ELDOM thermoelectric boiler 1000L

The ELDOM 1000L thermal storage tank is a large-capacity buffer vessel designed to accumulate thermal energy in heating systems with one or multiple heat sources. It is ideal for large private homes, cottages, and commercial facilities where efficient use of energy from boilers, heat pumps, and renewable sources is essential.

Purpose and role in the heating system

ELDOM 1000L functions as a heat accumulator:
it absorbs excess heat from heating equipment and gradually releases it into the system, smoothing peak loads, reducing boiler cycling, and extending equipment lifespan.

Important: the tank is not enamelled, which means it is intended exclusively for heating systems and not for producing potable or sanitary hot water.
It is used as a buffer between the boiler/heat pump and the radiator or underfloor heating system. For DHW, a separate indirect heating boiler must be used.

Construction and materials

The outer casing is made of durable synthetic INOX-colored material that:

▪️ resists scratches and mechanical damage;
▪️ maintains its clean appearance in the boiler room;
▪️ is unaffected by humidity.

The inner tank is designed to operate with heating fluid (water or antifreeze) circulating through the system. Its construction offers high reliability and resistance to thermal stress.

Energy efficiency and insulation

One of the key advantages of ELDOM 1000L is its advanced insulation:

▪️ freon-free high-density HFO polyurethane foam;
▪️ insulation thickness — 80 mm;
▪️ closed-cell structure.

This results in minimal heat loss and long-term heat retention, allowing:

▪️ reduced fuel and electricity consumption;
▪️ optimal use of solid-fuel boilers, which should not be cycled frequently;
▪️ efficient integration with renewable energy sources.

Connection and control

The tank includes multiple connection ports, providing installation flexibility:

▪️ connection to boilers (solid-fuel, gas, electric, pellet);
▪️ integration with heat pumps;
▪️ compatibility with solar collectors and other heat sources;
▪️ connection of multiple heating circuits.

Additional features:

▪️ ports for temperature sensors for integration with automation systems;
▪️ internal sensor connector for precise temperature transmission to the controller or boiler automation;
▪️ temperature indicator for easy visual monitoring.

The tank also provides a mounting option for an auxiliary electric heating element (TEN), which can serve as a backup or additional heat source.

Features and advantages

▪️ floor-standing model, convenient for installation in boiler rooms;
▪️ compatible with several alternative heat sources simultaneously;
▪️ ideal for solid-fuel boiler systems where heat accumulation is crucial;
▪️ improves comfort, stabilizes temperature, and reduces heating costs.
