Natural gas heating

[DanielVetpath]

Hi folks:

I just bought an old commercial building to use as shop space. Essentially two garage bays, concrete floor, cinder block walls, side by side. One has a ceiling mounted vented natural gas heater. The other space has a wall mount ventless natural gas heater. Will the vented heater reduce the amount of moisture that accumulates from the ventless heater? Any experience or comments would be appreciated. Thanks!

Is the vented heater large enough to do both sides? I had a ventless heater once and hated it.

I think it may be, especially in the rear of the building where I will be working. The ventless heaters would be supplmentary in the front of the building.

the vented heater will vent only it's own combustion gas and water vapor

I wouldn't use the ventless heater at all, or replace it with a vented. They are just ok when they work right. When they get a bit older and start to get a bit flakey then you don't have any idea how crappy the exhaust can be. Where I live the city will not allow them to be installed.

Thanks for the input folks. Pretty much confirmed what I was thinking. Really helps me plan moving forward

There is one big benefit that a ventless heater has that people overlook - it doesn't require electricity to work. Not saying it doesn't have some major issues - I'm aware of them since I have one in my detached garage - but it works without electricity. I'm looking to add another option for heat in my garage now - but the ventless will stay. For the same reason that I haven't taken out the Black Bart insert in my fireplace in the house - it may not be the best and most efficient heat source available but it works when the power lines are down.

Anyone using a vent-less gas fueled heater should also have a carbon monoxide detector located in the space they plan to be for any length of time. Carbon monoxide is odorless, dangerous and can accumulate quickly. Your blood associates much, much easier with carbon monoxide than with oxygen. Once it gets into your body it takes a long time to get it out.
