The Heat Balance and Efficiency of Steam Boilers

Moisture free fuel should be fed to the boiler so that no amount of heat is lost in removing the moisture from fuel and all the heat can be efficiently used to convert water to steam. Most heat losses are due to the high temperature of dry flue gases leaving the boiler. Boiler maintenance should be done regularly and be removing the scale deposited on the heat transfer tubes should be given prime importance as this scale prevents the transfer of heat …

Electric Boilers - eComfort

Feb 10, 2013 · Building heat loss plus system losses should equal boiler output at design conditions. The efficiency of a mod/con boiler drops a bit with higher return water temperatures, so there is some interaction with system design here. Assuming the heat loss is accurate, I'd probably look at a Triangle Tube PTS60 or a Lochinvar WHN055 for that heating load.
