Low-temperature brine-to-water heat pump
Universal design
SI 22TU
Heat pump for heating purposes for indoor installation with integrated WPM EconPlus. Variable connection options for brine and
heating connections on the rear wall of the casing. Integrated solid-borne sound insulation for direct connection to the heating system.
Sound-optimised through insulated metal casing and double vibration-isolated compressor. High COPs through economiser and com-
pliance with the requirements of EN 14511 for larger volume flows on the heat consumption side. Sensor monitoring of the refrigerating
circuit for high degree of operational safety; integrated thermal energy metering (display of the calculated thermal energy volume for
heating and domestic hot water preparation on the WPM EconPlus heat pump manager). The control panel is integrated into a brown-
red design screen and can also be used as wired remote control using the wall mounting set (special accessories MS PGD). Universal
design with optional DHW preparation and the option of flexible expansion for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
Soft starter, load contactor for brine circulating pump, integrated flow and return flow sensor; external sensor (standard NTC-2) and dirt
filter for brine circuit included in the scope of supply.
Brine package and brine circuit manifold must be ordered separately.
Lower operating limit heat source (heating operation) -5 °C ; Upper operating limit heat source (heating operation) 25 ° C ;
Refrigerant R407C ; Connection heating 1¼ ⬙ ; Heat source connection 1½ ⬙.

High-efficiency brine package for brine-to-water heat pump
with one performance level
SZB: Breather
SZB: Expansion vessel
High-efficiency brine circuit accessory package consisting of a pre-assembled connection module (expansion vessel connection, quick-
vent valve, 3 bar safety valve and pressure gauge) with cap valve that can be shut off for easy installation of the SWPR 200 low-pressure
controller for the leakage monitoring of the brine circuit (available as special accessories), 18 litre / 0.5 bar admission pressure expansion
vessel, ball valves, large-capacity breather with micro air bubble deposition and electronically-controlled brine pump with 0 – 10 V out-
put signal (energy efficiency class A) for ground heat collectors according to the planning documentation (without brine circuit manifold
and pipework). If the dimensions deviate or if borehole heat exchangers are used, the free compression must be checked.
