Hot Water Instantly without energy loss!

Who are we?

3eflow has developed a system that ensures pipes are empty when not in use. When the tap is opened, water is supplied instantly to the spout.

What’s special?

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

Hence, there will be no more waiting around for hot water, correct temperature from the first drop. It stops the heat losses and energy costs for hot water cut in half.

Water at the tap is always fully hot and when not in use the pipe empty. Consequently, the environment suited to Legionella propagation is engineered out.

Our vision is to sell our products to manufactures who can add value to their portfolio by incorporating 3eflow’s technology.

What's the challenge?

3eflow has an embedded device that communicates over CANBUS. They want to read from and steer the device via the Internet (via a cloud solution). And that's where you come in, we are looking for a software developer to write software for a Raspberry Pi (with a CANBUS shield) to connect the embedded device to the internet.

About the company

3eflow was founded by Erik Abbing in 2009 after 5 years of study at LTU university for a master of Science degree. Erik founded the company after hearing that the California energy department announced they were actively seeking a solution to the vast amounts of energy and water that is wasted by conventional tap water systems. For Erik, this seemed a natural challenge to undertake as his family has a long-established provenance in the plumbing industry. After many years of research and development, 3eflow holds several patents on the worlds firs intelligent water system that tackles this problem.
