Storage water heater Galmet SGW(L)P E80L horizontal double-jacket 80 L with yellow polyurethane insulation

Galmet SGW(L)P E80L horizontal double-jacket storage water heater offers 80 litres of usable hot water capacity in a compact horizontal design. The appliance features a double-jacket construction with an external jacket that serves as a secondary circuit for heat exchange and improved thermal stability. Yellow polyurethane insulation reduces standby heat loss and helps maintain temperature when the heater is connected to central heating or an external heat source. The product is intended for domestic hot water supply and can be installed in boiler rooms, utility spaces or similar technical locations.

Advantages

The double-jacket design allows indirect heating via a secondary circuit, enabling efficient heat transfer from a boiler or other heat source while isolating potable water from the heating medium. The yellow polyurethane insulation provides effective thermal protection across the tank surface to reduce energy losses. A horizontal layout is space-efficient in installations with limited vertical clearance and simplifies connection to horizontal piping runs. The 80 L capacity balances hot water storage and compact footprint for typical household needs.

Suitable for

• Domestic hot water supply in homes and apartments
• Connection to central heating systems or external heat sources
• Installation in boiler rooms, utility rooms or under-sink technical spaces
• Retrofitting where horizontal mounting and moderate storage volume are required

Key specifications

• Storage capacity: 80 litres
• Orientation: horizontal
• Construction: double-jacket (secondary jacket for heat exchange)
• Insulation: yellow polyurethane foam
• Application: indirect hot water heating (requires external heat source)

How to use

Install the water heater according to local regulations and the manufacturer's installation instructions, ensuring secure horizontal mounting and adequate clearance for piping and maintenance. Connect the secondary jacket to the external heat source or central heating circuit using appropriate fittings and valves; connect potable water inlet and hot water outlet to the building plumbing. Commission the system by filling and venting both the potable and secondary circuits, then gradually bringing the heat source up to operating temperature while checking for leaks and correct flow. Regularly inspect pressure and safety devices and monitor insulation integrity to maintain thermal performance.

Usage recommendations

To maximize efficiency and service life, ensure correct hydraulic balancing of the secondary circuit, maintain recommended operating pressures, and schedule periodic inspections for corrosion protection and heater connections. Use appropriate safety valves and expansion vessels as required by the heating system design.
