TECHNICAL INFORMATION TERMO Combi Cylinder Tank-In-Tank System using solar energy for hot water and heating support. For integration into the heating circuit as return flow booster or hydraulic compensator. Available in two sizes 700 l (160 l domestic water storage) and 1000 l (230 l domestic water storage). Flow Flue for effective potable water heating and to reinforce thermal stratification in the buffer storage. Minimal Heat Losses thanks to tightly fitting, CFC-free 120-mm polyester fiber fleece jacket insulation, tight 150-mm strong cover lid and 50-/30-mm floor insulation with scratch and impact resistant polystyrene shell. Optional Convection Brake CONVECTROL III Technically and hydro dynamically optimized barriers separate the water that cooled in the pipes safely from the hot storage tank water. Heat losses at pipe connections thus are reduced by up to 50 %. Optional Mounting Kit for Solar Station Mounting kit for the solar circuit unit with minimized pipe work. Time and space-saving, clear visual appearance. Double Corrosion Protection with high-quality and durable enamel and magnesium protection anode (option: maintenance free impressed current anode). Quick Installation with flat-sealing screw connections, sensor terminal strip, heat insulation with hook ratchet closure; CONVECTROL III and horizontal installation of the connection pipes. Stable Thermal Stratification due to stabilized cold water inlet and inflow brakes in the buffer storage. High Quality thanks to high-grade and environmentally friendly materials. Produced and inspected in Germany according to DIN 4753 and DIN ENV 12977-3. Options for circulation line, electrical immersion heater and cleaning flange.

Single storage system with combination cylinder TERMO, a pellet boiler and a hydronic mixed heating circuit. The combination cylinder is integrated into the heating system like a hydraulic bypass. The buffer volume of the TERMO reduces partial load operation and irregular clocking of the pellet boiler.

Single storage system with combi cylinder TERMO, an oil or gas boiler or a solid fuel boiler. During solid fuel operation mode, the relay RL is used to switch valve Vr to position AB-A, and the entire combination cylinder is loaded. The oil/gas boiler is then circumvented via valve V3. During oil/gas operation mode and sufficient solar energy, the heating return is routed through the combi cylinder. To achieve this, the three-way switching valve Vr switches from position AB-B to AB-A. The oil/gas boiler then has to supply much less heat or none at all.
