What no kitchen? No laundry? No other hot water outlets? There are sizing guides from the manufacturers websites to help choose the right model for your needs. Also climate will influence what model you choose because it will determine how much the water temperature needs to be raised from the incoming water to reach the desired level of temperature. The higher temperature change the bigger model tankless you will need.
It should be a 60 gallon heater.
You should have a hot water heater for the kitchen for sure and also to have for the bathrooms. I personally like to wash my hands in hot water not cold.
The source of water into a home has no bearing on the shower temperature. - This is caused or changed by the water heater and any piping and valves between heater and the shower. The fact of the well being source of the water is totally irrelevant in this case.The source of water into a home has no bearing on the shower temperature. - This is caused or changed by the water heater and any piping and valves between heater and the shower.

they have water heater
Replace the shower valve.
Could be water-heater problems or faulty valve.
The kitchen is probably closest to the water heater and the shower is the farthest. Water cools down the farther it travels through the pipes.
Yes it is because that way if you take the hot water shower. The rock's will sock the excessive water.
you have trash in your line take the shower head off and remove trash or possibly in water valve at shower
No, you will have different temperatures of water inside the water heater, which will make it difficult to get a consistent temperature out of a shower valve or faucet. The heater will also not work correctly or efficiently.
when hot waoter comes out of the shower you made have a water heater
Your hot water heater is not large enough.
Many variables need to be supplied here. Size of water heater, Gallons per minute of shower head and volume of water being used. If the water heater is small, you only have 30 gallons of hot water available. If you have a 6 GPM shower head, that is only enough for about a 5 minute shower. If you have had the water heater checked out to make sure the heating element (if electric) isn't corroded or caked with calcium or making a lot of noise (boiling sounds) if it is gas, you can increase the temperature setting on the water heater. This will let you use more cold water and increase your shower duration. Changing your shower head to a low flow type will also increase you soak time. Another thing to consider is the distance of the shower from the water heater. If the pipes have to travel some distance in an uninsulated space, this will lower water temperature as it travels through the pipes. Hope this helped.
