Essential Fleet Vehicle Heating Components for the Winter

As winter looms nearer, the temperatures in Canada begin to drop. Canadians know how brutal winters can be, and these sub-zero ratings make it an issue to move around and conduct work. Working heaters are important to include in your yearly checklist as part of a heating, ventilation, and air conditioning (HVAC) system inspection to ensure the comfort and safety each winter season. 

In the trucking industry, business goes on, as usual, to deliver goods and services to people tirelessly. The issue here is that HVAC systems are only really meant to keep the vehicles heated and warm while running. When truckers have to stop for the night, it can be very uncomfortable to get a good rest while the temperatures are freezing. This is where fleet vehicle services that offer heavy-duty vehicle heating come into play. 

HVAC Technologies for Trucking Fleets

In a truck’s cabin, auxiliary heaters can be fit to promote better idle management of temperatures. There are various types of heaters and HVAC components that all play into creating a comfortable interior environment for truck drivers on the long haul. Here are some of the most efficient auxiliary heating systems that can make your fleet drivers have safer and more comfortable journeys:

1. Water to Air Heaters (WTA)

These heaters use diesel to heat the engine’s cooling water and are pumped in a short or long circulation depending on the temperatures. Lower water temperatures flow into a shorter circulation that goes into the WTA and the HVAC system. 

Higher temperatures of the water go through a more extended circulation that includes the engine. This system reduces the emissions and engine wear due to the already warmed-up state. The ACC device then controls cabin temperatures easily.

2. Air to Air Heater (ATA)

ATA systems function similarly to WTA ones but heat air instead of water. Thanks to a fan that blows air into the ATA from the cabin, the device heats it then leads it back to the cabin. This type of heater controls the cabin temperatures and disengages the ACC control when it is running. WTA is never installed in a vehicle that has an ATA, and vice versa. 

3. Ventilation Systems (HVAC)

HVAC systems suck in air from the outside from the front of a vehicle. This air then moves through an evaporator and a heat exchanger induced by speed or forced by a fan. Recirculating the cabin’s air is also an option to keep the consistency of air within. An HVAC system reduces the heat-up time of cabins during frigid days. HVAC ventilation systems are commonly used and are present in all vehicles, both large and small, as a very efficient and effective heating and cooling system. 

4. Heat Exchangers

Heat exchangers pass heated water from the engine into a circuit that gives off warmth. The WTA can also utilize cooling water for heating, as it passes air through the heat exchanger to heat it, subsequently coursing it out into the cabin. These systems run at a constant temperature of 70 to 80 degrees during a warm and running engine. The rest of the cooling water and heat exchange flows are controlled by a water valve for proper temperature control. 


Heating is essential in the winter, whether you find yourself at home or in a vehicle. Feeling the sharp temperature drops from outside is quite painful and can cause mass discomfort, which can be dangerous for truck drivers going on long haul drives. Keep your fleet vehicle services safe through investing properly into good heating and cooling systems for the interior cabins.
