We will tell you how you can make heating registers with your own hands from metal pipes.
Radiators, batteries are part of the general water heating system of any home. The price is usually quite high, and some homeowners are considering saving money.
Homemade heating register
The heating register is a fairly simple design of several pipelines running horizontally or vertically. They are connected to each other by jumpers. Registers are made of smooth steel pipes, which can be round, rectangular and square. Sometimes they are combined with each other, but usually pipes of the same shape are selected for one register.
Pipes for heating registers can be made not only of carbon steel. Galvanized steel, stainless steel, aluminum, brass and copper are also used. However, pipes made of such metals are more expensive, in addition, they are much more difficult to assemble and process with your own hands.
The simplest registers that can be made independently from a profile steel pipe are sectional, and there can be only two sections, as well as coil, in the form of the letter S.
In sectional registers, sections of shaped pipes with plugs at the ends are located parallel to each other. They are connected to each other by pipes of a smaller section, which ensures that the register is filled with a coolant from both sides.
Important! The closer to the edge of the profile pipe transition jumpers are installed, the higher the heat transfer of the sectional structure will be.
There are also jumpers in the coil register, but they are deaf and are needed only to ensure the rigidity of the entire structure. The liquid flows through the S-shaped rows of curved pipes.
Basically, to create heating registers with their own hands, profile pipes with a diameter of 80 to 150 millimeters are used. First you need to calculate how many sections in general and what size coil you need to heat a particular room. We will give you a scheme that professional designers may call simplified, but it will suit home craftsmen.
First, we calculate the volume of the room, remember the formula from the school course: V = L * W * H, we multiply the length, width and height of the room.
Now we need to find out how much heat in W we need for this room:
Qd.t = V * k * (Tvn – Tnar)
In this formula, V is the volume of the room, k is the heat transfer coefficient of the walls, Tvn is the temperature inside the building, and Tnar is the temperature outside.
We calculate how much heat will be emitted by one register:
Qр = q * L * (1 – n)
Here q denotes the heat flux from each pipe running vertically or horizontally. This value is approximately 20-30 W / m. By L we mean the length of the register pipes in meters, and by n – the coefficient of unaccounted heat fluxes. For metal pipes, this figure is 0.1.
Now it’s easy to calculate the number of registers: N = Qp.t / Qp.
Important! The distance between the register pipes affects its heat transfer. Add 50 millimeters to the height of the profile pipe to obtain the optimal distance between the rows of the structure.
In addition to the pipes for the register themselves, you will need branch pipes, a steel sheet for plugs, fittings (angles), as well as bends that must match the diameter of the selected pipe. Don’t forget about the Mayevsky crane!
We recommend using a circular saw to cut the pipe to the desired size. Do not forget that you will need to cut holes in the sections for connecting jumpers, mark in advance where they will be located.
All metal parts are connected to each other using a welding machine; to give the register a more aesthetic look, it must be painted with a special paint for radiators.
We admit that home-made heating registers are most often used to heat garages, home workshops, greenhouses and other utility rooms. Such designs allow you to save money, but factory radiators are still more often used for residential premises. published by econet.ru
