## Long description

Galmet storage water heater Wymiennik SGW(L)x2 100L with double coil U is a 100-litre domestic hot water storage tank designed to receive heat from two separate primary circuits. The integrated double coil (U) heat exchanger allows connection of two different heat sources such as solar thermal collectors, a boiler and a heat pump, or two boiler circuits. The unit is intended for residential hot water storage and provides a compact solution for efficient heat transfer and stratified storage of potable water.
Advantages
The double coil design ensures flexible connection of two independent heat sources while maintaining efficient heat exchange and clear separation between circuits. A 100-litre capacity balances compact footprint with adequate storage for typical household hot water demands. The product supports effective integration with solar thermal systems and conventional heating equipment, enabling improved system efficiency through staged or parallel heat charging. Materials and construction are chosen for potable water compatibility and long-term thermal performance.
Suitable for
Residential domestic hot water storage in single-family homes
Systems combining solar thermal collectors and a backup boiler or heat pump
Installations that require two separate primary circuits for staged heating
Retrofit projects where compact 100 L storage is needed
Key specifications
Storage volume: 100 litres
Heat exchanger configuration: double coil (U) for two primary circuits
Intended medium: potable domestic hot water
Application: integration with solar collectors, boilers, and heat pumps
Installation type: vertical storage tank for residential systems
How to use
Connect each primary heat source to one of the two coil circuits following hydraulic and safety requirements of the heating system. Ensure all connections, circulation pumps, check valves and safety devices are installed according to local regulations and the system design. For initial commissioning, fill and vent the tank and heat exchanger circuits to remove air pockets, then perform controlled charging with the primary heat sources to establish proper stratification and temperature settings. Routine inspection of connections and anode (if fitted) helps maintain long-term operation.
Usage recommendations
Use a planned sequence for charging the tank from solar collectors and auxiliary heat sources to maximise solar contribution and reduce boiler cycling. Where appropriate, include thermostatic mixing valves to deliver safe tap temperatures and system controls to prioritise renewable heat. Adhere to local plumbing codes and manufacturer guidance during installation and service.
