Product Overview

The SBP range of freestanding cylinders offer an ideal interface and collecting point for even the most diverse heating systems. This not only saves a lot of space, but also saves energy. With the SOL versions, it is also possible to integrate a solar thermal system.

Product Details

Buffer cylinder for heating heat pumps in large systems. The cylinder enables hydraulic separation between the heat pump and heating circuit flows, extends the operating time of the heat pump and stores heating energy. Suitable for use in apartment buildings and commercial buildings.

Convenience features
Steel cylinder with 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 a 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 also equipped with an internal smooth tube solar indirect coil.

Low standby losses in conjunction with the high-grade thermal insulation as an accessory. Good temperature stratification due to matched inlet and outlet technology. Designed for connecting heat pumps with high flow rates on the primary side.
