Products of the eTherm family were developed for PV surplus power use. The stations use only surplus electricity. This means: the eTherm products do not start until all household consumers, the battery storage and, if applicable, the charging station for the electric car have been served and surplus electricity is...
The eTherm P/C can monitor the storage tank temperature by means of a storage tank temperature sensor (not included in the scope of delivery) and thus serve as an emergency heater even without external energy management. If the storage tank temperature falls below a threshold value (adjustable), the stations start...
The eTherm P/C must not be operated directly with potable water. However, the stations can be connected to potable water storage tanks with internal heat exchangers. In the case of bivalent drinking water storage tanks, the heat exchangers should be connected in series.
By turning 45°, the gravity brake integrated in the ball valve can be set up manually.
Yes, the valves are approved by Deutsches Institut für Bautechnik for use as siphon protection valves for aboveground fuel tanks.
No, the system storage units are optimized for use with Tuxhorn fittings. They are ordered on an object-by-object basis and delivered by drop shipment. Therefore, please allow sufficient delivery time for the systems.
The eTherm S (self-sufficient solution -> plug and play solution for small storage tanks) has a heating rod that is modulated by the controller according to the surplus. Due to the design (heating rod in the storage tank), this system is particularly suitable for small drinking water storage tanks. The...
In solar thermal energy, collectors convert solar radiation into heat, which is transferred through a water-glycol circuit to a hot water or buffer tank. In photovoltaic modules, solar radiation is converted into electrical voltage, which is fed into the building's power grid through an inverter. Photovoltaic power can be converted...
The max. permissible temperature of the medium in the solar flow is short-term at 140°C In the solar return with the pump, the max. permissible medium temperature is at 110°C.
By turning 45°, the gravity brake integrated in the ball valve can be set up manually.
