Choosing the right fireplace insert is the key to efficient heating, firewood savings, and safety. Many buyers, when choosing a fireplace for their home or cottage, make common mistakes that later come at a high cost. In this article, we’ll cover the top three mistakes when purchasing a fireplace insert and explain how to avoid them. We’ll also focus on SAVEN steel fireplace inserts — a modern solution for comfortable home heating.
1. Choosing an insert without considering the heating area
One of the most frequent mistakes is buying a fireplace insert without considering the area to be heated. This leads either to overheating the room or insufficient warmth, where the fireplace operates at its limit.
Why is this important?
Each insert has its own heat output, designed for a certain area. If you choose an insert “by eye,” you may not only lose comfort but also shorten the lifespan of the unit.
How to avoid this mistake:
Calculate the required heat output using the formula: 1 kW per 10 m² for a standard insulated house.
Consider the quality of insulation, number of windows, and ceiling height.
Choose SAVEN steel fireplace inserts based on area — the product range includes models with 14, 17, and more kW.
2. Incorrect selection of ventilation grilles
Another critical mistake is ignoring or incorrectly installing ventilation grilles for distributing warm air. Without them, the fireplace cannot effectively release heat, and the cladding may overheat.
Why are ventilation grilles needed?
They ensure natural or forced convection of hot air from the fireplace cladding into the room. This not only improves efficiency but also increases the fireplace efficiency (efficiency ratio).
Common mistakes:
- Grilles that are too small.
- Incorrect placement (too low or too high).
- No exhaust grilles at all.
How to do it right:
- Use ventilation grilles for fireplaces made of heat-resistant materials.
- Place supply grilles at the bottom, exhaust grilles at the top.
- Choose the grille size according to the power of the insert: the more powerful the insert, the larger the total area of openings should be.
SAVEN steel fireplace inserts pair perfectly with air distribution systems — be sure to consult a specialist when selecting grilles.
3. Incorrect flue diameter
The chimney flue acts as the "lungs" of the fireplace. Choosing the wrong diameter may lead to poor draft, smoke leakage, excessive condensation, and even the risk of carbon monoxide poisoning.
Main problems caused by an incorrect flue:
- Smoke returns into the room.
- The fireplace goes out after ignition.
- Excessive soot buildup occurs.
How to avoid this mistake:
- Always select the flue diameter according to the insert’s technical specifications.
- For most SAVEN steel fireplace inserts, the recommended diameter is 180 or 200 mm, depending on the model.
- Avoid long horizontal segments — they reduce draft.
- Use certified modular flue systems made of stainless steel or ceramic.
How to avoid mistakes and make the right choice
To make your fireplace a reliable source of warmth, it’s important to choose a quality fireplace insert, calculate its heat output properly, ensure proper ventilation, and install a professional flue system.
Avoid common mistakes:
- Failing to consider the heating area.
- Neglecting ventilation grilles.
- Cutting costs on a proper chimney system.
By choosing SAVEN steel fireplace inserts, you get:
- High efficiency (up to 80%).
- Durable steel construction up to 4 mm thick.
- A wide selection of models for various needs.
