- I have a 5kw diesel heater that provides heat. I have a vent blowing in 15cfm of fresh air from the outside into the inside (in order to maintain healthy co2 levels for 1 person).
I am trying to determine the coldest temperature my campervan can be in, so that the heater is still able to keep the van at 21C, while still being able to blow 15CFM air into and out of the van.
Here is an earlier post figuring out the need for ~15cfm per person of fresh air to maintain less than 1000ppm co2.

I set this up today, let the CO2 ppm reach 1600 and then turned on the fan, it was slowly lowering with me in it, but the heater turned on to max power and it was using plenty of diesel. Outside it was only -3C. Does this mean that if i want to explore areas that are around -30C, I will need a much bigger heater?
