Efficient heat generation - Modern condensing boiler technology, running on natural gas, contributes to savings of energy and costs for the supply of heating in the home. Natural gas-fired condensing boilers work very efficiently because they also use the energy contained in the combustion exhaust gases. Anyone opting for natural gas condensing technology is choosing a particularly environmentally-friendly and convenient form of heat generation. Modern condensing boilers are capable of generating the necessary heat for central heating and for domestic hot water in an ecologically sound and resource-friendly way. Because of these advantages, condensing boilers run on natural gas are often the first choice both for new installations and for the refurbishment of existing central heating systems. Europe in 2008, some 310,000 natural gas-fired condensing boilers were sold.
Condensing boilers cover almost all output ranges. Wall-mounted units deliver up to 100 kW. Connected one to the other in a cascade system, the output can be increased to several hundred kilowatts. Floor-standing units can supply nominal outputs of more than 10,000 kW.
Well-established technology: after more than twenty years gas condensing boilers are now technically very sophisticated. This applies in terms both of their convenience and their noise levels. Moreover, their modern design means that appliances fit unobtrusively into their surroundings. Given their very low-noise and odourless operation these units can be installed without difficulty in almost all areas of a building. They need little space and fuel does not need to be stored near them. Moreover, even very erratic output requirements for heating and hot water can be efficiently met.
