Choosing the Right Commercial Heater: A Guide

When cold weather hits or heating systems breakdown, the pressure is on for businesses to maintain warm and productive environments. Whatever commercial sector you’re in, whether it’s events, hospitality, or anything in-between, Andrews Heat for Hire has the perfect solution for your unique needs.

With decades of experience and the widest range of heater rentals in the UK, we’ve got exactly what you need. In this guide, we explore the key differences between indirect, direct, and electric heaters – and how to choose the right one for your needs.

Indirect Fired Heaters: Clean and Powerful Heat for Enclosed Spaces

Indirect fired heaters are perfect for environments where people are present, and ventilation is limited. These units work by heating air via a sealed combustion chamber and expelling exhaust gases outside via a flue. This makes indirect fired heaters a safe choice for enclosed or semi-enclosed spaces like marquees, warehouses, and large-scale events.

With high heat and the ability to duct warm air into the required space, indirect heaters offer fume-free, dry heat, which is a must for temperature-sensitive environments or safety-regulated sites.

Direct Fired Heaters: Instant Heat for Well-Ventilated Spaces

Direct fired heaters are powerful and efficient, generating heat by burning fuel directly into the airflow. They’re best suited for open and well-ventilated spaces like agricultural buildings, loading bays, and workshops. This is because they release combustion by-products, so should never be used in sealed or poorly ventilated areas.

Thanks to their simplicity and fast heating capabilities, direct fired gas heaters, including oil and gas units, are a popular choice for industrial heater hire.

Electric Heaters: Convenient, Fume-Free Heat for Smaller Spaces

If you need portable heater hire for an office, school, shop, or temporary workspace, electric heaters are ideal. They’re clean, silent, and easy to install – simply plug in and go. With no fumes or combustion, these units are perfect for areas where health, comfort, and compliance are key.

Electric heater hire units are also popular during renovations, in care homes, and across the public sector thanks to their safety and convenience.
