Waste Heat Recovery

for Homes and Buildings


Drainergy   HeatBank   HeatClamp

Water takes more energy to heat than any other material. Everyone in every building everywhere uses hot water everyday. The cost ($50 billion+) to buy energy at these ‘peak power demand’ times is enormous. Then it all drain away, the energy too.


Drainergy, HeatBank and HeatClamp are solutions to that waste. They also lower the cost of living, cost of commerce, global warming, pollution and smog. They shave peak power, transmission losses, and, provide more hot water much faster.
