WT8840. The WT8840 series is the Water Heater Control for trade use to replace WV8840 valves used in AOSmith and Bradford White Water Heaters. It is designed for use in Standing Pilot applications using an immersion well for water temperature sensing. An included integrated NTC temperature sensor reads water temperature within the appliance up to 221 F (105 C).
Heating boiler gauges: this article describes the combination pressure & temperature gauge found on most hydronic (hot water) heating systems. The boiler gauge gives helpful temperature or pressure readings that tell us if the boiler is operating normally. The same pressure and temperature readings at a boiler can help diagnose problems such as TP valve leaks, cold radiators, and even boiler
The maximum temperature that we recommend you set your radiator output to is 80 °C. If you have a conventional boiler system, your water cylinder will have its own thermostat. This is usually fitted on the side of the tank. You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C.

Water Heater Repair Tutorial: Temperature Sensors
Low boiler return water temperature depends on the overall boiler system design, not just the boiler. Here is a numerical example of the benefits of a condensing boiler system. A facility using 10,000 therms per year for space heating is estimated to save around 1,489 therms/year and $819/year at $0.55/therm.
9 Water temperature sensor The water temperature sensor monitors the temperature of the water entering the boiler sections. The sensor sends this information to the IBC. The IBC determines how much to adjust the circulator flow rates to provide at least 140°F water to the cast iron heat exchanger. How it works . . . LEGEND a Supply to system
Most aquastats have a sensor that is inserted in an immersion well. The immersion well is located inside the boiler where the water circulates. The sensor senses the temperature. Based on the aquastat setting, this will limit the high temperature in the boiler to prevent overheating. The cutoff temperature for most hot water boilers is 180° F.
The Crown Boiler BWC is available in both natural and LP gas models. The Crown Boiler BWC also includes a microprocessor-based control system. Additional features include direct spark ignition, outdoor reset temperature sensor, domestic hot water priority, pump controls for heating and domestic hot water and a fully modulating burner.
boiler temperature sensor, and ignition control into one for seamless operation. The Intelligent Hydronic Control features an LED read-out, which displays operating information such as boiler status and boiler water temperature. The Intelligent Hydronic Control also displays diagnostic info such as run time hours, the number of heating cycles,
All Peerless Pinnacle gas boilers are equipped with a P825 Control Board that offers state-of-the-art technology, including outdoor reset control with an additional outdoor temperature sensor. The P825 also has built-in technology for domestic hot water priority when an optional indirect tank sensor …
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. Over 200 degrees F. we're at risk of spilling at the pressure temperature relief valve.
The water temperature sensor monitors the temperature of the water entering the boiler sections. Do not add cold water to hot boiler. Thermal shock can cause sections to crack. Natural gas boilers — gas line sizing (for 0.3" w.c. drop). Propane boilers — refer to gas supplier. 38 – 39
