Was und Wie GmbH

We are there for the people of Nidwalden and Obwalden!

We need and consume energy every day. We heat our buildings for comfort and coziness, and we ventilate our rooms for an optimal indoor climate. If ventilation and heating are dirty or not optimally regulated, we consume energy unnecessarily. We are the professionals for cleaning and maintaining fireplaces, heating and ventilation systems.

We measure the emissions of oil, gas and wood fires in all output ranges. This allows us to show you how efficiently and cleanly your heating system is working or where there is still potential for optimization. For official measurements, we prepare the official measurement report and take care of the correspondence with the authorities for you.

Do you need to replace your heating system? We can provide you with a complete offer for a heating renovation in accordance with MuKEn. Pellets are a CO2-neutral, affordable and 100% alternative way of heating. We support you in replacing your heating system from planning, installation and commissioning through to maintenance and cleaning.

We help you to use energy cleanly and efficiently.

It is very important to us that you can understand in our work WHAT we optimize and HOW we optimize.
