Which pipes are better for heating
A single-valued answer to the question:what pipes are better for heating, no. Previously, the best pipes for heating could be easily recognized as stainless steel pipes, as well as galvanized. Compared with conventional metal pipes, their service life was much longer (about once every two years) and ranged from fifty to one hundred years. There were also pipes made of duralumin, which are almost never found. At that time, there were no better pipes than galvanized, because they were not afraid of corrosion. The downside of these pipes was that they could not be welded together normally. And the seam has always been their weakest point. But even then the problem was learned to bypass using adapters and cutting special threads. Stainless steel pipes also suffered from this "disease", the welding places began to oxidize, but at the same time they were easy to cook, and with proper processing it was possible to avoid the appearance of rust.
The fact is that both galvanized pipes and pipes fromstainless steel, although considered stainless, but they still were prone to corrosion, only not as fast as the rest. The huge plus was that their inner surface was very smooth, and due to this they rarely clogged. What could not be said about ordinary metal pipes and pipes of duralumin. In all respects, they were inferior to the first. Metal quickly took corrosion, they were often clogged and their service life rarely exceeded twenty years, and the tubes of duralumin were fragile. In general, both those and others required constant supervision, they needed to be tinted almost every year. By the way, it should be noted that those who thought about which pipes are better for water supply should know that the same pipes are now used for both heating and water supply.
Nowadays, when newtechnology and new materials, thoughts about which pipes are better for heating, and which of them to choose, arise even more often. Below, we will consider pipes made of copper, metal and plastic. Metal-plastic comfortable in work, and they can freely bend in almost any direction, and according to the manufacturers they can last about half a century. True, plumbers claim that no more than 7-10 years. Moreover, not all masters have learned to work with them properly, as a result of which the connection technology is often disrupted.
For most of our compatriotsthe optimal answer to the main "thermal" question: which pipes are better for heating, will be ordinary plastic pipes with fiberglass stuffing. They are very easy to assemble, you can even mount it yourself, and in case of anything you can always replace any part. These pipes are not afraid of rust, they do not need to be painted, they do not need care, they can withstand frequent temperature changes, and, after all, they are very durable. And most importantly, the prices for them are quite acceptable. These pipes have only one small drawback - they do not like to come into contact with cement and lime solutions, which corrode them. True, this does not happen immediately, but for 5-15 years. But this can be easily handled: just before plastering any area adjacent to the pipe, just wrap a part of the pipe with polyethylene. After drying, the sticking residue of polyethylene must be cut off. Copper pipes are also positive in all respects. They can even be embedded in the walls of the house, but they also have a disadvantage, namely, the high cost of the pipes themselves and their assembly. Therefore, those who can afford heating are so expensive, there are no other recommendations on which pipes are better for heating.
So, first you should think about which pipes to choose for heating, then buy them and find a good master. The latter, by the way, is a very important component of successful repair.
