MBTEK UNI Wood Boiler

Main Features

  1. Fire Box

    The large loading chamber holds a full charge of wood, so you can go longer between reloads without sacrificing steady heat output.

  2. Burning time

    A single loading can burn for up to 24 hours, giving you steady heat overnight or through the day without constant attention.

  3. Smart Controller

    The controller automatically manages the fan, central heating pump, and hot water pump, and lets you set combustion options for your fuel.

  4. Heat exchanger

    A tubular heat exchanger pulls more heat from the flue gas before it leaves the chimney, so more of every fire goes into your home.

  5. Automated Fan

    Multiple fan speeds adjust combustion air automatically, helping the fire burn cleaner and steadier across a full range of heat output.

  6. Boiler Steel Frame

    A 5mm ASTM A106 steel frame with cast-iron grates and insulation is built to handle years of daily wood-burning without warping.

UNI wood boiler main features overview
UNI large wood boiler product overview

Thickness nearly 1/4"

UNI boilers use certified ASTM A106 steel with a powder-coated casing, cast-iron grates, 2" insulation, and thermal protection systems for durable, dependable performance year after year.

Powerful controller

The advanced controller automatically manages fan modulation, the central heating pump, and the hot water pump, while letting you program combustion settings based on fuel type and operating conditions.

A heat source you can count on

This boiler is clean, full combustion extracts the greatest amount of heat with a guaranteed efficiency of 86 % or more, using micro air metering in the lower and higher fire chambers.

Up to 24 hours

The large loading chamber and 30 to 100 percent heat output give UNI long, efficient burns, with low exhaust temperatures and optional gasification mode when paired with a buffer tank.

UNI Industrial FAQ

UNI Industrial Wood Boiler Frequently Asked Questions

Answers about UNI 150, 300, 500, and 1000 wood gasification boilers for commercial and industrial hydronic projects.

Which UNI Industrial model should I choose?

Approx. heating area: UNI 150 is suitable for up to 12,000 ft², UNI 300 for up to 17,000 ft², and UNI 500 for up to 24,000 ft². UNI 1000 requires project-specific sizing. Approximate coverage only. Final selection requires a building heat-loss calculation and MBTEK sizing review.

What buildings is UNI Industrial best for?

UNI Industrial fits large heated areas, farms, workshops, commercial buildings, and other high-demand wood gasification heating systems. Equipment access, fuel handling, and mechanical-room layout should be planned early for these larger-scale installations.

Can a UNI Industrial boiler provide domestic hot water and need a buffer tank?

Yes, UNI Industrial can support domestic hot water through an indirect tank, storage tank, or engineered hydronic design, and domestic hot water demand should be included in sizing since it can be a major load in commercial and multi-use buildings. Many high-demand wood gasification systems also benefit from a buffer tank, since a full wood burn can produce more heat than the building needs at that moment, and thermal storage can capture that heat and reduce cycling.
