We have asked our customers to write their experiences by installing and using shower exchanger NELA. Here is one of them:
Peter J. (Sweden), buy 5/2016:
I have very good experiences from using NELA and we are very happy with this. The incoming “cold” water still holds 20-22C rather than the raw 7-8C.The installation was quite easy. We just had to make sure we had the additional hose with the correct size connections.NELA has definitely helped us save on the hot water bills as well as made us feel that we are a little bit friendlier towards the environment when we shower.
