Shopping guide

Housing and dimensions

In any comparison of water heaters, you will find two attributes of great relevance and interest for any buyer, this being the case of the material of the casing and its dimensions.

The most popular materials in the industry are polymers since they provide the design with a high level of resistance, stability and soft touch when handling them. Polyvinyl chloride or PVC is a good example of this, also characterized as a good insulator, so it is even used as a coating on aluminum models. Also, some equipment that annexes a water reservoir employs an enameling technique to prevent corrosion.

Regarding the issue of dimensions, you will have to be careful so that you avoid inconveniences when assembling. In this sense, it is necessary to verify that its height, width, and background are appropriate to the selected space. In general, the designs are quite compact, with measurements ranging between 20.5 x 33 x 55 and 70 x 35 x 26 centimeters, these being only some outstanding measures.

Security and cleaning

Depending on the selected design, the security aspects to be evaluated may vary. For example, in models that work with gas, you will have to make sure that the connections of the hoses adjust correctly, to avoid any type of leak that leads to an unexpected accident.

The electrical equipment must incorporate a protection system for overheating and, if possible, a regulator for the temperature, which allows you to adjust it to a specific level. In addition, it is convenient that you confirm that the AC input is compatible with the power source in which you plug them. This way you can avoid the deterioration of the useful life of the motor, the resistances or coil.

On the other hand, we have the cleaning method. According to the specifications of each manufacturer, commonly exposed in the instruction manual, you can clean the outside with a soft sponge moistened with detergent or water, thus eliminating dirt. What you can not forget is to dry it with a cloth to prevent the proliferation of mold or bacteria.

Accessories

When acquiring a water heater, we must verify if the manufacturer incorporated some accessories with the purchase, since this will help you to improve your user experience. In general, a pair of supports, metal hooks or base with its respective set of screws are added to the package.

In this sense, you will have everything you need to properly fix the structure on the wall. Also, there are those who annex the electrical connection cables, hoses, and valves, for that equipment that work with gas. Also, a manual shower, among others.

It is important to keep in mind that in some cases this could influence how much the product costs, but definitely in the long run it will be much more favorable than buying separately each of the elements necessary to carry out the installation. This way you will enjoy a correct and safe operation by the device.

Functioning

There are many quality identifiers to evaluate when it comes to a water heater, one of them being its operation. And it is that, although when verifying the aforementioned elements you conclude that it is a good and economic team, this will not be relevant if its implementation and work methods are not intuitive.

Therefore, you must ensure that the selected device has a control panel with properly identified switches, thus allowing correct handling at all times and by any member of the family. Also, it would be convenient to incorporate a small LCD screen, so you can monitor the level of temperature acquired by water.
