My hot water tank no longer heats up: what to do

To start, make a very simple verification by ensuring that your home is well supplied with water.

Why my water heater no longer heats ?

You can see a temperature breakdown On your water heater, while on. If your device no longer heats up or no longer works as before, you will have to test certain elements likely to be responsible for this problem:

Check that thewater supply is always assured;
Check that the security is not engaged;
Test it thermostat;
Check that your tank does not need descaling;
Test it resistance of your water heater, which transforms electrical energy into thermal energy.

These checks and tests should provide an answer to your water heater problem, hot water tank or cumulus.

1 Check that the water supply is always ensured

To start, make a very simple verification by ensuring that your home is well supplied with water.

Open a hot water tap:

If there is no more water flowing, Check that your water is not cut. If you notice that your water supply tap is open and that there is still no water at home then, you will have to have your installation checked by a plumber.
If water flows, but it is not hot, So the breakdown is rather linked to your water heater or hot water tank.

2 Check that security is not triggered

If your thermostat is disarmed or poorly adjusted, your water heater (or hot water tank) will no longer be able to heat the water.

Cut the current.
Remove the cover of your water heater using a screwdriver or declip it.
Locate a Red button on your thermostat And try to drive it using a flat screwdriver or with your hand: you should hear a “click”.

If the red button was not sunk, safety was activated and that is the cause of your problem. It can happen if there has been overheating or storm.

The thermostat is one of the most important elements of the water heater, because it is he who regulates the temperature. To test the thermostat:

First check that your water heater is out of course: you must put the circuit breaker and the switch to 0.
Adjust your multimeter on continuity mode, represented by a sound wave icon.
Remove the cover of your water heater and locate the thermostat.
Put the key tips of the multimeter in contact with the thermostat. Repeat the same operation for other contact points.
If your multimeter posted 1 or ol, So the electric current does not pass: your thermostat does not work and it must be replaced.

If you are equipped with a Stean resistance, It will be necessary to proceed:

Disconnect the probe cable which is connected to the thermostat
Disconnect the cable from the probe related to electronics.
Remove your fuse, then using your multimeter, check that your fuse works by carrying out a continuity test.

If your water heater does not work, descaling can provide a response to the temperature problem. To check this, we will have to dismantle the device.

Cut the water supply.
Put a bowl under the tank and activate the valve located on the safety block of the water heater. This will open up the safety block valve and evacuate the water by the siphon.
Once the water from the tank is emptied, remove the hood from your water heater.
Disconnect and remove your thermostat.
Disconnect the cable from the probe linked to electronics and remove the probe.
Put a bowl under the tank to accommodate tartar.
Disassemble the flange if you have welded resistance then remove the block to clean the tartar.

Resistance is a part located inside the tank. It makes it possible to transform electrical energy into thermal energy, to transform electricity into heat to heat the tank. You can have a armored resistance, that we can see directly when the block is removed, and a Stean resistance, inside a scabbard.

To check if your resistance works, you must disassemble your tank and make a drain.

If you have a armored resistance : adjust your multimeter on continuity mode, disconnect and remove your thermostat, then place the key tips from the multimeter at the resistance terminals.
If you have a Stean resistance, Place the multimeter tips on the metal of the resistance.

If the multimeter displays 1 or ol, then the resistance is faulty and it will be necessary to change it.

More hot water with cumulus ? Start by identifying the origin of the breakdown

A hot shower in the morning is ideal for starting the day. However, this privileged moment can quickly turn into a real test when the cumulus does not heat up and you no longer have domestic hot water.

The operation of the hot water tank must be mastered to provide the right answer to each problem. You have a gas boiler and a hot water tank. Your heating works, but you have a broken hot water tank? You should know that the operation of your cumulus is independent of your gas boiler.

In such a situation, the first reflex is to find a solution in order to get hot water or a correct hot water temperature again. However, the gestures to be undertaken depend on the origin of the problem. At first, it is therefore necessary to identify it.
- The breakdown may come from a Plumbing problem. To be fixed, try to open a hot water tap. If the water does not flow or if the flow is extremely low, this is a problem in the plumbing. The intervention of a professional plumber will then be necessary.
- In some cases, it may be a problem related to your equipment. A poorly adjusted or broken thermostat, a defective resistance, a scaled water heater may be the cause.
- You can also face a Electric problem. Electricity supply may be cut. Check the electrical circuit breaker. Electricity supply must come from the general table. If you are a handyman, use a multimeter in the thermostat to find out if there is current.
Balloon that does not heat: how to solve an electrical failure ?

To make sure the breakdown is of electrical original, open a hot water tap. The flowing water is cold or lukewarm? It is certain, you no longer get hot water from your water heater because of an electric breakdown.

If you have identified such a problem, you must make a point:
- Make sure your water heater is properly connected to an energy source. Go to the table if the power supply has not been cut by the circuit breaker.
- If you use a programmer, check that it is well in working order, or put your water tank forced to have hot water.
- Also examine the circuit breaker as well as the fuse dedicated to your hot water tank. It may have been a short circuit.
You have a multimeter and you know how to use it, test the voltage under the circuit breaker and under the thermostat to be fixed.

What if the hot water tank does not heat because of a defective resistance or thermostat ?

Your cumulus does not make hot water ? It may be the failure of the thermostat or the resistance.

The thermostat is disarmed

If the thermostat is disarmed, just put it back in working order so that your water heater works properly.

First, you must open the low cover of your cumulus. Then press the rearmament button (the red button) to restore the thermostat.

The thermostat is poorly set

If you no longer get hot water from your cumulus, the problem can also be due:
- to a badly adjusted thermostat
- Too high temperature adjustment.
In order to remedy it, you just have to reduce the temperature.

The problem persists after solving the temperature ? The thermostat may be defective.

The thermostat is out of service

If the thermostat is faulty, you must replace it. This element is not expensive. In addition, it takes a short time to change the thermostat.

Resistance is defective

Your hot water tank does not heat. However, the thermostat and the electrical installation work properly. The breakdown surely comes from the resistance. In this case, it must be replaced.

However, the price of resistance often exceeds half that of a water heater. If your equipment is already older, consider replacing it. In this way, you will get an optimal lifespan again. Note that a cumulus has a sustainability of 10 years on average.

On the other hand, the price of the work will be lower. Indeed, replacing a water heater is easier than installing a new resistance.

My water heater does not heat because of tartar: what to do ?

Over the years, tartar accumulates in the tank of your water heater. If you live in a region where water is very limestone, this phenomenon tends to accelerate.

It is normal that your cumulus does not heat when the resistance is tarted. Indeed, tartar causes the resistance to obstruct. After a while, your cumulus will no longer even provide hot water.

In addition, limestone that accumulates at the bottom of the tank of your hot water tank can create cracks. You will then see leaks that may increase your water consumption.

It is therefore advisable to describe your cumulus. You can drain yourself. To do this, proceed in stages:
- Start by cutting the current and the water.
- Put your circuit breaker in a closed position, or remove the fuse from your water heater
- Close the water tap that allows you to feed your accommodation.
- Open the hot water taps in your home to completely empty the water heater tank.
- Once the tank is empty, open the tank and unplug the thermostat.
- Unscrew the nuts and remove the plate.
- Describe the tank by removing the limestone accumulated there using a sponge.
- Finish by passing a cloth on the walls of the device.
Also remember to clean the seal and its location. Before putting it in place, examine it to detect the presence of cracks. If you find them, you will have to replace the seal.

You can also clean the resistance. To do this, use a sponge or a brush with flexible hair brass wires.

The emptying must be carried out at least once every two years. However, do not hesitate to do it when you notice that the water is barely hot. Besides, the tartar that blocks the operation of the resistance can cause overheating. This is likely to damage the thermostat and have your installation disjurrent.

Water heater problem, more hot water: always check the circuit breaker

Sometimes your cumulus does not heat water for a simple reason: the circuit breaker jumped. Indeed, a water heater consumes a lot of energy. In this case, the circuit breaker can jump. The cumulus then ceases to operate.

So remember to check the electricity supply of your meter before any other maneuver. Make sure the installation has not jumped or that the fuse is not to be grilled.

If you use a day-night contactor that works on off-peak and full hours do a test.

Trigger your electric water heater during off-peak hours, put it in forced walking position on your contactor. The consumption displayed by your meter does not increase ? Your water heater is surely defective.

If the circuit breaker jumps again after you have given it, you must check your electrical circuits. A water leak may have caused a short circuit.

Why my hot water tank does not heat ?

In a hurry to take a good bath, you open the hot water tap wide. But after a few minutes of waiting, the bottom of the bathtub is cold and your hopes of relaxation collapse. This is what you are going through at the moment ? THE water heater problems are never a pleasure game. Rest assured, most often they are quite easily settled. Identify together, which can be the source of the absence of hot water in a balloon.

Cold water or lack of heat ?

The first point to assess is whether thewater does not heat at all inside the ball, or just not enough. Check the heat in the morning, when the temperature is normally the hottest. If the water from the house is still lukewarm, it is probably not the heating action that is involved, but a problem that prevents water from reaching its maximum temperature. Several repair tracks can be envisaged, some simple to check, others will require the intervention of a Professional plumber (Evaluate prices by asking for a quote), unless you are a plumbing handyman.

New water heater that does not heat up enough

If your water heater is new, it should naturally work perfectly and produce hot water. When this is not the case, check these few points:
- Is the water heater installed in a good position ? If it is a horizontal model, it will not work properly in vertical.
- Have you got correctly adjusted the thermostat ? A small wheel located under the balloon allows you to increase the temperature. On the other hand, the new models of water heaters do not exceed 60 ° / 70 ° C, where the ancients reached 80 ° C, so this can surprise you.
- Monitor the lack of a return of cold water, if work has been undertaken on the neighboring taps. To do this, cut the cold water supply to the balloon, then open the nearest hot water tap. If you notice that cold water is coming, even a minimum, it is that a equipment is defaulting, you will have to identify it and replace it.
- Place it En forced water heater for at least 7 hours. If the water is very hot in this position, it is that there is a concern for operating the day/night contactor. In this case, the balloon is not fueled into energy enough to heat the whole tank. Identify the problem or replace the switch.
Old water heater which no longer heats up normally

When a water heater is old, the above-mentioned points can also be involved. Added to this, the problems related to the age of the installation:
- Resistance or tank limestone.
- Hardware failure : resistance or thermostat.
- Thermostat safety : check this by cutting the power supply of the water heater. After disassembling the lower hood, you will see a small slot on the thermostat. Try to drive the interior button using a small flat screwdriver. If this one sinks, it is that the cumulus was in Safety mode. This can happen in case of overheating, power cut or storm. Watch after re-ending, if this happens, a Thermostat dysfunction is likely, as much as a significant fouling of the apparatus by limestone.
Water and electricity supply of the hot water tank

Naturally fearing the worst, we tend not to always check first, the essential points in Balloon heating. This is obviously the water supply, but also the correct power supply of the device. These few questions must quickly find an answer, before any other intervention.
- The general circuit breaker of the house, or that linked to the cumulus did not jump ? If this is the case, put it back in place, its reactivation indicates a electrical energy. It can be a short circuit linked to a water leak or the malfunction of one of the components.
- The fuse is not grilled ? Replace it and you should find a normal water heater.
- Is there water in the tank ? Does this one fill well ? Open a hot water tap, if nothing comes out or if the pressure and flow are tiny, There is obviously a Plumbing problem. If no water supply valve has been closed by mistake, you will have to worry about why water does not come to the ball and make the repair on the element implicated.
- Do you have alert messages ? Light diodes or error codes depending on the models. Refer to the instructions for your water heater to identify the failure activating the error.
Harvesting water heater or hardware failure

Tartar is at the origin of many water heaters. This is gradually installed inside the tank and on the heating organs. THE water flow and the temperature decreases. Normally, a Regular maintenance of the water heater of the house, made every two years, avoids this kind of misadventures, but also the repair price.
Recent models are equipped with an anode, in order to Limit limestone misdeeds. This stem can take different materials to operate:
- A Magnesium anode Removing the ions by dissolution, the latter preventing the installation of limestone on the heating organs. It is therefore necessary to replace it, every 4.5 years approximately.
- L’imposed current anode (in titanium) uses electrical voltage to capture minerals in water and force them to hang on the side walls, rather than on the central system. This type of anode is particularly effective on hard waters.
- L’hybrid anode groups the two previous processes for maximum efficiency.
Despite everything, the level of tartar ends up invading the cumulus and if no recent maintenance has been carried out, it probably explains the lack of hot water. Resistance, even if it still works, can no longer heat properly if it is covered with limestone. Ultimately overheating could activate the security group.
You can drain the water heater, After cutting the electricity to the circuit breaker. Then disassemble the underside in order to Clean the tank, resistance and anode. At this level, if you do not feel capable, do Make a quote to a professional plumber, To find out the maintenance price or repair of the hot water system.
Once the cleaning is done, take advantage of it to check the proper functioning of the organs using a multimeter. This, in order to immediately learn about a breakdown. In this case, it will be necessary proceed with the identical replacement of the part concerned.

Boiler problem: hot water failure

In the particular case of boiler, maintenance and repair must necessarily be engaged by heating professionals. These can be damaged parts or covered with tartar in the tank. It is likely that your boiler makes an alert message appear.
The burner is to be checked, it mixes gas or fuel oil and boiler oxygen to ensure good combustion. In the case of poor setting, the fuel mixture (gas/fuel oil) and comburant (oxygen) will not be or bad.
The nozzle, sends flammable energy towards the spark, to initiate the heating flame. In case of fouling, it will not work where the absence of hot water.
