District heating system – Future plans
Connection of the two separate networks financed by the Environment and Energy Operational Programme (Structural Funds) - executed
Use of geothermal energy in the district heating system Installation of efficient gas boilers replacing the old ones Further extension of the district heating system with residential and
industrial consumers is possible and considered
Future demand for the district heating network

Produced geothermal heat
Optimal capacity
• Phase 1: 3,5 MW capacity; 38 400 GJ heat
• Phase 1+2: 18,3MW capacity; 254 500 GJ heat
• Phase 1+2+3: 28,2 MW capacity; 382 100 GJ heat
Execution Phases (1) • Install geothermal heat plant in heat
transfer station no. 202.• Drill 1+1 wells• Pre-heat secondary loop return
water
Phase 1
• Connect Széchenyiváros system into geothermal heat plant
• Drill 3+3 wells (total 4+4 operates)• Pre-heat primary loop return water
Phase 2
• Connect Árpádváros system into geothermal heat plant
• Drill 2+2 wells (total 6+6 operates)• Pre-heat primary loop return water
Phase 3
• Safety – Reduce drilling risk• Adapted milestones• Earlier operation• Income• Subsidy
Advantages
• 3 parallel pipeline is installed (2 small + 1 large)
• Large pipeline is unused in phase 1• 2 small pipelines reinject in phase 3
