As I mentioned in Post #2, it's better to use a cheap zero-crossing SSR than a relay.
Regarding other posts here - modern tank thermostats (I assume this is a modern tank!) are not directly in contact with the water - they fit in a thin tube which projects into the tank - the thermostat is dry - it's the contacts that fail due to overload and arcing (switching an inductive load) - an SSR removes all that.
