Step 1: Calculate Your Heating Needs


Key Factors to Consider:

  • Factory Size (m²) – Larger spaces need higher BTU output
  • Ceiling Height – High ceilings require more powerful airflow
  • Insulation Quality – Poor insulation increases heat loss.
  • Process Requirements – Some industries (e.g., food, pharmaceuticals) need precise temperature control.


Pro Tip: Use our free heating calculator or consult our experts for a custom heat load assessment.



Step 2: Compare Heater Types



1. Warm Air Heaters (Best for Large, Open Spaces)

✔ Fast heating with powerful airflow
✔ 
Ideal for warehouses, workshops, and hangars

Top Picks:
🔹

🔹

Step 3: Match Your Industry Needs


4: Consider Running Costs & Efficiency


Key Metrics:

  • Rinnai EXH Series – Self-diagnosing for optimal performance.



Step 5: Avoid These 3 Common Mistakes
