Indicator lights provide real-time status of the heater, enabling users to quickly confirm its operation. This ensures engines are maintained within their optimal temperature range, facilitating easy starts while reducing emissions.

Troubleshooting is simplified with the EVRHEAT Series 20. If a fault occurs, the system promptly detects and deactivates to prevent damage, minimizing downtime, repair expenses, and warranty claims. Clear fault indicators on the display assist users in swiftly identifying and addressing issues in the field.


The EVRHEAT Series 20 features quick response controls, utilizing solid-state technology to react to fluid temperature variations as small as 1 °F. This ensures enhanced temperature consistency and eliminates bothersome low-temperature alerts.

Installation is made effortless with the EVR20, thanks to its adjustable 180° swivel inlet hose barb. This design accommodates plumbing requirements in tight spaces, facilitating simpler field retrofits.

The combination of solid-state temperature controls and a debris-resistant forced circulation pump results in an exceptionally durable engine heating solution. It boasts up to 45% greater efficiency compared to standard thermosiphon (TPS) heaters, leading to lower total cost of ownership.

Efficiency and performance are paramount in engine heating systems. While providing essential benefits to organizations relying on onsite power generation, inefficient solutions can drain resources through excessive electrical costs and frequent repairs. Comparing the Hotstart EVRHEAT Series 20 to other models such as TPS, CB, and CTM can provide valuable insights into optimizing efficiency and performance.
