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.

Tank Max – water heater protects your family from scalding by allowing water to be 140 degrees (F) in the water heater while distributing 120 degree (F) water to fixtures. Lead-free and easy to install, tank Max saves money by extending the life of the hot water in your water heater. No solder or glue needed. Installation requires only a wrench and pipe thread sealing tape. Product specifications PDF below.

What is Thermal Expansion?
When heated, water expands. Under normal circumstances, a 40 Gallons hot water heater creates roughly an additional half gallon of water when heated (with no demand). In the past this expanded water would flow back into the public water supply. However, in many countries, where applicable by code, a backflow preventer is required, creating a closed system and a new problem as this extra half gallon of water is not compressible. When an expansion tank is installed the excess water enters the pre-pressurized tank. As the temperature and pressure reaches its maximum, the diaphragm flexes against an air cushion (air is compressible) to allow for increased water expansion. When the system is opened again or the water cools, the water leaves the tank and returns to the system.

Potential Problems Without an Expansion Tank

• Premature failure of the water heater may void the warranty of the water heater
• Dangerous high pressure
• leaky fittings and valves
• collapsed center flues
• flames out of combustion chamber
• Unnecessary Relief Valve Discharge

Installation Options for Thermal Expansion Tanks

• Install on the cold water side after the pressure reducing valve and between the backflow preventer and the water heater
• Do not install in an area where leakage could cause property damage
• The tank can be installed either vertically or horizontally. However, if the tank is to be installed horizontally, then it must be fully supported independent from the piping. Failure to do so will void the warranty.

Utilitech 2-Gallon Expansion Pressure TankItem #: 160680 |Model #: LET-2Diphragm tank features: Easy installation, No Mainteance, 100PSI maximum working pressure. Company 5 year warranty

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.
