What Is the Safe Height to Mount a TV Above an Ethanol Fireplace? Real Temperature Data Tested at 40–100 cm

Why TV Mounting Height Above a Fireplace Matters

Ethanol fireplaces produce genuine, open flames and generate substantial radiant heat. Unlike electric fireplaces, the heat output is real and rises directly upward. Sustained exposure to temperatures above 60 °C can degrade LCD panels, warp TV casings, and void manufacturer warranties - most TV makers specify a maximum ambient operating temperature of 50–60 °C.

To give homeowners and designers a clear, data-driven answer, we conducted a controlled measurement test using a 120 cm smart ethanol fireplace, recording temperatures at four heights directly above the flame: 40 cm, 60 cm, 80 cm, and 100 cm.

 

 

Test Setup and Methodology

The fireplace was operated in two modes commonly used in real living environments:

• Flame Level 1–3 (low–medium intensity): suitable for ambient warmth and ambiance
• Flame Level 4–5 (high intensity): maximum heating output

Temperatures were measured at steady state using a calibrated probe positioned at each height. The images below show each measurement configuration.

The table below summarizes all measurements. Each cell shows the observed temperature range at steady state for that distance and flame level combination.

Raw measurement data - temperature ranges recorded at each height and flame level

 

Flame Level	40 cm above	60 cm above	80 cm above	100 cm above
1–3 (Low–Medium)	75–83 °C	55–63 °C	46–52 °C	42–49 °C
4–5 (High)	83–91 °C	54–65 °C	53–58 °C	48–54 °C

 

Analysis: What the Numbers Tell Us

The results reveal a sharp temperature gradient across distances:

At 40 cm, even at low flame levels, temperatures reached 75–91 °C - well beyond the safe operating range for any consumer television. Mounting a TV this close is not recommended under any circumstances.

At 60 cm, temperatures ranged from 54–65 °C. While this approaches the upper limit of many TV specifications at high flame settings, it remains the practical sweet spot for most real-world installations where the fireplace is not operated at maximum intensity continuously.

At 80 cm, heat drops to 46–58 °C across both flame levels. This is within the safer zone, particularly for flame levels 1–3.

At 100 cm, temperatures stay at 42–54 °C - the safest measured range - though this height may create an ergonomically awkward viewing angle in many living room layouts.

Our Recommendation: 60 cm Minimum for Most Installations

Based on the measured data, we recommend a minimum clearance of 60 cm between the top of the ethanol fireplace and the bottom edge of the TV, subject to the following conditions:

The fireplace should not be operated at flame level 4–5 for extended periods when TV is in use

The room should have reasonable ventilation so heat is not trapped against the wall

Users should consult their TV manufacturer's ambient temperature specification before installation

If you regularly use your fireplace at full power, or if your TV model has a rated maximum ambient temperature below 50 °C, consider mounting at 80 cm or higher for additional safety margin.
