The ratio of water to the air inside the steel expansion tank is optimal at a 2/3rds water to 1/3 air. Tanks not equipped with a site glass need an Airtrol fitting. Located on the bottom of the expansion tank is a fitting. It has an air bleeder on the bottom of it.

To calculate the volume of a thermal expansion tank: Vt=Vs[(Dc/Dh)-1][(Prv+9.7)/(Prv-Pa-5)] Where: Vt= Minimum expansion tank volume. (gallon) Vs= System volume. (gallon)
Get a QuoteUsing the calculated acceptance volume and the calculated total volume select a tank from the chart to the right. Tank volume of the selected model must be greater than the calculated total volume. Tank acceptance of the selected model must be greater than the calculated acceptance volume. Note: Both the Tank Volume and the Acceptance Volume must be greater than the calculated volumes as indicated.
Get a QuoteThe hot water expansion tank is a two-gallon tank that hangs off of your hot water system or your boiler. It is used to absorb excess water pressure. When water is heated or a hot water faucet is turned off abruptly pressure builds from expanding water molecules.
Get a QuoteThe boiler expansion tank absorbs the expanding water by allowing the air in the expansion tank to compress this prevents the pressure from building and allows the boiler to heat and cool without too mush pressure building up. Removing the furnace relief valve from the boiler or plugging it so that it does not leak is a very bad idea this can ...

Get a QuoteMay 24 2019 · 6. Do plan for lowest fluid temperatures: In most hydronic heating systems expansion tank size and air side pressurization is based the assumption that the cold fluid used to fill the system in the temperature range of 45F to 60F. That is fine.
Get a QuoteNov 11 2014 · To properly size the expansion tank one needs to know the total system volume the maximum operating temperatures and the specific thermal fluid used in the system. First determine the total system volume including the heater the piping the user and the initial-fill volume of the expansion tank (the amount of thermal fluid required to meet the minimum level in the tank.

For this calculation you will enter the BTU/hr of your operation along with the efficiency of your boiler.
Get a QuoteJul 31 2015 · In Part 1 of this series we looked at where thermal expansion tanks are needed. When it is determined that a tank should be included in the plumbing system the next task is to determine the correct size for the tank. Referring to sizing tables in an expansion tank manufacturers catalog is the easiest method although not the best method for sizing thermal expansion tanks.
Get a QuoteIt is relatively simple to think in terms of kW. The higher the demand for hot water there is in a home the higher the kW of the boiler will need to be in order to increase the flow rate of hot water. The 24 to 27kW combi boiler will supply flats and small homes that have no more than 10 radiators and one bathroom.
