Buffer vessels for closed hot water heating systems with a welded-in straight-tube heat exchanger for the hydraulically separated integration of additional heating systems (e.g. the combination of solid fuel boilers with solar systems or similar). Robust and installation-friendly design. Equipped with various sensor connections for the individual adjustment of the temperature control. Foot height adjustment for quick and safe alignment. Powder coated exterior, uncoated interior.
