Highly Efficient

Energy Star's Most Efficient Boiler


The Elite Premier puts everything you love about HTP’s focus on high efficiency in this versatile unit. It is compliant with the NOx emissions limit set forth in SCAQMD Rule 1146.2. resulting in an eco-friendly boiler. The combustion system has a specialized mixer with an internal shutter which seals off a portion of the mixer’s opening to increase the combustion system’s turndown ratio to 10 to 1. The greater turndown allows the Elite Premier to match lower loads, which reduces short cycling, conserves energy and improves component reliability.
