Renewability Power Pipe

I recently had the opportunity to speak with a representative from RenewABILTY Energy Inc. about how their domestic hot water recovery(DHWR)system differs from others on the market.

Among the striking differences are the technical sheets that specify the efficiency of the pipe given it's length and diameter.
For those of you not familiar with DHWR the idea is that you recapture heat from flowing water before it exits the structrure to the sewer system. The two goals of the system are to recapture heat which is a function of surface area in contact with the incoming cold water and optimize heat transfer while maintaining flow rate.

The PowerPipe solves these issues by adding multiple concentric pipes around the exiting waste water and pre heating cold water destined for the hot water heater.

This is a product that in the $500-$1000 price range installed should be added to every new building that has a significant hot water use.
