Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

There's a small grey aquastat control (probably Honeywell) on the front of the tank. It has a dial to adjust the temp but just turning up the temp is not a solution since you risk scalding from too hot water. If you're willing to risk that (not advisable with the elderly or small children) then that's all you have to do. But to be safe a tempering valve needs to be installed by a plumber on the hot water line out of the tank. The tempering valve will mix some cold water with the too hot water out of the tank bringing it down to a safe temp.
