A boiler is a heater that allows you to provide hot water to the whole family, and if it works using indirect heating technology, then family members can even use hot water at the same time. A feature of this device is that it does not have a heating source, and the heating itself is carried out using indirect heaters, characterized by an external location. For example, a heating boiler or even a central heating system can be used as a heat carrier in such a boiler.

An indirect heating boiler solves the problem of lack of hot water while it is used by family members. With such a device, you can wash dishes in the kitchen and take a shower in the bathroom at the same time without any discomfort, since the boiler has its own hot water tank. An example of reliable water heaters is Drazice indirect heating boilers.

Various types of water heaters are presented on the company’s website Dom-climata.ru.

Design features

It is a fairly large cylindrical container. Its main structural elements are:

• frame;
• steel tank;
• warming;
• heat exchanger (steel or brass tube located near the bottom of the boiler);
• thermometer;
• an anode made of magnesium and protecting the tank from corrosion.

Due to the presence of a heater in the design of the boiler, the daily heat loss does not exceed 4 degrees. With a thermometer, you can know what the temperature of the water is now in the tank.
The magnesium anode attracts to itself all the electrochemical processes that occur inside the tank. But over time, the anode will need to be replaced, as it is a consumable.

Features of choice

In addition to conventional boilers, there are also combined devices on the market that can be connected to alternative heating sources. For example, in the warm season, when the heating system is turned off, the boiler can heat water from solar energy or electricity.

Boilers of indirect heating differ among themselves primarily in the volume of the tank. There are tanks, the volume of which is from 5 to 400 liters. The choice of a boiler should be made based on the number of people living in the house, as well as on how much hot water is consumed per day.

For example, in order to simply wash dishes in the kitchen or wash your hands, a tank volume of 5 to 15 liters will suffice. But if a boiler is needed for a bathroom, then it is necessary to choose a tank with a volume of up to 100 liters. For the private sector, a boiler with a 150 liter tank may be required.

Thus, for a family of 1-2 people, a boiler of 50-80 liters will be enough. If 3 people live in the house, then the boiler must be at least 80-100 liters. For a family of 4-5 people — 100-150 liters. If more people live in the house, then a tank of 150-300 liters will be needed.

Gas water heater

For modern water heaters, it will not be a problem to provide us with hot water. Whether it is a cottage, office or home, a gas instantaneous water heater will work reliably and safely. Modern materials and technologies have made it possible to create it compact and simple, having nuances that you need to know about before choosing a household appliance.

A flowing gas water heater is known to us by another name: a geyser. The word «flow» in its name speaks of the principle of operation of the device, which consists in heating cold water at the moment it flows through the device. The heat of the fire heats the heat exchanger, which gives it to the water. Using gas as a fuel source creates an easy-to-maintain and powerful hot water production facility. The low price of gas guarantees us the opportunity to get hot water at the lowest cost. The use of advances in electronics allows you to fully automate the entire process of water treatment. The user has the most important privilege: turn on the device.

More recently, one could see how someone, burning their fingers, ignites a gas water heater. In modern instantaneous gas water heaters, gas ignites electricity.

It differs depending on the ignition method. piezoelectric and electric. In the first case, the start-up of the water heater is carried out by igniting the pilot burner using a piezoelectric spark. In gas instantaneous water heaters using the electric method of gas ignition, there is no need for a burner.
Electrically ignited water heaters save on gas, which is preferable if bottled LPG is used. As a source of energy for ignition, automation, as a rule, uses chemical energy sources (batteries).

The power of a gas instantaneous water heater is one of the most important characteristics of the device, measured in kW. For domestic purposes, water-heating equipment with a capacity of 17 to 30 kW is used. When choosing a gas instantaneous water heater, you should pay attention to the consumed and useful power of the device indicated in the technical data sheet. They will show the efficiency of the device and allow you to evaluate its performance. A flowing gas water heater with a useful power of 17 kW is capable of heating flowing water by 50 degrees Celsius at a rate of 4 liters per minute.
