The advantages of oil heating
Oil heating systems were already increasingly used in the 1950s. Since then, the technology has steadily evolved and is therefore considered mature and safe. And because oil heating systems are among the most widely used heating systems, their technology should be more than familiar to any well-trained heating installer. This makes maintenance easier and can significantly shorten the time in case of repair. But this fact is only one of the many advantages of oil heating systems.
Secure supply thanks to numerous import sources
Another advantage of oil-fired boilers is the availability of fuel. Germany has no oil reserves of its own and imports the fuel from over 30 producing countries. This has many advantages: On the one hand, there is no direct independence between importer and exporter. On the other hand, this results in short transport routes, so there are hardly any supply bottlenecks.
Long-term secure operation thanks to large oil reserves
Even though crude oil is one of the fossil fuels, the operation of an oil heating system is by no means limited in time. This is because the world's reserves and deposits are so large that demand for the next five decades can be met without any problems. In addition, the industry has been working diligently for years on the further development of synthetic fuels and the breakthrough should only be a matter of time.
Supplier diversity increases economic efficiency
The large number of suppliers has another advantage for owners of an oil heating system: they can determine when to refill the tank based on the current prices. Optimally, they can always order the fuel when it is very cheap. Savings can also be made with collective orders or purchases outside the heating season.
Economic operation with efficient heating technology
As already mentioned at the beginning, heating technology is constantly being developed and optimized. Therefore, one of the advantages of oil boilers is their favorable operation, provided that the complete system is adapted to the demand. However, efficiency can also be increased technically. In this case, the magic word is condensing technology.
Condensing boiler technology converts energy into heat with virtually no losses
In addition to calorific value technology, which is still used, condensing technology is now considered the standard in heat generation. The difference between the two technologies lies in the use of so-called condensation heat. This is released when the combustion gases become liquid, i.e. condense. How this technology works in detail is explained in the section on how oil condensing technology works.
Use also possible in new buildings
Contrary to what many people believe, economical operation of an oil heating system in new buildings is by no means impossible. Thanks to modern technology and a variety of combinations, an oil condensing boiler can easily be combined with an environmental heating system such as a biomass heating system or a heat pump. In this way, the oil boiler takes over the back-up function, while the environmental heating system is responsible for heating the rooms efficiently and cleanly. The use in a new building also has the advantage that only little fuel needs to be stored. After all, the heat demand in such buildings is now very low. One of the advantages of oil heating in new buildings is therefore the small amount of space required for the tank. Often a separate basement room can be dispensed with. Space-saving tanks that system owners can install next to the heating system or in the utility room are often sufficient for storing the required fuel.
Combination diversity and future-proof control technology as further advantages of an oil heating system
As already mentioned, modern oil boilers can be easily and quickly combined with another heating system to form a hybrid solution. This increases cost-effectiveness in the long term and also provides the basis for government subsidies. Whether combined with solar thermal, a biomass system or a heat pump, Viessmann oil boilers are already designed ex works for bivalent operation. As an alternative to hybrid heating, modern oil boilers can also be operated with a biogas mixture, thus reducing the burden on the environment.
