Another HXdrain find its way into the very latest of smarthouses in Norway as reported by tu.no .
VXpipe and HXdrain is used to make this passivhouse into a smarthouse. http://www.tu.no/bygg/2015/12/08/slik-gjorde-han-passivhuset-til-et-smarthus.-og-snart-blir-det-et-plusshus
We have recently made some adjustments to the milling program at Ny Plast and are delighted to receive another batch of HeatSnagger enclosures. This will cut production time and we will be able to have shorter delivery times. Most every unit the last half year has been exported.

HXtray – shower tray with DWHR
In the course of 2012 and 2013 we have sold most of the Heatsnaggers from our first series. Due to the increasing interest in our simple and cheap DWHR unit for shower, we decided to order parts for a new batch. These include the vacuum formed parts for the mainbody and the lid, the pipe assembly and same small parts like screws and special glue. All these parts arrived from our suppliers the last weeks, and we started production. These new units will be sold in our webshop and through our distributors.
We have also received test documentation from our pipe supplier. The pipes have a maximum operating pressure of 40 bar (580 psi), and are all pressure tested to 35 bar (508 psi) . Two units were actually tested until they bursted. That was at a pressure of 223 bar (3234 psi)!
ASV Solar in Holmestrand Norway is setting up a showroom for our drain water heat recovery products. They are adding new products to their Energy Center where you are welcome to see their solar collectors and now also a range of other energy saving products. You may also buy our products here. If you are passing by on E-18 it is only a short detour to visit ASV Solar at Bentsrudveien 8.
At the fair October 17-19 we where showing VXpipe, HXdrain and HeatSnagger. This is the first time such a range of drain water heat recovery products have been shown at this biannual fair in Norway. We had a lot of visits to our stand. The HeatSnagger is an eye catcher, but most professionals want maximum performance and where impressed with the possibility to recover about half of the energy when showering using the VXpipe or HXdrain. VXpipe is an established product with many thousand units sold in Europe, and has a competitive price tag. HXdrain is a newer product and currently more expensive, but we got the best press coverage for the HXdrain (Norwegian).
The Miljødusj DWHR unit has been on the Norwegian market since 2008. The concept is the same as for our HeatSnagger: a DWHR unit intended to be placed under a showercabinet. The units are produced by SUP Technology in the Czech Republic and are sold in Norway through a webshop .
We were very interested how the performance of Miljødusj compares to our HeatSnagger, so we obtained a used unit, opened it, cleaned it and put it to the test in our lab.
As with the HeatSnagger, we measured the temperature rise of the cold water in a balanced flow setup (dTcold). From these numbers we calculated the power of the heat exchanger (Phe).
The curves compare the Miljødusj performance with HeatSnagger (HS) for both the temperature rise and power versus water flow.
It turns out that the curves are virtually on top of each other, meaning that the performances of Miljødusj and HeatSnagger are pretty much the same.
