Total Heat System

RuppAir’s unique Total Heat System is the most efficient heating option for commercial and industrial applications, including airplane hangars, distribution centers, sports stadiums, factories, and warehouses. The Total Heat System continuously introduces variable amounts of fresh air over a nearly 100% efficient direct fired burner and recirculates unused heated air to eliminate cold drafts and stratification and create a positive space pressure. The Total Heat System is the best choice for year round comfort and energy savings. When combined with HVLS fan technology, cost savings and comfort are even greater.
