Carver 1800 heater too hot on lowest setting. Thoughts?

[Tassle]

Hi all,
I have a 1993 Swift Challenger with a Carver 1800 air heater.

I was hoping to be able to use the caravan off-grid in winter and spring by running the heater the lowest setting overnight. (Don't worry, I have carbon monoxide and fire alarms!). To my surprise, I found that even in temperatures approaching zero, the lowest setting on the heater heats the van until it is uncomfortably hot. If I turn it off, I'm freezing by morning!

Does anyone know of a solution to this? Or can anyone who recommend a replacement gas heater with a thermostat that can turn it on and off to maintain a set temperature? I know many heaters can do this on electricity, but I'm not aware of one that can do this on gas?

Thanks for your thoughts!

The more modern Truma have thermostat control and run on gas and/or
electric. Would be a complete replacement plus rewire. Have a look at Propex a UK company they do a gas heater which would be easier to install than Truma 3000 series units.

Carver/Truma used to sell a thermostat for the 1800 heater but it only modulated the heater between maximum and minimum - if minimum is too warm it would have the same effect as the OP is experiencing.

To achieve the OP's requirements, it would need a modern heater with automatic ignition.
