• 3-temperature mixer
• The 3-temperature mixer is used in conjunction with a buffer storage tank, which can be heated by a solar system, a solid fuel boiler or a conventional boiler.
• If the consumer only requires a low temperature level, such as with underfloor heating, the 3-temperature mixing valve initially draws the supply water from the middle section of the storage tank. Only when the temperature in this section is no longer sufficient is water from the top, hotter section of the storage tank used.

By using two storage zones for two different flow temperatures, the energy in the buffer tank can be used more efficiently. The return temperatures are low, and the temperature stratification in the buffer tank is maintained.
