Technical data
- Flextherm PS-H: Steel vessels to reduce the on/of cycling of the heat pump as buffer vessel or to protect Flexcon expansion vessels on elevated temperature systems.
- Flextherm PS-H+: Buffer vessels for use in smaller, closed heating installations.
If a heat pump produces more heat than the heat requirement at a certain time, it’s recommended to buffer this excess heat and meanwhile reducing the on/off cycling of the heat pump to increase the product life time. When the energy is stored in the buffer the complete system will be more consistent and easier to control by eliminating the temperature fluctuations.
