Lopi – Radiant Plus Medium GSB Gas Fireplace Insert

Lopi Radiant Plus® Medium GSB Gas Fireplace Insert

The Lopi Radiant Plus® Medium GSB is a versatile, energy-efficient gas fireplace insert designed to transform your existing wood-burning fireplace into a reliable and stylish heating solution. Perfect for mid-sized living spaces, this model combines efficient heating performance with a beautiful flame display and modern convenience.

Efficient Heat for Mid-Sized Homes

Producing up to 25,000 BTUs, the Radiant Plus® Medium GSB can comfortably warm up to 1,250 square feet. Its combination of radiant heat, which directly warms people and objects, and natural convection heat, which circulates throughout the room, ensures even comfort all season long.

GreenSmart® Basic Ignition System

The GSB (GreenSmart® Basic) system makes this insert highly efficient by eliminating the need for a continuously burning pilot light. The pilot automatically ignites when the unit is in use and turns off when it’s not, saving fuel and reducing operating costs. This smart technology offers energy savings without sacrificing performance.

Realistic Fire Presentation

Equipped with the Dancing-Fyre™ burner and a hand-detailed Classic Log Set, this insert creates the look and feel of a traditional wood fire. Flames rise naturally around the logs, while glowing embers add depth and realism. The medium-sized ceramic glass window provides a wide, clear view of the fire, making it the centerpiece of your living space.

Customizable Design Options

The Radiant Plus® Medium GSB can be tailored to match your home’s décor. Choose from multiple face styles, trims, and optional firebacks to create a look that blends seamlessly with your living room. Add-ons like a convection fan or remote control provide enhanced comfort and convenience.

Built for Performance & Comfort

With efficiency ratings approaching 87%, this insert maximizes fuel use while delivering steady, dependable heat. Flame turndown settings allow you to reduce heat output on milder days while keeping the beautiful flame display intact, giving you flexible comfort year-round.
