Having built a house, many people begin to wonder how to make heating in it. It should be noted right away that such an approach is fundamentally wrong, since it was necessary to take care of this even at the planning stage. This is because if you want to install a single pipe heating system with polypropylene pipes, it will not be so easy, and you may have to destroy what has already been done. This concerns not only making holes in the walls, but also shaving the floor, as the desire to make the housing not only warm, but also beautiful, by laying the pipes in such a way that they do not spoil the design of the heated room, is understandable.
Single pipe system
The peculiarity of the one-pipe heating system is that there is a pipe from the boiler, the second end of which again comes to the boiler. Without breaking the main line, radiators are connected to it.
Such heating systems can be:
Both systems can be both closed and open.
Radiator thermostat The classic (most commonly used) is the horizontal pipe wiring. For retrofitting any battery you can purchase:
As already mentioned at the beginning of the article, one of the advantages of a one-pipe system is the ability to hide communications in the floor. This is an important factor, because nowadays there are few who hide heating radiators behind the curtains, and this is not practical, since the air circulation around the batteries is disturbed, as a result of which the temperature on the boiler has to be raised, and this leads to unnecessary fuel consumption.
If there is no counter-slope or height differences in the assembled system, then it can work without a pump.
The Mayevsky crane is installed
After talking about the advantages, need to mention and disadvantages.
Not every person can use computer programs for modeling in a 3D projection of his house, which would undoubtedly be very convenient. Given this nuance, we will consider how to make a plan manually by writing everything on a piece of paper.
When making the scheme, you need to take into account the peculiarity of the installation of the system of polypropylene pipes - it is impossible to make smooth turns in it.
It is important to choose the height of the battery and the number of sections
Determining how many sections will be needed for the room, you need to take into account that each subsequent battery heats weaker, so you need to increase the number of sections of composable batteries (or area, if the radiators are steel).
Soldering of polypropylene pipes
For installation considered in The heating system article will require not so many tools. These are:
All-polymer products are suitable only for water supply. You need to purchase reinforced pipes, the characteristics of which allow them to be used for heating.Best of all, if basalt fiber or aluminum foil is used as a reinforcing layer, then the elongation coefficient of the pipe is threefold reduced, in contrast to products with fiberglass.
Fitting the battery
The first step is to mark the walls for each battery. They need to be installed under each window - this will prevent cold air from flowing to the floor. In order for the battery to fully fulfill its role, its length must be at least 70% of the width of the window opening. It is also important to maintain a distance:
When purchasing batteries, these requirements must be taken into account.
To learn how to find out how many battery sections you need to install for one room, you can read in the article on bimetallic radiators.
Using horizontal markings, you need to mark the places where the fasteners will be installed with such a distance that the installed fastener is between the sections of the installed battery.
It remains to start the boiler and check the performance of the one-pipe system assembled by hand.
