Boiler Termo-Tech ELZA 11 kW
ELZA type boilers with retort burner are designed for water central heating systems of open system with gravitational and forced water circulation.
Steel heating boilers ELZA type with automatic fuel feeding system are recommended for work in central heating installations in single-family houses, commercial pavilions, garages and utility rooms.
Advantages of the boiler:
- high efficiency
- automatic operation
- quick and easy to operate
- economic fuel combustion
- smokeless and environmentally friendly combustion
- possibility of connecting a circulation pump and controlling it
Instructions:
- The highest temperature in the boiler must not exceed 85°C
- The maximum allowable working pressure shall not exceed 1,5 bar.
- The boiler operates with overpressure at the flue gas outlet. Combustion air is forced into the combustion chamber by a fan.
- Boilers may be used only in central heating systems of open system with gravitational or forced circulation water secured in accordance with currently binding detailed national or EU regulations (PN-EN 12828+A1:2014-05 Heating systems in buildings - Design of water central heating systems).
Description of boiler construction:
ELZA boiler is made of high quality boiler sheet metal. Equipped with a specially constructed burner made of cast iron, to which fuel is fed from the tank by means of a screw feeder, in upper part there is an outlet water nozzle (supply). On the side of boiler there is a burner feeder with a fuel tank. Whole boiler is insulated with mineral wool and covered with steel sheet.

Dedicated Fuel :
Hard coal type a1 according to PN-EN 303-5:2012, assortment of peas with following parameters:
- granulation 5 - 25mm
- humidity < 11%
- ash content: 2-7%
- volatile matter content: 15-30%
- calorific value > 28 MJ/kg
Type of fuel used has a significant impact on the proper operation of boiler and durability. The use of fuel that doesn't meet the energy parameters required by manufacturer of the boiler reduces efficiency and effectiveness of boiler.
