Hot Water Boiler Short Cycling — Heating Help: The Wall

11/1/2006 · My definition of short cycling is when the BURNER has not run for a long enough period of time that the average efficiency during that burn is noticably less than the steady state efficiency. Other parts of the system can short cycle too, like circs. turning on and off to often but that mostly effects lifetime, not fuel usage.

How To Optimize Your Condensing Boiler System For …

How to optimize your system. In summary, for optimal operation, condensing boiler systems need the return water temperatures well below the dew point of the boiler exhaust (for natural gas, this is around 140°F in the Bay Area and 125°F in Denver), ideally around 80°F or lower. Non-condensing boiler systems require the return water

Boiler Short Cycling - Home Heating And Hot Water …

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 boiler's casing and through the flue.

20/5/2015 · As a result, hot water systems using condensing boilers have lower operating temperatures, 140 to 160 F supply, and 100 to 120 F return. Lower return water temperatures result in more latent heat recovery from the combustion gases and increased boiler efficiency. Condensing boilers are most efficient at lower firing ranges of 20% to 50% (see
