Think about it 75% of the noise is the fire box noise. I installed the Cheap Heat system on my gas heater and have no problem with noise operation of the heater. The blower sound is not that load and the heat this system puts out is very evenly distributed and it also keeps the belly warm. I been having this system in my camper for over five years now. My son is living in my camper and is using the heater and has no problem with the heater system. I have saved on propane use and would not own another camper without this system in it. I did install theheap Heat system myself and any one with DIY ability could perform the install. I love my Cheap Heat system!
