JCB’s new optional automatic heater system warms backhoe cabs and engines before operators arrive for work

JCB backhoe operators are in for some heart-warming news as the first icy blast of winter strikes. With cold temperatures throughout much of North America, the company has made a new heater system available on its iconic backhoe loaders that automatically heats the cab and engine before the operator arrives for work in the morning.

The device means the machine now takes much less time to reach operating temperature in cold weather and is ready to start its daily shift much faster, boosting productivity for owners and operators.

“This is another fantastic innovation on JCB’s backhoe loaders that will allow operators to simply get in and drive without having to defrost windshields or warm up the engine,” said Tim Burnhope, JCB’s chief innovation and growth officer. “As well as providing greater operator comfort, the new system will cut downtime and boost productivity.”

Available as an option on JCB’s 3CX and 4CX backhoe loaders, the system can be activated using a 24-hour timer with up to three pre-set start times or manually through a switch in the cab. The heater can also be used manually throughout the day when the machine is not in use, maintaining a comfortable working environment. It works by using a water heater that is integrated into the engine’s coolant circuit.

The water heater unit automatically runs a safety check before heating, prior to starting an integrated diesel-fueled burner.  Atomized fuel is sprayed into the combustion chamber and ignited with a high-tension spark. The hot combustion gases flow through a heat exchanger, which transfers the heat to the engine coolant system. This thermal energy is forwarded to the cab through the machine’s ventilation outlets, with residual warmth remaining in the engine.

As the heater is electronically and thermostatically controlled, it works intermittently, only burning for the amount of time required to reach the desired temperature. Furthermore it only consumes a 0.071-0.163 gallons of fuel per hour, making it a low-cost option. A self-diagnostic function ensures trouble-free operation.

The heater system is much more than simply a comfort option, however. It also removes the requirement for an engine block heater in colder climates and extends engine life by reducing engine cold starts.  As the heater runs off the machine’s own fuel supply, there is no need for additional tanks or storage. There is also no need for an external power supply as with an electric block heating system, so the machine can be left in remote areas overnight.
