Advanced functions
With our wide range of accessories, the heat pump can offer a wide range of functions for heating, ventilation and solar electricity production. Click on the “Accessories” tab above to read more about the different accessories offered.
NIBE Smart Price Adaption
With Smart Price Adaption (SPA)*, the heat pump will monitor the prices on the Nordic NordpoolSpot electricity trading exchange and can reduce the variable electricity cost of your electricity bill by 5–10%. The heat pump then works the most when the electricity costs the least, and vice versa. To activate the function, you need to be connected to myUplink and have a variable rate electricity contract per hour. Your heat pump gets information on the electricity prices for the coming 24-hour period and then adjusts its operation based on the price and your expected heating and hot water needs. *Requires a variable hourly rate electricity contract
Integrated hot water heater
The hot water heater built into the heat pump is insulated with environmentally friendly foam for minimal heat loss. Accessories for larger hot water volumes can be connected.
High hot water capacity
Provides up to 264 litres of 40 degree water.
WiFi/myUplink
Using the Internet and the myUplink app, you get a quick status overview of the heat pump and the heating in your home. This flexible solution enables you to easily monitor and control heating and hot water production. In the event of a malfunction in the system, you will promptly receive a push notification and e-mail notifying you of this. With myUplink, you can use the smart services Weather Forecast Control for more even heating and operation, and Smart Price Adaption*, in order to further reduce energy costs. You can automatically receive ongoing software updates for optimal operation and the latest features. The WiFi connection also enables you to connect the heat pump to your already smart home. *Requires variable hourly rate contract
Natural refrigerant
The refrigerant moves energy in the form of liquid or gas in the heat pump. This heat pump works with a natural refrigerant that has a very low GWP (Global Warming Potential) value, for a sustainable climate and nature footprint.
