Ideal Expansion Vessel - 35L
Ideal Expansion Vessel - 35L
The Ideal Expansion Vessel - 35L is a heating expansion vessel. Compatible with the Ideal Logic Air and HP290 heat pump ranges.
Water expands as it heats, and a sealed system needs somewhere for that expansion to go. The vessel absorbs it and holds the system pressure steady; undersize it and the pressure relief valve discharges every time the system comes up to temperature.
