TLDR - No. There is a theory that you can run a 12V-rated Chinese diesel heater at 24V if you set the ECU to 24V in the secret admin settings. In my test, I bought the cheapest heater available on eBay for £89. It has the very basic ECU and controller which lets you select 12V or 24V from the secret settings part of the menu. If you change the ECU to 24V, connect a 24V supply and turn it on. It tries to heat the glow plug and then gives a glow plug error and stops. Doesn't even kill it. Fires right back up on 12V. ... https://www.youtube.com/watch?v=YHpzqW_m7UE
