12 Ltr Expansion Vessel

Or Register

The main purpose of an expansion vessel is to compensate for the variation of the volume of water due to the variation of the temperature in heating systems. For example the water heating up from 0°C to 100°C increases in volume by about 4.5%. This means that there should be a space inside the system that can keep the increased volume of water.
