A, geothermal installation specifications and process
1, geothermal installation step is to lay the floor heating space to do layout design, we need to draw a detailed floor heating installation schematic.
2, pre-construction preparation: to clean up the construction site, but also need to confirm that the kitchen, bathroom has been done waterproof treatment. In the construction process if the waterproof structure is damaged, we need to do a good job of waterproofing again.
3, the installation of boundary insulation tape
Process specification: boundary insulation tape 8 ~ 10mm thick, 50 ~ 100mm wide polystyrene slats, can also be used in composite film insulation products, in the installation of the system added. Normal boundary insulation tape is allowed 5mm of compressibility.
4, the installation of insulation board
Process specification: to use the thermal resistance of the better XPS extruded polystyrene board, thickness 2mm, can be laid on the foundation steel plate.
5, the installation of metal aluminum foil reflective film
Process specification: in the floor heating pipe installation before laying on top of the insulation layer.
6, laying steel mesh
process specification: composed of ф3 ~ 5mm steel, to be installed on top of the metal reflective film can be fixed firmly.
7, the installation of ties, PERT tubes
Process specification: ties with fine lead wire instead of fixed binding. You can use PERT pipe, PERT pipe fixed between the steel fine mesh, spacing control in 50mm, the appropriate encryption at the bend. Is to be connected to the distributor at the joints of each loop circuit.
9, protective casing
Installation process specification: available insulation pipe or plastic protective casing, which can play a protective role in insulation.
10, the installation of temperature control system
process specifications: sub/collector pre-buried by the decoration company to set up power outlets, while the pre-buried signal line in the thermostat to the position of the water distributor:
11, installation of sub/collector (box)
Installation process specifications: should be equipped with water injection, water discharge device, each loop should be manually balanced device. Split / collector installation should be tightly connected with the floor heating pipe, and in connection with the riser (main) pipe between the installation of ball valves and automatic exhaust valve.
12, pressure test experiment
Two, geothermal installation of the top ten precautions
1, floor heating and renovation synchronization
Floor heating is a hidden project, paved under the floor. After walking through the water and electricity to start installing the manifold and laying pipes, the late stage is to install the hanging fireplace after the renovation, so it is very time-saving.
2, laying details to pay attention to
Floor heating piping arrangement is very complex, be sure to ask the teacher to do the design and installation.
3, concrete filling
Concrete filling is to protect the floor heating pipes and make the ground temperature uniform construction. Supervision, pay more attention, must use fine stone concrete, stone particles diameter should be less than 1cm, cement mortar volume ratio of not less than 1:3, concrete pouring height 4cm.
4, the ground can not be punched
The ground can not appear to be punched, hitting nails, to avoid leakage of the floor heating coils, resulting in water leakage. Renovation later if perforated to the floor heating rework up is very cumbersome.
5, do not place a large area of furniture
If the floor of the placement of a large area of furniture, will directly affect the effect of underfloor heating, so try not to put a large footprint of the home
6. To check the sealing of the underfloor heating system before paving is good.
7. The ground should be kept dry, the ground moisture content of less than 1.5% is good; if the indoor humidity is very large, it will directly affect the heating effect.
8. Expansion joints should be left between the floor and the wall
9. 24h after the installation is completed before normal use.
Three, floor heating installation price how much a flat
Now on the market is mainly floor heating is roughly divided into water floor heating, electric floor heating these two. Electric floor heating is divided into heating cable floor heating, electric film floor heating, carbon crystal floor heating.
Heating cable floor heating has a single-conductor and double-conductor style,
Double-conductor floor heating prices in the 300 yuan ~ 380 yuan - square meters
Single-conductor floor heating prices in the 130 yuan ~ 170 yuan - square meters.
The price of electric film floor heating is around 120 yuan~180 yuan-square meter
The price of crystal floor heating is around 140 yuan~200 yuan-square meter.
Water underfloor heating price at 80-180 yuan - square meters or so, underfloor heating but also with the installation of boilers, water collectors, insulation and so on.
Domestic wall-mounted boiler about 6000-8000 yuan or so
Entrance wall-mounted boiler about 10000 yuan or so
The above is about the geothermal heating installation specification and process, geothermal heating installation of the top ten precautions, geothermal heating installation price of how much a square meter of the whole content, I hope it can help you to understand the geothermal heating installation, more knowledge of the renovation, renovation company evaluation, Decoration cases please continue to pay attention!
