Oasis

We have gotten comments about how load the burner is from neighbors and it keeps them awake. We can here it inside as well. You would think it would be quieter in such a nice coach. Has anyone else had complaints, if so has anything been done to quiet it a bit?

If you are hooked up to 50 amp power and outside temperature is warmer than about 35 degrees, you probably can get by with just using the electrical (AC1 and AC2) and not using burner overnight. Then turn burner on in the morning if necessary.

Have you heard a propane furnace run ? They are not quiet either.

Love that sound...

I was surprised when we tested the Oasis when buying the coach how loud it was. And when the furnace fans are all running inside, and the burner kicks on, yes, itís louder than I would like. But we are obligated to be in a very cold place for another couple of weeks, (30 high and 16 low!) and I LOVE how nice and warm it keeps everything inside and in the basement. And I still get my long hot showers! Walking through the campgrounds, I hear other rigs just as loud. So mine doesnít seem near so loud anymore! 😏 Of course, I have no way of knowing if yours is louder than normal. (I got a complaint once in a previous rig about propane water heater noise... thereís always someone)

You can buy a Genturi-type muffler for it if you want to try that. Or call the Genturi people and ask how much it helps. In our New Aire, we absolutely need the burner to take a shower with the outside temp below about 5 degrees. With the heated floors, we don't need the burner or heat pumps to heat the coach overnight.

Happy trails

They make a muffler for it. Has anyone installed one and does it make a difference? When I raised my Oasis exhaust I called them about adding one and was told Newmar didn't design it for one.

Oops, I meant to say 55 degrees.

A few things.....first, it's a burner, no different than a propane furnace on other RV's, which are just as loud when they run.

Second, my 2014 DS came with a muffler on it, but my 2019 doesn't have one. I don't know what year they quit using the muffler. I called ITR (Oasis) and they said the muffler is still available. I think it's about $150.00. They said that it was Newmar that decided to not to use them. If you have one, it looks like the photo below (my 2014 DS). It would be nice to have a decibel comparison, but I don't recall my 2014 being any quieter than my 2019.

I know some people aren't aware that you can run both elements and the burner at the same time. If you have the electric elements on, you'll substantially cut down on how often the burner comes on. The only time you should be running the burner only, is when there is no shore power.

The OP doesn't say if he's connected to shore power, but if so, why not run the heat pumps if you're concerned about bugging the neighbors. On my 2019, if I have shore power, I can heat my coach five ways, (1) heat pumps, (2) heated floors, (3) fireplace, (4) furnace with just electric elements on, and (5) furnace with the burner on. If you use the furnace with just the electric elements in very cold weather, the system will get hot, but the interior fans will run much longer possibly all night.

I had a muffler on mine and knocked it off pulling out from under my carport, then I ran over it. Ordered a new one installed it, did the same thing a month later! 150.00 gone. Decided to do away with the muffler. Didn't make any difference on how loud it is with or without one. If you look at one it's really more of a resonator because the exhaust runs straight thru it there is noth9to dampen the sound.

The ITR muffler makes a noticeable difference. I wanted the muffler mounted as high as possible so I installed a custom length black iron pipe out of the burner box. Now the muffler has about a 1/4” clearance from surrounding metal and doesn’t get unreasonably warm (believe me, I’ve checked!). ITR also has a “muffler” available for the intake air hose that reduces low frequencies even more.

I also tucked my exhaust pipe tighter to the body by using a shorter black pipe, as I was dragging on the steep incline in my backyard. When I checked my 2019 DS, they installed the downpipe really close to a structural rail under the coach. I don't think a muffler can be installed, without it hanging down quite a bit.

Conclusion

OK after reading all these post my conclusion is some of you were wrong and some of you are correct. After talking to Oasis they said that a muffler will definitely make a difference. I could not justify $150 for a glass pack muffler. I purchased a automotive glass pack for less than a 1/3 and it made a huge difference. Now itís about the same if not quieter than a typical propane hot water heater

Long before I had an Oasis system, I always thought it would it would be nice to have quite running propane furnace (mentioned above) and water heater. Also, there are also some noisy ac units. Both furnaces and ac units are also noisy on the inside. I've resigned myself to the fact that the RV lifestyle is sometimes noisy and that's the price we pay for these conveniences. I still think there is a way to quite the inside noise from these units. To be fair, if one is quieted, all should be quieted.

I cut a section out of the pipe under the coach(just like in Ducthstardan's picture). The muffler I got was a Trush Glass pack.
