Understanding the Difference Between Indirect & Direct Heat Could Save Your Bottom Line and Your Building
Direct Heater: Low Upfront Cost, Lots of Problems Down the Road
A typical million btu fired direct heater, for example, creates about 45 lbs. of water every hour. That is the same thing as someone dumping a 5-gallon bucket of water in your building every hour. This is why, when you add direct fired heat as a temporary climate solution in a space, your windows sweat and your ceiling drips. With a direct heater, an exposed flame has air blown through it and directly to where it needs to go. Direct heat is dangerous for humans, and allows too much moisture to be added to the environment.
Not only is direct heat dangerous for employees, and a problem for the building itself, it’s also more expensive than an indirect heater to operate. For example, a business may purchase a 4 MBTUh direct heater for a very low upfront cost. However, only a fraction of the btus would be needed if they recirculated the heat. The low upfront cost is deceptive.
Indirect Heater: A Better, More Cost-Effective Solution
A better option for a temporary climate solution? An indirect heater featuring an enclosed flame.
Indirect heat doesn't have the same problems as direct heat, because the air is processed before it comes into the space. An indirect heater uses dry and clean air from outside, instead of dirty wet air. Indirect is significantly more expensive in the beginning, but safer and less costly in the long run.
The differences in the two types of heaters are crucial for a site manager to examine. Polygon only offers indirect heating, because we care about our customers and want them to have the best heating solution available.

Half the Noise of a Conventional Torpedo Heater
One of the most common complaints about Diesel torpedo heaters is that they are quite loud. In fact, conventional forced air heaters produce about 92 dBA of sound, which exceeds the OSHA threshold for hearing protection. In terms of decibels, it’s like having a motorcycle running in your work area all day.
SilentDrive® heaters, by comparison, reduce this noise pollution by around 10dBA, which amounts to a 50% noise reduction in your work space.
In the field, the difference is clear. You hardly even have to raise your voice to talk around a running SilentDrive® heater, whereas you have to shout to be heard over the drone from a conventional forced air heater.
So What Have We Changed?
The SilentDrive® forced air heater series utilizes our patent pending Dual Fusion technology to directly inject fuel and air for efficient combustion and heat exchange. Gone is the noisy and inefficient fuel pump system that has remained unchanged for over 60 years.
The elegance of SilentDrive® is in the simplicity of its design. Our Dual Fusion technology fixes inefficiency with a “right sized” motor, a quiet blower and a quiet impeller air circulation system. Motor size is reduced, electrical power requirements are reduced, air turbulence is removed, and the heater hums along producing all of the heat you demand at half the noise.
The new maintenance-free electronic fuel pump gets rid of much of the hassle necessary to keep a conventional torpedo heater running smoothly. There is no air pressure to adjust, no air filters to replace, and no rotor gaps to keep set.
Fuel Saving Features
All SilentDrive® Diesel Heaters come equipped with variable heat settings and a built-in thermostat.
These features help to conserve fuel in the field, while also making SilentDrive® heaters extremely versatile for use in a wide variety of settings.
Lower Electricity Costs
By separating the combustion process from the blowing process, SilentDrive® heaters are able to use their electric motors more efficiently. As a result, our measurements indicate that a SilentDrive® heaters use 46% less electricity than an equivalent conventional Torpedo Heater.
Ease of Portability
Ease of portability is very important to our customers. All of our SilentDrive® Construction Heaters come equipped with heavy duty solid wheels which are mounted to a high-grade steel support structure.
Why Choose SilentDrive®?Job site heaters are essentially “productivity boosters.” They make a cold working environment more comfortable for people, and more efficient for equipment.
Like cold temperatures, loud sustained noise also causes discomfort and a loss in productivity. Such noise puts extra strain on the body, and makes it difficult to communicate effectively.
SilentDrive® heaters boost productivity in both ways by generating powerful heat with half the noise.
More comfort, more convenience, more productive. That is why productive people everywhere are using SilentDrive® for space heating.

A new study shows bed bugs are very hard to kill. Here's how to get rid of them—or prevent them from ever moving in.
Two insecticides commonly used to kill bed bugs are becoming less effective against them, according to a study published today in the Journal of Economic Entomology.
In the past 15 years, there has been a resurgence of bed bugs throughout the U.S., and people often struggle to rid their homes of the hardy pests, known for causing itchy red welts.
After the bugs developed resistance against many of the most powerful pesticides, such as DDT, exterminators had been increasingly relying on two chemicals—chlorfenapyr and bifenthrin. But until now, no one had looked at whether bed bugs were developing defenses against these chemicals too, says Ameya D. Gondhalekar, one of the study authors and a research assistant professor at the Center for Urban and Industrial Pest Management at the Department of Entomology at Purdue University.
Find out how to check for bed bugs in a hotel, which includes a video on what to do if you spot bed bugs in your room.
Gondhalekar and his team exposed 10 different groups of bed bugs collected from different parts of the country to each of the chemicals in a glass vial. After several days, they examined how effective the chemicals were at killing the bugs.
While most of the bed bugs were wiped out by the chemicals, three groups continued to thrive after being treated with chlorfenapyr, and five groups were still kicking after being treated with bifenthrin. That means that while some bed bugs will respond to these chemicals, others won't—and it's likely that more and more bugs will become resistant over time.
“This is just more evidence that this pesticide-only approach to controlling bed bugs isn’t really working,” says Consumer Reports’ senior scientist Michael Hansen, Ph.D. “The take-away is that if you want to control these bed bugs, you can’t just spray.”
How to Prevent a Bed Bug InfestationPrevention and vigilance are key to preventing a bed bug problem. “It’s much easier to control them if they are found early, [when there are only a few of them], as opposed to when they grow to number in the hundreds,” says Gondhalekar.
Monitor your home. Bed bugs like to hide in cracks and crevices like walls, luggage, boxes, and clothing, but since they feed on humans while they sleep, they’re most commonly found in beds. If you suspect an infestation, or if you live in an apartment building with a bed bug problem, regularly inspect your bed sheets, mattress (including underneath), and box-spring seams for bugs. They’re flat and oval-shaped, with red or brown bodies, roughly the size of an apple seed. Watch for adults, nymphs, and eggs, as well as exoskeletons (casings that the bugs leave behind when they molt) and dark, rust-colored spots (feces).
Encase your mattress. Enclosing your mattress, pillows, and box spring with a protective cover can block bed bugs from reaching their favorite hiding place.
Be cautious when you travel. Hotel and motel rooms are hotbeds for bed bugs. When checking in, put your luggage in the bathroom, then inspect the bedding. Stow your suitcases on a luggage rack or a hard surface.
When you return home, quarantine your bags. Decontaminate your luggage and clothing by putting your entire suitcase into a large chest freezer (if you have one) for four days, suggests Gondhalekar, before bringing them back into your home. Extreme hot or cold temperatures kills bed bugs. You can also put your clothes in the dryer on a hot setting for 30 minutes, and try steam cleaning your luggage and clothing.
How to Treat a Bed Bug InfestationMinimize its spread. First, notify your landlord if you rent in a building to control its spread to other units. Thoroughly vacuum any infested areas, including carpets and mattresses, and then empty the vacuum bag into a plastic bag, seal it, and throw it in the trash outside. If you can’t get the bed bugs out of your furniture, discard items in a responsible manner. To avoid someone else from salvaging infested furniture or mattreses, rip, remove stuffing, or spray paint with the words “bed bugs.”
Bring on the heat. Heating infested furniture or the entire apartment to a very high temperature—more than 100 degrees, in most cases—will kill bed bugs. Ameritemp Group sells Mosebach BK1-G4 Portable Electric Bed Bug Heater, it's designed in much smaller and lighter enclosures than their competitors, eliminating insect infestation through the use of heat rather than chemicals and toxins.
Use an insecticide alternative. Substances such as diatomaceous earth, boric acid, and silica gel kill bed bugs by damaging their outer coating so they dry out and die. Put these powders into cracks and crevices around your home (being careful not to ingest or inhale them).
Enlist professional help. Not all bed bugs respond the same way to insecticides, so if you have an infestation that you can’t control yourself, a professional can help you determine the correct treatment or insecticide to use.
