Heat & Glo: Cosmo Insert 35

The modern Cosmo look, sized for a bigger masonry opening and a bigger room.

Quick Facts

• Heating Capacity: 750–1,500 sq ft
• Fuel: Natural gas; propane with a conversion kit.
• Controls: Touchscreen remote with thermostat.
• Fan: Included

Who It’s For

A wide brick fireplace looks odd with a small insert floating in it. You want the new fire to fill the opening you already have. The Cosmo Insert 35 is the larger of the two Cosmo sizes, made for bigger fireplaces and the larger rooms around them. Choose it when your existing opening is generous and you want a contemporary fire that looks built for it.

What Makes It Special

The bigger firebox gives the glass bed and its flames more width, so the fire reads clearly from across an open living area.

It comes with a variable fan and a touchscreen thermostat remote, plus battery backup. Finish it with glass media in clear, cobalt, amber, red, ebony, or fog, and add driftwood or river rock if you want texture.

Possible Downsides

• The front, surround, and glass media are separate, required choices.
• Propane requires a conversion kit. The insert ships set up for natural gas.

If your fireplace is too big for a small insert and you want a modern look, the Cosmo Insert 35 is the right decision. A big old fireplace finally looks intentional.

Choose a firescreen, Halston arched, inside-fit, or Iron Age front, a matching surround, glass media in six colors with optional driftwood or river rock, a reflective black glass liner, and a wood or non-combustible mantel shelf.
