Why is the water out of my kitchen faucet, barely hot?

Question

My water heater is new, and in the garage. My kitchen faucet is on the opposite end of the house (1400 sq ft home). The water out of my kitchen faucet doesn't get very hot, while the shower(s) have actual hot hot water. my water heater is set to medium-high which is the most energy effiecient setting.

Answer 1

You have a long "run" to supply hot water to the kitchen. The hot water line must not be insulated--should be. What size of pipe is it? Propably 1/2". You may want to consider using 3/8" copper tube for this run to the kitchen and insulate it. You may also want to consider raising the temperature on the settings a little more. Take the "tip" off the kitchen faucet and clean it out to insure a full flow of water coming out.

Answer 2

Was the water hot with your old water heater or was it the same as with the new one? Do you have a single handle faucet in your sink? Sometimes the mixing valve can get out of kilter in those faucets and not mix the hot and cold properly. I had one that I never got hot water out of...only warm. I finally replaced the mixing valve and now it works properly. Turn off the cold water under the sink and just let the hot water run and see if it gets hot. If so, repair the valve. If not then it could be the long run and you may have to crank up the water temp a bit.

Answer 3

Did you have this problem with your old water heater? If not you could have trash in your faucet on the hot water side or any value you have on the hot water line from the water heater to the faucet.This is usually cause by a chemical deposit that build up in the pipe specially if you have some galvanized pipe.When you undo the connection to install your new water heater, some of this deposit breaks loose and stays in the pipes specially when you have to knock on the connections to jar them loose.

If you had the problem before you replaced the old water with the new one, you may still have a built up of chemical in your pipe or in your Faucet. In both cases check or replace your faucet, which would about the least expensive, rather ripping out your pipes.

Answer 4

gene is right. At the very end of the faucet there is a little screw on piece that has a screen in it which can clog up with fine particles of grit. unscrew it, if it's hard to get off use a pliers and put some tape around it to protect the finish if it matters. Run the water once it's off to be sure that was the problem then clean it and replace it.

Answer 5

I had the same problem. Some water heaters are better than others, although I do agree with one of the previous answers, it is important to insulate your pipes, you might have to go the other way on this and turn your water heater up a bit more, another solution would be to check under your sink, you have two knobs, one hot and one cold, make sure the hot is opened up all the way.

Answer 6

I am assuming that the showers are closer to the garage. if the kitchen faucet is more than 100 feet from the heater you need a recirculating line

Answer 7

We have the same problem and the plummer said it was because our kitchen was the room farthest away from the water heater, and it took awhile for the water to get hot to travel that far.
Now since our half bath is directly across from the kitchen(but same side as water heater) it gets hot water faster.....Go figure!

Answer 8

Sounds a little strange, unless you are not letting all the non heated water clear the lines, ( not letting it run long enough). You could add an electric hot water tank under the sink.

Answer 9

Medium high is best and the most safe. I'd look into a new faucet.

Answer 10

Make sure all the hot water lines are insulated.
