Construction of a central heating boiler

Draft regulator

Depending on the temperature of the medium, it controls the flap regulating the air flow to the boiler combustion chamber.

Mechanical thermometer

Mechanical bimetallic thermometer, equipped with a long measuring probe.

Swirlers

Swirlers are a solution that:

  • Increases heat exchange efficiency - swirlers cause turbulence in the exhaust gases, which improves heat transfer to the water jacket.
  • Reduces fuel consumption - better heat exchange means lower energy losses and more economical operation of the boiler.

Horizontal convection channels | shelf

Effective design adapted for automatic cleaning of the exchanger from the front. The construction of the boiler exchanger ensures high heat collection from the furnace.

Flue outlet at the back of the boiler

The boiler design has been designed in such a way that the flue outlet is located at the back of the boiler. The use of such a solution allows for the flue outlet to be directly led out to the chimney.

Secondary and primary air intake

Air is drawn in through six holes to fully burn the fuel. The amount of secondary and primary air can be adjusted using sliders.

Smoke extraction flap

It allows for effective removal of smoke from the combustion chamber depending on the user's needs.

Ceramic plates

The use of ceramic plates in the combustion chamber improves the efficiency of the combustion process. The screens increase the temperature in the combustion chamber and stop particles floating in the furnace, burning them. The thermal efficiency of the boiler increases, and the exhaust gases have the amount of compounds harmful to the environment reduced to a minimum.

Buffer tank

(Additional equipment)

Ensures optimal operating conditions for the boiler. The boiler can operate at optimal power, and excess heat is stored in the buffer. The home heating system draws as much heat from the buffer as it needs at a given moment.

Note! The central heating boiler can be installed in the heating system only together with a buffer tank. The tank is not included in the price of the boiler.

ATTENTION!
Any interference with the boiler’s design is prohibited and will void the warranty. Attempts to install additional grates or components that allow the combustion of fuels other than those specified by the manufacturer are prohibited.

Ecology and savings

Wood gasification is an environmentally friendly process that allows for maximum use of energy from a renewable fuel source, which is wood. The high efficiency of the boiler translates into lower raw material consumption, and thus into real savings in heating costs. The ecological nature of wood and limited emission of pollutants make choosing this boiler an investment in clean air and the future of your home and surroundings.

Gasification chamber

The SEMAX BASIC boiler uses a gasification and combustion chamber, which is responsible for the effective thermal processing of wood. The supplied primary and secondary air can be regulated, which allows for full combustion of the fuel. Ceramic plates are used in the combustion chamber, which improve the efficiency of the process by raising the temperature and stopping particles floating above the furnace. As a result, the obtained thermal energy is used to the maximum, and the emission of harmful substances is reduced to a minimum. The gasification chamber, combined with a refined wood gas combustion system, guarantees stable operation of the boiler throughout its service life.

Controls

The wood gasification boiler does not require complicated automation, it can be equipped with a simple, intuitive control system that allows monitoring of operating parameters. A mechanical bimetallic thermometer ensures long and reliable measurement work, and the draft regulator takes care of the appropriate air supply. Thanks to well-thought-out solutions, boiler control is simple, and the combustion process is stable and safe.

Controls

Thrust ruler

The use of a draft regulator in the SEMAX BASIC boiler is a key element in controlling the wood gasification process and the combustion of the obtained wood gas. This device allows for manual regulation of the flap supplying air to the combustion chamber, maintaining the set temperature of the heating medium. The regulation of the amount of secondary air is possible thanks to special slides. Simple, mechanical regulation ensures easy adjustment of the boiler operation to the current thermal needs of the building and enables stable, effective and economical wood gasification.
