Can you attach a picture of the heater? Industrial tank style heaters usually have a thermostat on the inlet to shut off when the incoming coolant hits about 85F which ideally keeps the engine block about 120F.
If it’s in the rad hose it’s probably not an OEM heater if this is a genset from a major manufacturer.
On standby units they aren’t for starting as much as to keep the engine warm enough to go straight to 1800RPM and immediately accept 100% block load. Depending on the application they are required to do this in either 10 or 15 seconds of a power loss. Just like starting your car and immediately putting your foot to the floor and keeping it there. It only takes a handful of starts like that before the rings grab a liner and it comes outside to visit.
