Diesel Heater FAQs: Your Ultimate Guide

When considering the addition of a diesel heater to your caravan or RV, numerous questions might arise. This comprehensive FAQ guide is designed to address the most common inquiries, ensuring you make an informed decision about the best diesel heater for your needs. Whether you're exploring the chilly landscapes in your caravan or simply seeking a cozy atmosphere in your vehicle, understanding the intricacies of diesel heaters is crucial. Let's delve into the details.

What size diesel heater should I choose?

The size of your diesel heater, whether it's a 2KW or 5KW model, depends on several factors:

  • Cold Locations: If you're planning to spend considerable time in snowy or cold areas, a more powerful heater is advisable.

  • Vehicle Size: For larger vehicles such as caravans or large motorhomes, a 5KW heater will quickly warm up the space.

  • Window Considerations: Large windows can lead to significant heat loss, necessitating a more robust heater. If in doubt, opting for the larger 5KW model is recommended, as it can be adjusted to lower settings to achieve the ideal temperature, offering both fuel and power efficiency.
     

Will the diesel heater emit any smell?

Properly installed diesel heaters should emit minimal odour due to their efficient combustion. However, an incorrectly fitted or sealed exhaust vent can lead to the smell of fumes inside your vehicle. If you notice a burning rubber smell, inspect and possibly replace the rubber or silicone gasket beneath the heater.
 

How much power does the heater use?

The amount of power usage will depend on the make of your diesel heaters. For instance, high-quality diesel heaters such as those from Eberspacher are known for their incredibly low power draw, while cheap Chinese diesel heaters will tend to use more power. As a general rule though, diesel heaters consume about 10 amps for a few minutes during the startup and shutdown phases, before dropping down to between 1 and 3 amps, depending on the model.
 

How much fuel does the heater use?

As with power usage, fuel usage varies depending on your heater. The Eberspacher AX1 D2 uses roughly 0.28L of diesel per hour, giving you around 40 hours of heating from one 10-litre diesel fuel tank.
 

Can I always run the diesel heater on a low setting?

While operating on a low setting is possible, doing so for extended periods can lead to carbon buildup on the glow plug. To maintain optimal performance, run your diesel heater on high for at least 15 minutes once per month.
 

What is the purpose of the rubber gasket, and how do I seal the diesel heater properly?

The gasket insulates the unit, prevents exhaust fume intrusion, and reduces vibrations. For improvements or replacements:

- Apply temperature-resistant silicone sealant.

- Use a cut-to-size silicone sheet.

- Opt for liquid gasket products like Permatex.

 

Can I get spare parts for my diesel heater?

Yes, a range of spare parts is available for purchase. Check our spare parts page or contact us if you can't find the required part.
