CTC GSi 600

Our most efficient ground source heat pump that adapts the heat to your home and produces new hot water as your consumption increases! With its user-friendly and clear touch display, it is easy to control. You can also connect the pump to your mobile phone so that you can, for example, tap into extra energy when the price of electricity is at its lowest.

CTC GSi 600 is one of Sweden's best heat pumps with a stylish design, integrated display and high-quality finish! In addition to being a very good heat pump, it will provide you with big savings and become a stylish part of your interior.

CTC GSi 600 has an integrated touch screen with a user-friendly interface where you can easily access all functions and can both swipe and scroll, just like on your smartphone. In addition, you can easily mirror the display on your tablet, mobile, etc. The colour touch screen has clear symbols and the option to switch languages, making it easy to adjust the heating and hot water or retrieve a wealth of operating data. The integrated automation system is climate-controlled and takes into account both the indoor and outdoor temperature.

Using inverter control, CTC GSi 600 automatically adapts to the property's power requirements throughout the year. When high output is required, the output increases. When less output is required, the compressor shifts to lower output. This means you will always achieve maximum savings (up to 85%).

The high seasonal coefficient of performance (SCOP) of CTC GSi 600 means that, over the course of the year, it produces five times as much energy as it consumes. The compressor and cooling components are enclosed in a separate soundproofed unit, which makes it extremely quiet, only 34 dB(A). Furthermore, the entire heat pump has very efficient insulation that minimises energy loss. CTC GSi 600 meets the requirements for an A+++ rating, which is the best possible energy rating a heat pump can have.

CTC GSi 600 automatically adapts to the existing borehole. This means that when you replace your old heat pump, your installation costs will be significantly reduced. In addition, the product has been given a new flexible collector connection that makes it even easier to install.

CTC GSi 600 is equipped with a highly efficient flow-through heater, which produces over 300 litres of DHW. CTC GSi 600 is available in three power ratings and is suitable for both small and large residences.

With smart accessories, you can easily add solar heating, set up a water-jacketed stove or your existing water heater so that they too can contribute with heat. Or why not connect your pool so you can also enjoy the warmth during the summer?

CTC GSi 600 has internet connectivity as standard. You can control your product by using the myUplink app on your mobile phone. It is also equipped to connect to Alexa, Google Home and the future power grid (SmartGrid).
