Aquastats: Diagnosis, Repair, Setting & Wiring Heating

I am considering an upgrade to a Smart Thermostat designed for Hot Water Boilers. My boiler is controlled by the L8148E model Aquastat which has a 2-wire control up to an old "not-so-smart" digital thermostat that runs on 2 AA batteries. All of the smart thermostats require a C-wire.

They come in a variety of sizes for different applications, such as a whole-house water heater, a hot water source for a remote bathroom or hot tub, or as a boiler to provide hot water for a home heating system. They can also be used as a booster for dishwashers, washing machines, and a solar or wood-fired domestic hot water system .

These include ovens, hot plates, heating mantles and tapes, oil baths, salt baths, sand baths, air baths, hot-tube furnaces, hot-air guns, and microwave ovens. The use of steam-heated devices rather than electrically heated devices is generally preferred whenever temperatures of 100 °C or less are required.

As you can see, this allows the boiler to heat a tank of potable water, which in turn can provide domestic hot water AND floor heating (in an open or closed configuration). The water from the boiler to this heat exchanger flows 24 hours a day in a closed loop, making the heat exchanger continuously active (i.e. always hot).

Peter Smith, in The Fundamentals of Piping Design, 2007. Gas Tungsten Arc Welding. Gas tungsten arc welding, also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The filler metal is added from an external source, usually as bare metal filler rod. The weld pool area is protected from the atmosphere and

Water Treatment Plant - an overview | ScienceDirect Topics

Treated raw water is mixed with potable water and pumped to the boiler feedwater treatment system. The system is designed to remove 99% of the dissolved minerals and provide high-purity water to the boiler. The mixed water flows through a reverse osmosis plant operating at a recovery of 80% and an average salt rejection of 95%.
