Portable Gas Heaters For Industrial and Commercial Properties
At National Heater Shops, we offer a wide selection of portable gas heaters and LPG heaters for industrial and commercial purposes. These heaters are to only be operated outside or in well-ventilated areas as they produce fumes that can potentially be dangerous.
Portable gas heaters provide a powerful and cost-effective solution for industrial, commercial and professional environments. Designed to deliver fast, efficient heat where and when it is needed, these heaters are widely used across construction sites, warehouses, workshops, factories, agricultural facilities, event spaces and other large, well-ventilated areas.
Gas space heaters burn propane or butane gas that enters the appliance through an intake duct and is lit by pilot light. Unlike electric heaters, these units create waste fumes which enter the environment, meaning they can only be safely used in large, well-ventilated areas.
We provide a wide selection of portable gas heaters from trusted brands such as Arcotherm, Sealey, SIP and REMKO amongst others that can be trusted for long-term performance and operational reliability.
LPG Gas Space Heaters
Liquified petroleum gas (LPG) heaters produce radiant heat. They are perfect for wide open working spaces such as warehouses, workshops, garages and more. These heaters are compact and suitable for emergency and temporary heating when and where it is needed. Portable gas heaters are easy to connect to gas canisters and offer almost instant heat. Additionally, they are also easy to ignite using safe, straightforward controls.
Gas Space Heaters For Efficient Area Heating
Gas space heaters are a popular choice when it comes to heating large or partially enclosed spaces quickly and effectively. They use propane or other compatible gas fuels, such as butane. Despite only being usable in well ventilated areas, there are still many benefits to these units, including:
Portability
Rapid heat up times
High heat output
Suitable for temporary operation
Cost effectiveness
For units that can be used in enclosed spaces, see our collection of electric fan heaters. For gas units that can be safely operated in enclosed spaces, check out our selection of indirect oil fired space heaters instead.

Portable Gas Heater FAQs
What are portable gas heaters used for?
Portable gas heaters are commonly used to provide temporary or supplementary heating in industrial, commercial, and construction environments. They are ideal for warehouses, workshops, factories, agricultural buildings such as barns, event spaces and building sites where fixed heating may be unavailable or impractical.
What is the difference between a gas space heater and an infrared gas heater?
Gas space heaters operate by warming the surrounding air to raise the overall temperature of a space, whereas infrared gas heaters work by transferring warmth directly to people, objects and surfaces using radiant heat. You can browse our full selection of gas and diesel infrared heaters here.
Which fuel types do portable gas heaters use?
Most portable gas heaters operate using propane, LPG, or other compatible gas fuels. Fuel compatibility varies between models, so it is important to check the manufacturer’s specifications before use.
