With Hydrotherm Cast Iron Condensing Boilers... The List Is Almost Endless

The KN Series boiler by Hydrotherm combines the high efficiency and small footprint of modern copper boilers, with the long life and reliability of cast iron boilers.

The KN Series boiler possesses a combination of capabilities and features that provide compelling benefits. The KN Series boiler has literally been engineered to think for itself. Its self adaptive design is tolerant of changing conditions to meet the requirements of real world conditions.

TOLERANCE
TRU-FLOW™ CONTROL IS INHERENTLY CLEAN BURNING.  The KN Series boiler uses a unique Tru-Flow™ control strategy to control the fuel-air mixture at all firing rates and venting conditions. The combustion air is constantly measured to fine-tune the fuel gas flow through the gas valve. As an example, with Tru-Flow™ control the KN Series is insensitive to variations in air pressure, therefore it will automatically correct itself for altitude.
~  Tru-Flow™ control for clean combustion under all conditions
~  Operates at full rated input on gas pressures down to 2" W.C.

RELIABILITY
NO LIMITATIONS ON TEMPERATURE RISE
The gas side design distributes heat evenly across the entire exchanger, losing heat to the water as it travels down. The waterside of the exchanger adds heat evenly as it rises in the casting. These characteristics ensure an even stress distributing with no 'hot' spots within the sections.
The KN Series is designed for balanced temperature rise across each section, further reducing inter-section stresses. The relatively small size of the castings also minimizes stress differences.
RELATION OF WATER PRESSURE AND TEMPERATURE
Unique internal baffle design allows the boiler to operate without 'steaming' at low boiler pressure according to :
Supply temperature (max) = Saturation temperature of water (at boiler supply pressure) -40 Degrees F
