For choosing one energy fireplace that properly covers the heating needs of a space 80 sq.m., there are various parameters that must be taken into account, such as the size of the space, the insulation of the house, the temperature of the area and the type of fuel (wood or pellets).

Thermal Capacity Calculation

The heating requirement depends on the fireplace power, which is measured in kW (kilowatts). For a space of 80 sq. m. with good insulation and without extremely large thermal losses, the thermal capacity of the fireplace should be around 7-10kWIf your home has poor insulation or you are in a colder area, you may need a fireplace with more power.

For example:

• Good insulation: 7-9 kW.
• Medium insulation: 9-12 kW.
• Poor insulation or cold climate: 12-15 kW.

Types of Energy-efficient Fireplaces for 80 sq.m.

1. Wood Fireplace (Cassette or Energy Fireplace)
   • Heating capacity: Usually from 7kW to 12kW.
   • Application: Ideal for spaces that have a traditional design and want the atmosphere of wood. It offers high thermal efficiency with proper combustion and low emissions.
   • Advantages:
     • Greater feeling of warmth due to natural wood.
     • It can be connected to an existing flue.
   • Price: Approximately €2,000 to €4,000 (depending on the brand and model, without installation).
2. Jackie Pellets
   • Heating capacity: Usually from 8kW to 12kW.
   • Application: Ideal for greater autonomy and economy, as pellets are easier to automatically feed into the combustion system.
   • Advantages:
     • Less hassle for maintenance and fueling.
     • Increased efficiency and lower operating costs compared to wood.
     • More automation and programming capabilities.
   • Price: Approximately €3,000 to €6,000 (depending on the brand and model, without installation).
3. Air Heating System (Air-Heated Fireplace)
   • Heating capacity: From 7kW to 12kW.
   • Application: Ideal for rapid heat diffusion throughout the space. It usually does not require much maintenance costs and is more economical in energy consumption.
   • Advantages:
     • Fast heat dissipation.
     • It can be expanded with duct systems to heat other areas of the house.
   • Price: Approximately €2,500 to €5,000 (depending on model and requirements).

Factors Influencing Choice

• Heating Needs: If the space is open or has large windows, you may need more power.
• House Insulation: In the case of a poorly insulated house, the need for more power increases.
• Combustible: Pellets are usually more economical and more convenient for continuous burning without constant monitoring, while wood requires more frequent stirring and addition of fuel.
• System Selection: If you wish to heat other spaces (e.g. bedrooms or other areas of the house), you may need a system with ducts or radiators.

Energy Saving Fireplace Prices for 80 sq m (With Installation)

Below is a cost estimate for the purchase and installation of an energy-efficient fireplace for 80 sq m:

• Wood Fireplace (with installation): From €2,500 to €6,000 (depending on the model and complexity of the installation).
• Jackie Pellets (with placement): From €3,500 to €7,500 (depending on the brand and the automation system included).
• Air-heated Fireplace (with installation): From €3,000 to €6,000 (depending on heat dissipation needs and system characteristics).

Conclusion:

For a space 80 sq.m., you will need an energy-efficient fireplace with an efficiency of around 7-12kWIf your house has good insulation, a model with 7-9kW power will be sufficient, while for more open or less insulated spaces, you may need a more powerful model.

The cost for one energy fireplace with place generally ranges from €2,500 to €7,500 (depending on fuel type, heating needs and installation services). It would be a good idea to request quotes from professionals to receive an accurate cost estimate and choose the appropriate heating system for your space.
