Typically it would mean that the pump was air locked and not able to circulate Bleed the air from the point at the front of most pumps.Or it could be seized and not turning ,check if power is available at the connections in the motor , if so pump may be burnt out.
The heat you feel may be conducted heat from the boiler only

Forced-air Heating
An integrated system for both space and water heating. Heating is accomplished in a condensing heating module having a small hot water storage reservoir to reduce burner cycling during periods of low demand. The space heating system includes a fluid flow loop with a fluid circulating pump for circulating a heat transfer fluid in the loop from the heating module to a remote space heating heat exchanger. The heating module can also supply hot water for service use. The system may be configured either as an open loop system, in which the space heating and water heating subsystem are combined and share common lines, or a closed loop system, in which the space heating subsystem fluid flow loop is isolated from the water heating subsystem.
