3E Flow system

The 3E Flow system consists of two parts, a Flow-Controller located at the supply manifold and a Tap-Controller located under the tap or other outlet. 3E Flow has developed a system that ensures pipes are empty when not in use. When a tap is opened water is supplied instantly to the tap. This means pipes are empty 99% of the time.

3eflow works by drawing water out of the pipe when a tap is turned off, returning it to the tank or heat exchanger. The instant a tap is opened water is delivered directly to the spout. This happens so quickly the effect is instant hot or cold water, to the tap without delay and without spitting or water hammer.


3eflow is quick and easy to install. It is best suited for new developments or renovations where the plumbing system is to be replaced. 3eflow can be integrated into any plastic piping system for example, PEX pipe-in-pipe. It can be installed with any kind of tap or shower, regardless of manufacturer and is suitable for all hot water systems, tank fed or instantaneous, such as a plate heat exchanger. 3eflow has been developed in cooperation with authorised HVAC installers following industry standards on safe water. 3eflow technology provides benefits and savings for all stakeholders including tenants, property owners, builders and society on the whole.
