Installation & Operation 
Aluminum block heat exchanger with integrated copper waterways ensures maximum heat transfer with minimal heat loss
Enhances cascade system efficiency with multiple units operating at low fire versus one unit operating at high fire to satisfy demand
Uses less energy compared to standard units
Reduces NOx emissions up to 75% compared to standard efficiency boilers 1
Make it easy to diagnose and service with common parts for all ThermaForce units
A total of four moving parts, unmatched in the industry, simplifies servicing—fan, gas valve, damper and boiler pump
Provides operational status, troubleshooting information and allows setting adjustments
Extra-long pipe fittings with notched sides for easy gripping with a wrench
Uses less electricity than a standard pump
Adjusts the boiler supply temperature automatically based on outdoor temperature fluctuations
Up to 96% AFUE and ASME-rated 3
