- 100% clean, dry, fume-free heating
- Dual voltage (110V / 240V) compatibility
- 85kW heating power (290,000 BTU/hr)
- Fuel-efficient with 105L tank capacity
- Supplied with trolley wheels for easy positioning
The 85kW Indirect Diesel Heater is a powerful, efficient heating solution designed for safe use in enclosed spaces where ventilation is restricted. It delivers 100% clean, dry, and fume-free warm air, making it ideal for marquees, event spaces, warehouses, workshops, and construction sites.
Unlike direct heaters, indirect diesel heaters operate outside the heated space, with exhaust gases vented safely through a vertical flue. Only clean, filtered warm air is pushed inside via flexible ducting, making it safe for occupied environments.
This model features dual voltage compatibility (110V / 240V) and offers optional analog or digital thermostat controls for precise temperature regulation. With an air displacement of 3,300 m³/h, it quickly heats large spaces while remaining efficient with a fuel consumption rate of 8.1L/hour and a large 105L fuel tank for extended runtime.
Built for practicality, it includes trolley wheels for mobility, an IP44 rating for durability, and optional extras like ducting, exhaust extensions, and rain covers to suit different site requirements.
Each piece of machinery equipment is delivered/ collected by our trained Errigal Plant Hire experts, who will load and unload plant safely from our lorries & vans onto your site.
Once we have the equipment delivered to you, a familiarisation handover will take place to make sure your operatives are aware of the machines basic functions and any safety issues.
This service is also standard practice in our depots where trained staff will demonstrate any hired machine at point of collection.
It’s our priority to make sure you get the job at hand done efficiently, and with the upmost safety of your operatives in mind.
When hiring any piece of quality equipment from Errigal Plant Hire you can be safe in the knowledge that it has been checked and tested by one of our technicians. The equipment will be started and run before your hire to ensure that the machine arrives on site in perfect working order. A member of our team will run the machine demonstrating all it’s functions and safety features before each hire, although we do advise that all customers read the manufacturers operating instructions before use.
