Since 1976 we are dedicated to the production and sale of products aimed at the hvac and comfort.

About us

Our production activity is focused on the manufacture of biomass boilers, steel and cast iron gas or diesel oil boilers, heat pumps, domestic hot water cylinders, solar systems and oil burners. 


As a result of several years of research, we have developed a new technology to burn biomass, creating a range of boilers with the highest performances.

Keeping to our philosophy of innovation with meaning, we set out with this range to bring consumers who are committed to renewable energies, an alternative that is much closer to the highest levels of biomass technology at a reasonable price for a more sustainable environment.


We have been part of MONDRAGON corporation since 1998, together with another 257 autonomous and independent businesses and cooperatives, with production subsidiaries and corporate offices in 41 countries and sales in more than 150.
We therefore belong to the most important business group in the Basque Country, which is the tenth biggest company in Spain by number of employees and turnover.

Strong commitment to excellence

FAs a result of Domusa Teknik's commitment to a management model which is directed towards people participation and towards the customer, in 2010 we obtained the Silver Q for excellence in management.
