NORA emphasizes which aspect of oilheat systems for sustainable practices?

The emphasis on using high-efficiency equipment in oilheat systems aligns with sustainable practices because it significantly reduces energy consumption and minimizes environmental impact. High-efficiency equipment is designed to optimize fuel usage, which leads to lower greenhouse gas emissions and decreases the overall carbon footprint of heating systems. This focus reflects NORA's commitment to advancing technology that not only meets heating needs effectively but also promotes energy conservation.

In contrast, traditional heating methods might not incorporate the latest advancements in efficiency and can lead to higher fuel usage and emissions. The exclusive use of biodiesel, while beneficial in certain contexts, does not encompass the full range of efficiency technologies available. Lastly, using lower quality materials contradicts the goal of sustainability, which seeks durability and efficiency in equipment to enhance the long-term viability of heating solutions.
