The circulator circulates the heat transfer fluid to the heated zone. As with the Dual Acting Boiler Temperature Control, the circulator turns on and off by thermostat input. The boiler temperature control opens to turn the circulator off if boiler water temperature drops below the low limit to maintain a minimum boiler temperature.
At the setting shown, if LO were set to 120, when the burner is re-heating the boiler water and water temperature rises to 130 F the burner will turn off and the heating circulator pumps will be allowed to turn on (and they will actually turn on if the room thermostat is calling for heat).
Low temperature oil boiler The versatility of the Vitoplex range, which is technically and in terms of price categorised into stages 300 and 200, ensures that the perfect solution is available for every demand and any budget.
Boiler temperature. Selecting a lower temperature will also mean the burner changes to the lower gas flow rate sooner, the lower flow rate being more efficient than the high flow rate. Lower water temperature also reduces temperature yo-yoing due to having very hot water in the radiators when the thermostat switches the boiler off.
Fire-tube boilers usually have a comparatively low rate of steam production, but high steam storage capacity. Fire-tube boilers mostly burn solid fuels, but are readily adaptable to those of the liquid or gas variety. Fire-tube boilers may also be referred to as "scotch-marine" or "marine" type boilers.

Some low NOx controls reduce emissions by lowering flame temperature, particularly in boilers with inputs less than 100 MMBtu/hr. Reducing the flame temperature decreases the radiant heat transfer from the flame and could lower boiler efficiency.
This provides the appropriate level needed for most cold weather temperatures. If you can raise the temperature manually, do not set it any higher than 210°F (which is often the limit), and try to remain down at 190°F if you need the extra heat. Once a boiler starts to go over 212°F, you can face serious problems. Watch out for overheating
But boilers don't usually need to work to 100% of performance, they usually range between 30 and 40%.
