What materials are needed for laying water underfloor heating?

The materials required for laying water and floor heating are: heat source equipment, heating main pipes, water collectors, temperature control systems, ground structure layers, insulation boards (extruded plastic boards or benzene boards), reflective films, floor heating nails, steel wire mesh, boundary insulation strips, stainless steel hoses, ball valves, elbows, direct, etc. Water underfloor heating is a heating method that provides heat to the room through the heat transfer of radiation and convection from the ground.

The water and floor heating system can be controlled by rooms and households, which fully saves energy and operating costs, avoids unnecessary waste, and will not make noise or dust, which is very environmentally friendly and energy-saving. In addition, if the main engine adopts the method of air source heat pump or ground source heat pump, compared with the traditional fan coil unit heating, the water and floor heating water supply and return temperature is lower, the operation efficiency of the unit is higher, and the two-stage energy saving is realized.

These materials are generally required for the installation of water underfloor heating:

1. Floor heating pipes.

In accordance with the requirements of national and international product standards, the raw materials for the production of plastic pipes and plastic pipe fittings for cold and hot water must be in accordance with the provisions of GB T18252-2000 "Determination of Long-term Hydrostatic Strength of Thermoplastic Pipes by Extrapolation Method for Plastic Piping System" and pass the qualification judgment of special materials for pipelines. Each raw material manufacturer must make a creep failure curve that meets the highest strength reference curve according to the product standard of floor heating pipes, in order to prove that the raw materials sold are qualified. Regardless of the type of pipe used to lay floor heating, only the use of raw materials that meet the requirements of product standards, and the production equipment and technology are reasonable and produce qualified pipes, through the correct design, installation and use, can reliably ensure the service life of plastic pipes for floor radiant heating for 50 years.

2. a thermal insulation board.

The insulation board is an extruded polystyrene thermal insulation board, which is a rigid foam board made of polystyrene resin as raw material plus other raw materials and polyinclusions, heated and mixed while injecting a catalyst, and then extruded and pressed out for molding. Its scientific name is extruded polystyrene foam for thermal insulation (XPS for short), XPS has a perfect closed-cell honeycomb structure, which makes the XPS board have extremely low water absorption (almost no water absorption), low thermal conductivity, high compressive resistance, and aging resistance (almost no aging decomposition phenomenon in normal use).

3. Steel mesh. Laying steel wire mesh sheet on the surface of the insulation layer with nylon tie to fix the pipe, the characteristics are that the construction speed is relatively fast, the positioning is accurate, the overall effect of pipe installation is good, the heat dissipation speed is accelerated, and the ground is prevented from cracking, and the steel wire mesh must be placed on the pipe in the middle of the concrete.

4. a water collector and distributor.

The water collector and distributor, also known as the water collector, is a water flow distribution and gathering device composed of a water collector and a water divider. A water separator is a device that disperses one inlet water into several outputs, while a water collector is a device that gathers multiple inlet water into one output.

5. Reflective film.

Reflective film is one of the types of floor heating paving, which is usually made of vacuum aluminized film and other materials with colored printing grids, polyester film and glass fiber composite processing. The role of reflective film in floor heating is mainly to prevent heat from being lost from the ground, so as to effectively improve the heat reflection and radiation ability and ensure the constant indoor temperature.

Hope the above is helpful to you.

Water floor heating laying and materials and construction sequence up to 7 steps:

1.The bottom layer is paved, and the insulation layer (extruded plastic board, benzene board) is laid

2.Cover with three kinds of reflective layers (kraft paper, non-woven fabric, EPE).

3.Stencil (5cm galvanized steel mesh, 10cm steel mesh, 20cm steel mesh).

4.There are two kinds of water separators: single ball valve and double ball valve

5.There are two commonly used models for coffin laying (Pert, PEX), and the commonly used brands are roughly (Korea LG, Jinde, Fishite, Weixing, Rifeng).

6.Pressure test water, the first pressure (minute pressure drop for qualified pressure pressure during backfill must be maintained 7Backfill (sand, bean stone, cement).

Hello, are you talking about geothermal paving? Geothermal needs 6 points of PPR pipe or PRT pipe (red), lint needs to be used as the bottom, but there is no essential difference between the two pipes themselves, about the same thickness, and look at how big your home is 80-100 square meters of 7-8 column water separator After laying out the pipe, sprinkle pebbles, denser better, and then press 6-8 is enough, and finally cement pouring.

PE pipe 20, there is also a heat shield underneath.

The materials required for laying water floor heating mainly include floor heating pipes, water separators, heating cables, controllers, wall-hung boilers, etc.

Floor heating pipes: Floor heating pipes are the core components of the water floor heating system, and their main role is to circulate hot water into the floor heating radiator, so as to achieve heating. Floor heating pipes are usually made of Pertuline, PEX, PB and other materials, and the specifications are DN20, DN25, DN32, etc.

Water separator: The water separator is an important component in the water floor heating system, which is used to distribute hot water to various floor heating radiators, play the role of distributing hot water and balancing water pressure. Water separators are usually made of stainless steel, copper, plastic, and other materials.

Heating cables: Heating cables are heating elements in water floor heating systems that are used to heat water inside the floor heating radiator to achieve heating. Heating cables are usually made of conductive materials and are divided into single-core cables and twin-core cables.

Controller: The controller is the control center in the water floor heating system, which is used to control the water temperature and the switch of the floor heating radiator. The controller usually adopts an intelligent control system, which can realize functions such as timing switch and temperature adjustment.

Wall-hung boiler: A wall-hung boiler is a heat source device in a water floor heating system that is used to heat hot water to achieve heating. The wall-hung boiler usually adopts gas or electric energy heating, which has the characteristics of energy saving and environmental protection, fast heating speed, etc.

In addition to the above materials, laying water floor heating also needs to consider the floor heating radiator, installation costs and other issues. When choosing a floor heating system, you need to choose the right system solution for you according to your needs and budget.

There are many types of flooring on the market now, including solid wood flooring, laminate flooring, etc., generally speaking, composite flooring is more suitable for geothermal flooring. Because the standard thickness of the geothermal floor is 6-9mm, the thickness of the composite floor is mostly 6-9mm, of which the laminate floor is mostly 6 8mm, and the three-layer solid wood parquet is 8 9mm, the heat transfer performance is better, and there is a layer of aluminum oxide aluminum oxide on the surface of the Zen beam imitation, this wear-resistant layer is conducive to the rapid diffusion of heat on the surface. The solid wood floor is generally about 2cm thick, and the keel should be played when installed, if it is used as a geothermal floor, there is air between the floor and the ground, and the thermal conductivity of air and wood is very low, so that the heat is not easy to be conducted to the surface, which will lead to the waste of heat, the surface temperature is uneven, and the temperature difference is obvious.

And the laminate floor is pressed at high temperature, and the internal moisture content is very small, so the floor will not be deformed due to the loss of moisture. The multi-layer parquet is staggered horizontally and vertically between each layer, and there are dense anti-deformation grooves on the back, which decomposes the stress generated by the heating surface, so the amount of deformation is small. Solid wood flooring has a high moisture content and is prone to cracking when heated at high temperatures for a long time.
