The present invention provides a system, method and apparatus for heating a fluid without a flame. The modular heater (apparatus) that includes an enclosure, a dynamic heat generator disposed within the enclosure, an electric motor disposed within the enclosure, a first fluid connector attached to the enclosure, a second fluid connector attached to the enclosure and an electrical connector attached to the enclosure. The electric motor drives the dynamic heat generator to heat the fluid to a specified temperature without a flame. The first fluid connector connects the dynamic heat generator to a fluid source. The second fluid connector connects the dynamic heat generator to a fluid storage. The electrical connector connects the electric motor to a power source.
