Advantages and disadvantages of steam heating in a private home
steam heating is not very popular with the owners of private houses. I use it in rare cases. But such systems have their own advantages and disadvantages.
steam heating Goodies:
- High efficiency heating. A small number of batteries are required to heat the house. In some cases enough pipes are enough.
- Slight inertness of the system. Because of this, the heating rate of the system is quite high. A few minutes are enough for the sensibility of heat.
- Minimum heat loss. So the system becomes the most economical.
- You can take breaks during operation. Due to the small amount of water in the pipes, the system does not defrost.
But the most important advantage - system efficiency. To build such heating, you do not need to buy expensive equipment. And the process of using it does not require special expenses. But at the same time, there are significant shortcomings. The most significant negative is the danger of the heat carrier, which is a high-temperature steam.
During operation, all elements of the system are heated to 100 degrees, and even higher. Any contact with heated parts will cause a burn. That's why the entire system must be of a closed type. This is especially important for families with children. Due to the high temperature of the radiators, the air begins to circulate actively in the room. This creates discomfort, and sometimes allergic reactions to dust.
When using steam heating, it is necessary to prepare for the dryness of the air. You will need to purchase additional moisturizers. There are also certain limitations when choosing finishes for pipes and radiators.
It is recommended to use cement plaster, which is painted with heat-resistant paint. The rest of the materials are rather doubtful. Also, when operating the steam heating system, there is noticeable noise, which certainly affects the comfort of living. In addition, the system can not be controlled, which often leads to overheating of the house.
Pipes for steam heating are selected only from metal. The remaining options can be dangerous when used.
Automation can be installed to monitor the system. It will control the temperature and, if the room is cooled down, it will start heating. But such fluctuations are quite uncomfortable. Also, it is possible to equip several parallel heating branches, which will be started as needed.
But the main disadvantage of steam systems is their failure rate. When a pipe or radiator breaks through the room, hot steam will burst into the room. For this purpose, such heating is prohibited in production and apartment buildings. In a private house, such equipment is installed under the personal responsibility of the owner.
steam heating circuit
main element of the system is a steam boiler. Its task is to convert water into steam. The equipment consists of a collector, a drum and a pipeline. It also provides for a water space - a container with a coolant. When working around a container a vapor space is formed.
Inside the vapor space, air separation structures are mounted. All boilers are divided into 2 types: fire-tube and water-tube. In the first variant, gas flows through the pipes, and in the second, water.
Principle of water transformation into steam:
- Prepared water is sent to the tank, which is located in the upper part of the boiler;
- The liquid is sent to the collector;
- Further flows into the upper drum, bypassing the heating zone;
- Inside the pipe, steam is produced, which rises;
- The separator separates the condensate and the steam is sent further.
Next it is worth considering the design of pipes and radiators. High temperatures of steam exclude the use of plastic and metal-plastic elements. It is best to use steel pipes. They are strong enough and able to withstand high temperatures. But the material is corroded and will not last long. In addition, when installing such equipment will have to use welding, which is quite difficult.
The ideal material for pipes with steam heating is copper. It is resistant to high temperatures and corrosion option, but expensive.
Radiators for the heating system must be strong. It is better to choose cast iron options. Sometimes you can use finned steel pipes.
Varieties of steam generators for heating the house
There are many options for performing steam heating. The varieties are distinguished by the number of pipes: single-tube and two-pipe versions. The first option involves the continuous movement of steam.
Sometimes the steam does not condense and can get into the branch for tap. To prevent this, a drain trap must be installed after each battery.
Minus one-pipe system - the difference in heating radiators. Batteries that are located near the boiler, heats up better. But it will be noticeable only with large houses.
The two-pipe system assumes one condensate pipe and the second one for drainage. So the temperature in all batteries remains the same. But the flow rate of pipes increases. In this case, the steam boiler can heat not only the radiators, but also the boiler.
- Upper. The steam pipe is located above the heating devices. From it drop pipes to batteries. The conduit is mounted on the floor.
- Lower. The pipes are placed below the heating devices.
- Mixed variant. The pipeline is installed slightly above the batteries. The rest repeats the top wiring.
Also distinguish systems beyond the level of internal pressure. Isolate the vacuum version and atmospheric. In the first form, airless space is achieved through a special pump. Atmospheric systems have a high pressure, which can lead to significant hazards during accidents.
Principle of operation of steam boilers for a private house
Steam heating is heating by means of a steam, which is formed as a result of boiling water in the boiler. Further the steam comes through the pipes into the batteries, which can be placed throughout the house. Such a system is known for more than a hundred years.
Steam generator circuit:
- Boiler - used for heating and boiling water;
- Exhaust Valve;
There are open and closed heating systems. A pump is used to circulate the condensate. In the closed version, the steam itself enters the boiler under the influence of physics and a small slope of the pipes.
Also systems are divided into high pressure, low and vacuum-vapor versions. Each system has its own technological nuances and characteristics. Heating is affected by the length of the pipeline from the boiler to the furthest radiator.
There are 2 pipe distributions: one-pipe and two-pipe. In the first variant, only one pipe is used for the movement of steam. In the second, steam moves one pipe, and the other returns condensate.
For private houses, a two-pipe system is most often used. In this variant, it is possible to adjust the temperature with a special valve. In a single-tube design, temperature control is only possible if the unit's power is reduced. And this is a risky underheating in the cold seasons of the year.
How to make steam heating from the
Furnace heating system consists of two stages. In the first it is necessary to draw up a draft and a scheme. In the second stage, they begin to install steam heating with their own hands from the furnace or boiler.
The system design is first executed. The boiler output is determined. It is important to consider the type of fuel and the possibility of heating the liquid for domestic needs.
. All data on the placement of pipes and radiators are applied to the paper. According to the plan, the system is installed.
In the diagram it is important to consider the location of the boiler, the area of the room and the conditions for installing the system. Also take into account the number of pipes. At the same time, all financial calculations are made.
- Create wiring diagram.
- Installation of radiators. The best placement is near the window.
- Fastening the expansion tank. The capacity is connected to the pipeline.
- Piping installation. The pipe is led to the battery, cut off, and all inputs and outputs are connected. Also, the pipes are piped to all radiators.
- Circuit closures - connection to the heat generator.
- Boiler installation.
The boiler can be installed in any convenient location. But the longer the pipeline, the more expensive the system will be. The installation of the boiler in this case is no different.

Steam heating on wood is less popular than other heating options. You can equip this option with your own hands. At the same time, you can make heating by steam even from the stove. But it is important to be prepared for the difficulties that this system can bring.
