Equipment that transfers the heat of combustion to the Heating circuit water. The Heat exchanger is the main component in a Boiler /Heat generator and has a critical effect on Efficiency .
Heat exchanger
Heat generator
Equipment that generates heat and transfers it to the Heating circuit water. It reduces energy losses to a minimum by means of efficient heat exchangers and excellent heat insulation (Condensing boiler ).
Heat of condensation
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 Lower heating value – is about 11 percent for natural gas, 9 percent for LPG, and 7 percent for fuel oil.
Heating boiler
Equipment which transfers the heat of combustion to the Heating circuit water. The latest generation of Weishaupt boilers reduce energy losses to a minimum by means of efficient heat exchangers and excellent heat insulation.
Heating circuit
A system for supplying heat within buildings. It includes the pipework, radiators or underfloor heating, and electronic Circulation pumps (Circulation pumps ).
Heating curve
The Boiler temperature is adjusted relative to the outdoor temperature by means of the heating (or temperature) curve. A low outdoor temperature results in a high Boiler temperature. The setting-up of the Heating curve is very important for efficient heating, and is carefully checked during maintenance.
Higher heating value
The amount of heat released through the complete combustion of a cubic metre of gas (at standard temperature and pressure) or a kilogram of fuel oil, when the water produced by the combustion is liquid. It is measured in kWh/m3 or kWh/kg. It is abbreviated to HHV or GCV (gross calorific value).
