The advantages of gas heating
Whether in residential buildings or apartments: Almost every second heat generator in Germany is a gas appliance. The fact that heating with gas is so popular is mainly due to the many advantages of gas boilers, which can be roughly divided into two areas: economic and ecological advantages.
Economic advantages of gas heating
The purchase of a new heat generator is always associated with planning and certain acquisition costs. In most cases, the latter determine which heating system is installed. And it is precisely here that the first advantage of gas heating becomes apparent: compared to other heating systems, gas boilers are still one of the cheapest heat generators to purchase. Due to the omitted partly high investment costs, homeowners remain financially flexible.
Cost effective and safe operation
Those who decide to operate a gas heating system benefit at the same time from low consumption costs and high operational reliability. After all, gas boilers have been in use for decades and have proven to be very reliable so far. Last but not least, gas prices are still at a relatively low level. On average, a kilowatt hour of natural gas costs about 6.4 cents. This value can fluctuate greatly depending on the tariff. Compared to electricity (about 28 cents per kilowatt hour), heating with natural gas is nevertheless very favorable. Those who do not have access to a local gas connection can also use liquid gas. The price for a kilowatt hour is about the same as for natural gas. However, system owners need a gas tank for the fuel. You can find out more about this fossil fuel, its types and deposits, and availability in the Fuel gas section.
Near seamless supply and problem-free installation
With a total length of more than 500,000 kilometers, the German gas distribution network is capable of supplying most residential buildings and apartments in Germany with natural gas as a fuel. Since most connections lead directly into the house, the installation of a gas heating system hardly involves any effort.
Once homeowners have decided to use such a heating system, another advantage of gas boilers becomes apparent: Unlike oil heating, such a boiler can be installed almost anywhere. While compact floor-standing units can fit in the attic or in adjoining rooms, homeowners can easily hang gas condensing units in living spaces. Even in kitchen cabinets, a gas condensing boiler will find enough space.
No chimney and storage room needed
By connecting directly in the house, homeowners do not need a storage room or a fuel tank to operate a gas heating system. Only if they use liquid gas instead of natural gas is a liquid gas tank indispensable. This can be set up in the garden, for example. An existing chimney is always necessary. When installing or mounting in the attic, a fireproof roof duct with a small diameter of about ten centimeters is sufficient. If there is a chimney, the exhaust pipe can also be routed through the roof. If the gas heating system uses condensing technology, certain requirements for the exhaust pipes must be observed.
High security of supply and clean combustion
Another advantage of gas heating is the fuel supply. This is considered to be very secure, as global natural gas reserves are becoming ever larger. At the same time, energy suppliers usually conclude long-term contracts with gas exporters, so that demand can be guaranteed for many decades to come. Once the gas boiler is in operation, another advantage of gas heating becomes apparent: among fossil fuels, natural gas burns the cleanest and produces few pollutants. On the one hand, this increases economic efficiency and, on the other, reduces the burden on the environment.
Ecological advantages of gas boilers
The decisive advantages of gas boilers include both the clean combustion technology and the variety of combinations. As gas heating systems are becoming cleaner, they actively contribute to the conservation of available resources. After all, natural gas - despite high reserves - is still a fossil fuel and therefore only finitely available.
Some gas boilers are technically prepared in such a way that they can burn not only pure natural gas, but also that with biogas admixture efficiently and cleanly. In addition, they are able to automatically adjust to different types of gas. In this way, they always convert the highest possible amount of energy into heat at any gas quality.
Operate gas heating systems with solar technology
The sun is one of the most energy-rich heat sources of all, available to us free of charge and infinitely. With the help of solar technology, homeowners can convert solar energy into heat and use it, for example, to heat drinking water or relieve the load on the boiler. Viessmann gas boilers are prepared for connection to a solar thermal system. With just a few simple steps, they can operate in bivalent mode instead of monovalent mode. In this case, the solar thermal system can support the heating system and take over the DHW preparation completely.
Gas heating with heat pumps
In addition to the solar thermal system, a heat pump can also be used for bivalent operation with a gas boiler. In this case, the heat pump not only provides hot water, but also heats the rooms. If peak loads occur, the gas boiler is switched on. In this way, system owners heat extremely efficiently, cleanly and in a way that conserves resources. Last but not least, the state provides attractive subsidies for such combinations, provided the boiler uses condensing technology.
