100l indirect water heater SGW(L) with double coil, enameled, polyurethane foam, horizontal 21-104800

Double-coil heat exchanger – efficient DHW heating

This horizontal DHW heat exchanger with a double “U” coil is an efficient solution for preparing domestic hot water in central heating systems. The construction with an enameled tank and polyurethane foam insulation provides long-lasting protection against corrosion and minimizes heat loss, resulting in energy savings. The heat exchanger works with various types of boilers – oil, gas, solid fuel and others, making it a universal choice for installers and end-users.

Design and application

The SGW(L) heat exchanger is designed for horizontal mounting and is characterized by an increased heating surface thanks to the use of a double coil. DHW connections located in the upper and lower part of the tank facilitate installation and ensure ease of use. Additionally, the bottom of the tank contains central heating connections, a socket for the boiler sensor and a socket for the circulation pump, simplifying integration with the existing heating system. The EXTRA GLASS® ceramic enamel applied by the “wet” method is an effective anti-corrosion barrier, and additional protection is provided by a magnesium anode (replaceable).

Advantages for the installer and user

• High efficiency: The double “U” coil ensures fast heating of domestic hot water, reducing the waiting time for hot water.
• Energy saving: A thick layer of polyurethane foam minimizes heat loss, reducing operating costs.
• Durability: EXTRA GLASS® ceramic enamel and a magnesium anode protect against corrosion, extending the life of the device.
• Versatility: Compatibility with various types of boilers means that the heat exchanger can be used in different heating installations.
• Easy installation: DHW, central heating connections, a sensor socket and a circulation pump socket facilitate installation and integration with the heating system.
• Safety: Anti-corrosion protection and the possibility of using an active titanium anode (optional) ensure safe use for a long time.

Technical specifications (for professionals)

The SGW(L) heat exchanger is available in various capacities (80l, 100l, 120l, 140l), allowing you to choose the appropriate model to meet individual user needs. The maximum working pressure of the tank is 0.6 MPa, and the maximum working temperature is 95°C (tank) and 110°C (heat exchanger). The central heating exchanger surface area is 0.38m² for a capacity of 100l, and its capacity is 3 liters. The heat exchanger power at temperatures of 70/10/45°C is 9.15 kW with a flow rate of 220 l/h, and at 80/10/45°C, respectively, 10.4 kW and 257 l/h. These values may vary depending on the selected heat exchanger capacity – detailed data can be found in the manufacturer's technical specification tables (available separately).
