HEAT RECOVERY EXPERTS

Since 2009, EHTech has been developing heat recovery systems.

In 2011, the team launched Obox, the most efficient heat recovery unit ever tested by an independent laboratory. Seven years later, no system has yet equaled this record.

Wastewater is a formidable source of heat and the Obox heat recovery units from EH Tech can capture up to 80%.
Disposing of hot water down the drain remains standard practice today. Wastewater heat recovery is gaining more recognition, because it is the most logical, economical and environmentally friendly way to heat water.

EHTech perfectly masters the design of high-performance exchangers and the automated maintenance of their performance over time, even under extreme conditions of use.

Our Obox systems are installed in:

• The houses
• Pools
• Aquatic centers
• Sports halls
• Hair salons
• Buildings / Hotels
• Industries
