First Shower Heat Exchanger 3D model

We have been doing many temperature measurements and flow tests on our DWHR prototypes. This information has now been combined and together with our design team we have completed our first 3D drawing of the shower heat exchanger. Coldwater connects to the ½” fittings, and the graywater connects to the two 40mm drain pipes. We […]

Long term testing of DWHR prototype nr 3

Testing of prototype #3 is now in its 45th week. We have been tracking cold water temperatures at the in- and output of the unit, as well as temperature difference of the drain water. From these temperatures, the performance of the heat exchanger can be calculated. We have noticed a decrease of performance over time.
