The costs of modernizing a heating system vary significantly and depend on several factors, including the type of new heating system, the size of the house, and the complexity of the installation. On average, the expenses for heating system modernization can range between 5,000 and 15,000 euros.
Cost Factors for Heating
The expenses for modernizing the heating system can vary greatly, depending on the chosen technology, the size of the house, and specific requirements. Generally, the costs can be divided into the following categories:
Acquisition Costs: These include the cost of the new boiler or heating system, as well as any additional components such as storage tanks or solar panels.
Installation Costs: This includes the costs for dismantling the old system, installing the new heating system, and any necessary adjustments to piping and the chimney.
Ongoing Costs: Ongoing costs include the energy consumption of the new heating system, as well as maintenance and repair costs.
Subsidies and Incentives
There are numerous subsidy programs available to help homeowners cover the costs of heating system modernization. In Germany, government programs, such as those offered by the KfW Development Bank, provide grants and low-interest loans for switching to renewable energy sources and improving energy efficiency.
KfW Subsidies
The KfW Bank offers specific programs for funding energy-efficient renovations. Homeowners can save up to 70% of the costs through subsidies, especially when switching to a heat pump.
BAFA Subsidies
In addition to KfW, there are also subsidies from the Federal Office for Economic Affairs and Export Control (BAFA). These are primarily aimed at the use of renewable energies, such as biomass heating systems or heat pumps.
Heating System Modernization in Older Buildings: The Best Solutions
Modernizing heating systems in older buildings can present particular challenges. Often, the existing heating systems are not suitable for modern technologies, requiring extensive adjustments.
Energy Saving Ordinance (EnEV) and Building Energy Act (GEG)
These regulations sometimes mandate the modernization of outdated heating systems. This indirectly promotes investment in modern and efficient heating technologies.
Challenges for Heating in Older Buildings
Insulation: Many older buildings are not adequately insulated, leading to significant heat loss. Before modernizing the heating system, it's important to assess and, if necessary, improve the building's insulation.
Lack of Space: In many older buildings, the space available for new heating systems is limited, which can restrict the type of heating technology that can be installed.
Outdated Infrastructure: The existing heating infrastructure may need to be adjusted or completely replaced, which can incur additional costs.
Modernization Options
When modernizing an older building, there are several approaches:
Replacing the Boiler: Replacing an old oil or gas boiler with a modern system is often the first step. Condensing boilers or heat pumps are recommended in this case. Condensing boilers utilize the exhaust heat to provide additional heating support, significantly increasing efficiency.
Incorporating Renewable Energy: Installing solar panels or a biomass heating system can significantly increase efficiency and reduce dependency on fossil fuels. For example, solar thermal systems can assist with water heating, thereby reducing heating costs.
Optimizing the Heating System: Smaller measures, such as hydraulic balancing or installing thermostatic valves, can also contribute to improved efficiency. Hydraulic balancing ensures that all radiators in the house are evenly supplied with heat, reducing energy consumption.
Heating Systems for Older Buildings
Choosing the right heating system for older buildings is a crucial decision that affects both the budget and ongoing costs, as well as living comfort. This section covers various heating systems for older buildings, their advantages and disadvantages, and the relevant legal requirements and subsidy opportunities.
Gas Heating
Gas heating systems remain one of the most popular heating methods in older buildings. They are relatively cost-effective to purchase and offer high efficiency, especially when using modern condensing boilers.
Oil Condensing Boilers
Oil condensing boilers are another option for older buildings, but they are increasingly subject to legal restrictions and environmental concerns.
Hybrid Heating Instead of Pure Oil or Gas Heating
A hybrid heating system might involve a gas or oil heater providing up to 35% of the heating. There are various combinations of heating systems, such as a combination of solar thermal systems and heat pumps. Hybrid heating systems can switch between different energy sources as needed, allowing for optimal adaptation to current conditions.
