    The gas heater in our autoquest 155. is under the bed, and when it starts up at night the reverberation is keeping my better half awake. (a) is the reverberation normally quite loud?, and (b) would noise insulation reduce the reverberation, or is there a better way to nullify the sound.

    Any ideas on how to reduce the noise, (not from the boss, that doesn't work), or other guidance would be appreciated.

    My suggestions...

    Mount the heater on softish rubber feet and don't screw down too tightly....Just enough to stop the feet moving
    Ensure all distribution pipework is secured and can't rattle around.
    Ensure nothing is resting on or against the heater body or pipework.

    If it continues it may be the blower fan is out of balance.
    Can be balanced but means a strip down to get to and remove the fan.

    If the reverberation is caused by combustion noise (roaring) there's little can be done.

    If its your space heating you refer to, get a silk filled quilt, no heating required and it will only take up the space for two bath towels. As for soundproofing, you need to isolate the heater from the van. I would mount it on a piece of wood and sit the lot on soundproofing material, like rubber or some of the stuff you get in packaging.

    We had a similar issue with a water pump.
    Ended up mounting it on an 1" thick pad of Styrofoam

    I think your motorhome uses the Whale blown air heating system, previously known as Propex and yes they can be noisy. Not a lot that can be done really its just a noisy heater although according to Elddis website yours should have the 4KW unit with "quiet night time mode" whatever that is.
