Natural Gas vs Electric Heat for Large Spaces
Introduction
Heating large areas like warehouses requires careful consideration. Choosing between natural gas and electric heating can impact efficiency, costs, and environmental sustainability. This comparison highlights the advantages of natural gas heating for a warehouse requiring about 600,000 BTUs (gas) or 175,000 Watts (electric). Read on to explore the Natural Gas vs. Electric Heat debate.
Efficiency and Practicality – Natural Gas vs. Electric Heat
In a warehouse of this size, only 3 natural gas units are needed. By contrast, about 30 electric units using 480V service are required to provide the same level of heat. Fewer units mean easier installation and simpler maintenance.
Cost and Infrastructure – Natural Gas vs. Electric Heat
Electric heating systems demand more from electrical infrastructure. Using our example would require around 360 amps with 480v electric service. This raises initial installation costs if amp space needs to be expanded. Operating expenses are also higher. Electric heat would cost around $23 per hour (using $0.13/kW, 175 kW total), compared to just $9 per hour (using $1.50 per therm, 6 therms total) for natural gas. Over time, this difference adds up, making natural gas the more economical option.
Environmental Impact – Natural Gas vs. Electric Heat
Electric heaters tend to produce a larger carbon footprint. On average, they emit about 60% more CO2 than natural gas systems. This is mostly due to emissions from electricity generation. Choosing natural gas can help reduce overall environmental impact, supporting sustainability goals.
Conclusion
Natural gas heating offers greater efficiency, lower costs, and fewer emissions than electric heating. With fewer units needed and lower hourly expenses, it’s a smart choice for large spaces. While electric heating has its uses, natural gas stands out as the better option—especially when long-term savings and environmental concerns matter. In regions where it’s allowed, natural gas heating delivers strong benefits in both performance and sustainability.
