The best 80 liter boilers with “dry” heating elements

The Chinese company Midea is known as a well-known manufacturer of air conditioners and other household appliances. One of the brand’s profit items is formed by storage water heaters. In particular, the 80-liter boiler D 15F6(D) is in demand among the public.

The water heater is assembled in a narrow, tall casing: its diameter is 38.5 cm and its height is 103 cm. The device takes up little space in the corner of the toilet or bathroom and is suitable for small rooms. The boiler is supposed to be placed vertically with the lower pipes of the water supply system.

The model’s 80-liter tank is coated on the inside with high-quality sapphire enamel, which can withstand large changes in temperature and pressure. The water in the boiler tank is heated to a maximum temperature of 75 °C. The water heater spends a little less than 2 hours of pure time on the heating procedure from 15 to 65 degrees Celsius. Such fast heating and long-term heat retention is ensured by a “dry” heating element with a power of 1500 W.

Additional protection of the “insides” of the boiler from corrosion is provided by a magnesium anode, which must be replaced regularly. The Midea D 15F6(D) has a mechanical control - a simple rotary knob sets the desired water heating temperature. The model is suitable for a family of 3-4 people. It has no serious shortcomings, and the only minor flaws noted are the characteristic gurgling sounds when heating the water, which do not make any special difference.

The storage water heater of the Bulgarian breed Eldom Style Dry Slim belongs to the group of narrow boilers that allow you to save free space in rooms of limited area.

The model is made in the form factor of a round barrel for vertical installation with dimensions of 38 cm in depth, 36 cm in width and 111 cm in height. The water in the boiler design is heated by two “dry” heating elements with a total power of 2000 W, which are placed in metal casings to avoid direct contact with water. As a result, lime does not accumulate on the heating elements due to hard water, which saves electricity and time on device maintenance - replacing heating elements is possible without depressurizing the tank.

All scale is removed by the dissolving magnesium anode. If you replace it regularly, your water heater tank will last a long time without the risk of leaks. The thickness of the steel walls of the tank is 1.8 mm, their entire surface is covered with an enamel coating with a high zirconium content. Warming up the entire volume of the apparatus from 20 to 60 °C takes 1 hour 50 minutes.

A traditional mechanical knob at the bottom of the body is responsible for adjusting the degree of water heating in the boiler. There is a temperature scale with a heating dial indicator on the front panel of the water heater. Some complaints about the model include only audible knocks during the water heating procedure. However, sounds outside the bathroom will not disturb household members, so Eldom Style Dry Slim can be safely recommended for purchase as a reliable and inexpensive water heater with two “dry” heating elements.

Boilers with Italian pedigree Thermex enjoy deserved popularity in many European countries. Behind the traditional appearance of the Nika 80 V model in a cylindrical body lies modern heating using a “dry” heating element.

The dry heater in the Thermex Nika 80 V design does not come into contact with water, which prevents scale deposits on it. The heating element of the boiler has a power of 1500 W, and it heats the water to a maximum temperature of 75 °C. The model is subject to vertical installation with lower water supply pipes.

The internal walls of the 80-liter water heater tank are covered with bioglass porcelain. The properties of this material are as close as possible to real glass. As a result, the boiler literally “from the factory” is reliably protected from corrosion. Additional protection for the tank is provided by a magnesium anode, which must be changed regularly to extend the life of the water heater.

Thermex Nika 80 V is equipped with a single control element - a rotary knob for setting the desired water heating temperature. On the same panel with the handle there are lamp indicators of operation, and on the front side of the cylindrical body of the device there is a built-in analog thermometer. The manufacturer provides a one-year warranty on the electrical equipment of the boiler and a 5-year warranty on the integrity of the tank.

Inside the Tesy Dry 80 V boiler there are two “dry” heaters installed at once. In total, they produce up to 1600 W of power and heat the entire useful volume from 20 to 65 °C in approximately 2 hours 20 minutes.

A couple of heating elements are placed in enamel flasks to prevent direct contact with water. The boiler tank has a usable volume of 71 liters and is made of high-quality cold-rolled sheet steel. To avoid the formation of corrosion spots, the internal walls of the tank are coated with a layer of heat-resistant glass-ceramic enamel. To enhance the anti-rust effect, the tank is equipped with a replaceable magnesium anode.

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

In order to minimize heat loss, Tesy Dry 80 V uses INSUTECH high-density polyurethane insulation. The model has also been awarded a hygienic certificate for clean drinking water - the materials used to make the boiler do not change the physical, chemical and biological properties of water. The only thing missing from the model is the included power cable. However, the easier it is for the user to choose a suitable solution for the specific conditions of installation of the water heater.

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

A tandem of two 750 W “dry” heaters in protective flasks with an enamel coating is installed in the “inside” of the boiler. Enamel is also used as a coating material for a steel water heater tank with a capacity of 80 liters. TITANSHIELD coating withstands strong temperature changes and pressure fluctuations.

When cold water enters the boiler, it is retained in the lower part of the tank by means of a special divider. NANOMIX technology is aimed at preventing mixing of layers of cold and already heated water, thereby achieving high efficiency in the use of hot water carrier. The volume of the internal tank of the Hotpoint-Ariston BLU1 R PL Dry heats up from 20 to 75 °C in 2 hours 40 minutes.

A simple and reliable mechanical thermostat is responsible for regulating the degree of water heating in the boiler design. In turn, heating is indicated by a bimetallic thermometer. The model also acquired a magnesium anode, which attracts all the “evil spirits”(limescale, scale and all kinds of deposits). As a bonus, the water heater was equipped with a residual current device (RCD) to prevent electric shock.
