Answers

Frequently asked questions

What is TITAN Lambda and how does lambda combustion control work?

TITAN Lambda is MBTEK's most advanced wood gasification boiler. An oxygen sensor continuously reads combustion conditions and a servo motor automatically adjusts combustion air in response, keeping the burn efficient across the load range. On the 110K model, flue gas temperature is 100°C at minimum output and 160°C at maximum output. On the 175K model, it is 95°C at minimum output and 150°C at maximum output.

How efficient is TITAN Lambda?

Up to 95% — the highest efficiency figure in MBTEK's wood-boiler line, driven by automatic lambda-sensor combustion control rather than a fixed fan setting.

What temperature does the secondary combustion chamber reach?

MBTEK's TITAN Lambda specifications document a lower combustion chamber temperature of 1,000–1,200°C. This figure comes from MBTEK's product specifications, not the user manual, which doesn't separately publish a secondary-chamber temperature.

How does TITAN Lambda compare to UNI?

Both are wood gasification boilers, but TITAN Lambda adds automatic ignition and lambda-sensor combustion control for up to 95% efficiency, versus UNI's smart-controller-managed 82% minimum efficiency. UNI is sold across more size steps; TITAN Lambda is sold as a single product with 110,000 and 175,000 BTU variants.

Can TITAN Lambda provide domestic hot water?

Yes — TITAN Lambda's integrated hydronic controls can manage a domestic hot water tank alongside space heating.
