The perfect replacement pump

The Panasonic LZ25 has dimensions and a design that is made to simplify the choice of air heat pump when replacing an older model from, for example, Panasonic. The height of the heat pump’s inside is the same as on the older Panasonic models CKP and DKE. This means that your current location can be maintained, such as over the front door; something that’s difficult as modern heat pumps has generally become bigger. Also, the brackets behind the air heat pump need not be replaced and the pipe size is identical. Investing in a new air heat pump after 10 years is often a good investment. Today’s air heat pumps have significantly higher efficiency that benefits both the environment and your wallet, and comes with a range of new features such as maintenance, timer setting, remote control and better air purification.

Operation down to -35 ° C

Panasonic air heat pumps are designed for our Nordic climate, and the LZ25TKE is designed to provide high energy efficiency and provide clean heat even at an outdoor temperature of -35 °C

The new refrigerant

R32 is the refrigerant that replaces R410A, which will be phased out due to EU environmental requirements. This will happen up until 2025. The Panasonic LZ25TKE “Retro Fit 249” has the refrigerant R32 with a better ability to move energy.

Energy class

Thanks to the refrigerant R32, the heating system is very efficient and receives energy class A ++.

Maintenance heat

The Panasonic LZ25TKE has the function of maintenance heat that fits the home and other places where you want to keep a lower temperature during the winter season. It can be set at 8 °C or 10 °C.

Compatible with remote control

As an option, the Panasonic LZ25 can be remote controlled, allowing you to control your air heat pump from anywhere, using an app on your phone or tablet.


The Panasonic LZ25TKE is equipped with the Panasonic Econavi system, which makes the air heat pump’s environmental impact small and contributes to economic savings. Econavi can feel the weather, whether it’s cloudy or sunny, even if it’s night or day and adapts to the conditions. For example, if the air heat pump should be set to heat, it will feel if it’s dark or cloudy and increase efficiency. When the sun arrives, it sends signals to reduce the warming. It’s energy smart and the Econavi system detects whether the heat pump consumes unnecessary energy and reduces the heating equivalent to 1 °C. The system works similarly to cold as well as heat.

Inverter control

It is a speed regulation, which means that when the heat pump reaches the desired result, the heat pump automatically adjusts the temperature to keep it even. This means that electricity consumption is kept down, which is economical for both the household economy and the environment.
