The Boiler Efficiency Calculator takes into account only major energy losses‚ which typically represent 10 to 20% of fuel input. The major energy losses fall into two categories: stack losses‚ and radiation and convection losses. This section deals with the second type of losses‚ that is the heat lost to the surroundings from the warm surfaces of a boiler or high-temperature water generator.

Expressed as a percentage of the boiler's heat output, the loss increases as boiler output is reduced. Hence, operating the boiler at full load lowers the percentage of loss. Since the boiler's surface area relates to its bulk, the relative loss is lower for a larger boiler and higher for a smaller boiler.
generally ignored. Credit for solar heat gain is a plus factor in winter heating. HEAT LOSS FROM BUILDING ENVELOPE (Wall, Roof, Glass) Heat loss occurs from a building structure primarily due to conduction. Because heat moves in all directions, when calculating the heat loss of a building, we much consider all surfaces
Pressure losses The pressure losses in the heat exchanger units of the boiler are estimated according to the following approximations: • Economizer: the pressure loss is 5-10 % of the pressure of the feedwater entering the economizer. • Evaporator: Once through boilers: in once-through boilers the pressure loss of the evaporator is

The extreme example would be a boiler sized to the heat loss heating a single massively oversized radiator. If the rad was oversized substantially it wouldn't matter since it would still condense all the steam (and release the BTU's to the space). As you add more rads it becomes more sensitive to distribution anomalies.

Boiler Link is a more flexible and powerful boiler control system than any other product on the market. It can connect any boiler, burner, instrumentation or other device in your boiler room, creating a more integrated, efficient system.
I figured I'd have a go at calculating the standby heat loss of my boiler. I'd appreciate if you guys could take a look and see if I've missed anything or done anything silly: First I shut off the boiler and circulation pumps so I'm only measuring the heat loss from the boiler at idle. Note that the boiler drops from 187F to 154F over two hours.
