How to tell which auxiliary heater you have...?

[Kiwi Ange]

How can you tell which heating a MP has, there seems to be two types. One that can run for an hour and one that can run overnight. How can you tell which it which...? The spec only lists below details:

HY2 Radio remote control for warm-air auxiliary heater
HZ0 Electrical auxiliary heating
HZ1 Auxiliary hot-air heater

Thanks in advance.
