A common cause would be that your electric heaters are autosized (or oversized manually) and you have a heating schedule for the thermostat that has an abrupt change (eg: 17C during the night and at 7:30 it goes directly to 19C).
If autosized I would set the heating design day schedule for the thermostat schedule to the upper limit (19C in my example above).
You should probably also ramp your schedule a bit more (go from 17C at 7:00, 17.5C at 7:15, etc until you get to 19c)

Hi all!I have tried to model the energy consumption for heating of a dwelling heated by electric baseboards. All the installed electric baseboards are controlled by a thermostat.However, the results I obtained look weird to me.The heating energy request is not constant during the period but it has a really big peak when the heaters are turnud on and then the request is quite small during the rest of the day (see attached picture). It looks like the heaters are oversized for the dwellings.I tried to check again my code several times but everything seems fine.Do you have any idea what the problem could be?I know it is a vague request, but probably it has already happened to some of you.Thanks,Giusi
