Electric Boilers – Modern, Efficient, and Safe Heating

BalkanEnergy offers high-efficiency electric boilers, with a primary focus on its own brand Balkan Energy, but the catalog also includes products from other leading brands. The boilers can be used as a main heating device or in combination with an existing boiler or fireplace. When combined with a buffer tank, they ensure comfortable and cost-effective heating throughout the entire heating season, while the frost protection function maintains a suitable temperature in your home even when you are away.

These boilers are an ideal solution for heating homes, apartments, offices, and larger buildings. They are suitable for both new constructions and modernization of existing heating systems, especially in areas without access to gas.

How an Electric Boiler Works

The electric boiler generates heat by passing an electric current through water or a resistive heating element immersed in water. This allows the production of hot water that circulates through the heating system. Boilers can also be used as a backup heat source for systems operating with renewable energy sources (e.g., heat pumps) or solid fuel boilers in case of fuel supply interruptions.

Advantages of Balkan Energy Electric Boilers

• Easy installation:
  No chimney or flue system required—only an electrical connection.

• Flexible use:
  Can be used as a main heating unit or in combination with existing boilers, fireplaces, or buffer tanks.

• Protection and comfort:
  The “anti-freeze” function maintains a suitable temperature in the home even during long absences.

• Compact and quiet:
  Ideal for all types of premises without noise pollution.

• High efficiency:
  Optimal use of electricity ensures savings and comfort throughout the heating season.

• Eco-friendly and safe:
  No combustion products or harmful emissions.

• Automation:
  Allows precise maintenance of comfortable or standby temperatures.

• Stepwise power regulation:
  Allows operation at different power levels according to heating needs.

• Low operating costs:
  No fuel delivery, storage, or refueling; low installation and maintenance costs.

Example Model – Electric Boiler Balkan Energy VEN-1, 15 kW

This boiler is suitable for heating larger premises or buildings. It offers three power levels – 5 kW, 10 kW, and 15 kW, which can be easily controlled via switches on the front panel. The model can also be connected in three-phase mode for stable operation under high loads.

Bulgarian Manufacturing and European Standards

Balkan Energy boilers are manufactured in Bulgaria using high-quality materials and undergo strict reliability testing. They are certified according to European quality and safety standards and come with a full 2-year warranty.

Energy Efficiency and Savings

Electricity consumption depends on the heat losses of the building. With proper insulation and the use of a room or wall thermostat, the boiler operates economically, automatically maintaining the desired temperature and preventing unnecessary system load. Using night tariffs (where available) and programmable thermostats further reduce costs.

How to Calculate Boiler Power

For an approximate calculation of the required power:

Boiler Power (kW) = Room Area (m²) × P

where P is the power required to compensate for heat losses per 1 m²:

• Old building: 0.1 kW

• Old building with insulation: 0.07 kW

• New building with good insulation: 0.05 kW
   

For the first or top floor, or a detached building, the total area is considered. For a more accurate calculation, factors such as windows, doors, ventilation, and other elements affecting heat loss should be taken into account.

Safety and Maintenance Requirements

• High-quality grounding is mandatory.

• Limescale buildup may occur, reducing heat transfer and accelerating heater wear.

• High electricity costs can be offset by using night tariffs and automatic temperature control programs.
