Steam/vacuum heating systems are employed in thousands of old tall buildings and even relatively new ones. Although considered obsolete, these systems excels any other in simplicity and resilience and can match modern efficiency standards after thorough retrofit. Efficient and simple, the NextGen vacuum heating is suggested for existing steam heating systems retrofit and for new installations that use modern technologies and materials. 2014 NGRID study demonstrated 25-50% fuel savings from steam heating retrofit, 9 years follow-up confirmed results.
