Which System Is Best

Heat Extermination Is 100% Effective!

Heat Treatment Systems and Equipment Compared

You will encounter conflicting information on the internet and also from competing companies claiming the usual stuff – their system is the best, and the one and only and the other guy is of course no good or dangerous or perhaps something vaguely indeterminate and nasty. This page offers actual explanations of the different heat treatment systems out there so that you can decide for yourself. If you have better things to do the truth is that each heat treatment system can be used safely and effectively so if you are comfortable with the company and you trust them, the system they use matters less than how they use it.

Electrical Systems – These are the most common with at least 6 different manufacturers offering bed bug specific heaters, all of which work. Power for the heaters is typically generated outside by a diesel fueled generator, cabling is run into the building and distributes the power to the heaters, which are placed inside the space to be heated. Some models of heater can also be powered off of building power.  Cimex has both heat systems and can heat above 135 degrees when required.  Some electrical systems shut off at 135 degrees.  Cimex has found that there are times when temperatures need to go higher. These systems allow heat treatments in high rise towers as cable is relatively easy to run up multiple floors, and some of them come as a complete start up kit with everything you need. Drawbacks of electrical systems are that the heaters are often underpowered, the systems are not scalable (you cannot do a large house or multiple apartment units at the same time), and the industry leading trailer package that most people buy is quite expensive and therefore keeps costs to clients quite high as well. Cimex Technologies has a custom designed electrical heating system which allows us to do heat treatments anywhere in high rise tower.

Forced Air Systems – these come in several forms, direct and indirect fired, fueled by either diesel or propane.

Indirect Fired – In this scenario the heater is parked outside and clean, dry, hot air is pumped into the space to be heated with ducting running from the heater. The exhaust fumes from the combustion of the fuel stay outside just as they do with electrical systems. The benefits of these systems is that they generate vastly more heat than electrical systems and they are highly scalable – large homes and multiple apartment units can be done all in the same day and therefore treatment times and costs are kept down. The drawback of this system is that they are only useful on buildings 3 floors in height or lower as the hot air cannot be pumped higher. At Cimex Technologies we use indirect fired diesel fueled systems because they are efficient and economical and highly scalable (and we use our electrical system for
the 4th floor or higher).

Direct Fired – These heaters are also parked outside and the hot air is run in through ducting. The drawback of these systems is that the particles of combustion (the exhaust) are also pumped inside the heated space. When propane is used as the fuel a significant amount of moisture is also pumped inside. These issues can be dealt with if the company is diligent and knows what it is doing. This is a very common method of remediation in the US and it has the longest track record of use for pest management (having been used safely for many years against food pests in grain silo’s and commercial food processing facilities, and against termites in the Southern US). This method is not used by Assured Thermal Solutions. Most negative comments coming from companies that only sell or use electrical systems are typically aimed at direct fired propane fueled systems.

The highest risk method which we do not use or endorse is the use of construction style propane fueled direct fired heaters being placed inside the space to be heated. This has resulted in several fires in the United States (and one in Edmonton causing several million dollars damage).

Hydronic (Glycol) Systems – In this scenario diesel is burned to heat a tank of glycol which is then pumped through high pressure hoses in to the building. The hot glycol is run through heat exchangers (the heaters) which are parked inside the rooms to be heated. The glycol is then recirculated back outside to the tank to be re-heated and pumped back inside. These systems are very effective and have been pioneered in Winnipeg, Manitoba. Drawbacks of these systems are that the equipment is very expensive and hard to scale up (additional pumps and hoses are needed to go above three stories). At this point no one in our industry offers this system to our knowledge.

At Cimex Technologies we know our industry, the various systems and how they work and we can bring whatever system is most appropriate to solve your bed bug problem. We also aim to educate and inform in everything we do to help people be comfortable in their choices and make the best decision possible.
