An electric boiler can be placed in operation quickly, as there is no furnace to reach high temperatures. [4] Environmental impact is displaced to the source of the grid electricity; however, if fossil fuel is being consumed to make electricity, overall efficiency will be lower than direct use of the fuel.
High efficiency condensing gas furnaces typically achieve between 90% and 98% AFUE. [3] A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as compared to a mid-efficiency forced-air or forced-draft furnace, is the ...
Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value ) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.
A district heating system uses centrally located boilers or water heaters and circulates heat energy to individual customers by circulating hot water or steam. This has the advantage of a central highly efficient energy converter that can use the best available pollution controls, and that is professionally operated.
Babcock-Johnson boiler: early production Johnson boilers operating at high pressures (850 psi [59 bar; 5,900 kPa]) and with water-wall ends to their furnace. [4] Babcock & Wilcox boiler; Babcock & Wilcox marine boiler; Bagnall boiler: a development of the launch boiler, with an enlarged furnace. Also known in agricultural use as the 'colonial ...
