Operation of radiators in questions and answers

We will answer the most common questions regarding the operation of heating radiators.

We will learn how to properly operate heating batteries: turn on the battery, regulate heat, set control valves.

Do I need a Mayevsky crane?

Yes, it is highly desirable to install it on every heating radiator. This is a manual air vent. If air accumulates in the sectional battery, it interferes with the uniform distribution of the coolant. At least twice a year, when the heating season begins and ends, air must be removed from panel and tubular radiators.

What is system test pressure?

According to Russian standards, the test pressure is one and a half times higher than the operating pressure, which is established when the heating system is operating normally. The Rmnt.ru portal wrote in detail about crimping. During it, a pressure test, increased pressure is supplied to the network. If the radiator and the entire system withstood it, then in the operating mode it will all the more function normally. There is also a third parameter – the pressure of destruction, rupture. It is three times higher than the working one! The likelihood of such a situation occurring is low, but your battery should be able to withstand a brief and sharp increase in pressure to such an indicator.

Will a heat-reflecting screen behind the radiator help make the room warmer?

Yes, according to experts, a foil screen placed behind the battery increases heat transfer by about 5-10%. However, this method is only suitable for radiators with a high radiant power component.

Which radiators dry the air in the room less?

Those with a higher percentage of radiant power. For example, in classic cast iron and steel tubular radiators, the convective power accounts for 70% to 75%. The rest is for radiant power. This is the best indicator to create a favorable microclimate in the room. You can find out the indicators of the radiant and convective power of the heating device from the instructions for it – the manufacturer is obliged to indicate these important characteristics.

Do I need to install a filter for the coolant if it is water?

The heat carrier is an invariable part of the most popular heating system in our country with liquid circulation. Most often it is just water. If we are talking about a private house, a cottage, then a filter for the coolant is not needed, because you will initially use distilled or boiled water. It also makes no sense to install a filter for a coolant in a high-rise building – it simply does not clean what is launched into the general heating system.

When does it make sense to put a thermostat on a radiator?

It is advisable to install thermostats or thermal heads, if you have steel or tubular, sectional radiators and a new heating system! Again, new, not worn out. Thermostats are now being installed in new buildings. But in old houses, where the coolant is often at a low temperature, the thermostat will only create completely unnecessary hydraulic resistance. In addition, it makes no sense to put the thermostat on cast iron batteries, they are too inert.

Is it true that cast iron radiators don’t rust?

Yes, they are practically not afraid of corrosion. But we must not forget that in a cast iron radiator there may be parts such as steel nipples and gaskets between individual sections. And now they can start to rust.

Can radiators be painted?

Sure. But first, you should clean the surface, cover with a primer with special additives against corrosion. And choose the right paint, it must withstand high temperatures. Remember that too many coats of paint will reduce heat transfer. In addition, dark objects radiate heat better. Therefore, it is worth abandoning the white color traditional for radiators.

Important! Modern aluminum radiators are painted at the factory with a special powder composition. At home, you cannot achieve this smooth finish. In addition, while the heater is under warranty, it must not be repainted.

How to flush a cast iron radiator?

Flushing is needed if the battery does not work well. Most likely, plaque has accumulated inside due to the poor quality of the coolant of the common building heating system. The radiator should be dismantled, all plugs removed, and transferred to the bathroom. Direct a powerful jet of water inward. This may not be enough; you can use pipe flushing and sewer cleaning products. The radiator must be turned several times, shaking out all particles of the washed off plaque. Yes, it’s hard, because the cast-iron radiator weighs a lot. But it will work better. published by econet.ru
