The International Ground Source Heat Pump Association (IGSHPA) is a group of people who work together to make sure that heat pumps around the world are working well and using energy efficiently. Heat pumps are special machines that take energy from the ground and use it to help heat or cool buildings. By joining this group, people who work with heat pumps can learn from each other, share ideas, and create better practices that help us save energy and be more environmentally friendly.
