Is it possible for a gas fired boiler to consume more energy when heating intermitently versus having heating at all times?

Your dad is likely right (as usual? :-)). With modern equipment, slow but steady wins the race. I assume we're talking about a modern high efficiency condensing gas boiler. If that's not the case and ...
