Expansion Tanks | Rite Engineering & Manufacturing

Sizing expansion tanks: The following information is required: (a) Total system gallons (boiler + piping + heating coils). (b) Fill water temperature (use 40-50 degrees F. for most applications). (c) Maximum hot water operating temperature (d) Boiler relief valve setting (most new Rite Hot Water Boilers have 125 PSI relief valve settings).
