Thermal expansion occurs as coolant accumulates heat from the engine.  The 6% of the expansion volume is calculated from the amount that the coolant level will rise at 212 degrees F. This takes into account the density change of the coolant itself and all the components that are in the coolant system. If the volume is calculated incorrectly and an inadequate expansion space is provided coolant will be discharged from the system at operating temperature.  To prevent the possibility of spilling coolant a catch tank or a recovery tank can be used.

Why would a backflow preventer/check valve be installed in the first place? To prevent your home’s water from backing up into the main supply. Removal of the backflow preventer/check valve may not be an option, as it is likely required by codes in your area. Removal of a pressure reducing valve is also not a likely option, as controlling the water pressure into the home may be necessary.

When water heats in a water heater it expands. The expanding water will typically push back into the supply line preventing excessive pressure from building inside the water heater and often causing a drip or leak from the T&P valve

Expansion tank sizingrule of thumb

The general rule of thumb for proper capacity of expansion is 12% of total coolant volume for draw down and 6% of the total volume for thermal expansion.

When a check valve (backflow preventer) or pressure reducing valve is installed without a built-in bypass water is not allowed to push back into the supply line. Pressure instead builds within the water heater. At 150 psi the T&P will begin releasing water to reduce the pressure within the water heater for your protection.  Should this occur we recommend that you install a properly sized expansion tank. An expansion tank helps by absorbing the excess water pressure in a diaphragm tank. The diaphragm allows for water to flow into the expansion tank as it is being heated and expanding and flow back into the water heater at other times. An expansion tank will prevent wasting water released from the T and P during expansion, as well.

The temperature and pressure relief valve is a safety device that is installed at the factory.  It is designed to open on a residential water heater, for your protection, when there is excessive water temperature or excessive water pressure. There are many things that result in conditions causing a T&P to release water. Thermal Expansion in a closed system is a common cause that is often the last to be considered.

The main job of an expansion tank has to do with, not surprisingly, expansion.  As a basic requirement, expansion tanks should allow enough space for coolant to expand at normal operating temperature and not be pushed out of the pressure relief fitting in the neck.

Lever Type Pressure & Temperature Relief Valve protects against temperature rising beyond 95°C and allows a range of different pressure settings.

When water heats it expands, just as mercury in a thermometer expands rising up the scale to show you a person’s body temperature. If the expansion of the mercury were to exceed the capacity of the thermometer the thermometer would explode. When water heats in a water heater it also expands. The expanding water will typically push back into the supply line preventing excessive pressure from building inside the water heater.

Drawdown capacity is the amount of coolant that can be lost before air reaches the water pump and is introduced into the system. Air bubbles in the coolant system can cause inconsistent cooling and can also prevent the thermostat from opening if an air bubble gets trapped underneath it.

To get the proper expansion tank volume we need to add together the draw down capacity requirement and the thermal expansion requirement to get an additional 18% total volume required for the expansion tank. Most coolant systems are designed to operate with about 13 qts in the system. If we use a 13 qt system as our model. We would use the calculations below:

In a 13 qt System a 2.34 qt expansion tank would be required. In a situation where a large enough tank isn't available a recovery tank can be used in order to take up some of the expansion volume needed. A recovery tank will collect any coolant that is expelled from the pressure relief. In a set up with a recovery tank it is important to make sure that the coolant system is still full enough to allow for drawdown.   For more info on setting up your coolant tank system, see our "Setting up Your Cooling System" blog post.
