Most contractors recommend some variety of high efficiency condensing gas boiler. One contractor, however, said that high efficiency condensing boilers lose much of that high efficiency because the house has an older baseboard heating system designed for 180 degree water.
The Peerless® PUREFIRE® Series gas-fired condensing boiler from PB Heat, LLC is a high-efficiency 95% AFUE boiler for residential applications and is available for either natural or LP gas systems. The direct vent, sealed combustion boiler features a fully modulating, stainless steel burner and is environmentally friendly with LoNox operation.
Mini economy intelligent wall hung gas boiler ECO Heat exchanger fins increase disturbance flow structure, reduce heat transfer blind area, heat exchanger patent design (ZL 2016201481128.9), heat efficiency up to 92%; ultra low nitrogen oxide design, green environmental protection.
Condensing extracts that latent energy from the combustion exhaust gas and heats the water with it, increasing overall boiler efficiency. High efficiency boilers require combustion gas calibration at start up.
A low temperature, three pass oil/gas boiler with a heating output of 90 - 1950 kW. The Vitoplex 200 burns cleanly in an environmentally responsible manner, with particularly low nitrogen oxide emissions.
Condensing Boilers Can Ensure a 90% Efficiency Rate. Not only is the condensing boiler a good option if you are concerned about your carbon footprint but condensing boiler manufacturers also claim that the efficiency rate of their products can reach up to 98%.
Steam boiler is used for heating, gelatinization, and saccharify, etc. Heating equipment is equipped under mash kettle, and then steam produced by High efficiency low nitrogen gas steam boiler enter into the heating equipment, and then heat the raw materials for starch hydrolysis.
