Quieter alternatives for propane furnace in extreme cold

After considering all of my options between trailer, sprinter van, etc., I determined that a TC works best for my purpose which is travelling to, and boondocking in, remote areas. Several areas that I am considering travelling to in the winter are in northern Canada where the temperature may reach 0 Fahrenheit. I must have working water system in these trips, which is doable with a propane furnace after some additions and modifications. I am open to buy any lightweight short bed camper such as Northern Lite 8-11SP, or Wolf Creek 850, or Lance 865.
The problem is that DW sleeps very lightly at nights and the propane furnace noise will be a deal breaker (or even non-starter) for her. I am looking for alternatives to propane furnace. I am open to replace the propane furnace with more than one appliance if needed, but the one or more appliance must heat the basement, camper, and water. What are my alternatives.
So far Alde system sounds like a good option. But I am unsure about how much and what kind of challenge should I expect if I want to replace a propane furnace with an Alde system.
Another good option is a Truma Combi. Again I am unsure about the challenges and complications I must expect. Although the first challenge is to find a Truma Combi.
Another option is to replace the propane furnace with an Aitronic D2 which will heat the camper and basement, and buy a separate water heater. Airtronic D2 is a fantastic heater, but this route requires buying two appliances and I am yet to find an efficient, lightweight, stand-alone water heater.
Yet another option is to heat the camper using Mr. Buddy, Plat Cat, or panel heaters and then use a few fans to push warm air into the basement. The problem here is I still need to find an efficient, lightweight, stand-alone water heater. Moreover, I am not sure whether pushing warm air with fans into the basement will keep water tanks from freezing in extreme cold that we will be in (I have considered adding thermostat-equipped light bulbs or small electric heaters or pads close to, or around, tanks, but found that unrealistic and prone to failure given the complexity of adding several of these and their electricity consumption).

If you have any idea about any of these or something different that may direct me to a solution I have not thought about, please share it with me. Thanks!
  • The little cheapo china diesel heaters will be quieter and use less electricity. There is an issue with a clicking noise with the fuel pump unless you can mount the pump somewhere where it cannot be heard. Click is similar to the piezo ignition click of a furnace.
    The down side is these heaters will need cleaning from time to time.

    The best solution is a small inverter generator, a quiet one, located a few feet away and run an electric heater or two, the 2nd being for basement, and maybe an electric bed warmer.

    Otherwise the propane furnace that does have a loud fan is a really good heater. It does use a lot of electricity for the fan, and at zero deg it would run all the time almost, so with long winter nights you would need some amp hours for sure.

    The Buddy heaters do just put a lot of moisture into the air and at zero cracking windows is not as ideal as it is at 50.

    Eventually anyone will get used to normal sounds. I never did with the heater as I did not run it enough to get used to it, but every night all the time.... well thats your call alone.

    I would explore the ear plugs route and try it at home before looking at expensive solutions each with their own downsides...
  • You will encounter temperature far below zero Fahrenheit. Right now, large portions of Canadian Prairies are below minus 40. Unless you have electric plugin power, you will not have enough propane or battery capacity. Solar power will also be almost zero with low sun angles, short days and snow cover. Even if you are able to keep the interior heated, your water system will freeze solid. Also, you will not find many places to refill your water tank or to dump the sewage. I live on the Prairies, it is extremely harsh during winter.
  • The water heater is easy. Just turn it off when sleeping and the burner will not be heard. If heating water via electricity, in time the element will make noise as it begins to corrode. Again, the solution is to turn it off at bedtime.

    Boondocking in remote areas essentialy means no electric without a generator. If willing to suffer a remote generator or have electric, there are electric options for a furnace. In the small confines of a TC, a 1500w portable electric oil radiator heaters and fans can be quiet and very effective. Otherwise, anything with a burner or a fan will be heard at startup. I even wake up when I hear the little burner on the fridge start. I feel her pain.

    Learning to sleep with low level music on all night has helped the burner, fan, and other appliance noises to be less noticeable.
  • Also consider a heated mattress pad to allow the furnace or other system to run at a bare minimum. Unless vented the catalytic heaters produce unwanted moisture too. Assuming you have power to plug in you can add heat pads to the water system to prevent freezing. www.ultraheat.com I added a water circulating pump to prevent freeze up.
  • You're going to experience temps WAY below 0 F where you want to go. And a whole lot of other issues will come up other than water. Even starting a generator could be an issue.

    Where do you live now and what's your experience with winter camping of any type?
  • Don't Cirrus campers come with an Alde heater from the factory?
  • Ear plugs...

    You seemingly have the desire and tenacity for your project, but my quick response is 'wince'. But curious.

    To answer the question about forcing the heat into the basement, our AF (and others no doubt) use nothing more than a small fan that circulates a fraction of the room air. The propane heater is extremely quiet and we leave it on all year. The heat from it helps also. Long term zero temps are clearly a different story, but we've had no problem being in the teens for a few days, or below freezing avg temps for week plus.
  • First, I’m a light sleeper. My wife never wakes up.

    I find the propane furnace fine, but I do a few things. 1)Turn down the thermostat at night. We usually have it at 60. 2)Put Reflectix in all of the compartments, under the bed, and in all windows and skylights. We remove the Reflectix from windows/skylights during the day. 3)Have a warm cover. We use down.

    Those things help us minimize the number of times the furnace cycles.

    Finally, there are some older threads on winter camping. You can do a custom search or google search to look through those archived threads.
