ELDOM thermoelectric boiler 500L

The ELDOM 500L thermal storage tank is a compact yet capacious buffer vessel designed for heating systems in private homes, townhouses, small cottages, and facilities with moderate heat demand. It efficiently stores thermal energy and redistributes it within the heating system, reducing peak loads on the equipment.

Purpose and usage specifics

ELDOM 500L is used within heating systems as:

▪️ a heat accumulator for solid-fuel boilers;
▪️ a buffer tank for heat pumps operating in optimal continuous mode;
▪️ an energy storage tank for solar collectors and other renewable sources.

The tank is not enamelled, meaning it is not intended for domestic hot water production. It works only with heating fluid circulating in heating circuits, while DHW requires a separate boiler.

Construction and appearance

The outer casing is made of highly durable synthetic material in INOX color, providing:

▪️ scratch and impact resistance;
▪️ a clean, modern look suitable for boiler rooms;
▪️ ease of installation and maintenance.

Compact dimensions for its capacity allow installation even in limited spaces.

High energy efficiency

ELDOM 500L features a thick insulation layer:

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

As a result, the heat stored in the tank remains for an extended period, reducing fuel and electricity consumption and increasing overall system efficiency.

Connections, sensors, and control

The tank includes:

▪️ multiple ports for supply/return lines, heating circuits, and auxiliary equipment;
▪️ sensor ports for integration with heating controllers and automation;
▪️ a sensor connector with an installed temperature probe for accurate communication with the control system;
▪️ a temperature indicator for visual monitoring.

The tank also includes a mount for an additional electric heating element, allowing the TEN to serve as a backup or night-tariff heat source.

Applications and advantages

ELDOM 500L is optimal for:

▪️ medium-sized private homes;
▪️ solid-fuel boiler systems requiring heat accumulation;
▪️ hybrid configurations (boiler + heat pump + solar collectors);
▪️ upgrading existing heating systems to improve efficiency.

Key advantages:

▪️ stable floor-standing design;
▪️ compatibility with multiple alternative heat sources;
▪️ reduced boiler wear thanks to fewer start cycles;
▪️ improved comfort and more stable indoor temperatures.
