For a bedroom or a modest living space, the 18\" blue-flame heater does that with 10,000 BTU\/hr and a modulating thermostat that keeps the whole room - not just the wall in front of it - at a steady temperature.\u003c\/p\u003e\u003cp\u003eIt is the gentle-and-even option: no hot spot, no cold corner, just uniformly warmed air.
