Feature
Warranty: 5 year limitedTank: 16 gauge cold rolled steel
Finish: Appliance quality paint for indoor or outdoor installation
Water chamber: 100% butyl rubber, lined with polypropylene
Connection: Stainless Steel
Description
Falcon Stainless E.T. potable water expansion tanks are designed to maintain safe pressure in domestic water systems that utilize a back flow preventer or check valve. E.T tanks feature a 100% butyl diaphragm and plastic liner to separate the system water from the tanks air precharge. The system connection has a stainless steel sleeve to prevent corrosion making it even more reliable. And, the tanks are finished with appliance quality paint which helps prevent external corrosion. On top of all this every E.T. tank is comprehensively tested and backed by Falcon's 5 year limited warranty. If this doesn't relieve all of the pressures that cause you to worry, nothing will.2. Eastman 60022 Expansion Tank, 2 gallon
Feature
2 gallon tank3/4 inch mip connection
Factory pre-charged at 40 psi
304 stainless Steel fittings
Butyle rubber diaphragm
Description
This thermal expansion tank prevents hot water from back flowing into the cold water line. This tank also prevents hot water from escaping through the pressure relief valve and onto the floor. The thermal expansion tank prevents constant fluctuations in water pressure that damage the heater.3. AMTROL ST-5 Thermal Expansion Tank
Feature
Accepts expanded water caused by thermal expansionReturns water to the system when hot water is used
Prevents the relief valve from going off
Inline thermal expansion tank
Prevents dripping faucets, intermittent toilet fill and pressure relief valve discharge
Protects water heater, appliances and fixtures
Description
Amtrak invented the thermal expansion tank to control pressure build-up in closed, hot water systems. This prevents the water heater pressure relief valve from opening, saves energy and eliminates a potential safety hazard. All thermo-x-troll expansion tank.4. AMTROL 102-1 #30 EX-30 30 Extrol Expansion Tank
Feature
InLine well tankWatertight reservoir for expanded water
Thick, heavy duty Butyl/EPDM diaphragm for long service life
Sealed air cushion - factory pre-charged and 100% tested
Strong, deep-drawn steel tank
Description
Amtrol Inc. designed and patented the first Extrol diaphragm expansion tank in 1954 to control system pressure and help reduce energy consumption in heating and chilled water systems. Over six decades later, Extrol is still the world's leading expansion5. Watts ETX-15 2.1-Gallon Non-Potable Expansion Tank for Hydronic Heating Systems
Feature
For use in closed-loop, non-potable water heating systems^2.1-Gallon capacity^Durable steel tank^60 psi maximum working pressureDescription
Use the Watts series ET water expansion tank in tandem with your hot water heater to absorb increased water volume resulting from hot water boiler heating and keep system pressure below the relief setting. Use in closed-loop, non potable water heating systems. Durable steel tank with 60 psi maximum working pressure.6. Amtrol ST-12 Thermal Expansion Tank
Feature
Eliminates the waste of energy and water, thus saving moneyPrevents a dangerous pressure build-up in the system
Prevents the relief valve from going off
Description
Amtrol ST-12 THERM-X-TROL Expansion Tank, 4.4 Gallon (141N43) 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 colder 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 BTU's and a potential safety hazard for the homeowner. Closed Potable Hot Water system without THERM-X-TROL Backflow preventer, pressure reducing valve or meter causes expanded (heated) water to build pressure causing the relief valve to open resulting in: Wasted BTU's Shortened water heater life Wasted municipal water and sewer dollars Potential safety hazard for homeowner The Amtrol THERM-X-TROL ST-12 Expansion Tank 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.7.
