The main purpose of an expansion tank is to compensate for the variation in the volume of water due to the change in temperature within the heating system. For example, water heating up from 0C to 100C increases its volume by about 4.5%. There therefore needs to be space inside the system to accommodate this increased volume of water.
Capacity: 24 litres
