Maxi Select’s modular construction makes for shorter lead times, resulting in a timely solution for both new installations and renovations. Easily connected to all types of piping, heat pumps, and district heating networks, its compact design can handle both domestic hot water and/or space heating, and accommodate additional heat exchangers and other functions, at capacities from 20 – 800 kW.

As with all Cetetherm products, efficiency, controllability, and sustainability go hand in hand. Maxi Select features optimal heat recovery and low return temperature, and is equipped with electronically controlled pumps for optimised energy use.

It can also be combined with our smart, IoT-connected Optimizer solution to automatically and intelligently prioritise heat sources at the lowest cost to energy companies, end-users, and the environment.
