Heating - important question, which meets every owner of a house or cottage. Apart from the choice of equipment is necessary to define a heating fluid. Increasingly, people are thinking about how to use oil rather than water for the house heating system. There are many opinions on this issue, in which we try to understand.
Heating - this is important
The question arises of heating even during the design of a new home. Sometimes it appears if you change the mode of operation. For example, a person could buy a country house in which the last owners are only in the warm season. Now he is going to visit him in late autumn and winter. What to do? Not remain the same in a cold room? The answer is obvious - heating. It is important to choose what kind and how coolant. It depends on many factors.
Most tries to use its water system, as it is the least expensive and energy-intensive coolant. In this case, if the temperature drops below zero, then it freezes. As a result, the system will have to be warmed, and at best to brew some of the burst pipe. At worst - to change the whole system, including the boiler. This situation is not only pleasant, but also costly.
Therefore, water is used in winter for special additives to prevent freezing. They are different, ranging from the liquid with mineral salt, and ending with alcohol. Each has its own positive and negative qualities. Yet, none of them can not be called perfect. It is in this regard, many do not think that added to the water, and that it be replaced.
Oil as a coolant
As many known, oil has a significantly lower threshold freezing than the same water. Therefore, there are ideas to use it in the heating system. As in everything there are advantages and disadvantages.
dignity
Waste oil in the heating system has many advantages:
- In winter, the fluid does not freeze. Is that the house temperature drops to the level of -35 degrees Celsius. Agree, this is unlikely to be.
- No matter how long does negative temperature - it does not affect the oil. Enable and start the boiler to heat the room at any time.
- Low volatility due structure.
- No need to additionally pour any additives to coolant does not freeze.
- The oil has a high anticorrosive properties. Therefore there is no need to frequently flush the system.
- It has a high thermal stability.
disadvantages
Despite the obvious advantages of this type of coolant, there is still a number of shortcomings:
- The need for filtration prior to infusion into the system. The fact that working out usually is a mixture of a plurality of oils of different grades and viscosity. In addition, it contains a third-party components in the form of dirt and metal. The purification process can cost a considerable amount in a large amount.
- The presence of the desired amount. At the moment there are no companies that are engaged in purposeful collection and cleaning oil for future injections into the heating system. So to find a sufficient number of the desired consistency is problematic.
- High fire risk. If leakage occurs can not ignite. Obviously, this fluid must enter into direct contact with an open flame source.
- Never use the boiler with direct heating.
- Replacing all rubber gaskets and connectors on the oil-resistant, which will be harder to find, as usual they are not equipped with heating systems. In addition, buying them can cost a large sum.
Features
Before pouring waste oil in the system is important to check the many nuances that affect the performance and comfort of the tenants in the future.
Thus, it is known that the coolant fluid, even in the cold. But for an ordinary heating - it is not enough. Warm and the cooled oil is significantly different from each other viscosity. Therefore pipes in the system should have the same diameter. And sometimes on the back bends can be made larger. The fact that the boiler itself is heated quickly, but it does not have time to push oil. In this case, it is even possible to boil.
It is also important to think in advance about the size of the expansion tank. In aqueous systems usually taken 10% of the total volume of liquid. With butter things a little more complicated, because when heated, it increases more than H2O. Despite this level of the system still need from time to time to check and top up if necessary. In such designs, it is recommended to set the tanks, the size of 30% of the total.
A particularly important condition in question spent heating the house and clarified butter is already tight. In most cases, the first time it is impossible to completely avoid leakage. It is considered ideal in places superimposition of a new weld, as gaskets and similar items do not solve the situation. After that, the system starts and is tested for full sealing - in places where there is even a tiny hole, there are small drops. In this case, it is desirable to drain the oil and digest all problem areas. In this case, repeat the procedure need to complete correction system.
You should always pay attention to all the connecting thread. It is important that they are of good quality, especially on the pitch. Otherwise, when heated they may appear small drops. A compound will sometimes even flow. When this seal-like junction will be difficult. You can immediately tell that to solve a problem or tow fumlentoy fail. In some cases help special sealants that can withstand temperatures up to 400 degrees.
Generally speaking, the use of oil in the heating system allows you to leave the room for a long time in any weather. And there is no need to worry about her hypothermia. Furthermore, by using this heat transfer medium can be heated to high temperature battery without fear of failure of the system. But, as elsewhere, there are positive and negative sides.
