Examining Portable Indirect Oil Fired Heaters

This is a comprehensive breakdown of portable indirect oil-fired heaters for marquees

Portable indirect oil-fired heaters are highly regarded as THE marquee heating solution among industry professionals.

Because of the unique situational constraints of a marquee based event, coupled with the physical challenges involved in heating poorly insulated outdoor, temporary spaces - this kind of job calls for a powerful, yet clean burning, mobile heating solution.

Indirect oil-fired heaters are just the answer to this problem.

Manufacturers of this type of product can be found with HQs here in the UK and abroad, often with sterling history and longevity in this market, leveraging on 'being at it the longest' to innovate the most advantageous engineering features into their product.

Whilst on the surface of it, a heater to the unlearned might just be a heater. And that indeed it is.

But as you will know, when it comes to the frantic pace of the event hire industry, every penny, second and customer counts. This is exactly where getting your equipment investment right will be worth the time and effort spent to get it right.

Remembering also that small gains on efficiency or effectiveness won't stay small for long in a high volume business like marquee hire, where each incremental benefit only mounts up cumulatively over time to add more profit, one way or another back into your pocket.

Our marketing background tells us, the best place to start with a product review is: 'the benefits...of portable indirect oil-fired heaters'

Indirect oil-fired heaters are a staple solution of choice for many users across multiple industries, worldwide. Whilst our focus on this blog is marquee event tents, we begin by making it clear that the use of these versatile heating products goes far beyond heating just tents (although it's application in this area is indeed, filled with benefits).

Essentially, indirect oil-fired heaters are industrial space heaters used for enclosed environments, with user benefits as follows:

  1. Produces 100% clean, zero-emission hot air outputOutline Indirect Oil Fired Heater
  2. Dry heat output only, no humidity
  3. Can be located external to the marquee using ducts to pipe in hot air
  4. Positive pressure for moving large volumes of airflow through the marquee
  5. Able to heat large volumes of space with only one heater
  6. Can use safely where ventilation is lacking
  7. Compatible with thermostat
  8. Very mobile
  9. No overheating components
  10. Gauges always make you aware of fuel usage and diagnosed problems
  11. Easy maintenance with snap on components
  12. Use safely at various altitude with adjustable combustion calibration
  13. Quick start-up: plug-in, pour fuel, connect flue, go!
  14. Easy to wheel around - fuel tank designed for optimal centre of gravity when full
  15. Lasts longer with very durable mechanics
  16. Transparent filters for pre-emptive maintenance & cleaning

This by no means is an exhaustive list, but we hope it paints the picture of what you should expect to get out of an indirect oil-fired heater.

Now for the indirect oil-fired heater technical specifications which underpin all the fine benefits above

Whilst not all technical specifications are user-friendly, giving useful inference to the practical advantages of using equipment, there are some specifications which do give good supporting, illustrative detail.

These specifications, if not published uniformly by every manufacturer, can be requested specifically should you need more information (doen't be afraid to ask the manufacturers):Anatomy of Indirect Oil Fired Heater

  • Heat output (BTU/h, Kcal/h)
    • this gives the direct measurable power output
  • Air velocity (m/s)
    • the speed of air being pumped into the marquee
  • Throw (metres)
    • the reach of the hot stream emitted from the machine
  • Pump pressure (psi - pounds per sq. inch)
    • force generated by the pump to push air
  • Sound level (dBa)
    • noise the machine makes whilst running
  • Electricity supply (volts)
    • electric power needed to operate
  • Tank capacity (l)
    • the full tank statistics
  • Weight (kg)
    • the weight of the entire machine
  • Fuel consumption (L/h)
    • amount of fuel used per hour to operate
  • Heated airflow (m3/h)
    • volume of air moving from the heater into the marquee within an hour
  • Max pressure (pascals)
    • pressure issued by the equipment
  • Outlet diameter (mm)
    • opening for releasing hot air
  • Dimensions (height, length & width)
    • size of the equipment
  • Weight (kg)
    • the load you'll have to carry around
  • Power of fan motor (rpm)
    • the output of the fan motor for drawing in cool air and pushing out hot air
  • Maximum air temperature (degrees C)
    • top air temperature released from nozzle
  • Maximum fuel consumption (l/h)
    • a useful measure of how much fuel is used per hour

This listed information combined with the benefits above will equip any marquee hire contractor with more than enough of a knowledge base on paper for making accurate performance comparisons among heater units of certain manufacturers.

Like with many a great product, are there any accessories for indirect oil fired heaters?

As the product themselves are made off the shelf with all the built-in functionality you could want, there is very little scope for improvement really. But that's not to say, the manufacturers haven't heard the needs of customers and retrospectively made available some simple bolt-ons to enhance the user experience.

The following are typical accessories offered by manufacturers of indirect oil fired heaters:

Thermostat: allows you to keep a care eye on the ambient room temperature in the marquee, These are usually accurate to +/- 1.5 degree C

Duct hoses: position the heater external to the building and simply pump in the heat via ducts which can be directed into the spaces where the heat is most urgently required.

Diffuser: diffuse the heat throw of the heater to disperse the heat benefit more readily into your marquee space.

Rain cover: when externally using the heater, ensure all the mechanics remain untroubled by rainfall.

How much will a new indirect oil-fired heater cost to buy?

Depending on the size and power output of the machine, such a heater could cost in the region of £350.00 - £1,000.00 brand new.
