Water heater temp adjustment

We have a 2013 198rd. Our water is a little hotter than we'd like. Is there an adjustment we can do?

Thanks!

Marty and Kristina Parmer

Welcome to the forum!

Probably not. Check the knob on the gas valve if there is one...it will say cold/warm/hot, if not then most newer water heaters have a fixed temperature sensor that is mounted to the surface of the tank. It is possible that you might be able to install a sensor with a different setting...see your dealer or maybe someone who has changed one will chime in.

We simply turn the cold water on a bit to moderate the temperature to our liking.

Water Temp

I took my new TT out for the first time Friday. I fired up the water heater and on mine there is a temp adjustment. At first it WAY too hot but I dialed it back and now it is tolerable.

Some folks have said that if there is not thermostat control (and many TT don't have one) you can lower the temp by adjusting the HW bypass valve. Open up the bypass a bit and some cold water will bypass the heater and mix in with the hot.

I've not tried it yet, but it sounds do-able.

Usually the gas/electric wh will have pre-set thermostats attached to the tank wall. Whereas the gas only models will be similar to a house wh with the temp control on the gas valve.

When we are bathing our children we always use all the hot water in the tank when filling the tub and then turn off the HW until they have finished soaking/playing. Hot water temp is definitely at scalding temps for a child straight from the tank. When we are not on full service hook ups, I simply turn off the pump once the tub is full and kids are in it.

The best fix/ mod would be to install a thermostatic mixing valve to temper the hot water, but I have not got around to doing that. On our model the water lines run under the sofa to the hand sink and tub at the back. It would be pretty simple to install it under the sofa I would think, and still have straight, scalding hot water at the kitchen sink.

That is how I have set it up at our house, I have a mixing valve on the hot water line in such a location that the laundry room and kitchen get hot water straight from the tank, but all washrooms are on the other side of the valve and get tempered hot water that is not hot enough to accidentally scald a child (last I checked it maxed out at about 48'C (118F), but my hot water tank is at about 66'C (150F))

Some have an adjustment and some heaters don't.

If you want it colder just turn on cold water more, unless you are in The Phoenix area, then there is not any cold water, coming thru the water hose. It is all hot.

if you have a winterizing bypass you should be able to temper the water by just barely opening the valve between your cold water inlet to heater, and hot water outlet from heater. This will allow cold water to mix with the hot water coming out of heater. Would adjust until you get desired temp.
