Hello all!
We are rebuilding one of our cars to put into service, and I wanted to ask for your experience with baseboard electric heat. I have worked on and ridden many cars with electric baseboard heat replacing the old steam heat. Some had a continuous line of heaters run under the windows from end to end, some were spaced seemingly willy-nilly.

Here's my question- spacing and size. This car will have overhead heat as well, but the baseboard is great to quickly knock the chill off I've found and as a backup if the overhead is out for some reason. It is a former ACL coach that had been converted into a bar lounge, that we are going to set up as a bar table car, with the ability to remove the tables and chairs and put lounge chairs back, or an open space for whatever (my wife is in several quilt guilds that are chopping at the bit to do a 'quilt retreat' on a railcar)

So what have you found works best? I was thinking 3-4ft 750-1000 watt spaced under the windows. Two in the hallways, and maybe one each 4ft in the large restrooms. Since the A/C system I'm using is 208v 3 phase, I'd like to keep that for the floor heat too so all HVAC is the same panel. I know 208v 3 phase baseboard heaters are relatively cheap, like $120 for an industrial grade 4ft 1000 watt.

Thoughts? I would like to hear everyone's thoughts on spacing them.

Thanks!
