Catalytic Gas Stove for Winter Room Heating: Safety, Exhaust Gas, and Gas Cylinder Efficiency

A catalytic gas stove is not recommended as a main room heater: it burns LPG, consumes room oxygen, adds a lot of water vapor, and therefore needs strong ventilation, so it is better suited to a garage/car park or only temporary use [#5487330][#5487608][#5490858] One user reported that in a 17 m² attic room it used about 1 cylinder per week at 8-10 hours per day, while for additional spring/autumn heating it lasted about 1.5 months; a different stove of the same type used about 1 cylinder per month but heated less well [#5668044] For best efficiency, run it on the highest setting for about 5 minutes to warm the catalyst, then switch to the lowest setting; using the 2nd or 3rd level continuously was described as wasting gas and money [#5668044][#10447474] The stove can also shut off when oxygen becomes too low, and sleeping with it on was described as making breathing difficult, so opening a door or window briefly is better than relying on leaks [#5668044] If you need a safer fixed solution, one reply suggested a boiler with a closed combustion chamber and a radiator through the wall [#5492604]
