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:
🔹 
Winterwarm WWH Series – High-velocity fans for even heat distribution.
🔹

2. Indirect Gas Heaters (Best for Dusty or Ventilated Areas)

✔ Sealed combustion (no fumes inside)
✔ 
Perfect for factories with dust, fumes, or ventilation needs

Top Pick:
🔹 
ATAG QX Series – 94% efficiency with low NOx emissions.



3. Electric Radiant Heaters (Best for Spot Heating)

Step 3: Match Your Industry Needs


4: Consider Running Costs & Efficiency


Key Metrics:

  • Thermal Efficiency (%) – Higher = lower fuel waste.
  • kW Output vs. Space Size – Oversized heaters waste energy.
  • Smart Controls – Programmable thermostats save up to 30% on bills.


Best for Efficiency:

  • ATAG QX Series – 94% efficiency with modulating burners.
  • Rinnai EXH Series – Self-diagnosing for optimal performance.



Step 5: Avoid These 3 Common Mistakes

🚫 Choosing Based on Price Alone – Cheap heaters cost more long-term.
🚫 Ignoring Maintenance Needs – Some systems require more servicing.
🚫 Overlooking Future Expansion – Will your heater cope with growth?
