May 28, 2013 · What is the Most Efficient Temperature to Keep the Boiler At? Posted on May 28, 2013 With fuel bills representing a considerable proportion of the average household’s expenditure, it is not surprising that many of us want to know the most energy saving and cost-efficient method of running a boiler.
Mar 21, 2001 · If the minimum inlet temperature to the boiler or water heater is maintained above the minimum dewpoint temperature, condensate is controllable. It is virtually impossible to cool the flue products to dewpoint when the minimum inlet water temperatures are maintained above the dewpoint temperature based on this data.
The gas efficiency is defined as the ratio of the temperature drop. Corrected leakage to the temperature head, expressed as a percentage. Temperature drop is obtained y subtracting the corrected gas outlet temperature from the gas inlet temperature. Temperature head is obtained y subtracting air inlet temperature from the gas inlet temperature.
