Gas Fireplaces

Gas Fireplaces

In the Killingworth, CT & Madison, CT Areas

Gas fireplaces provide an efficient, low-maintenance way to bring heat and ambiance to your home without the mess of a traditional wood-burning hearth. They operate on either natural gas or liquid propane and can be controlled instantly with the push of a button, a remote, or even a smartphone app. Depending on your home's setup and architectural needs, models generally fall into three main installation types: direct-vent systems, vent-free units, or fireplace inserts.

Key Benefits

  • Zone Heating Efficiency: They allow you to warm up the specific room you are using rather than running a central furnace for the whole house.
  • Constant Operation: Models equipped with standing pilots or electronic ignitions with battery backups will continue to provide critical heat during winter power outages.
  • Design Versatility: Available in classic rustic brick profiles with high-definition logs, multi-sided see-through divider models, or ultra-modern linear glass styles.

How to Choose a Gas Fireplace

Choosing a gas fireplace involves balancing venting type, heating capacity (BTUs), and aesthetic style. First, decide if you need a built-in unit (for new construction/renovations), an insert (to retrofit an existing masonry fireplace), or a freestanding stove, ensuring the fuel type matches your home.

1. Choose Your Venting Type


Your home's setup will dictate how the fireplace exhausts:


  • Direct-Vent: The most popular and efficient choice. It uses a dual-pipe system to pull outside air for combustion and exhaust byproducts outdoors. Excellent for indoor air quality.
  • Vent-Free (Ventless): Highly efficient since all heat stays in the room, and no chimney is needed. However, they emit moisture and require an oxygen depletion sensor. Note: These are prohibited in some states and cities, so check local building codes.
  • B-Vent (Natural Draft): Uses existing chimneys but draws air from inside the house. They are less efficient but offer a classic, traditional flame.

2. Determine Heat Output (BTUs)


The heat output of a gas fireplace is measured in BTUs (British Thermal Units). You'll need to match the BTUs to the square footage of your room to avoid overheating.


  • A general rule of thumb is 20 to 40 BTUs per square foot.
  • For a 200 sq. ft. bedroom, you might need a small 10,000–15,000 BTU unit, while a large 500 sq. ft. living area may require 30,000+ BTUs.
  • Pay attention to the AFUE rating (Annual Fuel Utilization Efficiency). Aim for models between 70% and 85% for optimal heating performance.

3. Pick Your Style & Fire Media


Gas fireplaces offer massive aesthetic flexibility.


  • Traditional: Features highly realistic ceramic logs that mimic a classic wood-burning fire.
  • Contemporary / Linear: Wide, horizontal windows with fire glass, river rocks, or minimalist burners suited for modern homes.
  • Firebox Styles: Available in single-sided, see-through, or three-sided (peninsula) designs to act as a room divider.

4. Select Key Features & Controls


Modern gas fireplaces come with several upgrades:


  • Remote controls & Thermostats: Allows you to adjust flame height and fan speed from your couch.
  • Blower Fans: Helps circulate warm air throughout the room rather than just radiating heat directly in front of the unit.
  • Battery Backup: Ensures the fireplace can still produce heat during a winter power outage.
