While the specific carbon footprint of an air cooled heat pump chiller may vary depending on the specific electrical grid of a region and the unit’s efficiency, replacing a building's fossil fuel heat sources with electrically powered alternatives, like Trailblazer HP, can provide building owners with additional ways of reducing the direct use of fossil fuels in their building. Future changes to the electrical grid to be more heavily powered by renewable energy sources are an important step for electrically-powered alternatives to realize their full potential.
