Best Hot Water Heating Expansion Tank

The Eastman 60022 2-Gallon Thermal Expansion Tank provides a secure connection to water heaters that prevents dangerous build-ups of pressure. This water heater expansion tank stops hot water from backflowing into the cold water line and it also prevents hot water from escaping through the pressure relief valve and onto the floor. Constant fluctuations in water pressure can be dangerous and they can damage the water heater, properly installing a thermal expansion tank can solve all these issues.

The thermal expansion tank has a high-quality butyl rubber diaphragm and 304 stainless steel fittings for long-lasting performance. This product comes factory pre-charged at 40 psi. It complies with Lead-Free Law.

What is Hydronic Expansion?
Hydronic expansion tanks are diaphragm type tanks designed to keep system pressures below relief valve settings. Hydronic expansion tanks absorb the expansion of water in residential or commercial hydronic (forced hot water) heating and cooling systems. Without hydronic expansion tanks, the system will quickly over-pressurize resulting in added stress to the various system components. Hydronic expansion tanks protect safety valves from failing or wearing out quickly, avoids valve stem and ball seal leaks, prevents wasted BTU’s and vastly extends water heater life.

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.

Everflow female centre tees 3/4 inch Push-to-Connect x 3/4 inch Push-to-Connect x 3/4 inch Female National Pipe Thread (FNPT) center Tee is used to connect copper and CPVC pipes. It is a Lead free DZR brass construction for durability and reliability. The centre tee allows for the fitting to be inserted onto the pipe and then using the disconnect tool slipped back onto the other end of the pipe. This allows for up to a 2 inch section of the pipe to be removed and then repaired without having to add additional pipe. This tee is perfect for removing a section of pipe and adding in an expansion tank for your water heater, the FNPT Tee is threaded so you can screw in the Expansion tank after installing the tee to the line.

Product Description

2 gallon, thermal expansion water heater safety tank, steel outer shell, polypropylene lined water reservoir, heavy duty butyl diaphragm that flexes, leak proof precharged air chamber, reduces pressure build up & harmful pressure spikes, in closed water systems, temporarily absorbs expanded water overflow. This product adds a great value. Product is highly durable and very easy to use. This product is manufactured china.

From the Manufacturer

WaterWorker Water Heater Expansion Safety tanks work on the same principle as pressure tanks. However, the diaphragm flexes up and down due to the pressure from the water expansion from heat in closed loop hot water systems. i.e., in-floor heating systems and hot domestic water systems. When water is heated expansions occurs within the water lines of the house. Excess pressure can damage solenoids, faucet disc and lift the pressure relief valve in the water heater. The Safety Tank absorbs that pressure and extends the life of the water appliances within the house.
