30 degrees in 6 minutes that equals 36 gallons of hot water. This is normal for a 50 gallon water heater. The amount will be about 70% of the capacity of the heater. Results: If the test performed above results in a 70% (+ /- 10 %) capacity, then the heater is performing per specifications and a larger water heater should be considered in
pieces of equipment in the system and the total volume of the system. That is, for closed hot water heating systems that are heated by a hot water boiler, the estimated total volume of the system is determined by multiplying the boiler horsepower by 10. For example, for a 50 hp boiler, the estimated total system volume would be 50 X 10 = 500 USG.
Hot water heaters can provide water as high as 140 degrees. Doctors recommend setting your heater at 120 or below to avoid dry skin. You risk damaging the skin’s lipid layer if your water above 112 degrees.

If you use a 611 watts heater in this example, then it will be about enough to reverse this cool-down from 105f to 103f by heating the water back up from 103f to 105f during the same period (realistically, of course, the water does not cool down, but stays at the same temperature).
A simple formula to estimate the energy required to heat a volume of water is : E = C*V*DeltaT*PR. Where E = energy in kWh. C = Specific heat of water - 4.187 kJ/kgK, or 1,163 Wh/kg°C. V = volume of water to heat. deltaT = Th-Tc. Th = temperature of hot water. Tc = temperature of input cold water.
the specific volume of water from 60 °F (ambient temperature) to the maximum operating temperature of the boiler and related system. To design the expansion tank, you must first know the total volume of water in the flooded boiler and system. For flooded values for a Cleaver-Brooks boiler, refer to the boiler products section.
