The best 80 liter boilers with “dry” heating elements

The NOVAtec brand produces water heaters that are quite popular on the domestic market. One of these is the Direct Dry model with two “dry” heating elements.

“Dry” heating elements in the boiler design are placed inside enameled tubes and do not come into contact with water. Their total power is 1600 W - the device heats a full tank of water in about 2.5 hours. The water heater is placed in a vertical orientation, the water supply system pipes are connected to it from below.

The inner walls of the NOVAtec Direct Dry tank are covered with titanium enamel - the coating reliably protects the product from corrosion and the negative effects of hard tap water. Also, to prevent rust formation, the model is equipped with a dissolvable magnesium anode. “How a magnesium anode helps a boiler last longer and how it needs to be maintained” - we talked about in the material of the same name.

Subject to compliance with the terms of annual scheduled maintenance, the tank of the model is provided with a 7-year warranty from the manufacturer. However, many water heaters fail earlier due to tank leaks. Another problem in the model’s garden is unreliable information on the temperature scale, which is a problem with some boiler samples. Whether you put up with these nuances or not is up to you to decide. In the vast majority of cases, NOVAtec Direct Dry does not cause operational problems.

Model GBH B DD from the Ukrainian brand of household appliances Grunhelm is a simple and unpretentious “workhorse”, designed for preparing hot water and distributing it to several water points.

The boiler has the usual cylindrical body shape with overall dimensions of 77.2x46.2x46.5 cm. The water heater is installed exclusively in a vertical plane, pipes are supplied to it from below. The tank of the model has a capacity of 80 liters of water. To protect the tank from corrosion, titanium enamel is applied to the steel walls using a liquid method and fired at a temperature of 850 ° C.

An auxiliary element in protecting the tank from rust is a dissolving magnesium anode, which must be replaced with a new one from time to time. The “dry” heating element with a power of 1600 W does not come into contact with water, which prevents scale deposits on it. Such heating elements can be easily replaced when they fail without the need to depressurize the tank. Due to the use of one heater, the water in the boiler heats up slowly, but the heat is retained for a long time thanks to the effective thermal insulation of the tank with a 20 mm layer of polyurethane foam.

The model uses the Antimix technology, which prevents layers of cold and already heated water from mixing. It eliminates temperature changes when using water from the boiler. Grunhelm GBH B DD is suitable for domestic use and can satisfy the needs of a family of 3-4 people.

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.

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.
