The issue of plumbing (Αποφράξεις Καλλιθέα) water pipe insulation is particularly important among suburban property owners. Often in summer cottages and villages, the owners themselves have to worry about many elements of a comfortable stay.
Especially when it comes to homes / cottages with a living room all year round – you can not do without insulation of communications. And first of all, it is necessary to choose and install a heater for water pipes – without water, as it usually flows from a tap, it is difficult to enjoy the pleasures of suburban life.
In our material we will explain why it is worth insulating the water supply and what to look out for when choosing a material for thermal insulation.
Do I have to insulate the water supply?
Often the question of whether it is necessary to insulate the water supply occurs on a frosty morning, when it is already too late – tap water does not flow. In this case the homeowner has no doubt about the need for this event.
Indeed, pipe insulation is not always necessary. It all depends on the location of the house, the climatic conditions, the residence time of the residents and the characteristics of the utilities.
If the family members come to rest only in the warm season, then no insulation is needed. To avoid accidental rupture of pipes due to icy water in cold weather, when no one is in the cottage, you just need to properly maintain the system, preparing it well for the winter.
Does not require insulation and water, stretched to a sufficient depth. According to the rules, water pipes must be properly installed at the following depth: 0.5 meters + depth of soil freezing in a specific area. This is an important condition that must be met so that you do not have to do everything again after the first winter.
Residents of the northern areas have a freezing level of 2.5 m or more. This greatly complicates the process of deepening the pipeline to the desired level. Yes, and such an event will be expensive. Here you can not do without warming up.
It happens that there is no way to create a trench of the required depth for the installation of water pipes. In such cases, insulation is necessary. Another point is the entrance of the water pipe in the house. This plot in cold weather often receives increased attention from many homeowners. Therefore, you must take care of the insulation in time by choosing the right material.
Another place to remember about the pipeline is the entrance of the pipe to the well / well. It all depends on the characteristics of a particular water supply system and the layout of this site. If it is a well and the pipe is immersed in it, then we must not forget about its insulation, choosing a material resistant to ultraviolet rays and subsidence.
Water pipe insulation methods
To prevent frost from damaging the water pipes in a private home / cottage, you need to worry about their thermal insulation in advance.
It is important, even at the communication stage, to consider the insulation options of pipes and not just water pipes. If this is done in time, then the cost will be minimal.
Among the methods of heating a pipe to supply water to a house among homeowners, the most popular are:
- extend the duct 0.5 m below the freezer level.
- use a heating cable.
- insulate with insulating material.
- provides a vacuum.
- buy a finished factory pipe.
- apply several methods at once.
Most of the time, more than one method is used. Thus, if the water pipes are deep, then the area responsible for entering the house must be insulated. Therefore, the best option is chosen to ensure the local water supply system.
The heating cable is widespread due to the simplicity of installation and high quality performance of the functions assigned to it.
Depending on the type of installation, there are 2 types of cables:
The first is placed at the top of the water pipe and the second is inside. It is securely insulated and made of safe materials. It is connected via a thermal shrink sleeve with a conventional cable with a plug or with the machine. Read more about the heating cable for water supply further.
There are many thermal insulation materials on the market. They all differ in their properties, quality, price, installation difficulties and lifespan.
Which one to choose depends on the specific situation.
An air gap method is also often used. It is a water pipe mounted on a cheap smooth plastic or larger diameter corrugated pipe.
Inside, there is free space for hot air to enter from the insulated basement or otherwise heated.
Another option is to buy ready-made insulated pipes of factory origin. Sold fully ready for installation.
They are 2 pipes of different diameters, placed next to each other. Between them there is a layer of insulation. This method of insulation is often called pre-insulation.
The use of many pipe insulation methods is due to the fact that all methods are imperfect and it will not be possible to apply them in all cases. The conditions of use in different households located in all parts of the country are radically different from each other. Therefore, to choose an option that is suitable for specific requirements.
There are alternative methods of thermal insulation that prevent the occurrence of adverse effects. They do not apply in all cases. First, you can remove all the water from the system – no water, no problem. This method applies to houses that are not used in winter. It will help protect the system from damage in case of frozen water pipe.
Second, you can ensure the constant movement of water in the pipe by opening a small tap. This is not difficult to do with permanent residence. But the choice is dangerous – suddenly you have to leave the house for a few days and on the way back there will be a surprise in the form of a damaged water supply.
In addition to the tap hose, it is possible to provide constant pressure to the duct in other ways. For example, use a special water pressure booster pump in the system or add another element – the receiver. It must be cut in the pipe immediately near the pump. The receiver will maintain a constant pressure, which will protect the system from freezing.
