Without knowing the efficiency rating of your heating system and the home ACH leakage rate to the outdoors your heating guy might have a point, however 4 to 6 degree change should not cause increased usage or heating system to struggle if its efficient and properly maintained...Usually changing the thermostat two times a day is enough. For example if I'm at work all day 8+ hrs why would I be maxing out the heat in my home if i wasn't there? Consider purchasing a NEST thermostat and allow it to learn your homes algorithms and compare the energy or gas usage. This is a smart thermostat that you can control with and App. on a Iphone or equivalent and review energy or gas recorded usage. "The less it runs, The less it costs" Regards, Scott
