How to reduce the cost of owning an engine heater?

For fleet vehicles equipped with small immersion heaters or direct immersion oil heaters, the ability to save money usually depends on the weather, as once the heater is inserted, it will generate electricity bills regardless of whether the engine needs to be heated. If the equipment operator plugs in the heater every night without considering the situation, it may result in unnecessary electricity bills. However, if the temperature drops unexpectedly and the heater is not plugged in, the equipment operator or timer will need to activate them the next morning, resulting in a hard start.

TwinStat ™  Wiring is an easy to implement solution. The heater equipped with this wiring will only be activated when the outdoor temperature drops below 40 ° F (4 ° C). When the temperature changes during spring or autumn, the heater will remain turned off and therefore will not use electricity. If the temperature drops, the wiring will automatically activate the heater, protect the equipment, and provide all the benefits of engine heating, including easy start-up the next morning.

In typical backup generator applications, the energy consumed by the generator during its service life may far exceed the energy generated. One possible factor is the engine heating system, which is installed in accordance with the NFPA 110 standard for emergency and backup power systems, which requires the generator to be able to withstand full load within ten seconds of engine start-up.

To meet this requirement, many factory manufactured generator sets are equipped with one or two temperature difference circulation engine heating systems. These heating systems can provide necessary engine heating to ensure that the generator set meets load requirements; However, its circulation method is less efficient than similar pump drive devices. In many cases, if the generator set is equipped with a dual temperature difference circulating heater, it can be replaced with a single pump drive device.

Because the temperature difference circulation heater relies on convection to circulate the fluid, the heating element must heat the fluid to a very high temperature to generate flow. During the service life of the heater, this additional power demand will accumulate. In addition, the higher temperature generated by the temperature difference circulating heater may require more frequent replacement of pipeline hoses, which also increases the total holding cost.

In these cases, use a forced loop system (such as Hotstart HOTflow) ®  Replacing traditional convection based heating systems with heaters can greatly reduce electricity costs, up to 35% in some cases. Replacing two convection heaters with a single heater also reduces the complexity of the entire system and will lower maintenance costs. Finally, the pipeline will not be exposed to the high temperatures required for temperature difference circulation, and will last longer between daily maintenance, further reducing maintenance time and costs.
