WebExpansion tanks or thermal expansion tanks come in two sizes, 2-gallon and 4.5-gallon. The size that you need depends on the size of your water heater and the pressure of the water that’s running to it. As the water in your water heater heats up, it expands. That’s why expansion tanks are referred to as thermal expansion tanks.
WebTheoretical basis of the calculation: V tank = (V sum × e) / ( (P max - P o ) × (P max + 1)) V sum – heating System Volume; e – volumetric coefficient of expansion; P max – maximum pressure; P o – initial pressure.
