Power of which

The height of the chimney is determined by several factors — these are features of the design itself, the power of the boiler, the cross section of the channel. For a boiler with a capacity of 15 kilowatts, the height of the output is at least 6 meters, for a heat generator, the power of which is twice, the height of the chimney is determined in 10 meters. In any option, the height should not be below 5 meters.
