Vertical DHW heat exchanger with spiral coil 0.82m2 - connections upwards SWK-100 Termo Top, white 10.5.09.001.01

Energy-efficient DHW heat exchanger for mounting under the boiler

The SWK-100 Termo Top heat exchanger is an efficient device designed for heating domestic hot water in central heating systems. Its construction with a spiral coil with a surface area of 0.82 m² ensures effective heat exchange, and the upward-facing connections allow for convenient installation directly under a hanging central heating boiler, saving valuable space in the boiler room. This solution is appreciated by both installers and users looking for compact and efficient solutions.

Construction and efficiency

The SWK-100 is characterized by a high energy class A, which translates to minimal heat loss – even 50% less compared to older models. The key to this efficiency is the thick PUR foam insulation (65 mm), which effectively limits heat dissipation to the environment. The tank is made of high-quality steel, and additional corrosion protection is provided by a magnesium anode (model AMW.M8.450), which should be regularly checked and replaced (control every 12 months, replacement every 18 months).

Installation and compatibility

The compact dimensions of the device (diameter 595 mm, height 906 mm) and the upper connections facilitate installation, especially in limited spaces. The heat exchanger is compatible with various types of central heating boilers and can be equipped with an electric heating element with a power of 1.4 kW/230V, 2.0 kW/230V, 3.0 kW/230V or 4.5 kW/400V – allowing for flexible adaptation to individual needs. The coil power is 25 kW with standard operating parameters of the installation.

Product information: product code SWK-100.A, capacity 97 liters, coil surface area 0.82 m², rated pressure 0.6 / 1.0 MPa.

Remember to regularly maintain the magnesium anode – this is key to long-term protection against corrosion and reliable operation of the heat exchanger for many years.
