Carbon dioxide (CO2)

Carbon dioxide is a gas which is produced when materials containing carbon are combusted. Climatic changes occur due to the increase of carbon dioxide in the earth's atmosphere. The increase in the earth's temperature is also called the greenhouse effect. Carbon dioxide can be reduced by reducing fuel consumption.

Carbon monoxide (CO)

A poisonous gas which is produced when materials containing carbon are combusted. Its production is virtually eliminated by correct burner adjustment.

Circulating pump

An electrical water pump, which pumps the heating circuit water to radiators or floor heaters.

CO2

CO2, carbon dioxide, is a gas created in most combustion processes and also, for example, by respiration. This gas is considered one of the causes of the greenhouse effect and the global warming associated with that. It is also the gas converted through photosynthesis in plants into vitally important oxygen (O2). Weishaupt burners and heating systems are - thanks to decades of research and development - highly efficient with very good fuel consumption and very low CO2 emissions.

Combustion air

Combustion air contains up to 21 percent oxygen, which is essential for combustion. 78 percent of the air is nitrogen. About 10 m³ of combustion air is required for the complete combustion of 1 m³ of gas or 1 litre of heating oil.

Combustion gases

Products resulting from the combustion of fuel and air. In the main, carbon dioxide (CO2) and water vapour are produced.

Combustion manager

The sequence of operations in a combustion process is controlled by modern microprocessor technology. There are many advantages for the operator, and it also enable service technicians to carry out their work more purposefully and quickly (Digital burner technology).

Compressor

A heat pump's compressor pressurises the refrigerant in order to achive the temperature level required for heating purposes.

Condensation heat

Additional heat from the flue gases. Condensation occurs when the flue gases cool, resulting in the release of additional energy. This additional potential – based on the calorific value – is about 11 percent for natural gas, 9 percent for LPG, and 7 percent for fuel oil.

Condensed water

If the flue gas cools below a certain temperature threshold, the water vapour contained within it turns to condensed water. The energy produced in this conversion – the condensation heat – can be used.

Condenser

A heat exchanger inside a heat pump. It condenses a refrigerant by releasing energy to a heating system.

Condensing system

Condensing boilers represent the peak of domestic heating technology – benefiting from high energy utilisation, low emissions, reasonable purchase costs, and well-proven technology. Condensing boilers adjust their heat output according to the heat demand and the outside temperature, and also make use of the heat in the flue gases which, in other systems, is lost to atmosphere. In so doing, water condenses in the boiler; the integral heat exchange materials are therefore corrosion-resistant. The efficiency of such condensing systems has effectively reached the theoretical maximum – optimal use is made of the fuel.

Convection

The transfer of energy through a moving medium (air, water, combustion gases). This term is very often used in conjunction with radiators. The air in the room moves along the warm surface of the radiator. Heat energy is transferred due to this movement.
