KOSPEL SWK-120 combined water heater 111 l, floor-standing, 1.0 m² heat exchanger

KOSPEL SWK-120 indirect combined water heater, floor-standing, 111 l, 1.0 m² coil

KOSPEL SWK-120 is a floor-standing domestic hot water cylinder equipped with a spiral heating coil. It offers an actual storage capacity of 111 litres and a 1.0 m² heat exchanger surface, providing efficient heat transfer from a central heating boiler or another suitable heating source.

The main hydraulic connections are positioned on the top of the cylinder, making the SWK particularly suitable for installation directly below a wall-mounted heating boiler and helping to save valuable installation space.

The spiral coil provides up to 30 kW heat exchanger output under the manufacturer's specified 80/10/45 °C operating conditions with a heating-water flow rate of 2.5 m³/h.

A 65 mm PUR foam insulation layer helps minimise heat losses. The SWK-120 has standby heat losses of only 36 W and an A energy efficiency class.

The steel cylinder is protected against corrosion by a high-quality enamel coating and a magnesium anode. KOSPEL states that every cylinder undergoes leak testing and inspection of the enamel coating during production.

The unit includes a thermometer, temperature sensor pocket, circulation connection and a dedicated connection for an optional electric immersion heater.

The electric immersion heater is not included as standard. Compatible KOSPEL GRW heaters are available in 1.4, 2.0 and 3.0 kW versions for 230 V, as well as a 4.5 kW version for 400 V.

KOSPEL SWK-120 is a compact solution for homes requiring efficient domestic hot water storage, a high-performance spiral coil and the option of supplementary electric water heating.

Important: the stated 30 kW coil output applies at 80/10/45 °C and a heating-water flow rate of 2.5 m³/h. Actual output depends on operating temperatures and flow rate.
