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. | ![]() B001B1JHHO Price: $66.39 Score: 9.709 Category: Tools Rating: 4.6 Votes: 459 Find similar productsAMTROL ST-5 Thermal Expansion Tank.

Product Description This 2. 1 gallon non-potable water expansion tank is for use in commercial and residential closed loop hydronic heating system piping to control the thermal expansion of hot water and maintain system pressure below the relief setting of the relief valve. The pre-pressurized steel tank features a durable expansion membrane that prevents contact of the water with the air in the tank. This rugged diaphragm minimizes loss of the air change and ensures long and trouble-free life for the system. Maximum pressure is 60 psi (4. 1 bar). From the Manufacturer 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. | ![]() B00JWSYVLA Price: $148 Score: 6.757 Category: Tools Rating: 4.3 Votes: 12 Find similar productsHydrolevel 1100 Safgard Low Water Cut-off for Gas Hot Water Boilers 24V.

This compact , yet powerful unit - with gas inputs up to 170,000 BTU per hour - can meet all the hot-water needs of a small to medium American home or apartment. This CSA approved heater is designed to virtually do anything a 40-gallon tank-type water heater can do and much more The Wall mounted 24 LITER/MIN Excel Pro is design to work with hydronic baseboard or radiant floor heating applications, as well as provide domestic hot water to plumbing fixtures and appliances. LCD Display Control: Just set the desired water temperature The Excel Pro has an energy factor of 0.84-0.85. Excel Pro: Modulating Technology Tankless water heaters can be further divided into two categories according to their heating capability: full on/full off versus modulating. Full on/full off units do not have a variable power output level; the unit is either fully on or completely off. This can cause an annoying and possibly hazardous variation of hot water temperature, as the flow of water through the heater varies. Modulated tankless water heaters change their heat output in response to the flow rate of water running through the unit. The Excel Pro comes with a display panel where you can set the output temperature and regardless of water flow the unit modulates the fire power.

Stiebel Eltron 235089 Model SHC 6 Mini-Tank Electric Water Heater, 120 Volts, 1300 Watts, 11.3A, 6.0 Gallon, 1300W, Singe Phase, 45 Minutes Recovery Time, 150 psi/10 bar Maximum Operating Pressure An SHC mini-tank frees up precious space while providing plenty of hot water for hand washing or kitchen applications. Why store 30 or more gallons of hot water when 6, 4, or even 2.5 gallons are sufficient? With its flat back and included bracket an SHC easily mounts right under or near the sink. Once filled with water it simply plugs into a 120 V outlet. With only an 11 amp current draw, no special wiring is required. Lightweight and compact, the SHC saves space, quickly provides hot water right where it is needed. Plumbed with cold water and used as a stand-alone supply of hot water, or plumbed with hot water from a remote tank to minimize delays, an SHC always delivers hot water when needed. By putting hot water right where it is used, pipe runs are minimized and water and energy use reduced. The smaller tank coupled with superb insulation reduces stand-by losses especially when compared with larger tank-type water heaters.
