Rating of the best boilers per 100 liters in 2022

100-liter water heaters are considered the best option for providing hot water needs for a family of 3-4 people. This device is not only acceptable for a private house or apartment, but also suitable for a small gym. Through the model with the specified volume, you can take a shower several times in a row, while not wasting much time warming up the liquid.

Specifics of storage systems for heating water

They operate on the principle of liquid heating by means of electrical devices, as well as by burning natural / liquefied gas and transferring the resulting heat to a liquid medium. Their 100-liter water storage tank has special features that ensure safe and reliable operation for a long time, with a special feature being the ability to maintain heated water for a relatively long time.

The main technical parameters of such tanks include the presence in their design of a special magnesium anode that prevents the formation of rust, as well as the application of a special anti-corrosion layer to the inner surface, which prevents the harmful effects of the heated liquid on the tank. Also, the structure of the system includes a thermostat, various protective thermal sensors, safety and check valves. 100-liter containers are subjected to reliable technological insulation so that the water inside cools down as long as possible.

IMPORTANT! Any boiler is equipped with two branch pipes brought out to the outside: for connection with the plumbing system and receiving cold water - a blue pipe, for hot water - red.

Advantages and disadvantages of models per 100 liters

Of the advantages of the considered models of boilers, the following can be distinguished:

• A wide choice of models in terms of their design features (different areas of application, different places and installation positions, etc.);
• Relatively low heat losses during storage of heated liquid in the tank;
• Low power consumption - from 5 to 27 kW (when compared with flow analogues);
• Advanced defense system with multiple degrees;
• Possibility of integration into the “smart home” automated control system, where it is possible to assign heating at night automatically, under the action of preferential tariffs for paying for electricity at night (clear savings on energy carriers);
• Possibility of work from the accumulator;
• The presence of highly efficient heating elements;
• Multi-level system of anti-corrosion protection (the use of a magnesium anode, in particular).

Of the obvious shortcomings, it is possible to note:

• Somewhat inflated cost of the entire system (especially true for samples of Western production);
• If the mode of long-term maintenance of positive water temperature is turned on, then the power consumption will increase many times over;
• Internal heating elements require periodic descaling (especially if the water is hard).

Design and principle of operation

In most cases, the considered devices for 100 liters are made in a closed version and operate under general pressure. For the best performance of tasks, they are necessarily provided with a special protective group, relief valves, a communication device with an external water supply.

The design of the boiler includes:

• Protective casing - a housing equipped with a control panel and operation indicators;
• Inner layer of thermal insulation;
• Storage tank for 100 liters - storage of a heated liquid medium;
• Branch pipes - one with a divider for receiving cold water and the second for hot water;
• Heating element - heating element or gas burner;
• General protection system - prevents pressure increase, temperature increase (includes thermostatic sensors and reset devices);
• Special protection - made on a magnesium anode.

Modern types of storage boilers

They can differ in the heating system and the position of placement in space. The choice of one or another type will depend on the owner's capabilities both in terms of the energy carriers used and in terms of providing the device with a working space.

Electric heating

These 100 liter models are the most popular and are widely used in areas where there are certain difficulties with central water supply. Unlike their gas counterparts, they have a slightly different general protective system, use electrical heating components and do not have automatic smoke extraction. The liquid is heated in them by one or two heating elements, with an average load of not more than 2 kW. If the device contains more than one heating element, then an energy-saving system can be included in it, operating in three modes:

1. "Economy" - 0.8 kW;
2. "Optimum" - 1.2 kW;
3. "Maximum" - 2.0 kW.

Thermostatic protection and heater setting can be done in electronic or analog form. Analog (i.e. mechanical) have a bimetallic plate that opens the electrical circuit when the liquid is heated to a predetermined temperature.

gas heating

Such 100-liter boilers are considered the most economical devices for heating liquids. Models are equipped with a reservoir-accumulator, which is distinguished by its robust design and is maximally protected from corrosive influences. The device can maintain moisture in a heated state for a long time, while minimizing gas consumption. The gas safety system has three levels and is based on the operation of a safety valve, which simultaneously maintains the overall protection of the equipment and prolongs its operational life.

The basic features of gas water heaters include:

• Maximum adaptation to the technical conditions of low-mode operation in water / gas networks;
• They are equipped with fireboxes with an open / closed system for the elimination of combustion products (open ones involve working with natural draft, and closed ones work through forced air circulation);
• Maximum saving mode of gas consumable mixtures;
• The outer case is made of stainless steel;
• Enamel anti-corrosion coating is highly resistant;
• There is an automatic ignition of the burner from a piezoelectric element plus control of thermal steam from a flame;
• The presence of a magnesium anode;
• Ecological cleanliness, proper thermal insulation (preservation of heat loss within the limits of up to 20%).

Gas models will be an excellent choice not only for home use, but can also be used to solve small industrial problems.

indirect heating

In such devices, the heating of the liquid is carried out through several energy carriers - directly electrical energy and heat from the hot carrier obtained from the central water supply. Models can be located in space both in vertical and horizontal positions, be floor or wall.Heating with the help of electrical energy in such devices is carried out in the event of a DHW shutdown or a general shutdown of the heating system (typical for the summer period). The warm-up procedure is carried out using a ceramic-based heating element, which is controlled by an appropriate thermostat. Protection against rising pressure is provided through a safety valve. Temperature heating limits are from +10 to +75 degrees Celsius. The parameters of the used current are 50 Hz at 230 W, the class of electrical insulation protection is IP 45 (it is allowed to place the equipment in rooms with high humidity). The performance of an indirect type water heater for a volume of 100 liters will directly depend on the power of the energy source (power from the central power grid is preferable to power from a fuel generator).

Floor and wall structures

The structural placement of the boiler in space depends on its own weight. Speaking specifically about 100-liter models, they are most often produced in a suspended version. However, to place such equipment on the wall, it (the wall) must have special strength characteristics (i.e., it must be made of reliable material). Suspended variations are considered more convenient, because they provide better supply / output of liquid and are able to provide proper heat transfer, while not mixing layers of hot and cold moisture (for outdoor devices, such a task is simply impossible). Describing floor water heaters, one can note their only undoubted plus - they all have special cross-shaped metal fasteners that prevent the destruction of the body under the onslaught of a large volume of liquid medium.Also, their outer parts are equipped with special heat-resistant materials that perfectly retain heat.

Flat models as a separate type of 100-liter water heaters

Their development was carried out specifically in order to create some kind of alternative for storage devices with large sizes in terms of combating the shortage of space. At the same time, the vector of using innovative materials in the production technology was set, so flat boilers are made exclusively from special plastic or stainless steel. They are produced with an electronic control panel, which simplifies the adjustment of the tuning and heating processes. The units have an automatic internal diagnostic system and can independently monitor and detect malfunctions during operation, immediately offering possible troubleshooting options. However, flat models, as practice shows, have a short service life.

Flat models with stainless tank

Their main positive quality is to give the structure a special level of strength due to the tank made of stainless steel, which, of course, also affects the increase in service life. Users notice that such models are little whimsical in maintenance and have some advantages over other flat "brothers", in particular:

• Increased anti-corrosion resistance of the tank;
• Almost absolute chemical neutrality;
• After heating, the liquid medium does not receive foreign tastes and odors;
• Good thermal stability;
• Decent operating period;
• Aesthetic appearance.

Flat vertical models

These samples are also well-deservedly popular because they can be compactly integrated into a limited space.The vertical arrangement of the equipment, by the way, implies an accelerated heating process, and this, in turn, means a reduction in energy costs. For such devices, the heating element is installed in the bottom part and cold liquid is supplied directly to it. It is possible to connect several water points to a vertical sample and use them simultaneously. The main advantage can be called a small operating threshold - the system can start working at a pressure of only 0.5 bar, while consuming a minimum of electricity. In general, the unit does not need a high-ampere power supply line, it does not require a special installation permit. At the same time, we can note an understandable level of adjustment, increased reliability of operation, and a small need for preventive maintenance. Of the minuses - a long heating period.

Flat horizontal models

Most often they are used where there are difficulties in ensuring the freedom of high-rise space. The inner tank is made of stabilized steel, and the outer surface is coated with bioglass factor. The design is environmentally insulated against loss, the outer casing is protected by powder-based enamel. The working component of the device is a heating element with a power of 0.7 to 2 kW, anti-corrosion protection is implemented through the use of a magnesium anode.

Difficulties of choice and requirements for safe operation

When buying a boiler for 100 liters, you should pay attention to the following points:

• The volume of the tank is 100 liters - it can be enough for a family of 5 people;
• The power of the heating element is usually two heating elements with a total power of up to 2 kW, and the heating period can be up to 120 minutes;
• Internal protective coating - the economy class provides enamel or glass ceramics, more expensive devices are coated with a titanium-based coating or are immediately made of stainless steel;
• Warranty period - for stainless steel equipment, it should be at least 7 years, the rest may be less;
• The type of heating element is insulated (“dry”) and non-insulated (“wet”), the first is considered safer, because it does not have direct contact with water;
• The quality of thermal insulation - this parameter is responsible for the length of the time period during which the heated liquid retains its temperature (naturally, gradually losing degrees). Foamed polyurethane is considered the best material here.

Basics of operating basic boiler models:

• The cold water tap for the intake must be open until all the air comes out of the pipe and the stream becomes uniform;
• Always close the mixer valve, while leaving the liquid supply line open;
• The supply of electricity for heating is turned on only after filling the tank and checking for various leaks;
• After that, you should set the desired power and the required heating temperature;
• It is advisable to periodically monitor the work process (maximum time - 2 hours).
