How to Choose a Heating System?

Choosing the right heating system means balancing volume, insulation, and energy: heat pump for efficiency, gas for power, or electricity for simplicity. The secret lies in the emitter: convection for rapid heating or radiation for large volumes to avoid stratification.

Mistakes? Ignoring the building coefficient C, neglecting acoustic comfort, and forgetting about regulation (BMS). A well-sized installation (V x C x Delta T) guarantees profitability and comfort — provided you anticipate maintenance costs and the building's scalability.



Comment bien Choisir un Système de Chauffage ?

Choosing the right heating system is a strategic decision that impacts not only the comfort of your employees and customers but also your company's profitability for the next ten years. Between evolving energy prices and new environmental standards, the choice can no longer be made "by feel." At Climatik, we support our clients through a rigorous analysis of their needs to transform an energy expense into a performance investment.

1. The crucial step: Analyzing your needs

Before even talking about boilers or heat pumps, you need to define your building's thermal profile.

Volume and ceiling height

A 100 m² office with a 2.50 m ceiling height is not treated the same way as a 1,000 m² warehouse with an 8 m ceiling height.

  • Low height: Convection (warm air) or hydronic (radiators) is preferred.

  • High height: Radiant heating (infrared) is preferred to prevent all heat from accumulating at the ceiling.

Insulation level

This is the K-factor (heat loss coefficient). The older and less insulated your building is, the more "calorific power" you will need. Conversely, in an RT2020 building, low power is sufficient, but regulation must be extremely precise.

2. Energy comparison: Which source to choose?

The choice of energy is often dictated by access to networks, but also by your long-term vision.

Electricity: Simplicity, a cost to monitor

  • Usage: Small premises, offices, or supplementary heating.

  • Advantages: Low installation cost, minimal maintenance, immediate responsiveness.

  • Disadvantages: High kWh price. For large volumes, it can quickly become a financial drain.

Gas: The industrial standard

  • Usage: Workshops, shops, gymnasiums.

  • Advantages: Massive power, moderate energy cost compared to electric, mature technology (condensing boilers or gas air heaters).

  • Disadvantages: Requires a connection or a propane tank, mandatory annual maintenance.

Heat Pump (HP): Ecological efficiency

  • Usage: Modern offices, shops, low-consumption buildings.

  • Advantages: For every 1 kWh consumed, it produces approximately 3 to 4 kWh of heat.

  • Disadvantages: High initial investment, performance decreases in very cold weather (except for specific models).

3. Choosing the right emitter: How to distribute heat?

Once the energy is chosen, you need to decide how to "push" the heat into the room. This is where Climatik's expertise makes a difference.

Convection Heating (Warm Air)

Air is heated and then blown by a fan (air heater, rooftop unit, split system).

  • Ideal for: Shops and spaces where rapid temperature rise is desired.

  • Watch out for: Stratification (warm air rising).

Radiant Heating

Tubes or panels directly heat objects and people without heating the air in between.

  • Ideal for: Work zones in large hangars or loading docks.

  • Watch out for: Not suitable if numerous obstacles (tall shelving) block the rays.

Hydronic Heating

Hot water circulates in radiators or underfloor heating.

  • Ideal for: Commercial comfort (offices) and areas where a gentle, constant heat is desired.

Calculating your system's power

To avoid mistakes, our technicians use the simplified formula for thermal needs:

P = V x C x Delta T

Where:

  • P : Power required in Watts.

  • V : Room volume in m3

  • C : Construction coefficient (from 0.7 for very insulated to 2.0 for uninsulated).

  • Delta T : Difference between desired temperature and the lowest outdoor temperature in your region (e.g., 20°C interior - (-5°C exterior) = 25).

Climatik Example: A 1,000 m³ workshop, moderately insulated (C=1.2) with a target of 18°C at -7°C outside, will require a power of: 1000 x 1.2 x 25 = 30000 Watts, or 30 kW.

4. Often overlooked criteria when purchasing

Making the right choice also means anticipating daily constraints.

  1. Noise: In an office, a noisy fan hinders concentration. Check the sound pressure in dB(A).

  2. Maintenance: A complex system is powerful, but are spare parts available? Is local after-sales service provided?

  3. Scalability: Will your business expand? Can you add modules to your current installation?

  4. Regulation: A good system without a good thermostat is a car without a steering wheel. Invest in a Building Management System (BMS) to control your consumption.

Why choose Climatik for your heating decision?

Choosing a heating system from a catalog is a risk. At Climatik, we transform this risk into certainty:

  • Return on Investment (ROI) study: We compare the installation cost against the energy savings generated over 5 or 10 years for you.

  • Multi-brand solution: We are not tied to a single manufacturer. Our priority is the most coherent technical solution for your building.

  • Turnkey installation: From network installation to commissioning, our technicians manage the entire process.

  • Regulatory compliance: We guide you through government aid (CEE) and the obligations of the "Décret Tertiaire" (Tertiary Decree).

Conclusion

Choosing the right heating system means finding the balance between occupant comfort, energy cost, and ease of maintenance. Whether it's a powerful oil generator for a construction site, a reversible heat pump for offices, or a gas air heater for a workshop, each project deserves a customized study.

Are you unsure about the necessary power or the energy to prioritize? Contact the Climatik experts. We will put our expertise at your service for your comfort and savings. With Climatik, choose intelligent heating.
