Thank you for the query, Jim. Making a new example for domestic water heating, entering water temperature in North America is around 10 C or 50 F (or colder, below 40F in northern areas such as northern Minnesota). When water is heated it evaporates, which means it turns into water vapor and expands. Consequently, for an S/C ratio of 2.5, CO2 capture from a flue gas stream is competitive with two other locations provided higher weighting factors are considered for the full presence of CO2 in the flue gases stream. Temperature difference is 265 - 15C = 250C. The result can be a dripping temperature/pressure relief valve that can in turn become clogged, rendering the water heating system unsafe, damaging the water heater tank, or even leading to an explosion. The resulting sudden increase in tank pressure can exceed the capacity of the pressure relief valves and perhaps lead to a failure of the roof or wall of the tank.
