Decentralized Modular Heating for Every Building Entrance
SECOND HEAT
Decentralized Modular Heating for Every Building Entrance
SECOND HEAT is a distributed heating model combining heat pumps, energy storage systems (ESS), and mining-based waste heat recovery.
The project addresses Ukraine’s critical challenge:
over 50% of centralized thermal generation capacity has been damaged or destroyed.
Concept
Instead of one large boiler plant — multiple independent modules installed near each building entrance.
One module:
• serves 60 apartments
• produces ~300 Gcal annually
• operates up to 8 hours during blackout
• reduces CO₂ emissions by 320 tons/year
Technical Specifications
• Thermal capacity: 180 kW
• Heat pump (COP up to 4.5)
• Mining capacity: 105 kW (immersion cooling)
• ESS: 30 kWh
• Buffer tank: 2000 L
• 20-ft container format
• Installation time: 2–3 weeks
Unit Economics
• Turnkey cost: $160,000
• Annual mining revenue: ~$70,000
• Annual heating savings: ~$15,000
• OPEX: ~$5,000
• Net annual profit: ~$80,000
• Payback period: 2 years
After payback, each module generates stable annual cash flow.
Pilot Phase
60 modules in 3 regions
Total budget: $9.6 million
Expected impact:
• 1,800 apartments secured with reliable heating
• 3 million m³ of gas saved annually
• ~$4.2 million yearly revenue generation
• 60 new jobs
Strategic Impact
• Decentralized resilience
• Lower heating tariffs
• Reduced gas dependency
• Urban energy security
SECOND HEAT — Heat that cannot be destroyed.
Energy that works for communities and investors.
