2018/8/13 · Condensing boilers produce heat by burning natural gas or propane fuel. The word "condensing" refers to the fact that these appliances are able to extract heat from the combustion process so efficiently that the flue gases leaving the boiler are at a much lower temperature than in a conventional boiler.
In a condensing boiler, heat existing in the flue gasses can be captured and 'recycled' back into the heating system and used to preheat the cold water entering the boiler. During this process, the temperature of the flue gas is rapidly reduced from around 130℃ to 50℃. This fall in temperature causes condensation, from which the name is
chimney is used. The tested boilers show that it is possible to design a proper boiler. The losses, stand-by and convective/radiative, must be kept at a minimum in order to obtain a high efficiency. Keywords Space heating, natural gas, condensing boilers
Gas boilers running on LP Gas (LPG) are a good option if the home is a new, small or well-insulated dwelling and using radiators. Central Heating New Zealand is proud to represent Baxi gas boilers here in New Zealand. A well-known brand in Europe and America, they are also the most popular boiler brand in Australia and New Zealand.
2021/6/10 · Most homeoweners spend $4,500 – 8,000 to install a condensing or a combi boiler. The price for the boiler itself can be as low as $1,485 and can reach $8,750 for a high-end Bosch Buderus SSB model with over 96% efficiency rating. Most condensing boilers fall in the range of $2,500-5,000 depending on the brand, efficiency rating, and capacity.

The decrease in natural gas prices in North America has resulted in  increased retrofitting of existing boiler installations with condensing equipment. Efficiency [ edit ] Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved,  compared to 70%-80% with conventional designs (based on the higher heating value of fuels).
