Looking at diesel heaters for keeping my garage warm this winter — any suggestions?

[Emily Parker]

I've been reorganizing my garage in Wichita into a small workspace where I can tinker with projects, and it gets uncomfortably cold out there from December through February. It's a detached single-car garage, not huge, but drafty enough that a space heater barely makes a dent. I've been reading about diesel parking heaters online and I'm trying to figure out whether one makes sense for a space like mine. What I'm most unsure about is the exhaust and venting side of things — my garage has no real place to route it out cleanly except a small wall vent. I'm also concerned about noise since the neighbors are close, and about whether the fuel smell becomes noticeable in an enclosed space. I don't want to spend money on something that turns out to be overkill or a hassle to maintain. If anyone here has run one in a similar setup, I'd really appreciate hearing what worked and what you'd avoid.

 

I came across this Best Diesel Heater of 2026 https://ratethepick.com/category/diesel-heater while looking into the venting question, but it still doesn't settle whether a small wall vent in my drafty single-car garage would work. I'm leaning toward holding off until I understand the exhaust setup better, since noise and smell are still worries.
