Is Your Business Ready for a Gas-Free Future? Get a Free Two-Part Assessment from Tubman Heating
With gas prices more than doubling in the past five years and supply contracts expiring for most industrial users by 2027, many New Zealand businesses are facing unprecedented uncertainty. A recent survey by the BusinessNZ Energy Council found that nearly half of large gas users have already cut operations, raised prices, or reduced staff – and many more expect to do so soon.
At Tubman Heating, we understand how critical secure, affordable, and sustainable process heat is to your operations. That’s why we’re offering a free, no-obligation two-part energy assessment to help you explore proven alternatives to natural gas — including biomass, electric, and electrode boiler solutions. This comprehensive assessment is designed to give you a clear picture of your current energy usage and identify actionable opportunities for improvement.

Below is a breakdown of how our two-part assessment works.
Stage 1: Free Desktop Assessment
The first step in securing your energy future is our free desktop assessment, a crucial information exchange process. This initial analysis helps us understand your unique energy landscape and assess the feasibility of alternative fuel sources before any on-site work begins.
To make this assessment most effective, we’ll ask you to provide:
- 12 months’ worth of fuel usage information.
- Description of equipment.
- Description of your process.
- Billing and cost information of fuel and electricity.
Our team at Tubman Heating will then thoroughly assess this information to determine:
- Fuel cost comparison between current fossil fuel and direct electrical energy (Electrical boiler or heat pump or both, depending on the process).
- Fuel cost comparison between current fossil fuel and wood-based energy (Wood pellet or woodchip or both, depending on the process).
- Potential cost saving based on market average wood-based energy.
- Carbon emissions and potential emissions reduction.
- Heat load assessment based on existing infrastructure.
- Condition assessment of the existing infrastructure.
The outcome of this desktop assessment is a comprehensive report that details:
- The fuel cost comparison.
- Base load and peak load assessment.
- Carbon emissions comparison.
- Potential operational savings.
- Options and brief technical overview of potential alternative equipment complete with load charts.
- Opportunities for improvement.
This initial phase provides the baseline information to determine if an alternative fuel source will be feasible or possible for your operations.
Stage 2: On-Site Assessment
Based on the insights gained from Stage 1, we will then determine the appropriate level of on-site engagement. Our experienced engineers will conduct a detailed visit to your facility to assess the following key areas:
- Installation constraints, including available footprint versus required footprint for new systems.
- Infrastructure upgrade requirements.
- A conclusion on the full scope of the upgrade project.
- An assessment to determine any associated risks.
- An estimate of the overall project cost.
- Identification of fuel sources and precise fuel cost determination.
- A calculated Return on Investment (ROI) based on operational cost savings versus the cost of investment.
- A high-level Heat-as-a-Service (HaaS) cost option, compared with your projected operational savings.
The Benefits for Your Business
Our two-part assessment provides you with:
- Clear Insights: A detailed report highlighting your energy strengths and areas for improvement.
- Tangible Savings: Identification of actionable opportunities to significantly reduce your energy bills.
- Enhanced Sustainability: Strategies to lower your carbon footprint and achieve environmental goals.
- Improved System Performance: Recommendations to optimize the efficiency and lifespan of your current and future equipment.
