Heating the Work n Play

[Walks]

I know there are various threads and I have searched for them but i haven't been able to find what i am after.

Looking to heat my Work n Play van at night times. I'll have 200Ah of LiFePO4 batteries on board so a lot of useable power.

Are there any 12V heating options? Do I use a 240V fan heater. I have a generator to charge the batteries thought the day if it gets to low. It does have a dometic air con that also has heating but it is not reverse cycle and im unsure if it will run of batteries.

I don't want to spend a fortune on a diesel heater and I want to stay away from gas even though others are using them.

So what are my options or is it not possible?

I'm currently investigating a heat exchanger.
It runs hot water from your water heater through a heat exchanger, and has a 12 v fan to move the air. The water circulates back into the hot water unit. I've shown s link in another thread. I'll dig it up.
