Evaluation performed by: Electric Power Research Institute. While the technology itself is fairly well understood, the actual performance of HPWH systems has not been quantified in sufficient numbers. This demonstration aims to provide that quantification. The variation of system efficiency with climate, water usage, and installation location are being examined.
