Its patented ignition and air-control systems feature top-quality functionalities and can efficiently heat large areas up to 1,500 square feet while still emitting clean air, as it steadily burns. This fireplace's efficiency level is well matched by its environmental credentials with an EPA certification of 1.91g/hr. 

An exclusive product feature that contributes to the wood fireplace's extreme durability and excellent heating is the addition of cast-iron panels that both line and protect the durable stainless steel firebox. This allows the wood fireplace to both retain and transfer heat more efficiently, resulting in long-lasting warmth. 

With its ability to deliver advanced heating technology, the Astra 24 is the versatile zero clearance wood fireplace of choice for modern homeowners.


Patented Automatic Air Control

This patented, user-friendly mechanism automatically reduces the amount of combustion air introduced during ignition to the desired burn rate setting. The result is a beautifully consistent fire burning to its full capacity.

Premium Blower (130 CFM)

This powerful yet whisper-quiet system effortlessly distributes heat over significant distances. As the combustion progresses, the high-quality blower automatically activates and is set using the variable speed controller.

The Astra 24 comes with a high performance 130 CFM blower kit, which has an electrical rating of 115V, 60 Hz, and 56 W. A variable speed control (rheostat) and a heat sensor (therm-o-disc) are included with the kit. WARNING: Do not install a substitute blower.

Removable Ash Lip

Offering another layer of protection against ashes, this removable accessory can be attached below the door to prevent spills when the fireplace is opened.

Chimney Sweeping Cap

Located on the baffle, this convenient feature allows the chimney to be easily accessed for cleaning, without requiring the removal of any additional components.

Unique Door Operation

Our finely crafted door handle has an ergonomic design and keeps the door shut by means of a latch for a secure operation.

Hot Air System
Enjoy watching the beauty of your fire for longer thanks to this advanced design feature. Pre-heated air is forced onto the glass viewing pane, keeping it clean from soot even while burning at low temperatures.

Innovative Baffle Design

Most EPA units on the market feature secondary air tubes that hamper access to the chamber when filling it with wood and require constant maintenance and regular replacement. Instead, Supreme's products have a unique design that allows secondary air to enter through a perforated baffle offering an unimpeded viewing area to the fire all while increasing the efficiency and prolonging the combustion.

Patented Secondary Air Control

This patented control introduces a variable amount of secondary air into the firebox via a downward path that mixes with the rising gases of the wood. The result is a unique, appealing arrangement of flames that prolongs the combustion, increases the efficiency of the fire and minimizes the amount of emissions released.

Cast-Iron Panels

An extra layer of durability and strength is provided with these cast-iron panels that line Supreme's heavy-duty stainless-steel firebox. In addition to providing a quicker and more uniform heat transfer, the cast-iron prolongs the combustion by retaining warmth.


While most manufacturers only offer a two-year-warranty (or less) for their refractory-brick fireboxes, we stand by Supreme's cast-iron paneled chamber with a market-leading 10-year guarantee.
