2.2
Product description
The solar storage tank is equipped with an electric heating element.
Alternatively, the solar storage tank can be operated with a downstream
external tankless water heater.
When operated with an external tankless water heater, the electric
heating element must not be connected.
The main components of the solar storage tank are:
• Storage tank with corrosion protection
The cathodic corrosion protection comprises the hygienic thermo
glaze and two magnesium anodes.
• Smooth tube heat exchanger
The smooth tube heat exchanger transfers the energy from the solar
circuit to the DHW inside the storage tank. The potable water is
heated uniformly.
• Thermal insulation
The thermal insulation, made from CFC-free hard polyurethane foam,
is directly applied to the storage tank and insulates against heat loss.
• Sensor well with DHW temperature sensor
The optional DHW temperature sensor supplies temperature
information to an optional controller.
• Electric heating element
In addition to the solar thermal system, the electric heating element is
a backup heat source for DHW heating.
• Drain valve
The drain valve is used to drain the storage tank completely.
• Temperature and pressure relief valve (TPR)
The temperature and pressure relief valve protects the storage tank
against overheating and overpressure.

2.3
The solar storage tank is used to heat and store potable water to supply
single- and multi-family homes. Please observe national, regional, and
local codes, regulations, guidelines and standards for potable water.
Heat the solar storage tank only by means of a heat transfer medium
(mixing ratio: heat transfer medium/water max 50/50) and only in
closed systems.
Install the solar storage tank only inside a building. The room must not be
exposed to freezing temperatures and the floor must be level.
Observe the specifications (
Any other purpose is considered improper use. Any resulting damage is
excluded from the manufacturer's warranty.
