Indoor Fireplaces: How to Add Warmth & Value Before the Next Cold Snap

December 19, 2025

When Wisconsin temperatures drop, the fireplace becomes more than a design feature — it becomes the heart of the home.


If you’ve ever thought about upgrading your current fireplace or adding one to your living space, winter is actually one of the best times to do it. While many homeowners wait until spring to tackle home upgrades, fireplace projects are perfectly suited for cold-weather planning and installation.


At Zillges Landscape, Fireplace & Excavation, we help homeowners across Oshkosh, Neenah, Appleton, and the Fox Valley design and install indoor fireplaces that add warmth, efficiency, and long-term value.



This guide walks you through everything you need to know before your next cold snap hits.


Inside this post


In this guide, you’ll discover:

  • Why winter is ideal for fireplace upgrades
  • Gas vs. wood options for Wisconsin homes
  • Retrofit possibilities for existing homes
  • Efficiency and heating considerations
  • What to expect during installation


By the end, you’ll know whether a fireplace upgrade is the right move — and how to get started.


Step 1: Decide Why You Want a Fireplace


Before choosing fuel type or style, define your main goal.


Are you looking for:

  • Primary heat support during extreme cold?
  • Supplemental warmth for comfort and ambiance?
  • A new design focal point for your living room?
  • Increased home value and resale appeal?


Clear priorities help determine the right installation type and system for your space.


Step 2: Understand Your Installation Options


Many homeowners assume adding a fireplace requires major reconstruction. In reality, modern systems offer flexible solutions.


Common installation types:

Gas Fireplace Inserts

  • Installed into existing masonry openings
  • Highly efficient and low maintenance
  • Clean-burning and convenient


Direct Vent Gas Fireplaces

  • Ideal for homes without existing chimneys
  • Sealed systems that vent through exterior walls
  • Excellent heat control and efficiency


Wood-Burning Fireplaces

  • Traditional look and experience
  • Best for homeowners who love the ritual of real fire


Zillges helps homeowners evaluate which system fits their structure and lifestyle.


Step 3: Compare Gas vs. Wood for Wisconsin Winters


Cold Wisconsin winters demand reliable heat. Here’s how the two main options compare:


Gas fireplaces are often preferred for convenience and efficiency. Wood fireplaces remain popular for homeowners who love tradition and hands-on operation.


Step 4: Consider Design & Placement


A fireplace should complement your home’s layout.


Popular placement ideas:

  • Living room centerpiece
  • Basement finishing projects
  • Open-concept family rooms
  • Indoor-outdoor transition walls
  • Master bedroom feature wall


Modern fireplaces come in linear, traditional, and contemporary designs — allowing seamless integration with almost any style.
