Heating radiators for gas heating: the choice of types of

Often, property owners are not free to choose the type of heating for their home. The circumstances are such that an autonomous system operating on gas becomes the optimal choice.

And then the logical question arises: what material of radiators will be the best?

Battery type selection

Immediately worth noting - the instruction considers the highest quality bimetallic radiators, with any type of heating. They are optimal in terms of cost, functionality and reliability.

Note! Most often, when the gas heating circuit closed. In other words - the coolant in the system does not change. When there are doubts about its quality, then you can bring another water.

Radiators from all materials (aluminum, steel, metal, cast iron, bimetal) are designed for a reasonable working pressure. In public networks, it is not more than 9 bar. In a stand-alone system - usually does not exceed 6 bar. In this case, you can change it.

Instrument Features

1. Aluminum radiators are made of metal with a thickness of up to 1.5 mm. Therefore, they withstand a pressure of 6-25 atmospheres.
2. This makes it possible to use them in low-rise apartments and private houses..
3. Devices are sensitive to water quality, this is their minus. If the coolant does not contain an excess of oxygen and a lot of particulate matter, the batteries are able to serve 10-20 years.
4. Another minus of aluminum is the inability to withstand an excess pressure of more than 25 atm..

Bimetal batteries are free of this deficiency.

1. They hold pressure up to 40 atmospheres without any problems., what happens in high-rise buildings. Therefore, the price of devices is large enough.
2. These radiators consist of pipes from steel-stainless steel, copper and aluminum fins.. Steel is not afraid of low-quality coolant.
3. The design of bimetallic batteries increases their heat transfer.

As for cast iron, it is insensitive to water quality, durable, and can withstand high working pressure. However, its heat transfer is not very large.

Equipment connection

Before connecting the radiators to the gas boiler, it is necessary to choose its model. For heating and providing hot water for small houses and apartments, an optimal wall-mounted unit is optimal. It is compact and light.

The wall speaker is completely ready for connection. Electronics, a binding and a torch are placed in the device case (besides the main knots). Therefore, it’s not difficult to connect it with your own hands.

Note! For normal operation of the heating system, it should be calculated, taking into account the volume of premises and the level of heat loss. Based on the calculations, the column power and the composition of the heating devices are selected.

Connecting the boiler, you should be guided by the regulatory documentation on fire safety and gas supply. They regulate the parameters of rooms for mounting the column and the correct placement of equipment. If the gas boiler does not heat the last radiators, it means that you have not followed the rules anywhere.

After installing the device and assembling the network, the gas supply organization will issue you with a permit to use the system.

Care of the elements of the system

Columns are the combined devices, at the same time both gas and water.

1. In the gas unit fixtures soot accumulates and carbon deposits. They need to be regularly removed. Require special attention to the openings of the igniter and burner (jets).
2. The main problem of the plumbing is scale. In hard water a lot of salt. When the heated liquid evaporates, they precipitate and accumulate on the pipe walls of the pipeline.

Water intake purification

The water intake of the column is at the entrance of the water supply system of the boiler. It is equipped with a strainer for collecting large fractions of sediment and rust that can clog heat exchanger tubes.

There is also a gas supply membrane (when the faucet is turned on).

1. Remove the water intake from the boiler.
2. Remove the screws and open the assembly body.
3. Clean the filter and wash it with a strong jet of water.
4. Inspect the membrane, it should be flat. If this is not the case and it is concave, then the resource of the seal is developed. It must be replaced.
5. Next, screw the cover to the water intake and put it in place.

Heat exchanger care

Now about how to clean the radiator gas column from scale.

1. Unscrew the water (inlet and outlet) tube heat exchanger.
2. Remove the knot and pour a cleansing composition into it using a funnel. The solution recipe is simple: it is necessary to dilute 100 grams of citric acid in 1 liter of heated water.
3. Another way to remove scale from a gas column radiator. It is necessary to dilute with vinegar (70%) in a ratio of 1: 3.
4. Next, you need to leave the tool in the heat exchanger for 8-10 hours, then pour it.
5. If you do not remove the dirt that has fallen off the walls, it will get stuck in the knot tubes. Therefore, it is necessary to wash the exchanger with a strong pressure of water.
6. After it was possible to clean the gas column radiator, it is put in place.

Removal of soot and soot

Gas nodes of the column is forbidden to disassemble on their own, as opposed to water parts. This can only be done by local gas service specialists.

However, you can clean the carbon in the jets, without dismantling the burner.

1. Clean the holes with a thin wire.
2. Sweep the soot with a brush with metal bristles.

Conclusion

For gas heating, you can use all types of radiators. They should be chosen based on the type of your home, as well as the characteristics of the heating system. The video in this article will complement the topic with visual highlights.
