You have decided to change the heated towel rail. To realize this desire is not difficult, because you have only two options:
- invite the wizard;
- install yourself.
Now you need to decide which heated towel rail will be installed. There are also two options:
- Water.
- Electric.
You do not need to compare them. The choice must be made, starting from the technical qualities of the room, as well as the proximity of the pipelines of hot water or water heating. After calculating the price and determining the complexity of the installation work, give preference to one of them.
In most cases, a water heated towel rail is installed. The price of such devices is comparable to electric ones.
Their main advantage remains the coolant, for the use of which for this purpose it is not necessary to pay.
Buy a heated towel rail in the store. Installing it will not take much time. Just keep in mind that before dismantling the old appliance and installing the new one, the water supply is always turned off.
What tools and materials will be required?
- heated towel rail;
- Consoles
- polypropylene pipes;
- welding machine for them;
- pipe cutting knife;
- fittings and couplings;
- Ball Valves.
Before installing the heated towel rail, you must remove the old one, install the bypass and ball valves, and weld the polypropylene pipes.
Why do many craftsmen choose polypropylene pipes?
First of all, they are light. Secondly, they are not subject to corrosion, cheap. And the most important thing is that their installation does not require a bulky welding machine.
Reinforced with special fiber, such pipes are durable and resistant to high temperatures.
So, we take the heated towel rail that we purchased. Installing it will not be problematic.
The presence of various fittings makes it possible to freely connect polypropylene with metal pipes. Mounting them is very simple. For these purposes, there are specially designed welding devices.
How to connect a water heated towel rail? Its installation is regulated by SNiP No. 204-01-85. The ends of the heated towel rail are connected to the plastic structure by means of flanges. In this case, it is necessary to take into account the slope of the underwater pipe to the heated towel rail. It is necessary to do it along the course of the flow of hot water and maintain in the range of 6-12 mm throughout the entire supply.
Water through the heated towel rail must flow from top to bottom, so the feed riser must be connected to the upper bell.
The rules also govern the maximum indentation that must be maintained between the installed device and the wall. For pipes with a cross section of no more than 23 mm, this is 35 millimeters, and if the diameter is not more than 50 mm, it is 23 millimeters.
In order to free the walls from excessive loads that are present during thermal deformations of hot pipes, the entire system is not fixed rigidly, but on supporting supports (brackets).
After completing the installation of the device, all connections are checked. If they are dry, then everything is in order.
So now you have a brand new heated towel rail. Installation didn’t take much time, did it?
