Highly portable or fixed options make for a versatile solution. Enquire below and speak to an expert today.


Why choose indirect oil-fired air heaters?

An indirect oil-fired heater is a portable or fixed unit that can generate a large volume of clean, fume-free warm air heating. To do this, these heating systems harness the power of combustible fuels, such as oil and biofuel.

Unlike direct-fired space heaters, these types of systems isolate a flame, preventing it from directly combusting with the flow of air. By relying on a highly efficient heat exchanger to transfer this energy, warm exhaust air is free from unpleasant and unsafe pollutants like CO2.

As a result, indirect oil-fired heating systems can be used safely inside spaces with reduced ventilation, as well as outside areas.

Indirect-fired oil space heaters are robust units suited to a number of roles and scenarios. Some of these include:

  • Keeping remote field hospitals and military camps warm
  • Heating teams within indoor construction sites
  • Warming greenhouses and garages
  • Generating heat for outdoor events and venues

As there are many applications and numerous different types of indirect oil-fired space heaters, determining which unit would be the most effective and cost-efficient in your scenario is key to minimising cost and maximising performance.

Indirect oil-fired air heater: Frequently Asked Questions

What is an indirect oil-fired air heater?

Indirect oil-fired air heaters are highly efficient heating systems that are designed to produce large volumes of warm, fume-free air using combustible fuels such as oil and biofuel.

Available in both fixed and portable variants, this technology is used in many environments, from farms and warehouses, to tents and construction sites.

How does an indirect oil-fired air heater work?

In order to produce clean air, indirect oil-fired heaters burn fuel to create a flame, which is isolated in a combustion chamber. As air is drawn through the machine, a highly efficient heat exchanger transfers this energy, creating warm air without releasing unwanted pollutants.

What is the difference between direct and indirect oil-fired air heaters?

Indirect oil-fired and fuel-fired heaters share many similarities. But there are key differences between each technology.

Firstly, indirect oil-fired heaters use oil and biofuel to deliver their output, whereas fuel-fired systems commonly run on natural gas, propane or diesel.

Additionally, while indirect oil-fired heaters are typically more costly to run than other fuel-fired solutions, oil is often a more readily available fuel on many sites.

Furthermore, fuel-fired systems that run on gas cannot be used underground, as it is colourless and highly flammable. Oil-fired systems, on the other hand, can be safely used in these settings.

What are the benefits of using an indirect oil-fired air heater?

Indirect oil-fired heaters are able to produce large amounts of warm air to keep temperatures regulated safely, inside or out.

These types of solutions are also convenient to operate, as oil is often more readily available than other fuels, and can be used in a broad range of industries and applications.

What are the applications of indirect oil-fired air heaters?

Due to their robust, versatile nature, indirect oil-fired heaters can be used to fulfil tasks in a wide variety of settings, such as:

  • Drying wet construction materials, such as plaster and concrete
  • Heating field hospitals and temporary military shelters safely
  • Keeping garages and warehouses suitably warm

How do I maintain my indirect oil-fired air heater?

A proactive servicing schedule helps keep your indirect oil heaters operating at peak performance throughout their entire operational lifetime.

To do this, revisit the manual regularly, as it will contain directions for keeping your equipment in pristine condition. At a minimum, you should:

  • Routinely check the power supply wire for breaks and damage
  • Clean and replace dirty filters at least once per year
  • Inspect and clean the fuel tank annually ahead of winter
  • Regularly assess core components for any signs of wear

As the European leaders in indirect oil-fired air heaters, we understand how vital maintenance is to the efficacy and safety of your equipment. That is why we have dedicated offices, suppliers and servicing partners focused on providing ongoing support whenever you need.
