Danger ?
I just read on the Cadet Co. website
I. When connecting a heater to 120 volts:
• use a 20 amp single pole circuit breaker
• use 12/2 with ground wire
• electrical code restricts max load to 1,500 watts
• do not add more than 1,000 watts to existing circuits
- My electrician is planning on adding 1,500 watts to existing breaker box. Is this a danger? The electric baseboard heat 1500 watts will be used only at night.

There isn't enough information here to provide a definitive answer. But unless you are very close to the edge, another 1500 watts isn't likely to break the bank (or the main breaker).

I think they are referring to 1500w on a circuit, not your service. How do they know that you don't have a new 1/2 empty 200A panel?
Also this is quite misleading. Code does NOT restrict anything to 1500 watts. I wish they would refrence an article when they write things like that. You need to stay at 80% of a rated circuit. Using a 20a circuit as an example; this would be 1920 watts for 120 volts and 3840 watts for 240v.

Bear in mind that any single load of 1200 watts or more will require a dedicated circuit, serving no other loads, per the 2002 NEC, and may not be added to an existing circuit.
If the heater load is expected to run for more than 180 minutes (and it may), the circuit must also be derated to 80% of it's maximum capacity. Be sure to double check this work as it is performed, as electrical heater loads are the most common cause of overloading and wiring damage on residential branch circuits.
