What to rely on when choosing the type of radiator for a private house
One of the advantages of a private house is an autonomous heating system, which is calculated and installed according to the individual desire of the owner of the house. When asked which radiators are best for a private house, it is easier to answer than when choosing radiators for an apartment connected to the central heating network of the microdistrict. Unlike the central heating system of city apartments, the closed system of a private house has the following positive characteristics:
- works at low pressure and there is the possibility of creating an enabling operating environment;
- here there are not such huge hydraulic hammers, thanks to this the range of choice of radiators offered by the market is significantly expanding;
- at observance of technical conditions of acidic water balance, the list of radiator selection is quite extensive;
Taking into account the above-mentioned positive characteristics of an autonomous home heating system, the main emphasis in the choice of radiators for it must be made on the maximum heat transfer coefficient and good price-quality ratio. By and large, any radiators, steel, aluminum, bimetallic and even cast iron, can be used to operate in a closed home heating system. But some points still need to consider which ones to read further.
Below, we will consider all possible types of heating radiators for a private house, and try to identify the best options.
Features of the use of certain radiators for the heating system of a private house
Tubular and panel steel radiators
1. Panel and sectional steel radiators - the most budgetary radiators for heating a private house. They have good heat transfer characteristics, are compact enough and fit well into the interior. Depending on the type of execution, there is a choice of different connection options, to the heating system of the house. In private houses with wide window openings, the panel radiator covers the cold airflow and prevents the appearance of drafts.
For those who are looking for good heating radiators with affordable cost - this is an optimal option for use in your home.
2. Tubular radiators - on the price plate stand above the panel and sectional radiators. According to technical characteristics, they are approximately equal, mark-up is mainly due to a more refined appearance with claims to design elements. It is also convenient to use tubular radiators for drying things, which is important in families with a large number of children.
Design options for tubular steel radiators.
When choosing a steel radiator for a private house, we get the following advantages:
- The affordable cost combined with a good coefficient of efficiency
- Low oxidation from poor water
- Long service life
- Convenient overall dimensions and light weight
The disadvantages are the following:
- Not too harmonious design, which first of all shows that it is still a heating system, and not an element of decor.
- Also, despite the manufacturer's warranty, it is advisable to clean the steel radiators every 3 years to prevent the process of slagging the heating system at home.
- Another significant drawback of steel batteries is the need for constant filling, otherwise there is rust, capable of killing the radiator for several years.
Aluminum radiator has been widely used for private house heating systems. Such popularity is explained by modern design and high thermal capacity. The price range of aluminum radiators is extensive, it all depends on the manufacturer. The cheapest ones are the radiators of Russian manufacturers, judging by the feedback of users it is better to take foreign analogues which are much more expensive.
Aluminum radiators with different axle distances.
If you select an aluminum radiator for a local heating network of a private house, then you need to observe a number of fairly important conditions for selection and operation, which are provided below:
- The aluminum radiator is very sensitive to the parameters of the circulating fluid. It is important to comply with the desired level of acidity of water, otherwise aluminum can collapse in a few years.
- The high thermal power of aluminum radiators has the opposite side. A warm air stream rises too quickly to the top and often there is a temperature drop, between the ceiling and the floor. Therefore, when choosing aluminum radiators, it is necessary to make an accurate calculation of the area of the room, otherwise the floor can be cold.
Affordable price, good design and fast heat dissipation is the whole secret of the success of aluminum radiators. Enough good radiators for heating a private house. With strict adherence to the above standards of choice and operation, they will last a long time with good heat output.
The upper point of evolution of radiators is a bimetallic radiator with a stated lifetime of 40 years. Bimetal is a combination of two or more kinds of metal in one product. Bimetal radiators inside are made of steel, and from the outside are covered with aluminum fins.
Quality bimetal radiators are necessarily covered with an anti-corrosion primer, not only from the outside, but also inside. It is able to withstand the pressure of 20-35 atmospheres and does not require special technical conditions for circulating water.
Bimetal radiator incorporates heat transfer of aluminum and corrosion resistance of the best alloys of iron.
The reverse side is a high cost, for the average inhabitant of our country, it is inaccessible to roads. There are also cheap models on sale, but there is only a bimetallic name in them, if you decide to purchase such a radiator, you should carefully approach this issue in order not to buy the fake of the lowest quality.
The use of bimetallic radiators in private house heating systems is not entirely appropriate because of the high cost. Yes, they have much greater strength than the aluminum and metal radiators discussed above. But at the beginning of the material, I already mentioned that in the local heating network there is not and can not be high pressure, as a rule it is 2 to 3 atmospheres, and therefore there can not be powerful hydro-blows here either. So it turns out that the advantages of this radiator in the form of increased strength in this case is not appropriate to consider.
Cast iron radiators
The first cast-iron batteries began to be used in tsarist Russia, more than 100 years ago. Until now, in Soviet-era houses, you can find a cast-iron radiator with 50 years of experience.
Section of the cast iron radiator type MC.
If the aluminum radiators quickly heat up and quickly cool down, then with the cast-iron batteries all the way around. The residual number of heat preservation at the cast iron radiator is 30%. On the other types of radiators considered, it does not exceed 15%. This allows to significantly reduce the cost of gas for heating a private house.
Resistance to corrosion is very high, the performance of cast iron batteries in old houses, an undeniable proof of their durability and reliability.
If there are doubts about the design, the modern market can boast of exquisite decorative solutions that can brighten the interior of any house or apartment.
The cost of cast iron radiators is higher than that of their aluminum and steel counterparts, but much lower than bimetallic heating appliances.
The only drawback of cast-iron batteries is their too heavy weight.
Table: Comparison of the operating pressure and the application of different radiators
|Options||Working pressure, Atm.||For a private house||For an apartment||Cost|
|Steel panel||6 - 10||YES||NO||Low|
|Steel tubular||8 - 15||YES||NO||On decorative models very high|
|Aluminum (sectional)||6 - 25||YES||NO||Low|
|Bimetallic||20 - 30||YES||YES|| The radiators of the Russian company Rifar and Chinese manufacturers are average. |
European producers have a big price.
|Cast iron (sectional)||6 - 9||YES||YES|| On the model, MS and others like them are low. |
On decorative models, the price is high.
So we reviewed all the common radiators, which it would be better to solve in a private house, using this article as a clue rather than a guide to action. As you can see, any radiators for heating a private house require certain operating conditions, and they should be chosen taking into account the general technical condition and the possibilities of the heating system as a whole. Much depends on the budget, when choosing any type of batteries, you can find a middle ground in terms of technical characteristics and price range.
In my opinion in this case it is most advisable to consider two types of radiators: panel steel radiators or aluminum ones. But still, if you compare them with each other, then probably the steel is still more practical, reliable, efficient and cheaper.
