Question about Stiebel Eltron TEMPRA 24 Tankless Water Heater

1 Answer

The heating element continues to heat even after the hot water tap is turned off thus popping the thermal switch. The red light is off on front of unit but you can hear the water heating. Any ideas?

Unit should not continue to heat water after hot water tap turned off. After several seconds it gets too hot and pops the thermal switch. Any remedies or thoughts on why this is happening would be appreciated.

Check the pressure control that switches the element on or off
if it is faulty then it switches on when the tap is turned on dropping the pressure but it will not recognize that the increase in pressure when the tap is turned off so it keeps heating the water.

The paid answerers may have a person who knows your product and the problems associated with your model.

I only see the questions where people have not paid.
Each day I see 20-25 unanswered questions about tankless water heaters.
And the day before, the same number of unanswered questions about tankless products.
The number of questions shows the complexity of the machines, and the inability of the manufactures to take care of their customers.
The manufacturer will refer you to the installer.

There are not many ways a do-it-yourselfer can fix a tankless.
In contrast with tankless, tank-type water heaters have generic troubleshoot steps that lead to a quick diagnosis, and same-day repair of almost any brand. Most times a tank-type heater repair can be DIY.

This will be a thermostat or element problem. The red light tells us that you have power to the unit. If you are handy you can test the thermostat and the element with a continuity tester. A voltmeter may also be used. This will tell you where the fault lies.

SOURCE: stiebel eltron 12 the thermal breaker keeps

Hello; I can't clain any formal training or education in electrical, But, I am a home owner and Mechanic so I'll give this a try. Thermal switches are in the norm based on the bi- metal concept/ Automotive flashers are in essence thermal switches. Of course there are electronic types that contain points and a coil, we can forget those since we aren't doing a car or truck, let alone turn signal. OK, moving on. As you know,excessive continuous heat generated by a excess load will destroy the bi-metal strip which serves as a bridge in the circuit. A defective flasher will increase in speed as it gets older and used heavily. Anyway, to the point. I've experience thermal switches that cease to function if trip too often or were tripped by an excessive load. Although resettable initially, it's thermal tolerance gets shorter and shorter until eventually you get irritated enough to ask someone on Fix-ya for some input. No problem. I reccommend replacing the breaker with or of same amperes. You may want to verify the load by checking the appliance data plate just in case it's the straw the breaks the circuit I hope I helped you and I apologize for the analogy used. Thanks for using fix-ya. Good Luck _Ned_t

Why when I turn the hot taps on I get milky water out of the hot taps and its a new HWS Vulcan 250 lit electric single element only 3 months old


Put that water in a glass and let it sit for a couple of hours. If it clears up, it is air bubbles. The old unit most likely had mineral deposits on the elements and they insulated the water from micro heating that creates the bubble. Since the unit is new, the water is in direct contact with the heating elements and micro bubbles are forming on the elements. When you turn the hot water on, the turbulence washes the bubbles out.

Question posted under Bosch tankless.
Question says 'tank'
Brand, model, and type heater unknown.
Elements mean electric.
'Thermal cutout pops when taking shower produces cold water' indicates tankless, since tank-type would maintain some hot water.
No error code might indicate tank-type.
Add a comment with type, brand and model number of heater for possible assistance.

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.

The water gets too hot and trips the reset on the thermostat.


Two possibilities. 1 failed upper or lower Tstat 2 Shorted element
To test element: disconnect both wires to element terminals. use continuity tester to see if there is continuity through element (one probe on each element terminal) If no continuity element is bad. Then test for continuity between each element terminal and the water heater itself.( one probe on element terminal and one probe grounded on bare metal or inner tank.) If there is continuity from terminal to ground, element is bad and also can cause tank to continue heating even when thermostat shuts off. This is because the thermostat only shuts off one pole of the 220 and a shorted element can continue heating from the 2nd pole.
If both elements test OK and water heater heats the full tank( tank feels hot at bottom element access panel when no hot water for 2 hours) most likely the lower thermostat is bad.

Take off front cover, on the top of the two cylinders in there (the heating system) there will be a small red button. That is the Safety Thermal Cut out, depress that red button. It is similar to a circuit breaker. If the red LED comes on when you turn on hot water at a sink then that was the problem. I have on that trips periodically. Its annoying but not enough to replace the part yet. Good luck.

Bosch PowerStar125 won't heat and I can't get one element to work


It sounds like you have a copper canister unit. Ohm out the elements in that one canister. the directions are on the websight for bosch, or I can walk you through it. But you will need a digital multimeter to do this. If you have a blown element in that one canister, then the tco will not reset.
