Propane or butane, which gas should I choose for my professional heating?

The choice between propane and butane primarily depends on two decisive criteria: the outdoor operating temperature and the storage location of your cylinders.

Propane gas is the professional's choice par excellence for outdoor and winter use. Its boiling point of -44°C allows it to function even in very cold weather, unlike butane which freezes at 0°C. This means that in the middle of winter on an outdoor construction site, only propane will reliably supply your heating.

Essential regulatory point: propane cylinders must be stored outdoors due to their higher pressure (7 bars versus 2.5 bars for butane). This safety requirement strictly prohibits their presence in enclosed premises, even temporarily.

Butane gas is suitable for well-ventilated indoor applications when the ambient temperature remains above 0°C. It can be stored indoors (in a ventilated area, away from any heat source), which facilitates its use for a workshop, a garage, or a construction site bungalow heated occasionally in mid-season.

In practice for professionals: systematically opt for propane for construction sites, as it guarantees uninterrupted operation regardless of the weather. Reserve butane for semi-protected spaces used only in mild weather (autumn, spring).

Why does my room need to be ventilated when using a gas heater?

Ventilation is not just a recommendation but a vital safety obligation linked to the operating principle of mobile gas heaters.

Understanding direct combustion:

Our gas heaters use direct combustion, meaning the burner directly heats the air, which is then blown into your workspace. This technology offers exceptional efficiency close to 100% (all gas energy is converted into heat), but it implies that combustion gases (mainly CO₂ and water vapor) are simultaneously diffused with the hot air into the room.

The two major risks without ventilation:

  1. Oxygen depletion : combustion consumes ambient air oxygen. Without renewal, the O₂ level gradually drops, leading to breathing difficulties.
  2. CO₂ accumulation and CO risk : carbon dioxide accumulates, and in case of incomplete combustion (lack of oxygen), deadly carbon monoxide (CO) can form.

Required ventilation in practice:

  • Outdoor or semi-open construction sites : sufficient natural ventilation (openings, airflow)
  • Enclosed premises : mandatory mechanical ventilation with minimum flow rate or permanent openings depending on volume
  • Confined spaces : gas heating is strictly prohibited → use electric heaters

Good professional practice : systematically install a CO detector in areas where you use gas heating indoors. It's your life insurance for less than €30.
