How to choose your electric water heater

The electric water heater is an extremely useful appliance that can be extremely energy intensive. This is why you must be careful when making your choice. To do so, you must consider the following parameters.

#1 - The needs

The first and foremost criterion to consider when choosing a water heater is its use. If you are looking for a device that satisfies the needs of a multi-person household, you should opt for a hot water tank with a capacity of around 100 L. On the other hand, if you are a single person or a couple, an instantaneous model will perfectly meet your expectations.

#2 - The type of device

You will have the choice between an instantaneous water heater and an electric cumulus. The former produces hot water on demand, while the latter takes longer to heat the water. On the other hand, the cumulus can store this water for a long time depending on the range of the device, which reduces its energy consumption.

#3 - Consumption

The energy consumption of a water heater is determined mainly by its technology. Generally speaking, instantaneous models have a reputation for being more energy intensive compared to hot water tanks. On the other hand, some instantaneous units have a heat pump and can be used in green mode. All in all, take some time to do some calculations before making your choice.

#4 - Security

Water heaters have a basic safety feature including a safety valve, a thermostat and a temperature indicator. Aside from these safety features, you need to consider the design of the unit, especially for storage tanks. Make sure that these have an anti-corrosion tank that guarantees the purity and conservation of water in optimal conditions.

#5 - Maintenance

If you choose an instantaneous water heater, you won't have to worry about maintenance, apart from descaling every two years. In fact, this type of appliance does not require any regular monitoring, although you should always remain vigilant. On the other hand, with a hot water tank, you will have to monitor certain aspects of the appliance, particularly the tank, which can accumulate scale and affect the purity of your water.

Hot water production: a question of common sense.

Hot water is an essential part of everyday life. However, its production is the subject of much debate, as it consumes a significant amount of energy. This expense has caused electric water heaters to come under fire from environmentalists, especially for instantaneous models.

However, if you know how to manage your consumption well by continuing to be masters and not slaves of these appliances, you can get the maximum benefit without harming the environmental balance. In short, if you want to adopt an electric water heater, don't deprive yourself. Just watch your consumption pattern.

The different types of electric water heaters

The electric water heaters currently available belong to two main families: the instantaneous models and the cumulus. Zoom in on the characteristics of these two appliances:

Electric instantaneous water heater

The instantaneous water heater is a small device that produces and delivers hot water directly. This type of device allows you to have hot water only when you need it. Also, if you know how to manage your needs in this matter, this type of device can be very economical.

The electric water heater is just as popular as the cumulus. Its dimensions make it a compact device that takes up very little space. If a T-bend is used, it can supply several points. The Ariston 3100854 and the Clage M 3 models belong to this first family of water heaters.

Electric cumulus

The cumulus is a device with a tank that stores water inside. The stored water is heated by an electric resistance or a heat transfer fluid. With this type of device, as soon as the container empties, cold water comes to fill the hot water tank.

The electric water heater (also called hot water tank or electric storage water heater) is a comfortable, economical and easy to use device. It is ideal for producing hot water in a home. The 100 L Aquamarin electric water heater and the De Dietrich 7605057 are in this category.

Electric or gas water heater?

Electric water heater

The electric water heater surpasses the gas model in terms of practicality. It is easy to install, does not require any draining device and can be placed anywhere in the house. On the other hand, you have to be careful with the humidity of the rooms. But the main disadvantage with this type of appliance is the use of electrical energy which is a problem at the moment.

Gas water heaters

The gas water heater is a more economical alternative because it requires little installation and almost no maintenance. This type of appliance consumes less energy than electric models. On the other hand, from an ecological point of view, it is a rather inefficient device, as it emits carbon dioxide during combustion. Finally, you will be limited in terms of location, as this model must be connected to the domestic gas network.

Verdict

It all depends on your needs and habits. The electric water heater is easier to install and requires less maintenance. If you know how to manage your consumption, this model will suit you perfectly. On the other hand, if you are afraid to overuse, choose the gas model. It is much more economical.

Tips

Set the temperature

Generally speaking, a temperature of 55 to 60°C is more than enough to obtain hot water at the ideal temperature. Also, if your appliance displays 75°, no need to go that high.

Switch off the appliance if you are away

If

you plan to be away for an extended period of time (vacation, weekend), disconnect the power to the water heater. However, keep the power on if you are going to be away for less than a day.

Install foamers

Foamers are devices installed on faucets. They help reduce water waste, and therefore, hot water.

Use the appliance during off-peak hours

If

you have the off-peak and on-peak options on your meter, use your electric water heater during off-peak hours to reduce your expenses

.

Choose showers over baths

Also

in order to reduce your electricity consumption, opt for showers because bathing requires a very large amount of water compared to showering
