Hot Water Question

I'm hoping someone can help me with my hot water issue. I turn on my hot water heater, after it heats up I turn on the hot water faucets and get a little hot water and then its all cold. I thought I had the valves turned off but in checking them they are all open. Is there something I'm missing??

What type of water heater are you using: Tankless or Tank?

If tankless, these are NOTORIOUS for giving poor hot water flow (see the NUMEROUS threads on this site about that).

If tank, are you POSITIVE you're not bypassing the water heater? In our old 365BHS (tank style), it was VERY EASY to bypass the water heater (simple valve positions on the control panel) for winterization. If you're bypassing, MAKE SURE YOU DON'T RUN THE WATER HEATER. You'll overheat the system without water in the tank - VERY important.

Does the little hot water feel really hot, just a bit warm, warm? On the back side of the WH you have a cold coming in and a hot going out( both valves open). Between the 2 lines you have another line and valve connecting the 2 and that one should be closed. The layout should look like an (H) on its side.

Im sure the valves are open and there is water in the tank. I turned the valves and heard the water fill the tank...plus the little bit of water I do get is really hot. I thought at first I needed to run the hot water for a while to fill the pipes but after 10-15 min of running it still ran cold. I also thought that I had the middle valve closed (between the hot/cold coming out of the WH) when I closed it water stopped flowing out of the faucets....that's why I am confused.

It sounds like you have the valves set incorrectly. there should be 3 valves and it sounds like you've identified the bypass valve (the center one) That one must be closed and the other 2 must be open. Usually the "OFF" position will have the handle at a right angle to the water line. With the center valve off and no water check the other 2 valves, make sure they are open. Maybe the valve handles are mounted incorrectly.
