in THE MAIN WALL
I am doing work in a laundromat, in back of the machines is a small hallway roughly 2 feet wide by 60 feet long, the wall and that area gets cold, like freezing cold. I am putting new washing machines and redoing all the water line.
The question is should I put a small furnace and run duct work, or have some type of vent-less heater that runs the length of the wall. I only need it to go above freezing so i am thinking something 55 degree. Gas is available with ease.

    If that's an outside wall, use some sort of direct-vented heater. I would NEVER install a "vent-free" unit of any kind.

    Particularly in a space such as you are describing. But there are lots of nifty little direct vent gas heaters which will do the job.

    Rinnai direct vent wall furnace is my go to for places like that. Nice units, quiet and reliable for not too much coin. If not oversized, will modulate and run very efficiently.

    Is there no other heat in the mat? For me, the dryer service hallways were a losing battle due to all the fresh air required. I thought about dumping a little heat from the furnace in there but I ended up keeping the dryer service areas insulated from the rest of the space.

    Rinnai is a nice unit but if the dryer's are in the same area it has the chance for lint problems... I'd suggest using an empire...not as efficient but not effected by lint and it runs if the power goes out...

    I agree, lint will mess with anything with a fan a radiant type heater or a gravity heater like the Empire I would vote for as well.

    Something with no fan. I didn't put it together that there would be lint in that area. I was just thinking of the washing machine service area.

    Is it all the makeup are for the dryers that is making the space cold? If so, can you preheat incoming outside air and then duct it to that space?
