Boiler efficiency cycling vs continuous run — Heating Help

Mar 15, 2013 · To minimize parasitic losses -- heat lost from the steam mains, lost by radiation from the boiler, etc. -- you'd like to do that in as short a time as possible. However, the radiation can only deliver heat at a certain maximum rate -- so there is a minimum time which the radiation must be at steam temperature to do the job.

System Conditions that Affect Boiler Efficiency

There is an old rule-of-thumb that states: A short-cycling boiler will operate at least 15% points below its rated efficiency when said boiler is not short-cycling. The loss of fuel efficiency can be staggering, which means the wasted fuel consumption is paid for by the unsuspecting homeowner with …

Retrocommissioning Findings: Reducing Boiler Purge Cycle

Mar 24, 2016 · Capped the short cycle rate at 7.1 per hour; this was an arbitrary reduction of the maximum observed cycling rate, meaning I was sure that during hot weather there would be at least this many short cycles in an hour. The data we gathered indicates there could be twice as many if both boilers fired the way the East boiler fires when it short cycles.

Boiler Short Cycling - Home Heating Systems and Solutions

Boiler Short Cycling Short Cycling. Boiler short cycling occurs when a boiler subject to its own internal thermostat 'fires up' - starts operating when the thermostat detects that the water in the boiler has cooled down.. For example: When your heating system does not require the boiler to fire, the heated water in the boiler's heat exchanger will begin to loose heat to the air around the
