Simple to use yet

Powerful controller

Our boiler is outfitted with the most recent controller, allowing you to automatically control the operation of the fan with smooth modulation, the central heating pump (CH), and the hot water pump (DHW). You will also be able to program the combustion process based on the fuel type and operating conditions.

On the coldest days

A heat source you can count on

This boilers' clean, full combustion extracts the greatest amount of heat with a guaranteed efficiency of 86 percent or more using micro air metering in the lower and higher fire chambers. This multi-stage air supply system to the primary and secondary combustion chambers ensures that the emitted gases are completely burned.

Burning time on one load

Up to 24 hours

The spacious fuel loading chamber and variable heat output from 30 to 100 percent are features you will only find in UNI. It is also highly efficient with an exhaust gas maximum temperature of less than 260°F / 300°F. When combined with a buffer tank, you can access the gasification mode, which allows you to extract the most energy from your solid fuel.

Uni 40 boiler

I am loving the boiler, heating garage and house with in floor tubing.The boiler is performing great!

Uni 40 boiler

I don’t think they are csa approved just yet but other then that good shipping, took longer then promised but the unit itself is good it has a big burning chamber, computerization makes it burn at consistent temperatures

Uni 40

So far it’s been fantastic, does 2600 sq house along with domestic hot water. Was a little confused when it came in with a euro plug but customer service was extremely helpful with very quick responses.

Satisfied about product but...

Product seems very good even if they are the cheapest on the market. Although i must say that installation instruction are weak and support is bad. You must have knowledge on installing and parametering things. I highly recommand for advanced or expert consumers.

Uni 40

the boiler is just great and works great. exactly what I was looking for and could not find in Canada, to my great regret. a slight delay in logistics, but this is such a problem everywhere in North America. very good customer service. I am very pleased with the purchase of the boiler.

Frequently Asked Questions

Where can I find your dealers?

We don't have a dealership. Please speak directly with one of our sales agents via phone, chat, email or text message for more information.

Who will install my boiler?

Mbtek does not offer physical installation. You will need a hydronic plumber to connect the boiler to the water system and a chimney installer. Please contact us for any assistance.

Where can I find parts?

At this link. We have spare parts ready to ship the following business day.

How long does a fire last?

This will depend on the type of wood you are using. However, at the lowest settings, a fire can last up to 24 hours. We recommend using gasification mode, which ensures excellent combustion with a quick yet strong fire. We also recommend storing this intense heat in a buffer tank. This will allow you to diffuse the heat slowly as needed.

Do I need to purchase anything else with my wood boiler?

Just got it. Uninstalled.

Unit looks well built and was well packed for shipping. I’ll update my review when I’ve installed.

Great customer service

The product works great, we had a few questions about the wiring and the technician on the phone was able to answer all our questions and even offered to wait on the line while we wired up the thermostat to make sure everything worked correctly.

Well designed. Quality build.

We switch between burning pellets, cord wood, or coal depending on price fluctuations. The build quality is excellent. Nothing else on the market even competes.
