Common Terms, What Happens When Water Is Heated

COMMON TERMS

Draw efficiency is the quantity of hot water available to the consumer before the outlet water temperature decreases 25°F. A 40-gallon water heater will typically provide 70% (28 gallons) within this temperature range. The burner or elements are allowed to operate during this test. Incoming, cold water mixes the remaining stored water below this 25° limitation.

Energy factor is an indicator of the combined thermal efficiency and standby efficiency of a water heater. The higher the energy factor, the more efficient the water heater will be.

What Happens

When Water Is Heated:

1The relationship between water temperature and time to burn normal adult skin.

WATER	TIME FOR 1ST	TIME FOR PERMANENT BURNS
TEMP. °F	DEGREE BURN	(2nd AND 3rd DEGREE)
105	Normal shower temperature
122	1 minute	5 minutes
131	5 seconds	25 seconds
140	2 seconds	5 seconds

2Water cannot (for all practical purposes) be compressed.

3Water expands when it is heated. Approximately .00023% per degree F temperature rise.

This expansion will result in a pressure increase in a “closed” system. Water confined to a storage tank or piping system will, when subjected to a temperature rise of 10°F (increasing from 75°F to 85°F) increase in pressure from 50 psi to 250 psi.
