Absolutely. The cost for venting the 80,000 btu was nearly the cost of the heater itself. I do have to say, very early on of course, but I couldn't be more pleased with it in the first 12 hours. I finished the vent and my gas connection yesterday afternoon and then did my electrical and thermostat wiring after supper. I had already run a dedicated 20 amp circuit 40+ feet across the shop from my panel as I had read from forums over time that was probably the best idea, and then when I get the cover off the JB on the back of the heater there were 3 stranded wires that looked like something on the back of a car stereo was all, could have just plugged the thing into a wall outlet. At any rate, the hard part was done, so wired it up, turned on the gas and leak checked all the fittings, and bumped the t stat up 5 degrees over ambient. Within 15 seconds it was running and within 60 it was putting out strong heat. Have always heard "you'll hate the noise"... thing is quieter than a household tower fan on high, could literally have a phone conversation with someone while standing directly under it and they'd never hear it. It showed 45 in there this morning when I woke up, I bumped it to 55 on my phone and by the time I had showered and sat down to breakfast, it had already cycled off and was at 55. Cheapy amazon wifi thermostat for the win on this one too, I think I gave $60 for it or something like that.
