Try our climate(Scotland) we had lagged 32mm condense pipes going into 5" cast downpipes and the bloody downpipes froze it was that bad.It's always been required to run in 32mm outside. I've been to jobs where a 32mm condensate has frozen, god knows what it's like with 19mm running outside in winter!
Last year was mental. Recommend all condense pipes in Scotland should be run internally.
