What should my aquastat be set at?
Recommended High-Limit Setting In most cases, the high-limit temperature setting on an aquastat should be between 180 and 200 degrees Fahrenheit. If the aquastat is set at 200 degrees Fahrenheit as the high-limit setting and the pressure valve begins to leak, set the temperature back to 195 degrees Fahrenheit.
How does an aquastat controller work?
The bulb is inserted in the water. As the fill in the bulb is heated by the water, it expands through the tube and exerts pressure on the switch. Pressure changes cause the switch to open or close, which turns the boiler off or on.
What is the best temperature to set your boiler at?
As a rule, setting your heating control to 75 degrees should be sufficient to give you a perfectly warm house, while also allowing your boiler to run as economically as possible. Once this is set, you shouldn’t need to adjust it.
What is the purpose of aquastat?
The aquastat is a device that controls the temperature of the water inside the boiler – much as a thermostat does for the air inside the house.
Why is my boiler not reaching set temperature?
If your unit isn’t calibrated correctly, this could lead to a thermostat not reaching set temperature. Luckily, a simple recalibration should do the trick. This problem typically occurs with newer thermostats or systems that just experienced a power outage. Older thermostats may also need a recalibration over time.
What temperature should a hot water boiler run at?
The best temperature for your hot water cylinder is between 140-150 degrees Fahrenheit. For health and safety reasons, try to keep your boiler water temperature from getting too low. A bacteria called Legionella can grow in freshwater with a temperature of 77-112 degrees Fahrenheit.
How do you test a boiler control?
To test the high-limit control, disconnect the power to the boiler controls and place a test lead across the terminals of the operating control. Check the setting of the high-limit control. Restore power to the controls and fire the boiler.
How do I reset my Honeywell Aquastat?
Unlike the aquastat shown at the top of this page, poking through the upper-center of the cover of this heating system control you’ll see a red ” reset button ” in the center of the upper portion of the gray control box.
