On the selection and operation of hydronic radiant heating systems

To help you select the most appropriate heating system, we propose the following classification of individual houses and cottages:

  •     Type A - one-story house with a basement and without a basement with a steep roof;
  •     Type B - single-storey house with a flat roof to the basement or no basement;
  •     Type B - two or more storied houses with a flat or a steep roof and a cellar.

For houses of type A is recommended to use hot water radiant heating systems only with vertical risers. Heating systems with horizontal can not be heated attic space with a steeply dipping roof. Hot-hydronic radiant heating system such homes with a basement or without desirable to perform two-pipe with natural circulation of the upper or lower wiring. When installing the boiler in the basement of the chimney height must be at least 10m. In homes without a basement boiler is installed on the first floor, and the system should only be wired from the top.

For homes with a basement of type B should apply hot hydronic radiant heating system with horizontal. The boiler is preferably set in the basement. Due to the fact that the chimney height of these houses are less than 6 meters, it is desirable to use as fuel gas or fuel oil.

For homes without basements of type B is also recommended for hot hydronic radiant heating system with horizontal, set the pot is not recessed, and as a fuel it is desirable to use a gas or liquid fuel.

For the two-storey houses and a type B should be used PEX pipe systems with hydronic radiant heating riser and the top or bottom wiring. In horizontal heating system can not be fully warm all the rooms of the house. The heating system runs with natural circulation, since this is sufficient circulating pressure. Since the stack of these buildings have a minimum height of 10 m, the boilers can run on any fuel.

Hydronic radian heating system (on the chosen system to some extent depend on PEX tubing and wiring) are recommended for use in the homes of the respective types.

Polypropylene pipes and fittings

Although plastic pipes appeared on the Canada market relatively recently, only about 15 years ago, they are becoming more popular, gaining popularity at the expense of clear advantages over metal pipes, which were set before them.

There are several types of plastic pipes. The most popular are: polypropylene tube, followed by plastic, metal, PVC, PEX-AL-PEX and PEX pipe. To mount any type of pipe fittings and requires appropriate tools.

The superiority of plastic pipes including polypropylene, is in a range of properties: durability, cost, non-corrosion, the ability to stretch tubes without loss of quality, lack of reaction on contact with water, ease of installation, environmental protection, lack of sound during the operation of pipes.

A variety of waterproofing materials

Waterproof materials are designed to protect building structures from constant exposure to corrosive and wet areas, often under the pressure of the water. In this regard, the materials of this group must be distinguished by properties such as water resistance, water resistance, durability, and also meet the requirements of mechanical strength, deformation resist, chemical resistance, etc.

The application of waterproofing materials are manifold: it is internal and external protection of underground structures, waterproofing underwater, waterworks, dams, bridge supports, embankments, basins, reservoirs and ponds.

Waterproofing not only protects the surface to be protected from contact with water, but also provides, increases the resistance of building structures against corrosion.

Application of waterproofing materials began in ancient times. Another 4500-5000 years ago natural bitumen, resins used as binders, and waterproofing materials in the construction of Egyptian and Babylonian structures. And these days, artificial (often petroleum-bitumen), natural bitumen and materials from their use are one of the most used reliable waterproofing materials. However, serious competitors of bitumen materials are synthetic resins, polymers and materials based on them.

Waterproof materials are divided on the basis of physical appearance and in:
  • mastic;
  • powder and solutions;
  • roller, leaf;
  • film, polymer membrane;
  • other species

Mastic sealing.

Mastic - a visco-plastic mass obtained by mixing organic binding agents with finely dispersed fillers and special additives, having bonding strength. According to its properties and technology of preparation of mastic little than differ from the adhesives, and only increased viscosity and a significant content of fillers serve as the basis for attributing such an adhesive composition to the category of mastics (adhesives, sealants and adhesives in this chapter are not considered)

Design of PEX tubing heating system

Design of PEX tubing heating system - a process of technical documentation that defines the heat output and heat transfer, system design and heat supply station (boiler room), the diameters of heat, the size of heating devices and equipment parameters, the system cost and other technical and economic indicators.

The process of designing the heating system in full operation includes three stages of selection, design and calculation: the technical and economic calculations, design, working documentation. Often the various stages of design were combined. The design is based laid regulations: All-Russian (federal) and local (regional). (See design costs.)

Key documents for the design of heating:
- State standards (ASTM);
- Building regulations (SNIP)
- Building regulations (CH), technical specifications (TS), technical regulations (TA) or a set of rules (SP) - Construction equipment catalogs.

The initial data for the design of the PEX tubing heating system are:
- A source of heat;
- Purpose, planning and construction of the building;
- Technological design and mode of operation of premises;
- Location of the building at the construction site;
- Climatology areas.

Design the PEX tubing heating system consists of four main parts: the calculation of thermal power, choice, design and heat-hydraulic calculation.

What kind of flooring you choose?

When repairing the apartment is very actual question of what kind of flooring to choose from. After all, the correct solution "sexual problem" depends on just how impressive it will look design solution throughout the apartment. It is not true that type of floor covering can spoil everything, and redo the floor often means - to remake the entire repair.

Therefore, we decided to help you sort out this issue, having considered all the popular types of floor coverings in different environments. Let's start from the beginning.

Carpeting. There are two main types - carpets and floor coverings. Carpets have a fixed size, and tend to occupy not the whole floor surface.

Very impressive look designs, in which the classic interiors to the floor or putting expensive Persian carpets, Chinese handmade from natural materials (mostly wool or silk). Solutions, to put it mildly, is not cheap.

If you decide to save money and buy a carpet factory near Moscow, it is important to pay attention to the picture. It should not be pretentious, or you may be like our grandmothers, who install rugs of this type on the wall.

If you really really want to put on the floor beside the bed rug, and in the pocket is not too loud ringing, then go to Ikea and buy a monotonous blanket of pure wool. Although he would not be evident.

Today, more common solution when choosing a carpet floor. Going even a mid-sized store, you will realize that the choice of carpeting today are more than rich. The main difference between a rich assortment, in addition to the color and size, is the material of which it is made.

If none of your family is allergic to wool, the wool carpeting on the basis of natural jute not only for many years will you please the eye but also retain the maximum warmth and comfort of home. But the series models of wool carpet is a significant drawback - they are all fairly similar and more conservative than the eye.

How to Buy Safe boiler

It is well known, the heating processes require constant surveillance here involved the coolant, which is heated to high temperature and pressure goes through the pipes, as well as different types of fuel to their individual physical and chemical characteristics. Uncontrolled heating system can be a source of danger. Its main factor is the fuel that is combustible, which is burned to produce heat. In accordance with the physical condition of the fuel divided by the solid, liquid and gaseous. By type of firm it is wood, peat, oil shale, and coal. By liquid - crude oil, petroleum products and fuel oil are different. For gas - natural and industrial gases blast, coke oven, generator, etc.

Boiler Expansion Tanks

Under any type of fuel developed specialized thermal generators (boilers) for heating systems, personal. Statistics show that the total volume used in our country, more than half the boilers are gas, and another third - on diesel fuel, about 10% - Electrical and about 5% - solid. Taking into account the fact that most of them operates on gas, but also that it is the most promising type of fuel, we analyze the composition and application of advanced automation control gas heat generators. That it offers a safe and reliable operation. Also in this article we consider the requirements for personal heating systems, working on gas equipment.

Hazards in use

Natural gas due to the low cost of the most beneficial for individual heating, because it has high consumer properties. But the physical and chemical properties of the fuel need of careful attention to fuel the organization process. Explosions of domestic gas, gas poisoning or its combustion products from excessive concentrations taken in closed spaces - all potential hazards
