Cimm 40486 RP250 Flat Heating Expansion Vessel 10L 180 Degree
Genuine Cimm 40486 flat expansion vessel, 10 litres, from the RP250 range (250 x 438mm footprint), with a 180 degree connection, for sealed heating circuits in boilers and heat pumps.
What it does
Water expands as it is heated, and in a sealed heating circuit that expansion has nowhere to go, so pressure rises until the safety valve lifts. The vessel takes up the extra volume against a pre-charged air cushion and holds system pressure steady. Cimm use a fixed rubber diaphragm, designed to hold its air pre-charge at the higher temperatures a heating circuit sees. The flat body is made to fit inside a boiler or heat pump casing, where a round vessel will not go. A vessel that has lost its charge is the usual reason a system keeps losing pressure or dumping through the relief valve.
Where it fits
Wall-hung boilers and heat pumps that take a flat expansion vessel, and other sealed heating circuits; absorbs the expansion of the system water so pressure stays within limits; 10 litre, RP250 flat body 250 x 438mm, 180 degree connection.

- Capacity 10 litres
- RP250 flat body, 250 x 438mm
