On February 4, 2010, Espar Heater Systems received notice of new EPA validation of E-Guardian heaters specifically for idle reduction in school buses.
This validation covers the following Espar models: E-Guardian 5 (Hydronic D5), E-Guardian 8 (Hydronic D8), E-Guardian 10 (Hydronic D10) and E-Guardian 12 (Hydronic D12), and the Espar Heater Systems Airtronic D2, Airtronic D4 and Airtronic D5. The verification can be found on the EPA SmartWay Verified Technologies Web page listed as FOH (fuel-operated heaters).
Espar has been producing environmentally-friendly heater systems for idle reduction for many years and was an original EPA SmartWay partner. Espar fuel-operated heaters have previously earned EPA validation as well as CARB (California Air Resources Board) approval. EPA requested that manufacturers of fuel-operated heaters apply for validation of fuel-operated heaters specifically for school bus applications. This new validation covers Espar heaters that were previously validated for Class 8 trucks.
E-Guardian heaters provide idle reduction which reduces emissions, fuel consumption, reduces the frequency of oil changes plus provides the added safety of defrosted windows for a clear view of the road and additional interior warmth for passenger comfort.
