Estimating the expansion coefficient from the difference between the cold system water temperature and the max working temperature.

Expansion tanks come in a variety of sizes. Selecting the appropriate size depends on several factors, such as water pressure, the total water capacity of the system, and the temperature of the water entering and exiting the system. Using these parameters, the recommended standard size is usually determined through charts or software.

Series LFUSG-B Under Sink Guardian Thermostatic Mixing Valves are used in commercial and residential applications to mix hot and cold water in under-the-sink installations to minimize the risk of accidental scalding. It consists of a Lead Free brass body construction with 3/8 in. male compression connections and quick-connect, check valves, tamper resistant locking nut and integral strainer with 40 mesh stainless steel screens to filter out debris. Series LFUSG-B uses a thermostat to control hot and cold water temperature, and dual check valves to protect against cross flow.

The first step is to estimate the expansion coefficient using the table and chart below. The x-axis displays values representing the difference between the cold system water temperature (when the heating is off) and the maximum working temperature. On the other hand, the y-axis displays the corresponding expansion coefficients.
