The ELDOM 150L (1S) thermo-electric indirect heating boiler is a high-power, high-performance model designed for large homes, hotels, cafés, sports facilities, and systems requiring a large and stable hot water reserve.
1. Durable construction and complete protection
The thick-walled steel tank is coated with zirconium enamel, resistant to:
▪️ high temperatures;
▪️ pressure fluctuations;
▪️ the chemical effects of water.
Two powerful magnesium anodes provide uniform cathodic protection throughout the entire tank volume.
2. Maximum heat exchange efficiency
The enlarged lower heat exchanger transfers heat from low-temperature systems significantly faster than standard models. The extended contact surface ensures:
▪️ accelerated heating of the full 150 liters;
▪️ uniform temperature distribution;
▪️ compatibility with the most energy-efficient systems.
3. Intelligent safety system
The six-stage protection package includes:
▪️ thermal protection;
▪️ temperature sensors;
▪️ frost protection;
▪️ combined safety valve;
▪️ IP24 moisture protection;
▪️ reinforced flange.
This makes the model safe in all operating conditions.
4. Maximum energy efficiency
The 35-mm insulation minimizes heat loss, allowing energy savings even when heating large volumes. As a result, the boiler operates longer without frequent reheating cycles and maintains a stable temperature for many hours.
5. Full automation and user-friendly control
The unit is equipped with:
▪️ dual LED indicator;
▪️ combined power regulator;
▪️ “Holiday” mode;
▪️ external capillary thermostat;
▪️ temperature indicator;
▪️ sensor ports.
The latest-generation heating element ensures stable and fast heating.
6. Application
The 150-liter model is ideal for:
▪️ families of 4–6 people;
▪️ large houses;
▪️ small hotels and guesthouses;
▪️ service-sector facilities;
▪️ systems with multiple bathrooms.
