Pennant® Domestic Hot Water Boiler

Versatility Meets Performance

The Pennant line of fan-assisted, modular domestic hot water boilers from LAARS ranks among the industry’s most versatile and environmentally friendly with NOx emissions under 10 ppm and thermal efficiencies up to 85%.

Pennant Pump Mounted and Volume models feature a factory mounted three-way valve and automatic by-pass system designed to maintain a minimum boiler return temperature of 120°F (49°C) preventing heat exchanger condensation and extending boiler longevity. Built to withstand return water temperatures as low as 70°F (21°C), Pennant Low Temperature models are the perfect choice for low temperature.
