Expansion Vessel Capacity

• A diaphragm type expansion vessel, conforming to the current issue of BS4814 will be required. The expansion vessel must be connected to the systems at a point close to the inlet side of the circulating pump. The expansion vessel volume depends on the total water system volume and the initial system design pressure. For any system an accurate calculation of vessel size is given in the current issue of BS5449 and BS7074 Part 1.
• The water content of the heat pump is given in the technical specification. Note a higher initial design pressure requires a larger volume expansion vessel.
• The charge pressure must not be less than the static head of the system, which is the highest point of the system above the expansion vessel.
• NOTE: Failure to ensure the correct vessel size could result in premature failure of the expansion vessel which in turn may adversely affect other components in the system i.e., circulating pump and diverter valve.

Capacity of Expansion Vessel

Where design information is not complete the following chart can be used for selecting the size of the vessel, it should be noted that the size given in the table takes account of fault conditions.

Safety Valve
A safety valve set at 3 bar must be fitted with the drain routed to the outside of the building. The drain must not discharge above an entrance or a window or any public access area, be clear of any electrical fittings and positioned so that any discharge can be seen.
