My daughter recently bought a house and the hot water in the showers is consideribly cooler than the faucets. I thought that there was a regulator for the hot water that could be turned up, but I don't see one. I suspect that there is a safety for over temp to prevent scalding. Do I just need to turn up the temp on the water heater? Any help is appreciated.

Please tell us what is the brand and model number of the faucet, Thanks.
