Given the declining quality of utility services and rising costs, urban apartment owners are increasingly considering the switch to autonomous heating. While private rural houses often include such systems in their initial design, transitioning to autonomous heating in multi-story buildings requires special permits. Obtaining the necessary documentation is just the first, and often most challenging, step in the redevelopment process. To ensure the system operates efficiently, it’s essential to understand the types of available equipment, their advantages and disadvantages, and potential challenges along with solutions.

Autonomous heating refers to a self-contained system that operates independently of the central utility network. It includes a heating device, pipes, and radiators, with variations based on the energy source and heat carrier.
This system consists of a closed water circuit connected to a central water supply. The water is heated in a boiler, and circulation occurs due to temperature differences within the pipeline.
Advantages:
Environmentally friendly with no harmful emissions.
Quiet operation.
High safety ensured by quality control devices.
Cost-effective maintenance.
Long service life.
Significant savings on utility bills.
Disadvantages:
Expensive and complex installation.
Requires apartment remodeling post-installation.
Periodic inspections by certified professionals are mandatory.
This system includes a heating boiler, fan, and ductwork that distributes warm air throughout the house. As the air cools, it recirculates through filters and radiators before being reheated. Common heat sources include electric coils, gas, or water circuits.
Advantages:
Effective and uniform heat distribution.
Controlled ventilation for fresh air intake.
Reliable and simple design.
No risk of pipes freezing.
Ability to clean and sanitize the air.
Easy to maintain.
Disadvantages:
Dependence on electricity for operation.
Large duct systems take up significant space.
Complex integration of air ducts into existing apartments.
Electric heating is convenient due to its simplicity. It doesn’t require intricate circuits or connections to water and gas lines. Popular options include convectors, fan heaters, oil-filled radiators, infrared heaters, underfloor heating, and heated towel rails.
Advantages:
Eco-friendly with no emissions.
Quiet operation.
Reliable and easy to install without permits.
Portable equipment.
Minimal maintenance required.
Can also heat water for domestic use.
Disadvantages:
Ceases operation during power outages.
Requires separate wiring, enhanced safety measures, and distribution devices.
High energy consumption results in elevated electricity bills.
The shift toward gas-based heating systems in apartment buildings became widespread toward the end of the 20th century. However, as issues with centralized utilities emerged, this trend slowed. To transition to an autonomous system, obtaining approval from city authorities is often necessary, as they prioritize large utility providers.
Seasonal Control:
Freedom to decide the start and end of the heating season.
Adjustable temperatures and customizable on/off schedules.
Cost Efficiency:
Payment is based only on actual energy consumption.
Avoids costs related to heat loss, utility company margins, and other expenses.
System Flexibility:
Choice of heating technology and layout to suit technical and aesthetic requirements.
Energy Efficiency:
Minimal energy usage with effective heat distribution.
Optimized temperatures based on climate and individual preferences.
Dependency:
Relies on consistent energy supply, including gas and electricity.
Interruptions can halt system operation.
Installation Costs:
High initial expenses for equipment, permits, and professional installation.
Additional costs for potential repairs and post-installation renovations.
Maintenance:
Regular inspections and adjustments require time and money.
Backup Systems:
Backup heating devices are necessary for emergencies, leading to extra expenses and storage requirements.
By understanding these aspects, homeowners can make informed decisions about transitioning to autonomous heating, balancing its benefits with potential drawbacks. This approach ensures a system that delivers comfort, efficiency, and long-term savings. (αυτονομη θερμανση σε διαμερισμα κοστοσ)
