Fired heaters vs Electric heaters

Advantages of fired heaters against electric heaters:
High heating capacity at low operating costs, high efficiency in combination with waste gas treatment and combustion air preheating (efficiency > 90 %)

Disadvantages of fired heaters against electric heaters:
More complex installations (chimney, boiler house), thus normally higher initial investments, more maintenance-intensive
