As a result of its structure, the ROTEX Sanicube Solaris is optimal from a water hygiene perspective, since the water to be heated is passed through to a pipe system and heated. The water content of the domestic water heat exchanger is currently 19/24 litres and is therefore only a fraction of the water quantities usually found in storage tanks. Areas with little current or which are not heated all the way through on the hot water side do not even come into question in the ROTEX Sanicube Solaris.

Domestic water is exclusively located in one pipe so that deposits of sludge, rust or other sediments, as can occur in containers with a large volume, are not possible. The water stored first is also taken out first (First-in-first-out principle).

The outstanding water hygiene advantages of this type of hot water storage tank were confirmed by extensive research carried out by the hygiene institute of Tübingen university.

Legionella Bacteria

There are approx. 35 types of legionella. At least 17 of these are pathogenic. The most common consequences are: Pontiac fever: symptoms similar to flu which improve after a few days. Legionnaire's disease: severe bacterial lung infection. The infection is fatal in 15 to 20 percent of cases.
