Sounds like you need a new Thermo coupler.
Could be as simple as a dirty pilot and needs cleaning but I suspect a thermo coupler.

Can I turn my water hotness up


Yes is the simple answer, If you have a gas water heater then the stat (thermostat) is located right at the front of the water heater and has heat gauge levels plus it should say Very Hot- Hot- ETC.

On the Electric water heater there are two doors on the face of the water heater and they are held by two screws-take them out and there should be a stat that has temp settings on it, you may have to pull a little insulation out of the way. http://www.water-heater-repair-guide.com/waterheaterthermostat.html

I have 2000 astro van and I'm not getting heat, I changed thermo stat and flushed heater core. Still no heat, whats the next step?


Feel your heater hoses. If both are hot, the core is circulating. If only one is hot-poor or no circulation of the core.
If the heater core is circulating, the temperature blend door may not be working to let blower air pass across the heater core, and into the vents. If vacuum operated, watch the vacuum valves as you move heater controls-you may spot the problem. Check that the vacuum line from the engine to the control switch is working and still connected. If not operated by vacuum, the controls may have cables to the heater case or may be electrically operated. You'll just have to scope it out. Good luck.

Car heaters not very hot


try changing the thermostat and make sure all the air is bled out of the system this should help your heat problem.before changing the stat with the motor at operating temperature grab the heater hoses to see if they are the same temperature or not.if they are the same then change the stat.if not the same temp then the heater core may be plugged or partially plugged and will have to be changed.still change the stat as they do get tired and won`t work properly.

I have a 2000 nissan xterra my heat dont warm up i change my thermo stat if i get my heater core flush what are my chances of it working what are the major problem with the 2000 nissan xterra i done...


forget all the above items you mentiond,the heater metrick/core should be ok if you put a cooler flush through the system,im looking at the thermo switch mounted on the top of the water system it will have two wires on it and tells the engine when to let hot water through the core,also if its not working the engine will not perform great so try this and forget about new spark plugs/wires/coil pack ,as these are nothing to do with heating.adrian,,,

Do you have a pic. of how i hook thermo to my marley 72 inch baseboard heater , i have the mdl. fta1a the instructions show line 1 and 2 , but i have two wires on the left front that are hooked to the...


Two wires to the T-stat should go to W and C which is W for heat call and C represents common!
When the T-stat is set to heat it will connect the 24v red wire to the W terminal therfore sending 24v to the heater and the common wire completes that circuit. Make sure to use an inline fused wire to test so you do not blow your transformer. Easier to replace a fuse then a T-form

Hot water does not last long. Model 82vh40-2 mnf. 05/2005


If the lower heating element burns out the upper element will heat the top part of the tank then shutoff. homw depot/lowes etc should carry elements. 1 turn off breaker, remove element access cover (the 2 panels on the front of the heater) test for electricity at the reset button ( uppermost device in upper panel) to make sure power is off. 2 turn off water (I usually turn off the cold water main to stop water cross feeding into hot supply line back into heater) 3 disconnect the 2 wires on the lower element, test with continuity tester. shhould be no continuity between terminals and tank, but around 10 ohms between the 2 terminals. Check the thermostat for continuity if tank is cold thermostat should be closed ie zero ohms across the 2 terminals.
If stat is bad replace stat; disconnect wires push it up out of the spring clip insert new stat reconnect. If element is bad: drain tank. connect garden hose to tank drain valve, open tank drain valve turn water main on to clear rust sediment and get water flowing. Next remove filter screen from a hot water faucet then turn on ( a hot faucet upstairs or higher than tank drain). Now turn water main off, air will now go in through hot faucet and tank will drain, takes about an hour. Use a water heater element wrench about$10 to remove element(s) make sure no bits of rubber gasket are left in element opening- dig em out with a screwdriver if needed. Insert new element with its gasket and tighten. reconnect wires DO NOT TURN ON ELECTRICITY! BE SURE TO FILL WATER HEATER WITH WATER ! Turn water main back on -air will come out of the hot faucet for several minutes. When water runs without any air sputtering, turn off faucet and replace the faucet filter screen. check element(s) for leaks. turn breaker back on.

Bradford White Water Heater Model: M165R6DS13


Immediately turn off power to heater. One of two things has happened. Either: A. The electrical contacts in one of the thermostats has welded together, necessitating replacement of the thermostat(s). (in this case I would recommend replacing both upper and lower thermos) or B. The lower element has burnt through, and because there is 120 volts to the lower element at all times (it normally only heats when the thermos complete the circuit to give it a path to the other "hot", putting a full 240 volts on it) a section of the element will continue to heat up to the point where the break allows the current to complete it's path to neutral ground via the water in the tank. It can continue to heat until the high limit safety thermo trips out. (the red reset button on the upper thermostat)
If either condition exists, the high limit safety thermo should trip out power to the heater before boiling water, and thus steam, is produced. Even if the safety thermo should fail to cut power, the pressure / temperature relief valve should open, releasing excessive pressure. If that should also fail to open, due to corrosion or such, the water heater will create steam and can actually result in explosion, and possible injury or death!
Several years ago I came across one that was boiling and when I turned on a hot water faucet to relieve the pressure it filled the entire basement with steam. (I still shutter to think if I didn't catch that fast enough I or someone else could have been killed)

The most likely cause of your extra hot water is actually the lower element. After you turn off power to the heater, turn off the water supply to the heater, open a hot water faucet to allow air to enter the tank and drain the tank. Remove the lower element. A bad element is usually visually apparent. If it looks good, you would have to test it with an ohm meter. (should be about 20 ohms if it is good) Install new element, turn on water and fill until water flows steadily from the hot water faucet you left open. Now you can turn the faucet off and turn power back on to heater.
