I would set your thermostats to 55, if you really want to push it you could try 50.
I don't know what you mean by "radiators closed" but if they have water in them you don't want them to freeze. Frozen pipes cause a lot of damage many times what you would save in 5 or 10 years if you don't catch it in time.
I don't know what you have to burn the wood in, but it will be interesting to see if you can generate enough heat in the colder days.
