  • Thermal Expansion tank purposeWater Heaters Installed

    Thermal expansion is the number one reason that water heaters fail prematurely. In some cases the expansion tank can also fail which usually means the water heater is next. When an expansion tank fails it becomes water logged. It s a good idea to check the pressure inside of your expansion tank to ensure it s working properly.

    A greater volume of ocean water due to thermal expansion casuses a rise in sea level. Second rising temperatures are causing ice and snow on land to melt thereby increasing the amount of water in the oceans. (Only melting of ice and snow that are on land will increase sea level. The melting of floating ice will not affect sea level.)

  • Thermal Expansion and Density EARTH 111 Water Science

    Thermal Expansion and Density. When water is a liquid the water molecules are packed relatively close together but can slide past each other and move around freely (as stated earlier that makes it a liquid). Pure water has a density of 1.000 g/cm3 at 4˚ C. As the temperature increases or decreases from 4˚ C the density of water decreases.

    A dripping Temperature and Pressure Relief (T P) Valve on the water heater is an indicator of a potential thermal expansion problem. This is the valve with the small handle or lever that automatically opens when either the temperature or pressure inside the heater tank exceed a set limit (usually 150psi/210°F).

    Thermal Expansion of Water. Most solids and liquids expand with rising temperature. Water the most common and most important liquid on Earth has a limitation on this expansion. Ice water that is at a temperature of 0oC or 32oF will contract when it is heated. This contraction continues until after an increase beyond 4oC or 39.2oF.
