We are planning on putting in a woodburner, in the uk they require 'commissioning' by a certified fitter. Is this the same in Spain?

I noticed on another thread that there was discussion as to which way up the flue goes (female up or down) as they seem to be opposite uk to eu?

Are there different qualities of flue? We won't require a liner, as it's just the flue going straight up.

Are there regs about having to have parts that could be touched double lined?

We quite like some of the English stoves, has anyone imported one & is it worth it?

& last question, cast iron v steel bodies?

Thanks
