Although some manufacturers set water heater thermostats at 140ºF, most households usually only require them to be set at 120ºF, which also slows mineral …

Typical operating temperature settings on a boiler call for a Low temperature (boiler cut-in) between 120 and 160 °F. Typical operating temperatures on a hydronic boiler call for a high temperature (boiler cuts off) of 180-200 °F.

Author: David Ludlow Water from the boiler is injected into the radiator circuit at a rate designed to precisely maintain the radiator temperature relative to the outdoors. It can vary from 70 degrees (room temperature) up to 180F if you need it. The boiler is maintained at a different scale, the 180 to 140 range because you have to.

How to Check Your Water Heater TemperatureMost water heaters do not have a temperature gauge with a readout. Instead, the thermostat is marked with temperatures or heating ranges.

Jan 22, 2020· For the condensing boiler to operate at maximum efficiency, the secondary heat exchanger’s surface needs to be equal to or below the dew point temperature of the fuel used. This is the temperature at which water droplets form. For natural gas boilers, the dew point is around 55C.

If the high-limit temperature setting is too high, generally over 200 degrees Fahrenheit, the system pressure will reach an excess condition as well and start leaking. The high-limit temperature setting should be around 190 degrees and the standard hot water operating pressure around 20 psi.

With tank-based heaters, even if no hot water is used the heater still maintains that water at a consistent temperature. Instead, on-demand water heaters heat water on the spot, as needed. The average shower uses between 1-1/4 and 2-1/2 gallons of water per minute; an average on-demand water heater can supply 3-1/2 gallons of hot water per minute.

The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency. Feed water preheating typically occurs in either the feedwater tank or deaerator using supplementary steam.
