Best 80-Liter Water Heaters with "Dry" Heating Elements

Chinese company Midea is known as a famous manufacturer of air conditioners and other household appliances. One of the brand's sources of revenue comes from storage water heaters. In particular, the 80-liter D 15F6(D) boiler enjoys popularity among the public.

The water heater is assembled in a narrow, tall body: it is 38.5 cm in diameter and 103 cm in height. The device occupies little space in the corner of a toilet or bathroom and suits compact rooms. The boiler is intended to be installed vertically with a bottom water supply pipe connection.

The 80-liter tank of the model is covered inside with high-quality sapphire enamel, which withstands significant temperature and pressure fluctuations. The water in the boiler tank heats up to a maximum temperature of 75 °C. The heating process from 15 to 65 degrees Celsius takes just under 2 hours. This rapid heating and prolonged retention of heat are ensured by a "dry" element with a power of 1500 W.

Additional protection of the boiler's "insides" from corrosion is provided by a magnesium anode, which should be replaced regularly. The management of the Midea D 15F6(D) is mechanical — a simple rotary handle sets the desired water heating temperature. The model is suitable for a family of 3-4 people. There are no serious defects, and minor flaws are merely the characteristic gurgling sounds during water heating, which do not create much problem.

The Eldom Style Dry Slim storage water heater of Bulgarian origin belongs to the family of narrow boilers that allow saving space in rooms with limited area.

The model is made in the form of a round barrel with vertical installation measuring 38 cm in depth, 36 cm in width, and 111 cm in height. The heating of water in the boiler structure is carried out by two "dry" heating elements with a total power of 2000 W, housed in metal sleeves to prevent direct contact with water. As a result, no limescale accumulates on the heating elements due to hard water, thereby saving electricity and time on device maintenance — the replacement of heating elements is possible without tank depressurization.

All scale is absorbed by the soluble magnesium anode. With its regular replacement, the tank of the water heater will last a long time without the risk of leaks forming. The thickness of the steel walls of the tank is 1.8 mm, and its entire surface is covered with enamel containing increased zirconium content. Heating the entire volume of the apparatus from 20 to 60 °C takes 1 hour and 50 minutes.

Traditional mechanical handle at the bottom of the case is responsible for adjusting the water heating degree in the boiler. A temperature scale with a pointer heating indicator is displayed on the front panel of the water heater. As for complaints about the model, there are only audible knocking noises during the water heating process. Nonetheless, beyond the washroom, the sounds will not disturb the household, making the Eldom Style Dry Slim a reliable and affordable water heater with two "dry" heating elements highly recommended for purchase.

Thermex boilers with Italian roots are rightly popular in many European countries. Behind the traditional appearance of the Nika 80 V model in a cylindrical body hides a modern heating system using a "dry" heating element.

The dry heater in the Thermex Nika 80 V structure does not contact water, thus preventing limescale deposits on it. The boiler's heating element has a power of 1500 W and heats water up to a maximum temperature of 75 °C. The model is intended for vertical installation with a bottom water supply pipe connection.

The inner walls of the 80-liter water heater tank are coated with bio-glass porcelain. In properties, this material is as close as possible to real glass. As a result, the boiler is reliably protected from corrosion "from the factory." Additional protection for the tank is provided by a magnesium anode, which must be regularly replaced to extend the water heater's service life.

The Thermex Nika 80 V is equipped with a single control element — a rotary handle for setting the desired water heating temperature. On one panel with the handle are installed work indicators, and an embedded analog thermometer is displayed on the front of the cylindrical body of the device. The manufacturer provides a one-year warranty on the boiler's electrical equipment and a 5-year warranty on the tank's integrity.

Inside the Tesy Dry 80 V boiler, two "dry" heating elements are installed. In total, they output up to 1600 W of power and heat the entire usable volume from 20 to 65 °C in about 2 hours and 20 minutes.

The pair of heating elements is placed in enamel-coated tubes to prevent direct contact with water. The boiler tank has a useful volume of 71 liters and is made of high-quality cold-rolled sheet steel. To prevent the formation of corrosion foci, the internal walls of the tank are coated with a layer of heat-resistant glass-ceramic enamel. For enhanced protection against rust, the tank also includes a replaceable magnesium anode.

The water heater is released in a cylindrical body with vertical wall mounting. The cold water inlet and hot water outlet pipes must be located at the bottom. For incoming water, a special PISTON Effect nozzle design is used here, slowing down the mixing of cold water with already heated water masses.

To minimize heat loss, Tesy Dry 80 V uses high-density insulation INSUTECH. Additionally, the model is awarded a hygiene certificate for clean drinking water — the water heater’s materials do not alter the water's physical, chemical, and biological properties. The model lacks only a power cable. However, this makes it easier for the user to choose the appropriate solution for specific water heater installation conditions.

Hotpoint-Ariston BLU1 R PL Dry is a quality product from a trusted brand, aimed at household use by a family of 3-4 people for showering or for multiple users when drawn through a faucet.

Inside the boiler is a tandem of two 750 W "dry" heaters in protective enamel-coated tubes. Enamel is also used as a coating for the 80-liter capacity steel tank of the water heater. The TITANSHIELD coating withstands strong temperature fluctuations and pressure changes.

Cold water entering the boiler is held in the lower part of the tank using a special deflector. NANOMIX technology is directed at preventing mixing of cold and already heated water layers, which ensures high efficiency in hot water usage. The internal tank volume of Hotpoint-Ariston BLU1 R PL Dry is heated from 20 to 75 °C for 2 hours and 40 minutes.

A simple and reliable mechanical thermostat is responsible for regulating the water heating degree in the boiler's design. Meanwhile, a bimetallic thermometer handles the heating indication. Furthermore, the model has acquired a magnesium anode, which attracts all "contaminants" (scale, limescale, and various deposits). As a bonus, the water heater is equipped with a residual current device (RCD) to prevent electric shock.
