Why is it necessary to make a slight slope when installing radiators? Professional advice

  • Jul 31, 2021

I have installed a huge variety of radiators in my lifetime. Therefore, I even felt like a guru in this matter. Once I was lucky enough to talk to an experienced master who literally opened my eyes. It turns out that I did not know one important nuance.

I would like to note that I had no reason not to trust this professional. He has been working with heating systems for more than a dozen years, so he knows everything about them!

So, this master worked in a 2-storey building with a large area (over 300 squares). At the same time, the ceilings in this house reached 3.5 meters. To heat this property, 26 radiators were required, as well as 1.5 kilometers of pipes for arranging underfloor heating.

When the installation of the heating system came to its logical conclusion, the owner of the house noticed that the radiators were not installed according to the level. Naturally, he had questions. The master assured that due to the fact that one edge of the radiators is lifted up, the heating system will work “like a clock”. And visually the bevel is not too noticeable.

What is the reason

On the side where the air vent will be located, you need to slightly lift the corner of the battery. Since the lines of the radiator and the window sill are not in parallel, the angle of inclination will not be conspicuous. The air will flow into the raised corner, and from there into the air vent.

When do you need to tilt the radiator?

There are currently two air vent options on the market:

  • the first ones work automatically;
  • the second is mechanical.

If the air does not have room for maneuver and cannot be removed automatically, it is necessary to lift up the side of the radiator opposite to the air vent. In this case, it is necessary to remove air using a Mayevsky crane. In each case, you need to focus on the location of the radiator.

If the water displaces air bubbles well, they will easily be removed from the battery, even if you do not make a slope.

If there is a slope, the air will independently flow to the Mayevsky tap, automatically leaving the heating system.

In the diagram below, air hits the highest point. From there he has nowhere to move. It turns out that the presence of a bias is not a necessary moment, but a desirable one.

As a rule, the instructions say that you need to install radiators strictly horizontally. Believe me, a slight tilt will not harm, but will only make it better: air jams will not form.
