A brief overview of popular types of water heating equipment

When choosing this category of household appliances, the functional characteristics of structures, as well as the ergonomics of models, are taken into account. According to the principle of action, water heaters are divided into 2 types:

electric;
gas.

Depending on the method of heating water, devices are distinguished:

cumulative;
flowing.

The general classification of water heaters is based on the following categories of equipment:

electric storage water heaters - the boiler is a thermos with heating. The unit is convenient in that it allows you to constantly have the right amount of hot water on hand;
electric instantaneous water heaters - water is heated in a stream. The device is able to meet the maximum needs for hot water, providing access to an unlimited amount of resource immediately after opening the tap;
gas storage water heaters - according to the principle of operation, they are similar to electronic analogues of equipment. At the same time, they have greater power compared to the latter, operate on liquefied or main gas;
gas instantaneous water heaters - the device is able to maintain the temperature of the feed stream, since the flame intensity of the gas column is automatically controlled by a modeling burner depending on the flow of water;
indirect heating boilers - the resources of the central heating system are used as an energy carrier.

When arranging a modern home, they often choose combined-type water heaters with several fuel options, which ensures uninterrupted operation of the equipment.

Electric storage water heaters

The principle of operation of boilers is simple: a thermocouple inside the housing heats the water in the tank to a predetermined temperature. Next, the thermostat fuse is triggered and the unit turns off. Depending on the volume of the tank, it takes time from 35 minutes to 6 hours to heat water under normal conditions. For rapid heating, the turbo mode is provided. The current catalog of boilers includes a model range of equipment for apartments, country houses and enterprises. Boilers vary in various ways. Volume of the tank:

compact options of 5-15 liters;
20-50 liters for a small family;
up to 200 liters for a large number of consumers.

Inner tank materials:

stainless steel, titanium coated, enamel;
glass ceramics, plastic.

According to the principle of management:

electronically controlled display;
manual regulators of water temperature and heating intensity.

By design:

horizontal
vertical.

According to the shape of the case:

in the form of a cylinder;
rectangular;
rounded
flat.

By installation method:

wall constructions - a convenient format for oversized models;
floor constructions - represented by samples with a tank volume of 100 liters or more.

If you plan to install a water heater in the kitchen, then you can choose a design with a mounting option above the sink or in the lower space below it.

Electric type instantaneous water heaters

The device is distinguished by the rapid preparation of a hot resource: the water stream is heated intensively, passing through a thermocouple. Automation turns off the heating when the water supply from the tap stops. In comparison with the analogues of the accumulative type, flow-through models of units are distinguished by high power and compact dimensions.

A brief overview of the characteristics of instantaneous water heaters

Flasks:

metal options transfer heat better than plastic;
the most durable stainless steel flasks;
copper flasks are most effective, in which water is heated with greater intensity than in samples from other materials.

Water heating:

equipment performance and heating intensity vary depending on the temperature of the cold inlet water;
Several heating modes and 2-step protection are provided.

Electronic control:

the design is equipped with a two-color display, which reflects the mode of the set heating temperature;
with the help of the regulator you can select the necessary parameters, then the automation provides the water supply of the desired temperature.

Varieties of instantaneous water heaters consume a lot of energy, and therefore the cost of paying bills increases.

Gas storage water heaters

The equipment works on a single principle with an electronic counterpart, it differs only in the type of fuel: the water is heated in a thermal tank using a gas burner. Unit Specifications:

by type of combustion chamber - closed and open. In the first case, there is no need to supplement the design with an air outlet, which determines the availability of installation in comparison with the second;
according to the installation method - wall and floor varieties;
ignition - piezoelectric or electric. The second option is safer and more convenient: the flame automatically turns on and off when the crane position is changed.

Modern models are equipped with sensors that shut off the gas supply in case of irregularities in the system.

Gas instantaneous water heaters

Geysers have the same characteristics as electric counterparts of the flow type - cold water is heated in the stream and fed to the tap in a given temperature mode. At the same time, the equipment is offered in a high price category, but in comparison with an electric counterpart, a gas water heater consumes energy economically, therefore, the high cost of goods is leveled. Geysers are equipped with a security system that can quickly heat the water flow to the set temperature and ensure maximum demand for hot water. Manufacturers also offer combined models of water heaters with a set of devices for connecting to various power sources, which increases the comfort of operation of the device.
