Kozy Heat Springfield 36 Gas Fireplace
AUTHORIZED DEALER The Kozy Heat Springfield 36 is a 36-inch direct-vent gas fireplace designed for retrofit installation inside an existing fireplace opening — turning a drafty wood-burning fireplace or an outdated older gas unit into an efficient, clean-burning modern heater. With a modulating 18,000–35,000 BTU/hr burner, up to 79.5% efficiency (highest in Kozy Heat's residential lineup), included Komfort Kontrol thermostat remote, and a generous 29-5/8" × 21-13/16" viewing area, the Springfield 36 is engineered as the smartest upgrade path for homeowners who already have a fireplace they want to bring into the modern era without rebuilding the wall.
What Makes the Springfield 36 Different?
The Springfield 36 belongs to a specific category in the Kozy Heat lineup: direct-vent fireplaces designed to retrofit into existing fireplace openings. This is meaningfully different from new-construction fireplaces like Kozy Heat's Nordik series. Where new-construction units assume you're building a custom wall around the firebox, the Springfield 36 assumes you have an existing fireplace cavity (likely from a wood-burning fireplace or an older gas unit) and want to insert a modern, efficient direct-vent unit into it.
Three design choices flow from that retrofit positioning:
- Tapered profile — the Springfield 36 measures 35-3/4" wide at the front but tapers to 25-5/16" at the back, designed to fit standard masonry fireplace cavities that narrow toward the smoke chamber
- Modulating burner technology — 18,000–35,000 BTU/hr range with continuous adjustment, rather than the fixed single-stage burners typical of new-construction units. The Komfort Kontrol remote modulates output to maintain your set temperature precisely.
- Class-leading efficiency — up to 79.5% steady state efficiency. Significantly higher than most direct-vent gas fireplaces, including Kozy Heat's own Nordik series (70-75%). The modulating burner is a big part of why.
Standard features included with the Springfield 36:
- Komfort Kontrol Remote — Kozy Heat's proprietary programmable thermostat remote control that modulates the burner output to maintain precise room temperature, not just on/off operation
- Ceramic glass — withstands higher operating temperatures than tempered glass; preserves clarity over years of heat cycling
- Front screen — standard arched design (with optional rectangular format available)
- Generous viewing area — 29-5/8" wide × 21-13/16" high for a strong visual presence within the existing fireplace opening

Kozy Heat Gas Fireplace FAQs
What makes Kozy Heat gas fireplaces different from wood fireplaces?
Gas fireplaces offer easier operation, less mess, and more consistent control than a traditional wood-burning fireplace. There is no wood hauling, ash cleanup, or manual fire starting.
What is a direct vent gas fireplace?
A direct vent fireplace draws combustion air from outside and vents exhaust outdoors. This makes it a popular choice for modern installations.
Can I install a Kozy Heat gas fireplace in a room without a chimney?
Often, yes. Many direct vent gas fireplaces can be installed without a masonry chimney, but installation depends on vent routing, clearances, local code, and the selected model.
Are Kozy Heat gas fireplaces for heat or decoration?
Both. Many homeowners choose them for supplemental heat, while others use them as a design centerpiece with realistic flames and decorative media.
Can I choose between traditional and modern styles?
Yes. Kozy Heat offers traditional log-style fireplaces as well as modern linear and contemporary designs.
Should I choose a gas fireplace or gas insert?
Choose a gas insert if you already have an existing wood-burning fireplace you want to convert. Choose a gas fireplace if you are building a new fireplace location or replacing a full fireplace system.
