Package solution for compact brine-to-water heat pumps
Max. flow temperature 58 °C
Casing colour White (similar to RAL 9003)
HPK ..TEW
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. Econo-
miser 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 prepa-
ration 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 enamel-
ling) 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.

Heat output and coefficient of performance (COP) according to EN 14511 at B0/W35.
HPK 11TEW: Brine temperatures over 10 °C are likely during operation and the use of a SIK 11TE with a 400 l domestic hot water cylinder (WWSP
880, WWSP 442E) is recommended. 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 rate 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 individual 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 U
The reference room 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 domestic hot water)
- Warning signal displayed if a heat pump fault occurs
