How it works

The LK HeatBooster is designed to provide supplemental heating in systems without an electric immersion heater, ensuring stable and efficient operation even during peak demand. When connected to the heat pump's controller,
it seamlessly integrates into the heating system, automatically activating when additional heat is needed – whether for domestic hot water or to support the overall heating system – to maintain optimal performance.

Customisable in size, capacity, and components, the HeatBooster is engineered for flexibility, making it easy to adapt to different system requirements. This application scheme illustrates how it functions within your setup, enhancing efficiency and reliability.
