Heat Transfer Products’ new mod/con commercial condensing boiler features a high-grade Inconel load-matching gas burner with a 5:1 turndown to meet the variable needs for space heating and DHW in a single application. The 500,000 Btu/hr. model will operate as low as 100,000 Btu/hr. to save energy. Stack two at a time to double capacity while maintaining the same small footprint.
