Vertical DHW heat exchanger with spiral coil 1m2, connections upwards SWK-120 10.5.09.002.01

Energy-efficient solution for domestic hot water heating

The standing DHW heat exchanger with a spiral coil is an efficient device designed for preparing domestic hot water in homes and buildings. The construction with upward-facing connections facilitates installation, especially under wall-mounted central heating boilers, saving valuable space. This is a solid choice for installers looking for a reliable component and for end-users who want comfort and savings.

Construction and performance

The SWK heat exchanger is characterized by high efficiency thanks to a spiral coil with an area of 1 m², which ensures fast and even heat transfer. The tank is made of steel, protected by an enameled coating, guaranteeing durability and corrosion resistance. Additional protection is provided by a magnesium anode, which protects against electrochemical corrosion. PUR foam insulation with a thickness of 65 mm minimizes heat loss, resulting in lower operating costs. Energy class A+++ confirms the high efficiency of the device.

Installation and application

The upward-facing connections significantly facilitate the installation of the heat exchanger, especially in tight spaces. The device is designed to work with central heating boilers and optionally with electric heaters with powers of 1.4 kW, 2.0 kW, 3.0 kW or 4.5 kW (available separately). Thanks to its versatility, the heat exchanger will be suitable for both new installations and for the modernization of existing heating systems. The nominal diameter of the circulation pipe is 3/4 inch (20), which ensures compatibility with most installations. The tank capacity is 120 liters – an optimal choice for households with moderate hot water demand. The dimensions of the device (595 mm wide, 1018 mm high and 595 mm deep) allow it to be adapted to different room arrangements.
