There are a number of bunk heater brands on the market today that offer varying amounts of fuel savings, , driver comfort and reduced maintenance costs. Deciding which brand is worth the money can be quite challenging.

When considering a top quality bunk and cargo heater for transport trucks, vans and passenger vehicles like the Espar air and coolant heater, there are several reasons why these auxiliary units are a good investment.

An Espar air and coolant heater designed for bunk and cargo heating works separate from the onboarding heating system of the truck or van. This climate controlled add-on is favored by drivers due to the benefits it delivers: fuel efficiency, driver comfort, and maintenance costs

When you install an Espar air or coolant heater, drivers can benefit from the following.

Enhanced Comfort
Whether you’re driving a truck, van or passenger vehicle, the onboard heater can provide plenty of comfort throughout the travelled miles, This may not be sufficient enough to handle the long and cold layover nights especially during long hauls. Depending on the rest time required, heating the vehicle when stationary can result in additional wear and tear on the vehicle’s mechanical components.

When using an auxiliary air heater for bunk or cargo heating, the auxiliary device works by itself, delivering the same comfort to the sleeping compartment without idling the engine. Drivers can expect the same level of cab and cargo comfort with an auxiliary bunk heater for your truck or van.

Espar coolant heaters also ensure that the engine stays warm when the vehicle is not operational. Providing engine preheating and a smoother start the next morning means less stress on cold engine components and less time warming up the engine before deliveries.

Ensure Fuel Efficiency
The fuel supply of your commercial vehicle will reach its limit if you keep a truck running just for heat alone. When you use an Espar air heater instead, this device pulls from its own supply of fuel. It does this very efficiently and when you add up the number of stops and layovers that a driver can make on long hauls, it can save a lot of money. Espar coolant heaters work with the vehicle’s coolant system to preheat the engine and/or keep it at the optimal temperature when not idling. This reduces cold starts and faster cabin heating on cold days.

Save on Maintenance
In addition to reduced fuel usage, the engine and related components are running less. Drivers save directly on maintenance expenses by reducing engine idling thereby extending the duration between oil changes and the lifespan of components like the air compressors, alternators, belts, hoses, etc. It also reduces the wear and tear of the engine which can result in costly repairs, replacement of parts and costly downtime.


There are many air and coolant heaters on the market today for commercial and passenger heaters. The fuel efficiency, driver comfort and cost savings provided by these auxiliary heaters are unmatched.
