Need powerful heat without fumes? Our Indirect Diesel Blow Heater for hire from A-Z Hire delivers clean, dry, fume-free warm air, making it the correct heating solution for enclosed or poorly ventilated spaces.
Unlike direct-fired heaters, this indirect heater safely expels combustion gases outside via a flue while only clean heated air is blown into the workspace. That makes it ideal for sites where people are working, materials are sensitive, or air quality matters.
A-Z Hire is a trusted name in tool hire in Dublin, supplying professional heating equipment to construction, restoration, events, and industrial customers across the city.
Indirect combustion ensures no exhaust fumes enter the heated area. This makes the heater suitable for:
Warehouses
Workshops
Marquees and event tents
Temporary structures
Indoor construction and fit-out projects
The heater produces dry heat, helping to reduce condensation and support drying applications such as plastering, painting, and flood restoration.
Mounted on a robust trolley with large wheels, the unit is easy to move around site. Optional flexible ducting allows heat to be directed exactly where it’s needed.

Indirect heaters are highly efficient and provide 100% clean, dry and fume free air. They are best used where there is limited ventilation in the space you are looking to heat such as warehouses, exhibition halls and marquees to name but a few.
The Indirect heater is placed outside where the exhaust fumes are vented through a vertical exhaust pipe into the open air.
