The boiler features a built in boiler pump and a low water pressure sensor, and includes a Labor Saving Primary/Secondary manifold. There are optional manual-reset safety device kits available for high temperature limit and LWCO. Venting can be Coaxial, 2-pipe, or 1-pipe.
The basic cost of heating fuel per BTU is not enough data to determine the most cost efficient way to heat a home because even with a lower-cost fuel in hand, if the efficiency of the heating equipment is low you may be sending a high portion, up to 50%, of your heating fuel dollars up the chimney instead of into the building.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
The percentage of the heat energy contained in the fuel that is captured by the working fluid (e.g. water) in the boiler is defined as the combustion efficiency of the boiler. Combustion efficiencies of 80% or higher are usually possible for hot water boilers and low pressure steam boilers for commercial buildings.
It is suggested to use oil, gas, solid biomass fuel, and electric as the boiler fuel when generate steam, as the advantages of low pollution, low cost, and clean.
