FGR means that the exhaust gas is recycled proportionately back into the furnace to reuse and lower the flame temperature as well as to improve efficiency. It is designed for customers who are in large demand for Heating supply.
Condensing Gas Boilers. Condensing gas boilers function at extremely high efficiency levels because of their design. Condensing boilers are designed to preheat water from the mains cold water tap before it is heated by the boiler’s burner. The water is already warm so takes much less time to heat, saving on both energy and heating costs.
Nov 16, 2017 · · Condensing Gas Boilers. A condensing gas boiler is usually not a different type of boiler all by itself. The term is used when describing the functions of the boiler in question. Due to energy saving regulations and awareness of reducing carbon footprints, most modern boilers will feature condensing in their systems.
gas-fired, high efficiency, non-condensing boiier rated at 230 kW. Domestic hot water is provided by two separate gas-fired storage water heaters rated at 105 kW each.

Typically a condensing gas boiler would have seasonal efficiency of 88% compared with a non-condensing boiler at 75% and some older type boilers at 55-60%. When in condensing mode (for condensing boilers do not condense all the time) the flue gases give up their 'latent heat' which is then recovered by the heat exchanger within the boiler. As a result the temperature of the gases exiting the
The condensing waste heat recovery boiler reduces the exhaust gas temperature to 50~70℃, and fully recovers the sensible heat and condensation latent heat of water vapor in the flue gas, improves the thermal efficiency.

Dec 17, 2018 · The extent to which the condensing boiler can fully utilise the thermal energy resulting from condensation depends primarily on the given temperature of the heating system. The lower the temperature of the water entering the condenser, the more efficient the gas cooling process will be.
Non-condensing boilers typically have efficiency ratings that range from 80% to 88%, while those of condensing boilers are usually above 88%. To qualify for an ENERGY STAR® certification from the Environmental Protection Agency and U.S. Department of Energy, oil-fired boilers must exceed 87% AFUE and gas-fired boilers must exceed 90% AFUE.
This heat exchanger cools flue gases before they escape up the chimney. This process releases extra heat, which is transferred into the heating system. Thanks to this condensing technology, our gas condensing boilers are rated energy efficiency class A and they achieve efficiency of up to 98 per cent.
Boilers. Gas-fired condensing boilers not only use supplied energy, in comparison to older boilers they also utilise thermal energy contained in the flue gas, energy which is
