THERM-X-TROL® Expansion Tanks
What Is Thermal Expansion?
With modern plumbing codes mandating backflow prevention,
thermal expansion can cause pressure buildup in domestic water
systems. When demand is put upon a potable water system,
hot water is drawn from the water heater. Cold water from the
supply line enters the water heater
to replenish it. The cold water is
heated to replace the hot water
used. With the installation of a
backflow preventer, check valve
or pressure reducing valve on the
supply line, the water heater and
the system piping form a closed
plumbing system under pressure.
As the water is heated, thermal
expansion occurs. Pressure increases until the relief valve opens
and the expanded water spills from the water heater. This spillage
results in wasted energy and a potential safety hazard. (See
Diagram 1)
Closed Potable Hot Water System
without THERM-X-TROL®
Backflow preventer, pressure reducing valve or other one-way device
causes expanded (heated) water to build pressure causing the relief valve to
open resulting in…
• Wasted energy
• Shortened water heater life
• Wasted municipal water and sewer dollars
• Potential safety hazard
The THERM-X-TROL® is designed to eliminate this problem by providing
control of maximum pressures at a level below the relief valve setting. It also
provides an additional space in the system to accommodate the increased
volume of water created by thermal expansion, returning it to the system
when hot water delivery is demanded. Maximum pressure is kept well
below the relief valve setting by the THERM-X-TROL®, with its pre-charged
air cushion that is separated from system water. The relief valve does not
open, therefore spillage is eliminated (Diagram 2).

with THERM-X-TROL®
Expanded (heated) water is absorbed by THERM-X-TROL® which means…
• Water heater and fixtures are protected
• Eliminates energy and water waste, saving money
• No dangerous pressure build up in the system
• Relief valves will not open
• Potential safety hazard reduced

Precise Sizing Procedure - For Special Applications
The procedure for sizing the Therm-X-Trol® for
any application depends on four (4) vital pieces of
information:
1. ASME or non-ASME requirement
2 Calculated thermally expanded water volume
3. Minimum water pressure experienced at the tank
location
4. Maximum water pressure allowable at the tank
location
The tank required for any application can be sized with
the following equation:
Tv = Design Pressure Factor X expanded water
Where Tv is the total Thermal-X-Trol® volume required
in gallons.
Example: A 240 gallon water heater with a 150°F aquastat
setting is installed with a 125 psi maximum pressure
requirement. For a static supply line pressure of 60
psi, what Therm-X-Trol® model is required for critical
protection?
Critical Sizing AMTROL® Therm-X-Trol®
1. Total Water Heater Volume (Gallons)
2. Water Expansion Factor (Table I)
3. Calculate Expanded Water (Gallons)
(Line 1 x Line 2)
4. Design Pressure Factor (Table II)
5. Therm-X-Trol Volume Required (Gallons)
(Line 3 x Line 4)
6. Select Therm-X-Trol® Model (pg. 6 & 7)
Critical Sizing AMTROL® Therm-X-Trol®: EXAMPLE
1. Total Water Heater Volume (Gallons) 240
2. Water Expansion Factor (Table I) 0.0179
3. Calculate Expanded Water (Gallons) 4.3
(Line 1 x Line 2) = (240 x .0179)
4. Design Pressure Factor (Table II) 2.1
5. Therm-X-Trol Volume Required (Gallons) 9.0
(Line 3 x Line 4) = (4.3 x 2.1)
6. Select Therm-X-Trol® Model (pg. 6 & 7) ST-25V
ST30V-C
Note: The Therm-X-Trol® air pressure should be equal to static line pressure.
