Whether you’re a newbie or not, deciding between direct and indirect-fire heaters can be hard. We’ve discussed everything that would help you choose the right one.
Between direct and indirect options, direct heaters burn fuel the most efficiently. If you’re going to be spending a lot on fuel, you don’t have to worry about it going to waste; 100% of it will be burned.
Although direct fire options burn 100% of their fuel, there is a major problem with them – they produce carbon monoxide. You’re advised to place them outdoors or in a well-ventilated space.
Be mindful of the items surrounding the heater. You should make note whether the materials in the area are flammable or not. Having them close to the hot exhaust fumes could result in a dangerous situation. Some materials may be sensitive, so they would degrade in the presence of the emissions too.
Thermostats would tell you how hot the heat produced would be. Between direct and indirect heaters, you’d be able to find thermostats in almost all models. Of course, how old of a rental you’d be getting would affect the presence of the thermostat.
The newest options have thermostats that are very sensitive and easy to read.
How much are you willing to pay? You may need a large heater for a long period of time. There is a possibility you’d be hit with a massive bill. What would help you save would be deciding between direct and indirect heaters.
Due to the clean air indirect options produce, they are the priciest. They can cost up to 3 times more than direct heat counterparts. Their price is also high due to how convenient they are – you can place them in small spaces, as you don’t have to worry about carbon emissions.
Not only are indirect options pricier to rent, but they cost more to maintain as well.
The availability between the two types is the same. Large names like Aggreko would have an equal selection of both heaters.
Speaking of the type you’d get, know that direct heaters are simpler, so they’re easier to transport and install.
How much heat do you need produced? If you require a lot of heat, you won’t be able to use an indirect heater. Remember that it doesn’t burn 100% of the fuel – you can expect a max of 80% of it being burned.
Let’s say you have a well-ventilated open space to place both types of heaters. Which of the two would be safer? You’d think that direct-fire options would be less-safe; air passes directly through a flame after all. But this isn’t true. There are many safety protocols and measures that manufacturers place.
From the two type heater types, you now know which would be the most worth your time. If you need to heat a large area, a direct-fire option might be needed. It would burn 100% of its fuel. And it would be easier and more affordable to install.
