Highly Efficient
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.
Multiple Options to Exceed Your Needs
The Elite Premier is available in seven different models ranging from 80,000 to 399,000 BTUs. It is suitable for any residential application in both natural gas and liquid propane. It can be used in radiant flooring, with fan coils, base boards, snow melt, and domestic hot water (with indirect tank or volume water heater) or pool heating (with indirect tank).
