Thermal Expansion

WHAT IS THERMAL EXPANSION?

When water is heated it expands. For example, water heated from 90°F to a thermostat setting of 140°F in a 40 gallon hot water heater will expand by almost one-half gallon. This is because when water is heated, its density decreases and its volume expands (see below). Since water is not compressible, the extra volume created by expansion must go someplace. During no-flow periods in a system, pressure reducing valves, backflow preventers, and other one-way valves are closed, thus eliminating a path for expanded water to flow back to the system supply. Hence, system pressure increases.

TEMPERATURE VS DENSITY

Thermal expansion of water in a closed plumbing system can create a number of annoying and potentially dangerous problems. These include: the buildup of unusually high pressure in a system (even when a pressure reducing valve is installed); pressure surges; and the chronic or continuous dripping of a temperature and pressure (T&P) relief valve. In addition, dripping faucets and leaking toilet tank ball cock fill valves are also symptomatic of thermal expansion. More serious problems can also occur due to thermal expansion. When dangerous pressures are built up in a water heater, internal parts may fail such as the internal flues, fittings or water connections. If a flue way collapses it can lead to the potential release of toxic gases, such as carbon monoxide into living spaces. Thermal expansion can also lead to a ruptured or distorted hot water heating tank and may void the manufacturer’s warranty.

 

EXPANSION TANK

By installing an expansion tank you are giving the expanded water a place to go, without damaging any of your existing plumbing.  We recommend that everyone has one expansion tank for each hot water tank in your house.  Any one of our qualified techs can properly install one to your existing hot water tank.  Just call the office anytime – 770-735-3855
