The ELDOM 100L (1S) thermo-electric indirect heating boiler combines high efficiency, reliability, and versatility, designed for modern domestic hot water systems with the option to connect to alternative energy sources. Thanks to its large volume and advanced technologies, the model ensures a stable supply of hot water for homes, offices, and commercial facilities.
1. Reinforced tank and durable coating
The inner tank is made of heat-resistant steel and coated with zirconium-based enamel that provides:
▪️ resistance to sudden temperature changes;
▪️ excellent adhesion and corrosion protection;
▪️ sanitary safety.
Two magnesium anodes ensure long-term protection of the entire tank volume, preventing corrosion even under intensive use.
2. High-efficiency enlarged heat exchanger
The lower S-type heat exchanger maximizes contact surface with the heat carrier, ensuring:
▪️ fast heating of the 100-liter volume;
▪️ stable temperature even under increased consumption;
▪️ optimal performance with solar panels and heat pumps.
3. Powerful 6-stage protection system
The model includes a comprehensive safety package:
▪️ Zirconium enamel
▪️ Two magnesium anodes
▪️ Capillary safety thermostat
▪️ Combined safety valve
▪️ Overheat protection thermostat
▪️ Anti-freeze protection
In addition, the IP24 moisture protection rating allows safe use in damp environments.
4. Energy savings and reduced heat loss
The thick HFO polyurethane foam insulation significantly reduces heat loss and maintains water temperature for long periods without repeated heating cycles.
This extends the heating element’s service life and minimizes operating costs.
5. New control logic
The modern control panel includes:
▪️ dual LED status indicator;
▪️ power and temperature controller;
▪️ “Holiday” mode;
▪️ precise thermostat;
▪️ sensor connection ports.
These features allow the unit to adapt to any usage scenario.
6. Wide application scenarios
The 100-liter capacity is suitable for:
▪️ families of 2–3 people;
▪️ shower and kitchen zones;
▪️ small commercial facilities.
Its high performance makes it a reliable solution for both residential and corporate hot water supply systems.
