This week we have been to the Netherlands and tested the HeatSnagger at KIWA according to the standard NEN 5128 A1:2009 which prescribes performance testing for DWHR systems for shower. The test uses a 40°C input drain water temperature, 10°C cold water temperature and two flow settings, respectively 9.2l/min and 12.5l/min. The flow is balanced …
We have had a great day at Ny Plast where we joined in on the production start up of the HeatSnagger. We made some final adjustments on the drain pipe. On request from several plumbers, we have changed it to a coupling in stead of just a plain 40mm pipe. This will reduce installation time and …
From the lab: Using the setup described in one of the previous news items, we have carried out performance measurements on one of our HeatSnagger prototypes. This was done for both unbalanced and balanced setup, and for different flow rates. (For an explanation of the difference between balanced and unbalanced, please refer to our page …

We have seen some interest for branding the HeatSnagger, so we decided to remove the Meander logo that was originally designed to be on the top lid. Instead we added arrows to guide installation of the unit. The arrows show how to connect the pipes to achieve counter flow of gray water and cold water. …
The HeatSnagger is a basic drain water heat recovery unit for a shower cabinet. The focus of the design has been a good price-performance ratio. Inside the HeatSnagger you find a 3 m copper pipe where the cold water to the shower mixer flows. It is a normal copper pipe bent in a meander …
To verify the performance of the first prototypes of our DWHR product, we built a test setup in the basement of Arthur’s house. Its main components are an electric hot water tank, a shower platform and a PC based multi-channel logging tool. The heat exchanger unit is placed directly under the shower platform and connected …
Before the summer we found the time right to send in our patent application to the Patent Office. It will be some time before we can anticipate the approved Patent. For now our product is “Patent Pending”
Most of the production tools for the DWHR unit are now ready. Vidar Fagereng at Ny Plast is demonstrating the principles of the two molds. In his hands he is holding the top piston mold that is needed to help push the heated plastic sheet into the bottom mold prior to applying vacuum suction to it. With the …
