CVC High Efficiency Engine Heater

Hotstart's CVC High Efficiency Engine Heater uses proven air-source heat pump technology to provide the most efficient engine heating solution for standby generators installed in the United Kingdom and Europe. CVC systems use significantly less energy to maintain water jacket temperatures than electric resistance based engine heaters.

The CVC is a high efficiency engine heater capable of reducing generator heating costs by 20 - 40 MWh annually*. Hotstart's active heat recovery system pulls existing heat from the surrounding air and sends it though a vapor compression cycle, delivering heat to the coolant to maintain engine temperatures while idle. This process is more efficient than generating heat through electrical resistance.

The variable speed compressor allows the CVC to provide the proper amount of heat needed based on ambient temperature − no overheating or underheating of the generator. The precision regulation of heat output results in lower annual energy costs associated with generator readiness while also reducing system carbon footprint, contributing to end-user's
net-zero goals.

Standby generators equipped with a CVC engine heater and a standard Hotstart engine heater will reliably start in lower ambient temperatures. The two systems work cooperatively, operating in tandem through fully integrated and programmed controls, providing heating at any temperature. Network connectivity allows operators to remotely monitor heater status, maintaining uptime and engine reliability.
