I'm in the process of figuring out how to heat our 875sf fixer-upper cabin in the southern California mountains (winters not too bad - lows usu in the low 30s/highs in the low50s). It's an open floor plan with the bedroom about 25 feet from where the stove will go, so we want quiet operation, and ideally thermostat controlled. Although we're on propane only, we have decided it will be worth the extra cost to operate a propane fire to have the instant gratification of flicking a switch for ambiance, along with less mess/maintenance compared with pellets or wood. However, now I've completely fallen for the Malm Spin-a-Fire or Carousel fireplaces, and I'm not even sure if these are legitimate, house-warming, efficient solutions. There is little information in the way of reviews or efficiency ratings, so I'm hoping someone on this forum may have opinions and thoughts. I'd like to call Malm directly and ask some questions to help this assessment, but at this point I'm not even sure what to ask, or what information I'm missing. Here are the features listed on the webpage: BTU Input Natural Gas 63,000 / Propane 55,000 Wall Clearance 6" Requires Class A All-Fuel Chimney Adjustable Flame Height Remote Control Included Thermostat Control Optional Piezo Ignitor Millivolt pilot system does not require power Includes pipe to 8' ceiling height Ceramic fiber logs with glowing embers 12 & 16 Gauge Steel Construction Ceramic Glass provides 360 view of fire Can be placed directly on carpet or wood floors Limited 5 Year Warranty Are there red flags I'm missing based on this features list? (Aside from no stated efficiency rating) If we got one of these, would we still need to get another source of heat, i.e. propane furnace or electric baseboard/wall heat? Thanks in advance for your thoughts.
