A wood boiler is a real investment, and pricing depends on more than just the boiler itself. Model, size, installation, and the components that complete the system all move the total cost. You'll find current equipment prices for the most common wood boiler models below — but the boiler unit is only one line in an installed system, so treat those as a starting point rather than the whole project.
This guide breaks down what actually drives the cost of a wood boiler system, so you know what to ask about — and what to have ready — before getting a real quote.
What determines the cost of a wood boiler system
Four things drive the total cost of a wood boiler project: which model and size you need, what your installation actually requires, which additional components complete the system, and local labor rates. None of these are fixed — they depend entirely on your building, climate, and how the system will be used.
That's why this page shows equipment prices but not a single installed-system number: a full-system figure without your square footage, distribution method, and site details attached would be a guess, not a quote. The sections below walk through each factor so you know what you're actually paying for.
Boiler family and size
MBTEK's four wood boiler families sit at different price tiers, largely driven by automation and output range:
- PRO: the simplest, most affordable entry point — manual-feed, no electricity required, and the only family that also burns coal or briquettes. Two models, up to 3,000 ft².
- UNI: MBTEK's featured wood gasification boiler and the most common choice — smart controller, 86%+ efficiency, four models covering up to 8,000 ft².
- TITAN Lambda: the most advanced option — automatic ignition, lambda oxygen-sensor combustion control, up to 95% efficiency.
- UNI Industrial: the same UNI platform scaled up for farms, large workshops, and commercial buildings, with the widest price range of the four families (up to 3.4 million BTU).
Within any family, larger models cost more than smaller ones — bigger BTU output means more steel, a larger heat exchanger, and more capacity overall. Getting the size right matters for cost as much as for comfort: oversizing pays for capacity you don't need, and undersizing means the boiler works harder than it should.
Wood boiler equipment prices
The grids below show current Shopify prices and active MBTEK promotional pricing for the two most common residential wood boiler lines — the entry-level PRO and the featured UNI. These are equipment-only prices for the boiler itself, not complete installed-system prices. Installation, chimney work, a buffer tank, distribution, and labor are separate — see installation costs below.

Installation costs: chimney, mechanical room, and labor
Installation is often a bigger swing factor than the boiler itself. Three things drive it:
- Chimney work: an existing, correctly sized chimney keeps installation simple. A new chimney, or one that needs to be resized or relined for correct draft, adds real cost — see the chimney draft guide for how draft is calculated.
- Mechanical room prep: clearances, combustion air supply, flooring, and code compliance for an indoor wood boiler installation.
- Labor: rates vary significantly by region and installer, and a wood boiler installation is more involved than swapping a like-for-like appliance.
None of this is one-size-fits-all. An installation into an existing mechanical room with a usable chimney costs meaningfully less than a full new mechanical-room build-out.
What else adds to total system cost
The boiler is rarely the only line item on a wood boiler project. A complete system commonly includes:
- A buffer tank — recommended for most systems to store excess heat and reduce cycling; see the wood boiler buffer tank guide.
- A domestic hot water tank — every MBTEK wood boiler family can support DHW through an indirect tank, when the system is designed for it.
- Hydronic distribution — radiant floors, radiators, or fan coils, if not already in place.
- Controls — UNI-line boilers can add the UNI Boiler Wi-Fi Module for remote monitoring, and smaller models often bundle the Boiler Station (protection valve, pump, and thermometer in one).
Pricing the boiler alone and adding these later almost always costs more than planning the full system up front.
MBTEK recommendation
Get a real number, not a guess
The equipment prices above cover the boiler unit. Because total cost depends on model, size, installation, and system components together, MBTEK confirms full installed-system pricing through the product pages and a specialist conversation rather than a flat number on this page.
To get an accurate quote quickly, have these ready: approximate square footage and heat loss, whether off-grid operation matters, your existing chimney situation, and your distribution method.
- Compare models: Browse the wood boiler lineup to see current pricing by model.
- Understand the mechanism first: Read how a wood boiler works if you're still comparing options.
- Get sizing help: Use the System Builder or contact MBTEK for a confirmed quote.
Buying checklist before requesting a quote
Before requesting a wood boiler quote, confirm these points:
- What is your approximate square footage and heat loss?
- Do you have an existing, usable chimney, or does one need to be built?
- Do you need off-grid operation, or is electricity available?
- What hydronic distribution will the boiler feed?
- Will you add a buffer tank and/or a DHW tank?
- Who will install the system, and have you gotten a labor quote?
Cost is the sum of a few real decisions
The cost of a wood boiler isn't one number — it's the sum of the model and size you choose, what your installation requires, and which components complete the system. Understanding those factors is what makes a specialist quote fast and accurate instead of a guess.
If you're ready to move forward, compare models or talk to MBTEK with your project details in hand.
