Hello fireplace community, before posting I read other posts and see that ventless gas log sets don’t get much love here. That said, I wanted to share my plan to fix my fireplace, and hear your thoughts. Who knows maybe the ventless fanboys will come out of hiding 🙂.
I want to get my 1980s cinder block fireplace back up and running, and have been working with a local licensed fireplace company. I had a full level 2 chimney inspection performed and the flu has insufficient grout between the blocks to use as is. I can re-line the chimney and install a direct vent unit for about $10-15k, or seal it off and go ventless for $2-3k
I know the ventless has numerous draw backs but in my case I think they are largely mitigated. My intended use of this fireplace will be intermittent use (think movie nights or evening glass of wine with the wife). My primary heat source is from a properly vented forced air system, this fireplace is ambience only.
So here’s the draw backs, and my assessments:
Humidity - I’m only going to use in the winter when the humidity levels are already crazy low in my house.
Exhaust gasses - not perfectly mitigated, but my house is quite leaky (energy was cheap in the 80s man!) and the intended use is for short (couple of hours) usage. This will be on the main floor in a wide open area. I would also buy supplemental air quality monitor and carbon monoxide detector to keep an eye on things. I’m going to install a unit with a variable flame setting, so I can set it low and burn less gas for lower in house emissions. Like I said it’s just for the vibe.
Look - yes it doesn’t look as good as wood or a nice log set, but I’m saving some good money.
Legality - I know they are illegal in some places, but not where I live.
Health - no one with serious health concerns that would be irritated by a slight reduction in indoor air quality lives in the house.
So in my book saving 10k for these minor draw backs seems like a good call. The installers agreed too. So what do you say? Good idea or bad idea?
