Boiler for water heating - which one to choose 50, 80, 100 and 200 liters. How it works + Video. Devices that have the ability to heat water for household and industrial needs are called boilers.
The need for them is due to the impossibility of connecting to the centralized network of this service; the absence of the network itself in the area of residence, the connection entails non-recoupable spending of finances, the connection process requires a long period of time by agreement, an individual home management system has been introduced: " Smart home".
A boiler for heating water in these situations is suitable for all parameters.
In terms of technical relation to the method of heating water. Boilers are divided into storage devices and flow devices.
They consist of a water heating system and a tank, in which liquid accumulates, and then heats up and goes to the consumer.
Tanks are made of different materials and have a coating that protects the base material from water and temperature:
Assembled from spirally bent copper tubes with nearby heating elements. The option of having a small capacity with an electric heating element built into it is possible. The volume of the tank is calculated on the amount of water that can be heated to the required temperature with a constant flow.
This characteristic differs mainly in storage devices.
Note! Gas flow columns have only external resemblance.
Industrial versions are installed in separate rooms called boiler rooms.
The operation of all types of boilers is based on one principle of operation, a heat source transfers energy to water as a heat carrier.
Differences are only in design:
The combustion chamber is located under the water tank. The principle of convection works here. The heated layers rise and the cold water sinks to the bottom.
The titanium chimney tube runs in the middle of the structure. Hot air, rising through the pipe, additionally heats the water. At the top of the tank, there is a cold water supply with a valve system for stopping filling when a critical level is reached, and a safety valve for emergency relief of steam pressure in case of boiling of the coolant is installed.
The smoke evacuation system by means of bends and bends is arranged in a way to extinguish sparks.
The heat exchanger in instantaneous water heaters are steel or copper pipes laid in a spiral over the tubular burners.
The system is controlled by mechanics and electronic controllers.
The machine is in constant working condition. If there is no liquid flow, water does not enter the system, the inlet valve prevents the supply gas valve from opening. The grates do not burn, and only the wick burns in case of a command to start work.
During hot water consumption, cold liquid begins to flow into the system, the thermostat gives a command to supply gas to the burners, the wick ignites the gas. The fire heats up the contents of the tubes. When the required temperature is reached, the thermostat turns off the gas supply or reduces its pressure to a minimum. At the end of the parsing of water and equalizing the pressure, the inlet valve also commands to stop the gas supply. This is a multi-level logical system in principle.
Additional sensors for air analysis and lack of draft in the chimney also work. They are responsible for security.
Storage gas boilers operate on the principle of heating water in solid fuel boilers, but with a safety system for gas operation.
They are supplied with electricity through a process control system.
It includes control elements for temperature, water pressure and liquid level.
The principle is similar to the operation of a flow-through gas boiler. But in electric boilers it is possible to maintain a constant required ambient temperature. This is a more economical option against the process of heating the entire volume of cold water to the required parameters.
The device is a thermos. The water tank is equipped with a heating element and thermostats, and is provided with constant cold water supply. The adjustment is carried out by a valve system.
Water is removed and its supply is organized in automatic mode. Below is the control system.
It ensures the operation of the device and ensures safety by means of sensors that signal when an electrical circuit is closed or a leak occurs. All boiler components are located inside a metal casing with a layer of thermal insulation. It does not allow the liquid in the boiler to cool for a long time.
Electric instantaneous water heaters are designed for low liquid consumption. They are mainly used for technical needs when washing food and dirty dishes.
Alternatively, you can use powerful shower channels. Their principle of operation lies in the passage of cold water through a heat exchanger in the form of tubes built into electric heating elements. The control system reacts to the pressure in the coil system and the increase in temperature.
Such a boiler consists of a tank with a large amount of water from 100 liters to 300 liters.One or more heat exchangers are located inside it. It depends on the number of heat sources connected to it. Convenient option for multiple sources. These can be:
The water in this accumulator is always at the same temperature. Mixing has little effect on the temperature level. Cold water is supplied from the cold water system through a simple float valve. Heating takes place constantly and all year round.
When choosing a boiler for heating water, it is necessary to take into account the number of people living, this is a criterion for the volume of water consumption. Frequency of use, how many people work. This is the reason for the simultaneous use of the apparatus.
Which is more economical to use, natural gas or electricity.
You can decide and make your own indirect heating boiler.
There is a lot of water, constantly warm water, enough for everyone.
