Recommended water hardness: 6-7 °dH - if the water is harder, integrate a water softener that uses the ion exchange principle into the feed pipe.
For the optimum choice of hot water storage device - taking into consideration additional drawing-off points and the frequency with which RainSky M is used - the specific demand needs to be assessed. Recommendation: storage capacity of at least 500 l.
For choosing the drainage, taking into consideration the discharge of all the products in the shower, the specific demand needs to be assessed. Recommendation: Floor drain (connected rating) = 1,5 l/sec, drainage rate DN 70
Feed pipe (hot/cold): 2 x DN 20
