If you have "delay start" functions on your washing machines (dish & clothes), you can either do dishes overnight or clothes overnight as close to 3-4am as possible (assuming you're waking up around 6 or 7).
There is not a great way to "automate" the heating of water in a traditional water heater and it would be a safety hazard to do so.
The only other good option is an inline electric water heater, but the cost of that will outweigh anything else.
If you're eager to spend money on this, I'd look into newer appliances that you can set to run at a certain time of day if there is absolutely no functionality available.
Your question is too broad,.
