The way the faucet cartridge is designed it will protect you from large changes in water pressure. This can happen if someone is useing the shower and someone else flushes a tolet there is a sliding valve in the cartridge that will close off hot water supply to protect you from getting scalded.If you are not getting hot enough water there are adjustment you can make to increase the maximum setting.
As long as you are getting good hot water supply in other fixtures in your house I doubt that changeing the water heater is going to help.
I think that you may have a defective cartridge and I would call delta again and give them another chance. They generally have very good customer service, and perhaps the one you talked do did not understand that you have good hot water supply elsewhere.
If you do not have hot enough water to shower valve that can eaisily adjusted by removing set screw that holds the handle on and remove the handle.If there is a white temp. limit disc on the stem then remove it. Slid the chrome sleeve from around the valve body off. You should see a disc that you can slid out a little and rotate to the left a small amount. This adjusting disc and its mating surface have teeth on them that mate. There should be marks on the valve and disc with a arrow on them to show which way to turn for hotter water.Reassemble and check.
If your water starts out hot and then gets cooler while being used and you still have hot water in other places then I think you have a defective cartridge. It should be under warranty. Hope this helps you some. Good luck and thank you.
My shower and tub spout had very low water pressure so I replaced the (single handle) value with a new one. I stilll have the same problem. When I removed the valve and turn on the water the pressure is there.
