District Heating Systems (DHS) are recognized in the EU as one of the key technologies and measures to reduce greenhouse gas emissions arising from heating buildings and energy consumption. District heating increases energy efficiency, lowers energy costs and reduces environmental pollution. DHS replaces individual heating devices by buildings, which results in a positive impact on the environment due to the reduction of greenhouse gas emissions and PM10 particles.

Energy efficiency is the most favorable ratio between the achieved effect, service, goods or energy and the energy invested. With district heating systems, we at Interenergo Group consistently follow the criteria for energy efficiency as dictated by the Energy Efficiency Act (EED) in the first paragraph of Article 50. The heat produced in our systems reaches and exceeds the set requirements of the said law, which provides our customers with the most energy and environmentally efficient thermal energy.

Wood biomass (wood and wood residues) is an organic substance used as an energy source and is one of the renewable energy sources. Since thermal energy produced from wood is  neutral and does not generate  emissions, it has many environmental benefits.

Benefits of wood biomass:

• Renewable energy source 
• Neutral energy source
• An affordable energy source with a stable price
• Increasing local employment
• Locally available energy source
• Contribution to forest management

Natural gas is a gaseous fossil fuel whose main component is methane. It is the cleanest fossil fuel with low carbon dioxide emissions from combustion and is a versatile and energy efficient energy source in comparison with other fossil fuels.

Benefits of natural gas:

• Natural energy source
• High calorific value
• Affordable
• Savings on heating
• Better combustion with less harmful combustion by-products
• Higher efficiency of input energy using cogeneration plants (CHP)
