Plus they just look nicer, and are easier to install….

I am designing the circuit(s) for my basement apartment (cca. 800 sq ft) baseboard heating solution. I am planning to buy Berko HBB Series heaters and distribute them as shown in the below table. All have a voltage of 240/208.

Code:
Location        Model       Length(in.) Watts       Amps
-----------------------------------------------------------     
Living Room     HBB1504     70          1500/1125   6.3/5.8             
Bath            HBB504      28          500/375     2.1/1.8             
Bedroom         HBB1254     58          1250/938    5.2/4.5             
Hallway         HBB754      34          750/563     3.1/2.7
My questions are:
1. Should I split them into two circuits (living room and bathroom in one, bedroom and hallway in the other) or is it OK to keep them all on one circuit?

2. Is the voltage a factor in determining the wire gauge? I know that the amperage is. E.g. if I split them in two circuits so that each circuit bears less than 10A each, can I go with AWG 14/3 even though the voltage is double than usual? Or simply put, which AWG should I use for either scenario from question 1.?
I have an extensive experience as a DIY electrician, I have pretty much rewired most of my house and have set up one 240/120 circuit for my dryer (used AWG 10/3). But this is considerably lower amperage so I am not sure what AWG to use.

first you must decide which voltage you are going to use ....

120 or 240

first # is the 120 amps .. second is the 240 amps ...ie Living Room HBB1504 70 1500/1125 6.3/5.8

240 takes 2 spaces in the panel for each circuit ...


next BIG mistake that is made with a lay out of electric base board heat is that you CANNOT put an outlet above it ....


so some manufactures have an optional outlet that fits into the baseboard ...

so check your lay out !!!!! you may need the neutral ...LOL

Look at the amperages, those are NOT 120 - 240v amperages, try 208 - 240v amperages….

The amperage would be cut in half it they were in fact 120 / 240v amperages….

IMO, its pretty dumb to wire an entire house with 120v baseboards, 208-240v units will save you material costs….

me personally ... knows that code is 10 watts BUT .. you get no extra cause you have a basement .. that is gaining heat from up stairs and being underground .... you will have way more heat than you need ....in most case but that is "building" code not electrical ...


maybe 1 stat for living/hall on wall

the rest the cheap dial on the baseboard would be fine ...

I actually want two thermostats: one for the living room and bathroom, the other for the hallway and bedroom.

Does that system work out well in the rest of the house?

Let's say it would...
buy a second thermostat and the second relay too. NBD.

And all controlled by ONE thermostat... right?
What would happen if you split that up?

the difference is that the radiator system has a single heating source while baseboard heaters have one each so it is easy to have differently heated rooms.

Nope. The source or nature of the heat doesn't matter.
Either the space (and the space next to it) is all heated or it isn't.

i suppose a better analogy is central AC vs. window units. With the former, you control centrally and with the latter you can control each unit individually and one room can be cool while another one is not.
