Optimal matching of the control behaviour to the high efficiency pump and the heat exchanger guarantees perfect stabilisation of the outlet temperature regardless of flow changes. Uniform and interchangeable G3/4“ connections reduce the assembly effort.

FRISTAR3-WP: A heat exchanger with twice the heated length has been integrated for systems with low flow temperatures. The FRISTAR3WP therefore achieves the specified draw-off rate of 30 litres/minute at half the temperature differential between the cylinder flow and DHW outlet (compared to FRISTAR3).
