I'm not recommending you do it, but my reloading set-up was in my unfinished basement less than 8 feet from the gas hot water heater for over 20 years and the only problem I ever had was when the line coming out of the water heater sprung a leak once while we were on vacation and sprayed down my equipment for 3 days.

Now that my kids are out of the house, it's all been moved upstairs.
