Glossary. Heating technology
explained simply.

All about heating. From A to Z.

When it comes to heating, there are a few technical terms that need to be explained. You can find everything you need to know here. In alphabetical order.

Carbon dioxide

A gas produced when materials containing carbon are combusted. The injection of Carbon dioxide  into the earth's atmosphere results in climate change, global warming, sometimes also referred to as the Greenhouse effect . Reducing fuel consumption reduces Carbon dioxide  Emissions .

Carbon monoxide

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

Circulation pumps

An electronic water pump, which pumps the Heating circuit  water to radiators or underfloor heating. Electronic Circulation pumps  are prescribed.

CO

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

CO2

A gas produced when materials containing carbon are combusted. The injection of Carbon dioxide  into the earth's atmosphere results in climate change, global warming, sometimes also referred to as the Greenhouse effect . Reducing fuel consumption reduces Carbon dioxide  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 cubic metres of Combustion air  is required for the complete combustion of 1 cubic metre of gas or 1 litre of heating oil.

Combustion gases

Products resulting from the combustion of fuel and air. In the main, Carbon dioxide  (CO <sub>2</sub>) 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 enables 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 achieve the temperature level required for heating purposes.

Condensate

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

Condenser

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

Condensing boiler

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.
