Why install a diesel heater?
The conservatory has an area of around 6 × 6 meters with a room height of around 2.5 to 3 meters. Two sides are adjacent to the house, the other two are half-timbered with single glazing – a structure that loses a lot of heat in winter and is difficult to heat evenly. Previously, the room was heated with a 2000 watt electric radiator, which ran continuously to keep the temperature reasonably stable. Despite the high power consumption, the heat distribution remained uneven: It became noticeably warm in the immediate vicinity of the radiator, but significantly cooler in the far corners of the room.
A diesel heater works in a fundamentally different way. It burns diesel or heating oil and converts the resulting heat into warm air via an integrated heat exchanger, which is distributed evenly throughout the interior by a fan. The effect is a significantly more homogeneous temperature distribution and faster heating, even in larger or poorly insulated rooms.
In contrast to electric heating, which converts electricity directly into heat and therefore incurs high operating costs, the Hcalory HBH2 diesel heater uses the energy content of the fuel much more efficiently. It is specified with a maximum heat output of 8 kW. However, this figure describes the theoretically possible heat output if the heater were to burn around 0.8 liters of diesel per hour – with an energy content of around 9.8 kWh per liter of diesel. As the HBH2 consumes only 0.12 to 0.45 liters of diesel per hour in practical operation according to measurements, the actual usable heating output is realistically between 1.2 and around 4.5 kW. This output is sufficient to reliably heat the approximately 90 m³ conservatory, especially at moderate outside temperatures.
Thanks to the app control and the automatic start/stop mode, the parking heater regulates its output as required, which is particularly beneficial in cold weather. This further reduces energy consumption and makes operation independent of the power grid – a decisive advantage, especially for applications in campers, motorhomes or places without a fixed power supply.

Design, workmanship & scope of delivery
The housing of the Hcalory HBH2 diesel heater is made of robust aluminum and is around 1.8 kilograms lighter than previous models. The material not only ensures stability, but also improves heat dissipation on the surface. Thanks to its compact design, the heater is easy to install and is suitable for permanent installation in conservatories as well as for use in smaller vehicles, motorhomes or campers.
Structure and mode of operation
The diesel heater works according to a simple but efficient principle: a small combustion chamber is continuously supplied with fuel via a diesel pump. At the same time, a fan draws in fresh air, which is mixed with the injected diesel and ignited by a glow plug. The heat generated is transferred to a compact heat exchanger, which heats the ambient air flowing through it. This warm air then enters the interior via an air outlet or diffuser.
The exhaust gases from the combustion process are routed to the outside via a flexible stainless steel exhaust hose, while a separate fresh air duct ensures clean supply air. The system is therefore closed and completely separates the combustion air from the room air – a key safety aspect, especially when used indoors.
The integrated 5-liter tank supplies the heater with fuel. With an average consumption of 0.2 to 0.3 liters of diesel per hour, one tank of fuel lasts for around 15 to 20 hours of operation. Power can be supplied either via the 230-volt power supply unit or via a 12-volt or 24-volt power source, such as a battery. This means that the diesel heater can also be operated off-grid, i.e. independently of the power grid – for example with an off-grid PV system or in a car.
The Bluetooth remote control and the removable LCD panel make it easy to control: temperature, fan speed and operating mode can be conveniently adjusted. The automatic start-stop mode switches the heating off as soon as the set temperature is reached and on again when the room temperature drops.

Installation of the diesel heater
The Hcalory HBH2 diesel heater was installed on the inside wall of the conservatory. The aim was to install the heating system in a space-saving, efficient and safe manner. It is particularly important that the flue gas hose is properly routed to the outside and that the interior is sufficiently ventilated to ensure safe combustion and air circulation.
Step-by-step installation
- Attaching the mounting plate to the wall
A sturdy wooden panel was used as the base, which was attached to the wall with robust metal brackets. It serves as a stable base to safely support the weight of the heater and minimize vibrations. The mounting plate also provides a clean separation between the wall and the appliance, ensuring reliable air circulation behind the heater. When attaching the bracket, make sure that the surface is absolutely horizontal – this makes it easier to connect the flue gas and hot air pipes later on. - Attach and screw on the heater
The diesel heater has feet with drill holes on the underside, making it very easy to screw onto the wooden panel. The aim of this step is to achieve a vibration-free and stable mounting in order to reduce running noise and ensure a long service life for the components. It is important that the air outlets remain unobstructed and that no material is in direct contact with them that could be deformed by heat. - Connect exhaust hose to exhaust bracket and seal joints
For the exhaust gas routing, heat-resistant exhaust paste was first applied evenly to the pipe ends. Only then were the pipes and brackets inserted into each other and then screwed together. This sequence ensures that the sealant is evenly distributed and that no cavities are created when it is inserted. The aim is to achieve a permanently gas-tight connection, as escaping exhaust gases can be harmful to health. After curing, the joint should be checked again to rule out leaks. - Drill an opening (25 mm) to the outside and route the flue gas pipe
The wall breakthrough was made directly after the wooden panel had been installed, once the exact flue gas paths had been measured. The hole with a diameter of around 25 mm was positioned in such a way that the exhaust pipe can be routed as short and straight as possible. A slight outward inclination prevents rain or condensation from entering the pipe. When feeding the pipe through, ensure that there is sufficient distance from combustible materials. - Establish power connection via the supplied power supply unit
The heater requires a reliable power supply for the glow plug, fan and control electronics. There was already a socket outlet at the installation site that provided sufficient protection for the high starting currents of the heating system. The connection is made via the 230V power supply unit supplied, which provides the necessary voltage for the starting process. Alternatively, the power supply can be provided by a 12V or 24V battery, for example for off-grid applications or in vehicles. All cable connections should be laid neatly and protected against moisture. - Fill the tank with diesel and bleed the system
Finally, the integrated 5-liter tank was filled and the system bled so that the diesel pump delivers fuel evenly. When filling, diesel should be filled using a funnel or hose to avoid contamination in the tank. After the first start, the pump is slightly audible until the line is completely filled. As soon as the flame is burning steadily, the system continues to work automatically.
The installation of diesel heating in the conservatory requires precise work, clean seals and safe exhaust gas routing. All connections were carefully sealed with exhaust paste and checked for leaks. A CO detector in the room is essential to ensure that the heating runs safely in the long term. It warns of leaks in good time and makes a decisive contribution to operational safety.

Safety & exhaust gas routing
Installing a diesel heater indoors or in a mobile home requires special care. It is crucial to understand risks and control them with appropriate measures.
Possible security risks
- Carbon monoxide (CO): Incomplete combustion or leaks in the flue gas path can lead to CO entering the interior. CO is odorless, colorless and dangerous even in low concentrations.
- Exhaust gas and heat damage: Hot exhaust gas (>150 °C) can cause thermal damage to adjacent components, insulation or cables; contact can cause burns.
- Fuel risks: Although diesel/fuel oil is less volatile than gasoline, it can ignite if there is a leak; the smell of diesel in the passenger compartment indicates leaks or spilled fuel.
- Electrical risks: Undersized cables, missing fuses or loose terminals cause heating, contact fires or failures (especially with starting current).
- Lack of air / negative pressure: A lack of supply air or blocked intake worsens combustion; soot formation, flame break-off and rising CO values are possible consequences.
- Condensate & rainwater: Incorrectly routed flue gas pipes can lead condensate back into the appliance or allow rainwater to penetrate; there is a risk of corrosion and malfunctions.
- Vibration & loosening: Vibrations loosen clamps and clips; over time, leaks occur in the exhaust or fuel system.
Safety precautions and their effect
1) Exhaust gas routing (tight, short, safe)
- Continuous tightness: Moisten all plug-in connections in the exhaust path with heat-resistant exhaust paste before plugging them together, then plug them completely into each other and screw them together. Prevents CO/exhaust gas from entering the interior.
- Slope to the outside: Run the flue pipe out of the room with a slight slope (slightly deeper on the bore side) so that condensate and moisture can drain to the outside. Prevents water ingress and corrosion.
- Thermal shielding: Wrap exhaust pipe with heat protection tape and provide heat shielding plate or distance to combustible materials at penetrations. Reduces the risk of fire and contact.
- Keep the blow-out zone clear: Position the end piece so that exhaust gas does not flow back into windows, vents or intake areas. Prevents exhaust gas recirculation and CO enrichment.
- Vibration-proof clamps: Use stainless steel clamps with sufficient width; tighten after the first hour of operation and regularly thereafter. Works against loosening.
2) Fresh air & combustion air
- Separate paths: Always supply combustion air from outside, spatially separated from the flue gas outlet. Ensures clean combustion, prevents backflow.
- Intake protection: Protect intake opening against splash water and dirt (cap/filter), do not place in dust or snow swirls. Prevents blockages and soot formation.
3) Fuel system
- Tight lines: Select a fuel-tight fuel hose and secure it on both sides with suitable hose clamps. Works against leaks.
- Clean filling: Use a funnel/hose when filling; remove spilled residues immediately. Avoids odor and fire load.
- Decoupling the diesel pump: Mount the pump elastically (rubber holder) and at the correct angle (manufacturer’s specification) so that the delivery rate and noise behavior remain stable.
4) Electrical safety
- Adequate fuse protection: Provide your own fuse suitable for the maximum current (start phase ~120 W); use an existing socket with adequate fuse protection. Prevents line overload.
- Cable cross-section: Dimension power supply and DC cables sufficiently, strain-relieve connections and protect against moisture. Reduces voltage drop, contact heat and failures.
- Cable routing: Distance to hot areas (flue gas/radiators), with heat protection conduit if necessary. Prevents insulation damage.
5) Room and operational safety
- Install CO detector: Fit carbon monoxide detectors in the occupied area and near the installation, test regularly. Early warning of malfunctions.
- Ensure ventilation: Sufficient basic ventilation in the installation room; prevents oxygen deficiency and flue gas recirculation.
- Provide fire protection: Fire extinguishers (fire class A/B) ready to hand; clear escape and shutdown plan. Minimizes damage in the event of an incident.
Checklist: safe commissioning & control
- Visual inspection of all exhaust connections (paste beads, clamps, seat) before the first start.
- First start in observation mode: Exhaust odor outside, no odor inside.
- CO detector test via test button, check battery/mains.
- Check power supply for heat/hum (socket, power supply unit, terminals).
- After 30-60 minutes of operation: retighten the clamps, check the flue gas path again.
- Regular maintenance: Visual inspection monthly during the heating season, check seals every six months, keep flue gas end clear.
Indicators for problems (act immediately)
- Diesel smell in the interior → Check fuel leak or exhaust gas leak, interrupt operation.
- Visible smoke/smoke at the breakthrough → Leak in the flue gas path; switch off immediately.
- Unsteady flame, frequent switch-off → Check supply air/exhaust gas path, keep intake free.
- Unusual noises from the diesel pump → Check fastening/venting/fuel supply.
- asbestfrei
- einfache Handhabung
- hohe Gasdichtigkeit
- einfache Anwendung ohne Demontage
- hervorragende Hitzebeständigkeit
Operation and control of the heating
The Hcalory HBH2 diesel heater is not only easy to install, but also versatile to operate. It can be controlled either via the integrated LCD display, the Bluetooth app or a wireless remote control. This means that the heater can be conveniently operated both stationary – for example in a conservatory – and mobile in a motorhome or camper.
Control via the LCD display
The LCD control panel is permanently connected to the heater, but can be flexibly positioned using the extension cable supplied. This means that the display can also be mounted in the interior and conveniently used as a remote control without having to stand directly next to the heater.
The following functions can be controlled and read via the display:
- Switching the heating on and off
- Selecting the temperature or power level
- Control of voltage, pump frequency and operating time
- Activation of plateau mode (2,500 m / 5,000 m)
- Display of error codes in the event of faults
Advantage: Fast, direct operation without a smartphone; ideal for stationary operation.
Disadvantage: No option to save timers or schedules – these functions are only available in the app.
Control via the Hcalory app
The Hcalory app is the most convenient way to operate the heating. It connects via Bluetooth and works independently of WLAN or the Internet.
Functions and modes:
- Temperature mode: The heating switches on and off automatically as soon as the temperature reaches or falls below the desired temperature.
- Advantage: Energy-saving and ideal for continuous operation.
- Disadvantage: Short switch-on and switch-off intervals can be audible in small rooms.
- Power mode: The heat output is set manually via levels – regardless of the room temperature.
- Advantage: Constant heat emission, e.g. with open doors or frequent ventilation.
- Disadvantage: No automatic switch-off – regular checks necessary.
- Timer function: Enables time-controlled starting and stopping, for example as overnight heating or for automatic morning operation.
- Advantage: High level of comfort, especially in mobile homes or with fixed heating times.
- Disadvantage: App must be actively connected to apply changes.
- Plateau mode: Reduces the injection quantity for altitudes (2,500 m or 5,000 m).
- Advantage: Clean combustion in thin air, less soot formation.
- Disadvantage: Slightly reduced heat output in valley locations.
The app also displays the voltage, current room temperature, radiator temperature, fan speed and consumption in real time.
Important: The app only needs to be actively connected during programming or direct control via Bluetooth. As soon as schedules, timers or operating modes have been saved, the heating works autonomously – it reliably executes the saved sequences, even without an active Bluetooth connection.
Bluetooth remote control
The Bluetooth remote control is particularly practical for everyday use when no app connection needs to be established. It provides access to the most important basic functions without the need for a smartphone.
Functions of the remote control:
- Switching the heating on and off
- Increase or decrease temperature
- Activate or deactivate the timer
- Status display via LED
This control unit is ideal for use in motorhomes, campers or in larger rooms where the display is not directly accessible.
A typical application scenario is to start the heating remotely, for example from bed or before entering the conservatory – this way, the room can already be preheated.
Reliability in operation
In daily operation, the heating works reliably and evenly. The diesel pump delivers the fuel constantly, creating a stable flame and preventing temperature fluctuations.
Thanks to the combination of manual power mode, automatic temperature control and app-supported timer operation, the Hcalory HBH2 can be flexibly adapted to any situation – from quickly heating up a room to economical continuous operation overnight.

Practical test and experience
The diesel heater was tested in continuous operation for several hours. It heats the room by around 2-3 °C per hour and produces uniformly warm air that is well distributed throughout the room.
Experience shows: The automatic mode saves noticeable amounts of fuel, as the heating switches off automatically as soon as the desired temperature is reached and restarts when required. This keeps the room temperature constant while consumption remains at a very low level.
Advantages of diesel heating
- High heat output with low consumption
- Independence from external power supply
- Control via app or remote control
- Durable components with a robust design
- Low maintenance requirements
Another advantage: The Hcalory HBH2 diesel heater can be operated not only with conventional diesel, but also with heating oil or so-called HBV fuels.
HBV diesel (hydrogenated vegetable oil, also known as “HVO diesel”) is a synthetic biofuel produced from vegetable oils or waste fats. It burns cleaner than conventional diesel, reduces soot formation and CO₂ emissions and is therefore particularly suitable for indoor applications or operation in garden sheds.
It is even technically possible to use vegetable oil – old frying fat, for example – as long as it is filtered and brought to room temperature. However, it should be noted that the higher viscosity can cause deposits to form on the nozzle and in the combustion chamber. To counteract this, the heater should be regularly “burned free” with commercially available diesel or additives.
Disadvantages of diesel heating
Despite many advantages, there are also some points that should be considered:
- Noise development: The diesel pump produces a rhythmic clicking noise that can be heard in very quiet environments.
- Odor development on starting: In the first few seconds after ignition, a diesel odor may develop briefly until combustion is stable.
- Exhaust system: The exhaust hose must be checked regularly for leaks to prevent leaks and CO entering the interior.
- Maintenance: After long periods of operation, soot deposits can build up in the combustion chamber or on the glow plug – regular cleaning extends the service life.
- Temperature control: In very small rooms, the heating switches on and off relatively frequently due to the high heat output, which can make operation somewhat unstable.
Overall, the HBH2 diesel heater impresses with its efficiency and flexibility – the ability to use different fuels makes it a versatile solution for stationary use as well as for operation in motorhomes and campers.

Diesel heating in motorhomes, campers and other applications
A diesel heater is now the preferred solution when it comes to heating in a motorhome, camper or truck. Unlike a gas heater or water heater, it does not require an external tank or gas cylinders, but taps directly into the vehicle tank or uses an integrated fuel tank. This makes them particularly safe, efficient and flexible to use.
Thanks to direct access to the vehicle’s diesel supply, the heating in the motorhome works independently of external energy sources. There is no need to refill or check gas cylinders, which not only increases convenience but also safety. A diesel heater is therefore particularly suitable for long journeys or self-sufficient operation on remote pitches.
Comparison of different heating systems in the vehicle
| Type | Advantages | Disadvantages |
|---|---|---|
| Diesel parking heater | Efficient, simple refueling via vehicle tank, independent of the power grid | Pump noise and fan slightly audible |
| Gas heating | Quiet, reliable, proven in the camping sector | Regular cylinder replacement, gas testing, higher installation costs |
| Water heating | Even heat distribution via heating circuits | High power consumption, longer heat-up time |
The diesel parking heater has established itself as the standard, particularly in the motorhome sector. Manufacturers such as Webasto, Eberspächer and Planar offer models that can be retrofitted in almost any vehicle. The same applies to the Hcalory HBH2, which can also be used in smaller vehicles, boats or construction containers thanks to its compact design and universal power supply (12 V, 24 V or 230 V).
Other possible applications
In addition to the classic use in motorhomes or trucks, a diesel heater is also ideal for camping, camping, fishing or in outdoor huts where there is no fixed power supply. With an off-grid PV system or a battery, the heating system can be operated completely independently and provides a reliable source of heat even at sub-zero temperatures.
The Hcalory HBH2 consumes an average of around 0.2 liters of diesel per hour, making it significantly more efficient than electric heaters. While heating with electricity quickly results in high energy costs, diesel heating enables a consistent and cost-effective heat supply – both stationary in the home and mobile when camping or traveling.
Whether in a camper, caravan, truck, boat or small garden shed: Diesel heating offers advantages wherever a constant heat source with low consumption and high efficiency is required – ideal for anyone who wants independent, flexible and energy-efficient heating.
Maintenance and retrofitting
A diesel heater is virtually maintenance-free and requires hardly any care during normal operation. Occasional refilling of the fuel is sufficient to ensure reliable operation. Nevertheless, some components should be checked regularly: These include the exhaust pipe, the diesel pump and the air supply, as soot or deposits can build up over time. A visual inspection every few months ensures that the heating system is always clean and efficient.
Anyone using an older heater in their vehicle can easily retrofit it with a modern model. Installing a new diesel heater is usually straightforward as long as there is enough space for the tank, exhaust gas routing and air heater. Especially in motorhomes, campers or trucks, retrofitting offers a considerable increase in comfort, as the systems today are more compact, quieter and more economical than older models.
For stationary applications, it is also worth taking a look at the implementation of similar projects. In my article “Installing a diesel parking heater permanently in the workshop – explained step by step”, I show in detail how an 8 kW parking heater can be permanently installed – including exhaust gas routing, power connection and safety measures.
The “mobile heater box” on my website also offers a practical alternative to retrofitting in the vehicle. It combines a diesel heater with an integrated tank in a compact housing and is ideal for garden sheds, workshops or off-grid applications.

My conclusion on the test of the Hcalory HBH2
After several weeks of practical use, the Hcalory HBH2 diesel heater has proven to be reliable and efficient. In conservatories, it ensures even heat distribution and reliably prevents frost without consuming unnecessary amounts of energy. The combination of compact design, robust workmanship and simple controls makes it a versatile solution for a wide range of applications.
The option of operating the heating system independently – either via the power grid, a 12V or 24V battery or an off-grid PV system – was particularly impressive. This makes the HBH2 not only suitable for permanent installation in the home, but also ideal for mobile use in motorhomes, campers or trucks. The heat output is impressive for its size, and consumption remains pleasingly low at an average of 0.2 liters of diesel per hour.
The Hcalory HBH2 is a real alternative for anyone looking for additional heating or who wants to reduce the amount of electricity used for heating. It works quietly and efficiently and offers a high level of user convenience thanks to the app control and timer function.
The Hcalory HBH2 diesel heater is therefore a convincing solution both for stationary operation – for example in conservatories, workshops or garden sheds – and for retrofitting in vehicles. It combines flexibility, performance and safety in a compact system and is therefore a clear recommendation for anyone who wants to heat efficiently and independently.
Summary
The blog post “Why install a diesel heater?” describes in detail the installation and practical experience with the Hcalory HBH2 diesel heater – a compact, energy-efficient and versatile alternative to conventional electric heaters.
A 2000-watt electric radiator was previously used in the 6 × 6 meter conservatory with single glazing and high heat loss, which caused high electricity costs and only heated unevenly. By installing the diesel heating system, it was possible to achieve an even temperature distribution. The appliance burns diesel or heating oil, generates warm air via a heat exchanger and distributes it evenly throughout the interior.
With a consumption of just 0.12 to 0.45 liters of diesel per hour, the effective heating output is between around 1.2 and 4.5 kW – enough to reliably heat even larger or poorly insulated rooms. The integrated app control, automatic start/stop mode and operation via 12 V, 24 V or 230 V make the heater particularly flexible and also suitable for use in motorhomes, campers, trucks or boats.
The article also explains the design, technical data, installation, flue gas routing and safety measures in detail. The installation was carried out on the inside wall of the conservatory with secure sealing of the flue gas pipe and installation of a CO detector. The temperature, timer and fan speed can be controlled via app, display or remote control – even independently once schedules have been programmed.
In the practical test, the HBH2 impressed with a stable flame, quiet operation and low consumption. In addition to diesel, heating oil, HVO diesel (HBV) or even filtered vegetable oil can also be used – the latter, however, with regular cleaning to avoid deposits.
The article concludes on a positive note: the Hcalory HBH2 offers an efficient, safe and cost-effective solution for heating with diesel instead of electricity – whether stationary in a conservatory, workshop or garden shed or mobile in a motorhome or camper. Anyone looking for an independent and economical heating system will find a real alternative to electric or gas heating systems here.
FAQ – The 10 most frequently asked questions about installing a diesel heater
1. why install a diesel heater?
A diesel heater offers an efficient way of heating independently of the electricity grid. Compared to an electric heater, it saves energy, reduces operating costs and provides evenly warm air – ideal for the conservatory, motorhome or camper.
2 How does a diesel heater work?
The heater burns diesel or heating oil in a combustion chamber. The heat is transferred to the room air via a heat exchanger and distributed evenly by a fan. Exhaust gases are routed outside through an exhaust pipe – safely separated from the indoor air.
3. how high is the consumption of a diesel heater?
Depending on the heating level and model, consumption is between 0.12 and 0.45 liters of diesel per hour. With a diesel price of €1.70, this results in heating costs of around €0.20 to €0.75 per hour. This means that heating with diesel is significantly cheaper than heating with electricity.
