  • SuperStor 45 Gal. Indirect Water Heater-SSU-45 - The Home Depot

    An indirect fired hot water heater is essentially a storage tank with an internal coil. Boiler water is pumped through the coil to heat the potable water in the tank. Put differently it is a heat exchanger with some hot water storage. The thinking is that the stored hot water will supply the user while the boiler is coming up to temp.

    An aquastat is a device used in hydronic heating systems for controlling water temperature. To prevent the boiler from firing too often, aquastats have a high limit temperature and a low limit. If the thermostat is calling for heat, the boiler will fire until the high limit is reached, then shut off (even if the thermostat is still calling for

    Modern boiler systems for home heating are hydronic systems, in which the boiler heats water for circulation throughout the house.They are closely related to steam boiler systems, but rather than circulating actual steam, hydronic systems have pipes carrying the hot water that radiates heat through either steel radiators or baseboard convectors (sometimes called "fin-tubes").

  • How Does the Aquastat on a Boiler Work? | Hunker

    The aquastat on a hot water boiler is essentially a combination heating control. The aquastat monitors the water temperature in the boiler through the use of a copper bulb that stays in contact with the water inside the boiler and that shuts down the boiler automatically if the low- or high-temperature set point is exceeded. Understanding how the controller works can help users who are uncertain of why their boiler is shutting down unexpectedly. One of the features of a hot water boiler aquastat is the low-limit setting, which is either pre-set at the factory or adjusted by the homeowner on the controller. Once the water temperature reaches below the low-limit setting, the boiler burner turns on and begins to heat the water to maintain the desired water temperature. The other primary control on the aquastat is the high limit, which is the highest allowable hot water temperature before the controller shuts down the boiler. This is also factory pre-set or adjusted by the homeowner. The boiler burner automatically shuts off when the high-limit temperature is reached. The burner will restart when the water temperature falls within a differential temperature, usually about 10 degrees Fahrenheit, below the high-limit setting. This maintains a general set temperature for the water inside the boiler.
