The new, 94%-efficient ModCon Commercial Condensing Boiler from Heat Transfer Products features a high-grade Inconel, load-matching gas burner with a five-to-one turndown ratio, to meet the variable needs for space heating and domestic hot water in a single application. The 500,000 Btu per hour model, for example, will operate as low as 100,000 Btu/h, saving energy on warmer spring and fall days when the heating load is light and spans just a few hours.
