UFT Boiler (Wall & Floor Mount Models)

The UFT is HTP's medium mass high efficiency boiler. This advanced modulating gas condensing boiler has a 316L stainless steel fire tube heat exchanger with a 96% AFUE rating. It is equipped with a state of the art gas leak detector and has ultra-low NOx emissions, making the UFT eco-friendly and your best option in today's green market.

Turndown Ratio 10 to 1

Combustion system is equipped with a specialized mixer on the inlet of the blower to increase boiler turndown to a 10 to 1. Modulating technology matches fuel consumption to demand to provide high system efficiency even during low load conditions. Greater turndown allows the UFT Boiler to modulate at lower firing rates which reduces short cycling, conserves energy and improves component reliability.

Installation Flexibility

Top and bottom supply and return connections featured all units allows for greater installation options.

Excellent Venting Options

Vents in inexpensive, easy to install PVC pipe, CPVC or Polypropylene Overall vent length on standard 100 feet in 3" pipe or 50 feet in 2" pipe

The UFT Advantage

An extremely durable laser welded 316L stainless steel heat exchanger features high temperature aluminum fins that are inserted into the individual fire tube circuits to increase heat transfer capabilities and resists corrosion. Its unique downward fire tube design provides optimal condensation drainage and produces self-cleaning for low maintenance. The compact storage size of the unit allows for low pressure drop and higher efficiency. It's equipped with an outdoor sensor that adjusts the UFT's set point to match seasonal conditions which improves the overall operating efficiency.

Energy Star Rated

The UFT Boiler has been rated one of the Most Efficient Boilers of 2017 by ENERGY STAR! HTP's high efficiency residential boilers save energy, money, and protect the environment. While traditional boilers are not able to modulate, high efficiency boilers modulate which allows the boiler to run longer and at lower fire rates while maintaining the desired temperate in your home. This improves efficiency and saves energy.

The UFT puts everything you love about HTP's focus on high efficiency in this versatile boiler. It is compliant with the NOx emissions limit set forth in SCAQMD Rule 1146.2. resulting in an eco-friendly boiler. The UFT is ETL listed and exceeds the latest minimum efficiency requirements of ASHRAE 103 with an AFUE rating of up to 96%. If just 1 in 10 households used ENERGY STAR certified heating equipment, we would prevent annual greenhouse gas emissions of 12 billion pounds!
