Hei-tech, heat exchangers

Hei-tech heat exchangers win back heat from shower water, it is eco friendly and saves costs up to 60% on your energy usage.

Hotwater loss becomes hotwater profit!

During a shower, a lot of heat goes straight down the drain along with the shower water. The heat exchangers Hei-tech has developed heat up the tap water on its way to the shower using the waste water that is on its way down the drain.


A relatively small investment can lead to a major saving in energy which means the heat exchanger pays for itself inside a couple of years.

The heat exchangers can be used everywhere where hot water runs into a drain. I.e. in homes, apartments, retirement homes, hotels, swimming pools and sports facilities. They can also be implemented in industrial processes which discharge warm waste water. A very efficient application is reclaiming heat from the waste water of dishwashers in hotels, restaurants, retirement homes, etc.

There are several different versions of the heat exchangers available.
