STH Buffer Cylinder
Application • These buffer cylinders are suitable for heat pump heating systems and can also be used in cooling mode. • Provides hydraulic separation between the heat pump and the heating/cooling circuit, extends heat pump runtimes and stores heating energy. • Suitable for use in family houses, depending on nominal capacity. • In the case of Plus types, it is possible to integrate solar thermal backup.
Convenience features • The steel cylinder with directly applied foam insulation has hydraulic connectors arranged at the front, one above the other. Connectors are also provided for electric threaded immersion heaters if required. • With Plus types, an internal indirect coil enables solar connection. • The cylinder casing consists of the plastic outer jacket, the cylinder cover and a plinth trim.
Efficiency • Low standby losses. • The buffer cylinders are designed for connecting heat pumps with high flow rates on the primary side.
Capacity: 207L to 720L
Classic Buffer Tank
Application • This buffer cylinder provides hydraulic separation between the heat pump and heating/cooling circuit.
Convenience features • The steel cylinder with directly applied foam insulation is equipped with a protective cover and connections at the top for ventilation and draining.
Efficiency • Reduced mixing due to matched inlet and outlet technology.
Capacity: 100L
SBB PLUS Water Cylinder
Application • This DHW cylinder is suitable for heat pump operation in family houses as well as apartment buildings, depending on the nominal capacity and the indirect coil surface area.
Convenience features • The enamelled steel cylinder, with foam insulation applied directly in the plastic jacket, is equipped with a protective anode for additional corrosion protection. • The appliance has an inspection flange and a connector for an electric threaded immersion heater. • The heat pump is connected via an internal indirect coil. • A plug-in dial thermometer is included in the standard delivery. • The cylinder casing consists of a permanently attached plastic jacket and a cylinder cover.
Efficiency • Low standby losses and matched inlet and outlet technology ensure efficient operation.
Capacity: 300L to 500L
SBB Water Cylinder
Application • This DHW cylinder is suitable for heat pump operation in family houses as well as apartment buildings, depending on the nominal capacity and the indirect coil surface area.
Convenience features • The enamelled steel cylinder with directly applied foam insulation is equipped with an inspection flange, T&P valve and a protective anode for additional corrosion protection. • An internal indirect coil for connecting the heat pump is integrated • A plug-in dial thermometer is included in the standard delivery. • The cylinder casing consists of a plastic outer jacket and a cylinder cover. Both can be removed during installation if required.
Capacity: 300L to 500L
SBS Instantaneous Water Cylinder
Application • This combination instantaneous water cylinder makes DHW available. The appliance can be used simultaneously as a buffer cylinder for hydraulic separation between the heat pump and heating circuit, and is also suitable for storing heating energy. • The instantaneous water cylinder is suitable for family houses. If several appliances are hydraulically interconnected, they can be used in apartment buildings.
Convenience features • The steel cylinder is equipped with an integral corrugated pipe indirect coil made of stainless steel. The appliance provides DHW instantaneously. • The connectors facing the front allow system-specific hydraulic connections. • An additional electric threaded immersion heater can be installed via the inspection port if required.
Efficiency • Low standby losses if the thermal insulation available as an accessory is used. • Matched inlet and outlet technology with integral PRO temp-Flow inlets ensures good temperature stratification. This reduces the flow turbulence considerably.
Capacity: 600L to 1500L
SBP Buffer Cylinder
Application • This buffer cylinder is combined with heating heat pumps in a large scale system and is suitable for use in apartment buildings and commercially used buildings. The appliance enables hydraulic separation between the heat pump and heating circuit flows, extends the operating time of the heat pump and stores heating energy.
Convenience features • The steel cylinder has flange connections arranged at the front, one above the other, for the primary and secondary circuit. There is also an additional connector for combination with further heat generators. An additional indirect coil or an electric flanged immersion heater can also be fitted as required for the specific system. For this purpose, a flanged aperture sealed with a blank flange has been integrated. The SOL types are, in addition, equipped with an internal smooth tube solar indirect coil.
Efficiency • Low standby losses in conjunction with the high grade thermal insulation as an accessory. • The matched inlet and outlet technology is responsible for the good temperature stratification. • The buffer cylinder is designed for connecting heat pumps with high flow rates on the primary side.
Capacity: 1000L & 1500L
WDH Water Cylinder Cover
Description • The high grade thermal insulation made from EPS rigid foam is supplied with insulated cover and floor disc. Graphite inserts in the EPS and the fleece ensure minimal heat losses. • The thermal insulation can be optimally adapted to the cylinder thanks to the wedge-shaped cut-outs and the fleece layer. The prepared adhesive joints in the wedge-shaped cut-outs also contribute to this. • The integrated quick-release hook strip makes it easier to attach the thermal insulation.
