Ultratec High Efficiency Series

Where Power Meets Precision

Efficiency Redefined: Fully condensing hot water boilers for commercial and industrial applications
  • 25% Typical Energy Savings
Our maximum efficiency boiler design offers 10% fuel savings compared to standard models, operating efficiently with flow and return temperatures of 80°C (176°F) and 60°C (140°F ) of flow and return.. With exceptionally low standing heat losses of just 0.06%, our system maximizes energy retention and reduces waste. Featuring a low NOx burner and an advanced micro-modulating control system, the BKBD boiler optimizes performance for your needs, delivering energy savings of up to 25%
  • Easy Installation & Maintenance
The range is easy to install, with units up to 293kW (1MMBtu) seamlessly fitting through standard doorways.  Thanks to material choice and their unique design, BKBDs require minimal maintenance
  • Multi-fuel & Hydrogen Firing
Flexing to your needs, BKBD Boilers fire on gas or oil, or have dual fuel applications with the ability to change on the fly. Both the burner and boiler are also ready to run on hydrogen
  • 5 Year Warranty
The heat exchanger is manufactured using 316L stainless steel, chosen for its inherent corrosion resistance, allowing us to confidently offer a five-year warranty on its durability and performance
  • Low Emissions & Compliance
Drive your sustainability agenda with a low NOx, fully modulating burner that guarantees 3% 02 throughout the firing range, while the micro-modulating control system ensures easy adherence to compliance regulations. Both are included in the BKBD suite
  • Patented & Approved Technology
The BKBD boiler range is patented in the UK and USA. It is also CE, UKCA and ASME approved
  • Designed to fit into Existing Systems
Engineered as a four pass watertube with a unique tube profile design, all boilers are 100% condensing at 90°C (194°F) with an 11°C (20°F) differential regardless of the new or existing system
  • BKBD Range
BKBDs are available in eight models, with outputs ranging from 147kW to 1788kW (0.5 to 6 MMBtu)
