How the heaters work
The two most common heaters are the diesel heater and the gas heater, though the gas heater is currently the most popular. Both models are air heaters and work in the same way: a burner, powered by electricity, heats the air, which is then distributed inside the vehicle by a fan. The difference between gas and diesel heating is that gas heating uses liquid gas as fuel and diesel heating uses diesel as fuel. The heater, like your air conditioner, is operated via a control element in the motorhome.
Differences between gas heating and diesel heating
It is not possible to make a general statement about which parking heater is better, and it depends entirely on the individual needs and behaviour of the user. However, there are differences that can make a decision easier.
As already mentioned, the most commonly used heater is currently the gas heater. The clear advantage here is that its performance is very reliable, it is very quiet compared to diesel heating and it also requires little maintenance. Heating with gas also has no effect on the fuel consumption of your tank and is fed from liquid gas bottles that are stored and connected in the motorhome.
This does have an impact on the storage space of your campervan. A medium-sized 11-litre bottle weighs a hefty 22 kg and having a spare bottle with you is recommended for longer holidays. Since the heater runs on gas, this also means that it has to be refilled when it is used up. This can sometimes be a real challenge, especially abroad, as there are no uniform standards for gas bottles across countries. However, this can be solved with an adapter kit. So if you are going on a longer trip, find out about the country-specific conditions in advance.
If you have a heating system that runs on diesel, you are guaranteed to save some storage space compared to the gas heater, because the diesel heating system uses diesel directly from the fuel tank, which is fed to the heating system by a diesel pump. In contrast to the gas heater, which requires less electricity to transport the fuel to the heater due to the pressure in the gas bottle, the electricity consumption of the diesel heater is somewhat higher. On the other hand, diesel is easily available at any petrol station, making the diesel heater an uncomplicated and reliable companion for longer trips and also for camping in very cold weather.
