Our research shows that the most efficient and economical way to reduce energy consumption for showers, is to extract energy from the "grey" waste water.
This recycled energy is then used to pre-heat the incoming cold water.
The time for the incoming cold water to start heating is extremely quick and so it starts paying for itself almost instantly.
Energy Drain can recover 40 - 45% of the heat from the wastewater and save power on hot water heating in the process.
Installation is very simple. The connections of the Energy Drain fit most standard waste pipes.
The Energy Drain is simply installed in a shower waste pipe and transfers the heat from the waste "grey" water to the incoming mains cold water without direct contact.
The Energy Drain Heat Recovery system's unique design utilises a patented tube known as Spirex tubing.
In our unique design, the heat is transferred through the space between the inner and outer tubes, so the waste water and the incoming pre-heated potable water never touch.
I've found the Vaportec products to be efficient & fit for purpose and would recommend them when suited for a particular application.
