hot water expansion tank

Yes. On the cold line between the tank and the check valve. Make sure and use the right tank....for potable, open systems, not for hydronic systems

Hot water expansion tanks

All unvented water heaters sold in the UK are required to have an expansion vessel by the Water Regulations. The expansion vessels are invariably on the cold feed pipe, so that the diaphragm is not exposed to hot water.
