for KÖB & Viessmann biomass boilers


KÖB boiler– but no one really knows how it works?

I can help.


We offer service, remote access solutions, retrofits, training, and control system upgrades.

All from a single source.


15+ years of experience. Tailor-made solutions. Personal. Independent.

Whether it’s a single boiler system or a networked cascade,

I provide personal, manufacturer-independent consulting and solutions

precisely tailored to the needs of each installation and operator.

 Why Me

I’m Mathias Spinotti, former technician and training manager at KÖB (Viessmann).

Today, I run a specialized service center for wood heating systems and operate my own company focused on KÖB retrofits, custom solutions, and remote maintenance.

I know these systems inside and out – from the Pyromat to the Pyrotec – and I understand exactly what matters when it comes to maintenance, combustion, troubleshooting, and modernization.

Customer Feedback:

“Mr. Spinotti was able to analyze our system remotely and found the problem within 15 minutes — our installer was impressed.”

— Municipal technician from Bavaria

Customer Feedback:

“Thanks to Mr. Spinotti, our Pyrot boiler is running reliably again — our regular maintenance company would never have found the issue.”
