LWZ 303/403 Integral/SOL

The LWZ 303/403 is a heat pump specially designed for energy-efficient houses. It offers the standard functions of DHW and central heating, together with an additional ventilation function. Firstly, it provides you with enough heat, which it extracts from the air outside. Secondly, it provides DHW and regulates the complete air management of the accommodation. With its innovative countercurrent heat exchanger, it extracts up to 90 % of the latent energy in the extract air and returns it via the ventilation system. This means that your home will hardly lose any energy at all as a result of ventilation. As a complete unit, the LWZ is equipped with a 200 litre cylinder and all the necessary control functions for the heating, ventilation and DHW operation. The LWA 303/403 SOL additionally offers the option of integrating a solar heating system.
