No doubt, I just read back in the thread closer. Yeah those are nice for sure. I think thoses are like the one my uncle has. He has a smaller garage, it take a while to heat up, but like you said once it gets there it is silent practicly and stays constant. The big ass salamandor like the one we got is a fucking jet. but it has a thermostat on it so it shuts off… but without good insulation it would run on and off every 15 mins or so i bet.
