ramblinboy Report post Posted December 22, 2010 Recommendations on heating the interior without running the furnace - anyone? http://www.mrheater.com/ProductFamily.aspx?catid=41 This heater can only be used in a recreational or commercial enclosure with a window or roof vent. It may also be used outdoors. Share this post Link to post Share on other sites
wolfe10 Report post Posted December 22, 2010 I opened the Owners Manual on the MH9BX and see these warning in bold print: WARNING: WARNING: If the recreational or commercial enclosure does not have a window or roof vent, DO NOT USE THIS HEATER INSIDE. And: Proper ventilation air must be provided to support the combustion air requirements of the heater being used. Brett Share this post Link to post Share on other sites
Guest BillAdams Report post Posted December 22, 2010 Are you hooked up to shore power or not? If you are then I recommend a good ceramic electric (or 2) heater. If you are not then I suggest that you use the coach heating system. If you want to move outside these options to a propane powered interior heating source you have to be acutely aware that you must find one approved for interior RV usage and you must have enough outside air being returned to the RV to prevent asphyxiation.

ramblinboy Report post Posted December 22, 2010 Thanks Bill. No shore power. I want to run off the propane main tank. Need to connect a line from there along and under the coach then up inside with a quick connect. There are ceramic propane heaters that need a window cracked for combustion air. Anybody have one? Thx Wayne Are you hooked p to shore power or not?If you are then I recommend a good ceramic electric (or 2) heater. If you are not then I suggest that you use the coach heating system.

jcnit2winit@aol.com Report post Posted December 22, 2010 Ceramic heaters are much safer in an RV. Being an RV tech I have seen the damage caused by these type of heaters and sometimes there is not much left to the RV! I highly recommend ceramic. Share this post Link to post Share on other sites

ramblinboy Report post Posted December 24, 2010 Thanks Paul. Sounds like it does the job! I believe the ceramic heaters don't put out as much CO2. Good advice not to use when sleeping!

ramblinboy Report post Posted February 9, 2011 If you do a fair bit of dry camping or boondocking here is a product line for auxiliary heat without firing up your genset: http://www.empirecomfort.com/ It can be plumbed into your existing propane tank with low pressure fittings available from your supplier. Be sure to get the model with a thermostat to adjust the output automatically. These are ventless and use room air for combustion but you should crack a window near the unit to draw outside air to compensate. Propane is cheaper than gasoline and there's no disturbing the neighbors when you need heat. Hardware should run under $300USD for a 10K BTU for a space of 300 sq ft. Your camping lifestyle would determine if you'd need one of these units. Share this post Link to post Share on other sites
shields Report post Posted February 9, 2011 In addition to keeping a window open, you might also place a CO2 alarm at floor level near the heater. Tim Share this post Link to post Share on other sites
