I have a hot water boiler. Even when constantly calling for heat, I can hear the element relays click on and off to avoid over-pressuring. The recirculation pump stays on the whole time.
(I'm agreeing with you; just pointing out that my system does cut out under normal operation, while calling for heat.)
