Caveats on Cooling, Swamp FashionEvaporative cooling works finest when the humidity is low. Because the moisture content of the air increases, the evaporation course of slows significantly. And, although swamp coolers use far much less energy, they use great quantities of water, which might be a deal-breaker in water-strapped areas of the world.
The heat shingles melt the snow that covers them, and that water runs down the roof, under the snowpack that lies on high of the roof. Because the water reaches the roof edge, there is no longer any heat from beneath to heat the shingles and sustain the melting course of.
