SOL-ESH D
Solar + Electric + Heat Exchanger
SOL-ESH D Dual-Coil Hybrid Tank
Two independent coils — combine solar with boilers or central heating.
The dual-coil SOL-ESH D accepts two heat sources at once: a solar circuit on the lower coil and a boiler or central-heating circuit on the upper coil, with the electric element as final backup. The most flexible platform in the SOLARIX range for villas and multi-source systems.

Product overview
The dual-coil SOL-ESH D accepts two heat sources at once: a solar circuit on the lower coil and a boiler or central-heating circuit on the upper coil, with the electric element as final backup. The most flexible platform in the SOLARIX range for villas and multi-source systems.
In this series the solar circuit is completely sealed: heat passes into the stored water through an internal heat-exchanger coil rather than by direct mixing. The closed-loop design keeps lime scale and impurities out of the collector circuit — especially valuable in hard-water regions.
The sealed loop can also be filled with antifreeze fluid, enabling reliable operation in climates where winter temperatures drop below freezing. As across the whole SOLARIX hybrid range, the thermostat-controlled electric element remains permanently on standby, guaranteeing hot water regardless of the weather.

Engineering features
What sets this series apart — from tank construction to everyday operation.
Dual heat sources
Solar on the lower coil, boiler or central heating on the upper — simultaneously.
Closed-loop protection
Both coils run sealed circuits — scale-free and frost-protectable.
Villa & multi-source ready
The flexible choice for premium homes with mixed heating infrastructure.
Electric final backup
Hot water guaranteed even with both external circuits offline.
How the system works
From energy source to hot tap — the complete path of heat through the system.
Sunlight
Free solar radiation reaches the collector surface.
Solar collector
The collector absorbs solar energy and transfers it into the circuit.
Heat-exchanger coil
A sealed internal coil passes heat into the water — scale stays out of the circuit.
Storage tank
The enamel-coated, insulated tank stores hot water with minimal loss.
Hot water outlet
Stable hot water at every tap, whenever it is needed.
The electric element engages automatically whenever solar input is insufficient — hot water is never interrupted.
- Solar heat enters the tank through a sealed coil, so the collector circuit never touches domestic water and stays free of lime scale.
- The closed loop can run on antifreeze fluid, keeping the system safe and productive through freezing winters.
- The electric element remains on permanent standby, guaranteeing hot water in any season and any weather.
