Heating and domestic hot water preparation package
Heat pump and WWSP 229E built-under hot water cylin-
HPK ..TEW
Consisting of compact brine-to-water heat pump, WWSP 229E built-under hot water cylinder and connection set 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. Econo-
miser for high coefficients of performance. 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). 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 (efficiency class A, observe the free compression)
• DHW loading pump
• Expansion vessel (24 l) and safety module
Integrated brine components enable direct connection of the heat source:
• Brine circulating pump (note the free compression)
• Expansion vessel (8 l)
• Safety valve and pressure manometer
Built-under hot water cylinder
Nominal volume 227 l, tube heat exchanger (internal) – Heat exchanger area 2. 9 m², steel cylinder (with special internal enamelling)
with protective anode, polyurethane insulation with minimal stand-by 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.
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 1¼ ⬙.

Heat output and COP according to EN255 (EN 14511) at B0/W35 (B0 = brine inlet temperature 0 °C, W35 = heating water outlet temperature +35 °C) .
With borehole heat exchangers, the free compression values in the device information are to be adhered to (max. heat exchanger depth at DN 32:
80 m)! Note: A minimum buffer volume of the heating system of 10% of the heating water flow must be ensured either by a buffer tank or other
suitable measures! In heat pump heating systems, the underfloor heating can assume the function of the buffer tank connected in series if no indi-
vidual room regulation is required or if regulation is carried out based on the room temperature. In this case, the heating surface of the reference
room must guarantee the minimum heating water flow rate.

Reference room regulation
Smart RTC (Room Temperature Controller)
RT Econ
Reference room controller for use in combination with compact brine-to-water heat pumps HPK 7, 9 and 11TEW. The controller measures
the temperature difference between the actual room temperature and the set temperature, and communicates this to the heat pump
manager. The return set temperature is calculated on the basis of this difference. The ~230 V voltage supply (2-core) and the bus cable
(2-core, screened) must be provided by the customer.
Additional functions:
- „Operating mode“ button – switches between automatic and summer operating mode
- „Rapid heating“ button – 20, 40 and 60-minute rapid heating (blocks DHW)
- Warning signal displayed if a heat pump fault occurs
