Saving energy these days is as important as anything that we do to save cash and at the same time the planet, but sometimes we waste energy in the most unexpected ways like through the hot water that pours down the drain every time that we have a bath, shower or use the washing machine.

However, EcoDrain is a heat exchange unit separates wastewater and fresh water; the heated wastewater can go back into the water heater meaning that it uses less energy to keep the water warm for later use.
