Thanks for posting this Houptee! A couple follow-up questions:
1) The SH502 is rated for 120v and the SH201 is rated for 115v. You mentioned you can use both heaters? Will the SH201 run hotter than or the same as the SH502?
2) Have you found a long-lasting solution to the drain icing and water under the crispers problem with these samsungs? I hear reports that even the revised and longer heater probe doesn't keep the drain from freezing and I suspect it's also freezing lower in the drain line than the probe can reach. Would it be possible to feed yet another drain heater down the drain line to keep it from defrosted?
