From Coal to Clean Energy: How Boiler Conversions Work

For decades, coal-fired boilers were the backbone of heating systems in New Zealand’s industrial, commercial, and public facilities. But that’s changing fast. With increasing environmental concerns, higher carbon costs, and stricter emissions regulations, many businesses are phasing coal out entirely. Government policies and sector regulations now actively encourage, or require, organisations to move away from coal. 

At Taylors, a core part of our business is helping with that switch, away from coal. We’ve been helping facilities future-proof their operations by converting from coal to cleaner, more efficient alternatives.  

 

Why Switch Away from Coal? 

Coal’s decline in New Zealand comes down to four key factors: 

  • Environmental impact : Coal is one of the most carbon-intensive fuels available, making it incompatible with New Zealand’s climate goals. 
  • Regulatory change : Government targets, such as the ban on new low and medium temperature coal boilers for industrial heat, are accelerating the shift. 
  • Operational costs : Carbon pricing and the rising costs of coal supply make alternative fuels more cost-competitive over time. 
  • Public perception : Many businesses are adopting sustainable practices to meet customer expectations and brand commitments. 

 

Your Fuel Options After Coal 

Every facility has different needs. When planning a conversion, we look at your operational requirements, space constraints, and long-term energy goals to recommend the best alternative.

  1. Biomass : Wood pellets or wood chips offer a renewable, locally sourced fuel option. Biomass boilers can often be adapted from older coal systems.
  2. Electric : Ideal where space, safety, or low maintenance are priorities. Great for hospitals, schools, and office buildings.
  3. Diesel or Gas : Flexible, reliable, and well-suited for combined heating and hot water applications.
  4. Waste-to-Energy : Perfect for the timber industry or facilities with a steady supply of burnable waste. 

The Boiler Conversion Process with Taylors 

  1. Assessment of Existing System
    We evaluate your current boiler, ancillary equipment, and building layout to determine what can be reused and what needs replacing. 
  2. Fuel & Technology Selection
    Based on your heat load, budget, and operational needs, we recommend the most suitable clean-energy alternative. 
  3. Engineering & Design
    Our sister company, Vortex Engineering, designs the modified system including fuel handling (if applicable), control systems, and safety features. 
  4. Manufacturing and Testing
