This problem is important not only for city apartments, but also for suburban cottages.
Water heaters save the situation. In houses and apartments without centralized hot water supply, equipment is installed that provides hot water. The industry produces large boilers with a water tank and flow samples. The first option is storage models, they are large in size, power, high cost. Relate to the pressureless type. The second option is inferior to the first in power, but has a number of advantages. How to choose a flow heater that meets your own needs?

Features of instantaneous water heaters
Flowing models are small, so they are suitable for urban apartments, cottages. This is a pressure type technique, as it is connected to a water supply system. The industry produces equipment with different throughputs, water heating capacity. In a large abundance of offers, it is difficult to navigate and make the right choice. How to purchase the necessary equipment without overpaying for unnecessary functions?
A family of 3 and a large family consume varying amounts of water. The higher the technical data of the heater, the more expensive it costs. There is no need to purchase powerful equipment if its capabilities are not used. And on the contrary, it makes no sense to acquire equipment whose capacity is not enough for the needs of people.
Compact equipment with few features suitable for kitchen, shower, cottages. The average technical parameters are most in demand, since models with such capabilities are able to provide a family of 4 with hot water. Large and powerful heaters are installed in apartment buildings, small hotels, and sports facilities.
An important indicator is the method of heating - gas and electrical appliances imply the presence of this particular energy source in the house.
The use of instantaneous water heaters makes the consumption of hot water comfortable. This type of equipment has several advantages:
- small sizes;
- high speed of heating water;
- wall mount, which allows you to economically use the area of the room;
- manufacturers produce gas or electricity models;
- modern design technology.
Flowing water heaters do not have a tank. The heating process is carried out by the heating element during the flow of water through pipes inside the equipment. Due to this technical solution, it was possible to achieve compact dimensions of the equipment, significantly increase the speed of water heating.
Flowing heaters differ in several ways:
- heating method - gas and electric;
- power of the heating device;
- water flow rate.
Electric water heaters are independent of gas availability. To work, they need a large current. Such equipment is connected to one or more points - in the kitchen and bathroom. Despite the fact that they consume a lot of energy, they work without fail, providing domestic needs for hot water.
Connection to the power grid allows the use of low-power equipment in cottages where there is no natural gas supply or is just planned, as a small insurance in case of interruptions in the centralized supply of hot water.
For the operation of more powerful water heaters, reinforced wiring is required, so they are installed in houses with electric stoves.
Gas appliances are more expensive, but also more powerful. They are popular in apartment buildings where there is no centralized hot water supply. For modern gas heaters, the pressure head of the water does not matter - they work under any conditions. For normal operation, the presence of gas is necessary, therefore, such equipment is bought in houses with gas stoves.
How to choose a instantaneous water heater
Choosing a model, one should proceed from the size of the room in which the installation of equipment is planned, the need for hot water, and financial opportunities. Compact samples placed on the wall are convenient in small apartments, and equipment of large sizes requires additional space.
Kitchen heaters
Families rarely install heaters designed exclusively for kitchen needs. This room is equipped with solid devices serving kitchen and hygiene needs. High power and fast heating of large quantities of water provide gas heaters. They work not only for kitchen needs, but also connect to the communications of the bathroom.
If necessary, you can install a small electric appliance that provides hot water for washing dishes. This technique is mounted on the wall. It is compact, easy to install, does not require special wiring.
Water heaters for a summer residence
Electric devices of low power will quite cope with the load in the country house. Quickly heat water to take a shower after working on the site or wash dishes after a picnic with a device with a power of up to 3 - 3.5 kW. The kit may include nozzles for connecting to a faucet, to a shower or a faucet + shower model.
These are small, inexpensive, stylish devices. They fit well into the modern interior, have a security system that ensures reliable and long-term operation of the equipment. To connect a small electric water heater, just connect it to the water supply. Samples have a wall mount.
Shower water heaters
Compact and economical units with low power and a shower head are installed in shower cabins. They quickly solve the problem of supplying hot water in small volumes. The maximum speed of water passage is 6l / min. Low-power (up to 3.5 kW) and easy to install, these heaters have proven themselves in small apartments, bathrooms with limited space. Mounted on the wall. They have a white, rarely silver color.
Gas heaters are powerful, large, so placing them requires a lot of space. Popularly, this technique is known as gas water heaters. The installation of such equipment requires the presence of a chimney, traction control. Some modern models provide for the transition from natural gas to liquefied natural gas. Safety standards are increased in comparison with old models of geysers.
Stylish design is well received in a modern interior. Well thought-out lines and shapes allow the equipment to fit into any design. They have a long service life, reliable, practical.
