Storage domestic hot water tank KOSPEL SWK-140.A.TERMO-TOP.WHITE with spiral heat exchanger, white
KOSPEL SWK-140.A.TERMO-TOP.WHITE is a vertical standing storage tank designed for domestic hot water (c.w.u.) equipped with an internal spiral heat exchanger. The tank provides stratified hot water storage to maintain temperature layers and allows connection to external heat sources through the integrated coil. Finished in white, the compact cylinder is intended for residential and light commercial installations where space-efficient, wall-adjacent placement and coil integration are required.
The internal spiral heat exchanger ensures efficient heat transfer from an external heat source while reducing the risk of direct mixing between circuit fluids. Stratified storage improves thermal efficiency by preserving layers of differing temperature, which supports faster delivery of hot water at setpoints and reduces cycling of heat sources. The upright design minimizes floor footprint and facilitates installation in utility rooms, basements, or near service walls. The white finish provides a neutral appearance that integrates with typical interior service areas.
Connect the integrated spiral heat exchanger to the external heat source following hydraulic and safety requirements of the heating system. Ensure cold water inlet, hot water outlet and pressure-relief devices are installed according to local codes and manufacturer recommendations. Commission the tank by filling it with water, purging air from the coil and system circuits, then gradually heating to operating temperature while monitoring for leaks and correct flow through the exchanger. Regularly inspect connections, valves and insulation for proper condition.
Locate the tank on a level surface with adequate access for maintenance. Match the coil flow rate and heat source output to the tank capacity to achieve efficient heat exchange; consult installation documentation or a qualified technician for correct pipe sizing, safety devices and control integration. Implement routine inspection of sacrificial anodes (if fitted) and external insulation to prolong service life and maintain thermal performance.
