Gas Heaters

About Gas Heaters

Gas heaters are powerful portable heating solutions that deliver reliable warmth in workshops, construction sites, warehouses, and outdoor spaces where electric heating isn't practical. These propane-powered units provide exceptional heating capacity with outputs typically ranging from 10kW to 40kW, making them essential equipment for tradespeople working through Britain's colder months. MyToolShed.co.uk stocks trusted brands including Sealey and Draper, offering both radiant space heaters with ceramic plaques and high-output jet force heaters for larger commercial spaces.

Unlike mains-powered alternatives, propane gas heaters operate independently of 240v electricity, generating instant heat without lengthy warm-up periods. Most models feature piezo ignition for easy starting, adjustable heat settings for precise control, and safety features including flame failure devices and tip-over switches. This makes them remarkably cost-effective for heating larger areas and invaluable for sites without fixed electrical infrastructure.

Applications

• Construction and building sites – heating spaces before power is connected or in remote locations
• Groundworks contractors – preventing materials from freezing and maintaining comfortable working conditions
• Plasterers and decorators – accelerating drying times and maintaining optimal temperatures for materials
• Mechanics and vehicle technicians – warming unheated garages, workshops, and mobile repair situations
• Agricultural workers – heating barns, livestock shelters, and outbuildings
• Event organisers – providing temporary heating for marquees, outdoor functions, and commercial events
• Warehouse and logistics facilities – supplementing heating in large storage areas and loading bays
• Horticultural businesses – protecting plants in polytunnels and covered growing areas
• DIY enthusiasts – tackling renovation projects in unheated spaces during winter months

Choosing The Right Gas Heaters

Heat Output Requirements: Calculate your space in cubic metres to determine the kW rating needed. As a general rule, you'll need approximately 0.03kW per cubic metre for well-insulated spaces, or up to 0.06kW per cubic metre for poorly insulated areas. A 15kW heater typically covers 150-200m² of floor space in standard workshops.

Heater Type: Radiant space heaters with ceramic plaques provide gentle warmth ideal for smaller workshops where people remain relatively stationary. Jet force heaters use powerful fans to rapidly circulate heated air throughout larger spaces, making them better suited to warehouses and construction sites requiring quick temperature increases.

Portability: Bottle-mounted heaters attach directly to propane cylinders for maximum portability between jobs, whilst trolley-mounted units with wheels offer easier movement around spacious sites with added stability.

Safety Features: MyToolShed.co.uk recommends models with flame failure devices, tip-over switches, and adequate ventilation requirements clearly specified. All propane heaters consume oxygen and produce combustion gases, so they must only be used in well-ventilated spaces.

Safety Information

Ventilation is Critical: Never use propane heaters in poorly ventilated or confined spaces. Ensure adequate ventilation by keeping doors, windows, or vents open during operation. The HSE recommends a minimum of two permanent ventilation openings when using gas heaters indoors.

Clearance and Storage: Maintain at least one metre clearance from combustible materials. Always store propane cylinders upright and secure them to prevent tipping. Check connections regularly for leaks using soapy water, and never use damaged cylinders.

Carbon Monoxide Awareness: Install carbon monoxide detectors in any enclosed space where gas heaters operate. Never leave operating heaters unattended, and allow them to cool completely before moving or storing.

Frequently Asked Questions

Can I use a gas heater indoors?

Yes, but only with adequate ventilation. Propane heaters must never be used in confined areas without proper airflow. Ensure doors, windows, or permanent ventilation openings provide sufficient fresh air circulation, and consider using a carbon monoxide detector for additional safety monitoring.

How long will a gas cylinder last with my heater?

This depends on your heater's output and heat setting. A typical 15kW heater running on maximum consumes approximately 1.09kg of propane per hour, meaning a standard 13kg cylinder would last roughly 12 hours of continuous use. Lower settings significantly extend operating time.

What's the difference between radiant and jet force heaters?

Radiant space heaters emit infrared warmth that heats objects and people directly – they're quieter and ideal for smaller spaces. Jet force heaters use fans to blow air across a heat exchanger, rapidly distributing warmth throughout larger areas with high ceilings where radiant heat alone would be insufficient.
