An aquastat is a device which automatically responds to changes in temperature of a liquid.
a reverse acting aquastat closes or activates something on temperature rise
An operating system aquastat senses and controls the temperature of the water in a heating system.

hey any won no the answer.
Aquastats are thermostats sensing the temperature of the water itself, and are used basically to stop and start the burner by controlling the electrical circuit. The temperature of the water is held within preset limits by the aquastats. As the temperature of the water drops to the low setting, the aquastat closes a contact and starts the burner. When the temperature reaches the high setting, the aquastat opens the contact and stops the burner. There is usually a high limit setting which will open the contact, if it should fail to open on the automatic HI/LO control. This feature can be contained within the same instrument or it might be a separate unit. What temperature should the aquastat be set at for the boiler?
Usually on one of the sides with it`s sensing bulb going into a well.
Not plugged in? Gas valve shut? Oil ran out? Thermostat /aquastat not calling for heat?
Bad connection, bad aquastat or bad motor. Or maybe a bad fuse?
Because the aquastat is stuck or shorted.
A wood burner is equipped with a high limit switch and an aquastat to ensure safe and efficient operation. The high limit switch prevents overheating by shutting off the burner if the temperature exceeds a certain threshold, protecting both the system and the surrounding environment. The aquastat monitors the water temperature and regulates the heating process, maintaining optimal performance and energy efficiency while preventing potential damage from excessive heat. Together, these components enhance safety and improve the overall functionality of the wood-burning system.
there may be a problem with the gauge,sensor or thermostat try replacing the thermostat firstI think you mean the AQUASTAT, that controls the fan. The THERMOSTAT is in the upper water hose inlet and controls only the temperature of the water. The aquastat operates the fan, only.
For bldgs with long runs between the source and the use point, a HW recirculating system could be installed. This can be a full loop with a circulator and aquastat, or a check valve between the hot and cold water lines at the farthest fixture with the circulator controlled by an aquastat sensing the return water temp (by Taco Hydronics). Another possibility is an Instantaneous heater close to the point of use; either gas or electric.
