Installing an electric water heater is essential to have hot water at all times. This device is essential in all homes. If you plan to buy some, you will have to be meticulous during your research. Indeed, it is not easy to sort out the countless models. During acquisition, consider the design, power, capacity and type of water heater.
In this buying guide for the best electric water heaters, it is recommended to look at the design of the device. This feature does not directly affect the performance of the device. However, it should not be neglected.
Each manufacturer tries to stand out by offering models with an original design. All brands bring their personal touch to the aesthetic aspect of their product. To make the right choice, choose the model that harmonizes with the room in which you are going to install the device. Whether on the shape or the color, choose the device that will easily integrate into the place.
In this buying guide you will find the best tips to make it easier to choose your water heater. Indeed, it is not always easy to decide since there are many parameters at play. Anyway, it is important to choose the power of the device you are going to buy.
This characteristic can reach 2000 to 3000 W depending on the capacity and performance of the device. If you are few in a home, it is not necessary to invest in a powerful device. Otherwise, choose powerful models to meet your hot water needs.
If you are still struggling to answer the question of how to buy a better value for money electric water heater, you will have to consider its capacity. This criterion varies a lot depending on the model you choose. Its choice depends essentially on the number of occupants and their consumption of hot water.
In general, an adult consumes an average of 50 liters of water per day. It will therefore be necessary to choose the capacity according to this simple calculation. By considering the needs of all family members, you won’t run out of hot water. Indeed, it is not really pleasant to take a shower with cold water, because the device does not produce enough hot water for all the occupants of the house.
If you still don’t know where to buy a new electric water heater, you need to figure out what kind of appliance you need. Once you have the answer to this question, you can easily find the right equipment for your needs.
If you want to acquire a tankless device, then the instantaneous water heater will do the trick. This device heats the water according to your request. On the other hand, models with balloon make it possible to store hot water that is maintained at temperature.
After making your choice among these different types of devices, you can finally go through a price comparator. This step is essential if you want to get a good deal.
How to use an electric water heater?
The water heater has become an indispensable household equipment in France. An adult consumes on average about 80 liters of hot water at 40°C per day. There are several types of water heaters on the market, certainly, but it is also important to know how to use these devices wisely.
What are the elements that make up a water heater?
Let’s start by understanding the system and elements of a water heater that produce hot water at any time of the day. In fact, it is a very simple system. A water heater includes an enamelled tank with a capacity of 150 to 300 liters of cold water, a resistor, a heating system to preheat the water, a regulating thermostat that measures the right temperature, another system to prevent corrosion. A timer is also incorporated into some appliances in order to use a water heater wisely.
What are the functions of an electric water heater?
The two main functions of a water heater are to heat water and store it in case of non-use. It is best to heat the water at night or during off-peak hours (from 5am to 7am or from 4pm to 6pm). Program the warm-up time using a timer. This limits your electricity consumption and avoids a very high energy resource use during the peak hour of the day. Especially since the excessive temperature of the water stored inside could quickly damage the pipes of your device.
Reinforce the insulation of the tank of your tank to keep the water at the right temperature as long as possible for optimal use during the day. The ideal temperature for a comfortable shower is 40° to 50°C. Beyond this temperature, you will burn yourself. So mixing hot water, naturally lighter, and cold water is very important.
Some useful tips for maintaining your water heater
The resistor that is in direct contact with the water in the tank of the device may scale. Thus, it is necessary to systematically clean the limescale residue that forms on it and which would certainly decrease the effectiveness of the resistance. You may no longer get hot water if it is not descaled regularly.
Install a jet breaker in the tank of your water heater. This technique will help you preserve the distribution of water according to its temperature. Limit the flow and pressure of your faucet or shower to reduce your need for hot water. By doing so, you will save consumption not only in terms of water but also electricity.
And finally, get into the habit of unplugging the water heater when you have to be away on weekends or spend a week of family vacation by the sea.
What to do if the water heater leaks?
At some point, the water heater will start leaking drip by drop or in larger quantities, which won’t alarm you much. If this happens, however, precautions should be taken as soon as possible. Over time, this type of problem causes much more than a trace of rust inside and outside the device. But to make repairs, you need to know the source.
Determine the leak and find the right solution
This device is primarily connected to a cold water source and returns hot water to various facilities such as the sink in the kitchen, the shower or the bathtub. Water heater leaks can come from anywhere: perhaps from a poorly done installation or a worn part. Each case requires separate treatment, which is why it is necessary to determine precisely where the flow results from. Of course, this kind of complication is avoided by, for example, replacing the safety group every 5 years, but also by maintaining the device regularly. Here are the different leaks on a water heater (here are our best examples).
Flow from the bottom of the tank
This is one of the most serious cases for a water heater. A crack is certainly located in a certain place in the tank and this is usually caused by corrosion caused by very calcareous water. An easily recognizable rust color often mixes with the traces.
If this happens in just 10 years after the device was purchased, it means that there has been a lack of maintenance. In this case, no repair can solve the problem. A new device would then have to be procured. Calling a professional for the replacement of the tank is necessary, but it would be about the same price as a new device.
At the level of the fittings
It goes without saying that an appliance of this type must be connected to several elements of the plumbing. We talk for example about the arrival of cold water, the outlet and many others. Each component connects to specific locations. These points are the most sensitive throughout the installation. The joints have flaws that grow over time. The rate of deterioration increases especially when using a water softener. Improper assembly can also lead to dripping at these levels.
They must therefore be checked regularly to ensure that no leaks occur. If there are any, start by tightening bolts and other screw thread parts. If that doesn’t work, consider replacing the gasket or entire fitting. In addition, using a special glue helps solve a small problem.
On the security group
This usually happens during heating. Also be aware that this is the only leak that can be considered normal for a water heater. The pressure in the tank increases by 3% to 5% and the non-extendable flask causes a small loss. The net evacuation of the excess is then done at the level of the safety group. A receiving hose is located here to collect the drops, thus preventing the degradation of the other components.
Remember that this flow lasts only 30 minutes, after the heating cycle is complete. The flow in quantity occurs at the safety valve, only when the device is put into operation.
Continual leak of the security group
In general, this part should only let out small drops. However, sometimes it is found that the amount of water lost becomes too great. This may be due to persistent runoff driven by a faulty safety group, requiring the intervention of a repairer. The problem also stems from residue stuck under the valve seat. In this case, limescale accumulates in the duct. To fix this, abruptly open the valve lever and wait for there to be a slam. Otherwise, this case also results from a high cold water pressure, i.e. greater than 7 bar. Simply install a reducer at the outlet of the water meter to prevent it.
At the flange
This leak always occurs at the hood. The probable cause in this case is the defective joint of the flange. In general, this happens after a descaling of the resistance. Poorly closed or worn seals allow water to pass through. Before carrying out the repair, remember to empty the tank completely. Then tighten the fittings and check if there is still a flow. If this happens, disassemble the resistor and replace it. In case you still notice drops, call a professional to determine exactly the problem and fix it.
Have the device professionally diagnosed
In some cases, the owner’s intervention is not sufficient or the owner does not have enough time to make the repairs himself. It is then necessary to call a professional to diagnose and recap the water heater. He will draw up an estimate allowing to know the amount of repairs according to the seriousness of the case. Thanks to this, you will be able to know more precisely the cost that troubleshooting will generate, for labor or for the parts to be purchased, necessary for the product.
To date, many specialized sites offer free quotes. All you have to do is visit their platform, then fill out a detailed information sheet, to determine the source of the concern and the price according to it. This type of process avoids travel. This is why many individuals use it. Faced with the daily obligations, few people have the time to personally take care of their water heater, even if the damage is minimal.
Know that it is necessary to work on the problem as soon as it is noticed in order to prevent it from getting worse. Indeed, water damage is increasingly difficult to treat as time passes. In addition, it will require more effort and cost more.
Savez-vous comment entretenir votre chauffe-eau électrique ?
The maintenance steps of an electric water heater do not present any difficulty that even you, you can learn the processes without calling a professional. It will only take you a few minutes especially if you have the appropriate equipment. In addition, be sure to take care of your equipment in order to benefit from optimal performance, but also to avoid a complete increase in your electricity bill.
If you get into the habit of maintaining your equipment, he can accompany you for years in your home. Also, it is recommended to drain its contents once a month, often twice for regions where the water has a high level of limescale. You’re probably wondering why you need to perform the purge process regularly. This will allow you to remove sediment and limit its deposition on resistance. This operation also determines the life of the tank while optimizing the performance of your equipment to reduce its energy consumption.
The procedure to follow is simple, without you having to contact outside help. Beforehand, you must turn off the power and close the shut-off valve on the safety group. Activate the bleed lever and open a hot water faucet. Let the water run into the siphon, being careful not to touch it. Once the tank is emptied, all you have to do is turn off the drain valve and restart its supply.
Spot anomalies and equip yourself
An electric water heater (here is our list of the best products) requires a descaling operation at least once every 3 to 5 years, and more for homes in very calcareous regions. The anode must be checked once a year and the safety group is to be replaced after a maximum of 5 years. If you notice that your device takes time to heat up or that it has a rather annoying acoustic frequency during its operation, you will know that it is time to move on to its maintenance. It is based on your DIY performance that you should or should not call an expert in the field.
Before starting any action on your cumulus, you must bring some practical accessories. For this, there is no need to take the arsenal out of your toolbox. You must have nearby a socket wrench for the various screws located on the device, a pair of rubber gloves to avoid direct contact with sediment and a paper towel or brass wire brush in case of significant scaling on the anode.
To proceed with the actual descaling, you must initially turn off the power to your cumulus. Drain the tank so you can easily reach the water heater components. To speed up the purge, you can always turn on a faucet in the house. Via the socket wrench, unscrew the hatch to have direct access to the electrical box and thermostat. To disassemble the latter, you just have to pull it down.
Bring a cloth or paper towel for cleaning the bowl and rubber gloves. Check the status of the resistor. If limescale is in large quantities, gently rub the anode with the brass wire brush. This component and the seal can be replaced if you find that they are no longer operational. Don’t forget to inspect the compatibility of spare parts. If in doubt, you can always call a professional. Once these steps are completed, all you have to do is put your hot water tank back in place by performing the processes in the opposite direction.
Maintain your equipment even in case of absence
If you plan to leave your home for a few days or even weeks, it’s best to turn off power to your equipment. This will allow you to maintain it even if you are not at home. Indeed, when you turn it off, it will avoid heating the water unnecessarily since no one will activate it. In addition, it will have less impact on its energy consumption.
In the case of a second home, it is better to drain the tank completely. The tank is completely corrosion and wear proof. There is therefore no risk of the equipment malfunctioning when you restart it. However, on some models you will only have to set the performance of your equipment by activating the “away” mode. This option limits energy expenses without any intervention on your part, thus preserving your electricity bill.
The most popular brands
The electric water heater is an essential step to have hot water at home at all times. This is if we can say the basis of all modern living comforts. Then, as for the choice of energy to use, gas, current, solar energy, everyone has his preference.
