Title: Fluid-Based Electric Heating System with Radiator and Underfloor Mounting Capability Abstract: This invention presents an innovative electric heating system utilizing a heat transfer fluid, designed for installation on existing radiators and underfloor heating networks in residential, commercial, industrial, and agricultural buildings. The system addresses critical limitations of conventional fossil-fuel-based heating systems, including dependency on gas infrastructure, low thermal efficiency (typically 50-70%), high maintenance costs due to moving parts and corrosion, and incompatibility with renewable energy sources. The proposed system comprises a sealed chamber (1) filled with a non-corrosive, anti-scaling heat transfer fluid with thermal stability up to 90°C, an electric immersion heating element (2) with nominal power of 1100W and internal thermostat, a circulation system (4) selectable between a variable-speed pump and a passive thermosiphon mechanism (no moving parts), and an intelligent electronic control unit (5) with automatic temperature regulation (30-90°C range) and energy-saving mode that reduces power consumption to 15% of nominal power (110W) during maintenance. The system offers two configurations: (1) portable/standalone for up to 30 radiator fins (40 m²) with quick-connect fittings, weighing approximately 10 kg when filled; and (2) fixed configuration integrated with building plumbing for up to 50 radiator fins (80 m²) including expansion tank, pressure relief valve, and circulation pump. The heat transfer fluid is glycol-based (30% ethylene glycol + 70% deionized water) with anti-corrosion and anti-scaling additives, stable from -20°C to 90°C. Key innovations include elimination of mechanical wear components, maintenance-free operation for minimum 4 years, installation time under 30 minutes without technical expertise, compatibility with photovoltaic solar panels (12-24V DC input), and production cost between 12-16 million IRR (approx. $250-350 USD per unit for pilot production). The system reduces energy consumption by 50-70% compared to conventional electric heaters (2000-3000W), eliminates gas dependency, and operates with zero combustion-related safety risks. Industrial applications include villa heating, temporary shelters, greenhouses, livestock facilities, caravans, commercial spaces, and humanitarian aid camps in off-grid regions. This invention represents a significant advancement toward sustainable, affordable, and decentralized heating solutions.
