Vertical DHW heat exchanger with spiral coil 1.1m2, connections upwards SWK-140 10.5.09.003.01

DHW heat exchanger with a spiral coil – an effective solution for your system

This standing DHW heat exchanger with a spiral coil is a solid choice for both installers and users looking for a reliable source of domestic hot water. The design with connections pointing upwards facilitates installation, especially under a wall-mounted central heating boiler, saving valuable space in the boiler room. High energy efficiency and durability are features that distinguish this model from the competition.

Construction and performance

The SWK-140 heat exchanger with a capacity of 140 liters has been designed for optimal heat transfer. The spiral coil provides a large heat exchange surface, which translates into fast and efficient water heating. PUR foam insulation with a thickness of 65 mm minimizes heat loss, reducing operating costs by up to 50% compared to older models. The use of an enameled tank coating guarantees corrosion resistance and long-term device reliability.

• The device capacity is 140 liters, making it an ideal solution for households with moderate hot water demand.
• The coil surface area reaches 1.1 m², ensuring efficient heat transfer from the central heating installation to the domestic hot water.
• Insulation made of PUR foam with a thickness of 65 mm effectively reduces heat loss and lowers operating costs.
• The tank made of steel guarantees strength and resistance to high pressure (0.6 MPa).
• The enameled tank coating provides long-term protection against corrosion and extends the life of the device.
• The device is characterized by energy class A+++, which translates into high energy efficiency and lower energy bills.

Installation and application

Connections pointing upwards significantly facilitate the installation of the heat exchanger, especially in tight boiler room spaces or directly under a wall-mounted boiler. The nominal diameter of the circulation pipe is 3/4 inch (20), ensuring compatibility with most standard plumbing installations. The device is designed to work with a central heating boiler, providing constant access to domestic hot water throughout the house. Solid construction and precise workmanship guarantee trouble-free operation for many years. Each heat exchanger undergoes rigorous leak tests and quality control of enamel coatings, confirming its high quality and reliability.
