Consists of compact brine-to-water heat pump, WWSP 229E built-under domestic hot water cylinder and connection kit for quick and easy connection of the individual components to the heating system.
Compact brine-to-water heat pump
Heat pump for heating purposes for indoor installation with integrated WPM EconPlus. Sound-optimised through insulated metal casing and double vibration-isolated compressor. Integrated solid-borne sound insulation for direct connection to the heating system. Economiser for high coefficients of performance (COP). Sensor monitoring of the refrigeration circuit for a high degree of operational safety and integrated thermal energy metering (display of the calculated quantity of thermal energy 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). Compact design with domestic hot water preparation and integrated components for direct connection of an unmixed heating circuit (must not be used for bivalent systems):

• Built-in pipe heater (2/4/6 kW) can be used for reheating domestic hot water up to 60 °C and as a stand-by for heating operation

• Electronically regulated heat circulating pump (energy efficiency class A, observe the free compression)

• Domestic hot water loading pump

• Expansion vessel (24 l) and safety module

Integrated brine components enable direct connection of the heat source:

• Brine circulating pump (observe the free compression)

• Expansion vessel (8 l)

• Safety valve and pressure gauge

Built-under domestic hot water cylinder
Nominal capacity 227 l, bare-tube heat exchanger (internal) - heat exchange surface 2.9 m², steel cylinder (with special internal enamelling) with protection anode, polyurethane insulation with minimal standby losses. Soft starter (from 9 kW), integrated flow and return sensor; external sensor (standard NTC-2), dirt filter for brine circuit included in the scope of supply. Brine circuit manifold must be ordered separately.
