Rating of the TOP-12 best storage water heaters for 30 liters in 2024-2025

This rating includes the best electric storage water heaters in terms of quality and reliability.

How to choose a storage water heater?

When choosing a storage water heater, users are guided by its volume.

But there are other technical nuances that you should pay attention to before buying such a device:

• tank material. The container inside can be made of stainless steel or have an enamel coating. The first option is better, since stainless steel does not corrode and practically does not scale. Boilers with enamel coating are cheaper, but need regular maintenance and descaling.
• Heating element type. In storage water heaters, a dry or wet heating element can be installed. In the latter case, the heater is constantly in the water and works on the principle of a boiler. Dry heating elements are placed in special tanks, and therefore serve much longer.
• Hull shape. Cylindrical boilers are considered the cheapest, but even small 30-liter devices with a body of this shape will take up a lot of space in the room. If you need a more compact device, it is better to give preference to rectangular or flat water heaters.

Types of storage water heaters

All storage water heaters are divided into types not only according to the shape of the body or the inner coating of the tank, but also according to the type of placement. According to this criterion, boilers are of two types - vertical and horizontal.

The first type of device is more common. Such water heaters are inexpensive, easy to install and maintain, but take up free space in the room.

If you need to save space in the bathroom or in the kitchen, it is better to give preference to horizontal models. They can be installed under the ceiling, and the device itself will successfully heat the water without taking up much space in the room. But it should be borne in mind that such boilers are much more expensive than vertical ones, and it is much more difficult to install and maintain them.

Which firm to choose?

Since the water heater is used frequently and is constantly in contact with water, you should not save money and buy devices from little-known brands. It is better to give preference to products of well-known manufacturers, especially since you can find quite affordable devices in their lines.
