Is that what happens when you turn on a tap in your bath room? The boiler comes on immediately. The fire stops when the tap is turned off. This is the way the inline heater works.
A portable radiator heater has a thermostat switch to turn on and off the supply. There is no circulation pump.
What is missing in your simple (basic) assumption? If you have a small room, the boiler temperature may not change.
====================
A storage tank works the way you have described, between the charging cycles.

Subject: [EnergyPlus_Support] on/off boiler
I am trying to model a very basic water heating system . The system consists of:
1) Boiler
2) Circulation pump
3) Radiators
in each time during which the boiler is turned on, the boiler operates at the full load, delivering the amount of energy equal to its design power.
In fact, what I want is to simulate the oscillations of the air temperature of the room because of the radiator i have. the boiler works at its full capacity till the outlet water temperature of boiler reachs 80°C. Then it stops until the water temperature get lower than 80°C once again.
i want to know could i model this ? and help me about it please.
thanks
