TERRASTAR ground source heat pumps

TERRASTAR ground source heat pumps

The TERRASTAR heat pumps work with ground - water system (drawing residual heat from earth the temperature of which is subsequently increased by pressure and used for hot water production) belongs to the new generation of highly efficient heat pumps. When combined with floor and wall heating or large-scale radiators, it shows tremendous financial efficiency. The TERRASTAR heat pumps supply stable output with high performance factor which also allows for installation in colder areas. The TERRASTAR heat pumps stand out for their exceptional output in the range from 5 to 41 kW. In case higher outputs are needed, heat pumps can be connected in a form of a cascade. A huge advantage of the TERRASTAR generation is an accomplished acoustic insulation which ensures very silent operations.

Maximal equipment

The TERRASTAR heat pumps have the best possible equipment which contains:

  • Integrated circulatory pumps.
  • Heat source reserve.
  • Outlet and sophisticated functions for hot water production.
  • Equithermal regulation of temperature.
  • Hosepipes solution to moderate vibrations.


The above-standard model TERRASTAR Plus comes with a module for passive cooling.


The equipment of the TERRASTAR Combi heat pumps contains also built-in hot water tank with the capacity of 190 litres. The compact solution of the TERRASTAR Combi heat pumps does not even take an extra 0.5 m2 space for installation. The TERRASTAR Combi is available in the output range from 5 to 11 kW.

The manipulation of the TERRASTAR heat pump

The manipulation of the TERRASTAR generation heat pumps is very simple as in other heat pumps products - the heat pumps are operated by well organised display and simple graphic symbols. The control system especially designed for heat pumps provides for all functions necessary for up-to-date heating systems. Heat pumps can be also controlled by Room – manager which allows for full control by means of computer, mobile phone, or web interface in internet browser.

Heat pump control

Room - manager control unit

The TERRASTAR heat pump is controlled by an easy-to-use Room - manager control unit, which can be placed anywhere inside the heated building. This control unit monitors operating stages of a heat pump and it can be used to regulate the heating and hot water heating.

Web interface in the Internet browser

All our heat pumps are equipped with regulator (CP-1051) which contains a WEB - server. This regulator is a network device with its own IP address. It is possible to access the regulator remotely through the IP address and to view the web interface of the regulator control panel or the heat pump control panel in the internet browser. This connection can be made by means of PC, laptop, tablet, smart phone, etc. Heat pumps can be thus remotely controlled via these devices. The web interface of the WEB-server is very simple and intuitive, a heat pump can be thus controlled remotely.

Control by means of mobile phone

The PZP heat pumps can be also controlled via SMS commands using any mobile phone. The only requirement is to purchase a modem which is available in the section of optional accessories for your heat pumps. You will also need a SIM card to avail of this type of control.
