A diesel heater is a rare blessing in a cold and distant landscape, where the temperature is dropping, the pass is climbing, and the fuel station is a long way behind. The Hcalory HBH-3S diesel heater is made for this kind of adventure.
The 5kW diesel heater features a 5L fuel tank, automatic altitude control, improved combustion structure, a quieter fuel pump, app-controlled carbon cleaning, and weather-resistant design. It does not promise to deliver the maximum heating performance, but rather to eliminate some of the weak points of the diesel heating setup: troublesome cold starts, variable altitude performance, carbon buildup, fuel line issues, and noise.
5L Fuel Tank Size Offers Balance Between Run Time and Heat Output
The fuel consumption rate is what determines the travel efficiency of a diesel heater and defines the balance between the run time and the heat output. The HBH-3S heater uses a 5L fuel tank. The consumption rate varies between 0.098L per hour on the lowest settings and 0.358L per hour on the highest. Thus, in theory, the 5L fuel tank offers a 41-hour run time at the lowest 0.098L/h consumption rate. At the same time, it is not recommended to use the lowest settings for the prolonged heating because the ambient air temperature, wall insulation, and room volume will also define the balance. At the lowest setting, the HBH-3S diesel heater will be suitable to provide a stable nighttime temperature. The higher settings ensure a quicker warm-up and more substantial heating.
A more comprehensive approach is better for the long-distance diesel-heated travel, and a 5L fuel tank allows for a convenient balance between the consumption and the heat output. You can select the required output to quickly heat the space at the lowest consumption rate. The higher settings can be introduced to compensate for the heat loss at the lower outside air temperatures.
Heater Automatically Adjusts Altitude Settings up to 5000 Meters
The altitude control is one of the critical differences between the standard diesel heater and the high-altitude diesel heater. The reason for the special consideration is the combustion instability at high altitudes due to the reduced air pressure and density.
The HBH-3S diesel heater allows for automatic altitude compensation and therefore adjusts the air/fuel ratio for stable combustion up to 5000 meters above the sea level. In other words, the fuel/air ratio can be manually adjusted or automatically compensated for the differences in the air density at various altitudes, ensuring stable combustion, preventing carbon buildup, and eliminating the risks of detonation. This feature is especially useful for the HBH-3S heater when the camper or the vehicle climbs and descends the mountain passes at various altitudes. There is no need to remember to change the altitude settings every time when the air pressure changes: the automatic altitude control function handles the compensation adjustments. Thus, the altitude compensation eliminates one of the primary sources of instability and inconvenience in the high-altitude diesel heating.
Cold Start Made Easier with Preheated Combustion Chamber
The reliable cold start capability is critical for the diesel heater at the subzero temperatures. The HBH-3S preheats the glow plug during the one-minute warm-up cycle prior to initiating the fuel pumping to improve the cold start performance. The basic principle is rather simple: a cold diesel fuel requires more energy for ignition than the warmed engine. The one-minute preheating allows the heater to produce more heat at the start and therefore achieve a better cold start performance. According to the manufacturer, the automatic heater HBH-3S can start at the temperatures as low as -40C and as high as +40C. It features an improved aluminum radiator structure with increased surface area to better utilize the produced heat: the 1.8 kg structure compared to the Hcalory previous 1.6 kg version.
The improved combustion chamber structure is supposed to compensate for the losses during the prolonged operation at the reduced power to ensure stable and even heating. The enhanced heater structure also minimizes the heat loss in the combustion chamber itself, thus improving the overall efficiency and promoting the stable operation.
Carbon Buildup Is Taken Care of with a Simple One Touch Cleaning
Carbon buildup is a normal occurrence in the diesel heaters, especially when operated at the reduced power during the prolonged operation. The accumulation of the soot on the heater components leads to the deterioration of the combustion performance and causes significant delays in the maintenance schedule. The automatic carbon cleaning function of the Hcalory HBH-3S eliminates one of the major carbon-related maintenance tasks: the cleaning of the internal combustion parts. With the touch of a button, the carbon cleaning procedure can be initiated: the app-controlled automatic heater goes into a higher power mode to burn off the carbon deposits and then finishes the cleaning procedure. Additionally, the carbon cleaning maintenance schedule is indicated with a 100-hour mark. Thus, the carbon cleaning procedure takes care of the carbon buildup on the critical components, and it is up to the user to maintain other parts of the heater.
Fuel Pump Noise Is Minimized for Quieter Night Operation
The continuous dripping of a fuel pump at night in an insulated van can be unbearable. The automatic HBH-3S heater utilizes a quieter fuel pump that minimizes the dripping noises associated with the standard diesel heaters.
The fuel pump itself is a necessary component of the diesel heater, but it does not have to be loud. The quieter pump reduces the overall noise that can be disturbing, especially at night. However, the pump noise is not the only source of the sound: the fan, the combustion chamber, and the exhaust also contribute to the overall level. Thus, the HBH-3S heater is not completely silent, but the modification eliminates one of the annoying night noises of the diesel heater. The app-controlled heater also offers a manual and an automatic mode to manage the heat output. The manual mode is suitable for an occasional use when the user knows for a fact that the van or the camper will require a certain amount of heating. The automatic mode manages the heat level based on the temperature difference. The app also offers additional features, including the altitude control, the timer function, and the carbon cleaning procedure.
5kW Diesel Heater for the Small Spaces Heating
It is not always the highest heat output that determines the performance of the diesel heater in a confined space: the manual and the automatic modes offer a more flexible approach to the temperature management. A 5kW output is sufficient for the small rooms and campervans with limited insulation. Thus, the nighttime temperature in an insulated van can be easily sustained without the expensive modifications to the insulation or the roof. By using the manual mode, the user only has to change the heat setting occasionally to compensate for the heat loss.
Does Hcalory HBH-3S Diesel Heater Worth Considering?
The best diesel heater for cold weather and long-distance travel is only as good as its installation and the proper service. The automatic altitude control, increased radiator size, and the improved combustion structure still require the correct exhaust setup to perform at the advertised levels. The cold start performance and the fuel economy are optimized when the proper voltage is used. Thus, the Hcalory HBH-3S heater is worth considered by the campers, the van owners, and the cold-weather explorers that seek a flexible and reliable system without the constant adjustments and modifications.
