on smaller breakers, wire, etc

But the job has to be pretty big in order to realize those savings.

But to say 220v electric heat is more EFFICIENT then 110v is simply not true.

240 volt, or ven better , 3-phase , MOTORS do operate more efficiently than a 110 volt unit.

But in terms of baseboard resistance heaters, that is not true. However, the savings in terms of smaller wire size make 220 more attractive for that type of heat.
