Customer Success Stories
Hey, my name is Eric from Michigan with my MBTE 50 Phoenix boiler. This is the 170K unit. I'm using this for in-floor heat in my Barndominium, which is a 3,000 square foot home here in Michigan, which gets down to 5 degrees. And this just keeps up with my home. It does no problem heating a big two-story 3,000 square foot home. I love it. If you're looking to be off-grid, this is a good option for you.
Keeps my home warm with no problem, even at 5 degrees
Hear how Eric from Michigan heats his 3,000 sq. ft. Barndominium with a Phoenix pellet boiler.

ATLAS Pellet Stove Boiler
The ATLAS Pellet Stove Boiler is a compact, high-efficiency wood pellet heating solution designed for hydronic central heating systems. Unlike a standard pellet stove that only heats the room where it is installed, the ATLAS uses an integrated water jacket to transfer heat into your hydronic system for whole-home or light commercial heating.
With automatic combustion control, smart start and stop timers, built-in safety protections, and a modern indoor design, the ATLAS combines the look and convenience of a pellet stove with the heating performance of a pellet boiler.
Key Benefits
- Pellet stove boiler design combines room-friendly indoor installation with hydronic heating performance.
- Water-jacketed heating transfers heat into your hydronic system for central heating applications.
- High-efficiency operation helps maximize wood pellet fuel economy.
- Automatic pellet feed and airflow modulation adjust combustion based on heating demand.
- Built-in fuel bunker provides extended heating autonomy between refills.
- Programmable controller supports daily, weekly, and weekend start/stop schedules.
- Fast automatic ignition helps simplify startup and everyday operation.
- Integrated safety protections monitor water temperature, system pressure, and flame conditions.
- Easy maintenance access with quick-release side panels and a slide-out ash tray.
- Modern European design makes it suitable for visible indoor mechanical or living-space installations.

Answers
Frequently asked questions
What is the ATLAS Pellet Stove Boiler?
ATLAS is a compact residential and light-commercial pellet boiler. Its full water jacket transfers pellet heat into a hydronic system for space heating and, when properly connected, domestic hot water.
Is ATLAS a pellet stove or a pellet boiler?
ATLAS has the compact format of a pellet stove, but it is a boiler because it heats water for a hydronic system.
Is ATLAS a wood pellet boiler stove or a pellet stove furnace boiler?
ATLAS is best described as a wood-pellet boiler with appliance-style pellet-stove packaging. It heats water for hydronic distribution rather than heating a building only through direct room air.
Should I choose the 65 KBTU or 120 KBTU ATLAS model?
The 65 KBTU model covers up to 2,250 ft² and the 120 KBTU model up to 4,400 ft². These ranges are approximate; choose from a building heat-loss calculation, climate, insulation, and system design.
Can ATLAS heat domestic hot water?
Yes — ATLAS can support domestic hot water when connected to a correctly sized indirect water heater tank as part of the hydronic system.
How efficient is the ATLAS Pellet Stove Boiler?
Both ATLAS capacity variants are rated at over 94% efficiency.
What fuel does ATLAS use?
ATLAS uses wood pellets measuring 1/4–5/16 in in diameter.
What should I plan before installing ATLAS?
Plan for 120V/60Hz electrical service, a 4 in exhaust flue, model-specific combustion air, hydronic piping, pressure controls, pellet storage, and service access. Follow the ATLAS manual and local codes.
What maintenance does ATLAS need?
Use the slide-out ash tray and self-clean lift for routine cleaning, keep the pellet bunker supplied, and inspect the burner, flue, safety devices, and hydronic system according to the manual's schedule.
What buildings is ATLAS best for?
ATLAS is aimed at homes, workshops, garages, and light-commercial spaces that want compact, appliance-style pellet heat connected to a hydronic system.
How does ATLAS compare with Phoenix?
ATLAS is the lower-cost compact option with a 99 lb hopper and over 94% efficiency. Phoenix adds a larger hopper, up to 96% efficiency, self-cleaning support, and app control at a higher price tier.
