A system for heating and pressurizing fluid that defines a primary fluid flow path, and may comprise a fluid inlet into the flow path for receiving fluid at an initial fluid temperature, a fluid outlet out of the flow path, a fluid pump configured to raise the pressure of the fluid in the fluid path, and a flow diverter valve configured to divert fluid flow from the primary fluid flow path to a secondary fluid flow path. A fluid heating device may be configured to heat fluid passing through the primary fluid path, and may be incapable of heating the fluid from a first inlet temperature range to the outlet temperature in an outlet temperature range, but is capable of heating the fluid from a second inlet temperature range to the outlet temperature in the outlet temperature range.
