Boiler System Energy Losses - NRCan

Radiation and convection losses are independent of the fuel being fired in a boiler and represent heat lost to the surroundings from the warm surfaces of a boiler or high-temperature water generator. These losses depend mainly on the size of the equipment (e.g.‚ small boilers have a proportionately larger percentage loss than large boilers)‚ and the actual output relative to the maximum

Boiler Supply and Return Piping HVAC Quality Tips 101

Boiler Supply and Return Piping - Any heating pipe system will experience a heat loss in the pipe even when the pipe is insulated. The loss is far greater when the pipe is uninsulated. Good boiler piping insulation will reduce the heat loss experienced in the pipe run throughout the loop especially where the pipe runs in unconditioned or unheated spaces where heating is not necessary.
