Right on the money.

In our 914 project, I took advantage of the warm air behind the
radiators to warm the cockpit. Simple, litght and efficient, and since
the radiator duct is separate from the engine compartment, zero CO ppm
were found during flight tests.
You need a properly designed radiator duct, though.
