How much is a square meter for plumbing and floor heating?
1. The price of installing the whole circulating system should include wall-hung boiler, floor heating pipe, distribution main pipe, insulation layer, temperature controller, auxiliary materials and labor costs, among which wall-hung boiler and floor heating pipe are the most expensive parts. Generally, the domestic wall-hung boiler is about 6000-8000 yuan, and the imported wall-hung boiler is about 1 10,000 yuan. The price of domestic floor heating pipes is about 80-90 per square meter. Joint ventures and imported brands are more expensive, and the price is around 120 square meters. Some high-end brands may cost 400-500 square meters. The prices of distribution manifolds, thermostats, auxiliary materials and other related equipment and materials will fluctuate according to different brands. In terms of labor costs, according to the actual situation and the different installation companies in Shanghai, the quotations are also different, and the prices of regular companies and parallel companies will also be different.
2. The cost per square meter in the circulation system is not expensive. The installation in the circulating system only includes the installation of floor heating pipes, and the cost per square meter is about 100 yuan. However, if gas wall-hung boilers, thermostats, distribution manifolds and some related accessories are included, the prices range from 150 yuan to 400 yuan. However, it is very important to choose brands of floor heating, such as Dedi, Bosch and Dong Qing, which have good effect and high cost performance.
Installation method of water heating and floor heating
1. Before floor heating construction, the ground leveling layer shall be inspected.
2. The water distributor is horizontally fixed on the wall with four expansion bolts, and the installation should be firm.
3. Paste 10mm corner insulation board along the wall with latex, which requires smooth paste and tight lap joint.
4. Lay insulation layer on the leveling layer (such as 2cm thick polystyrene insulation board, insulation coil or imported insulation film, etc.). ).
5. Lay a layer of 2mm steel wire mesh on the aluminum foil paper with the spacing of 100× 100mm and the specification of 2m×1m.. Laying should be neat and tight, steel mesh should be tied with cable ties, and uneven or warped parts should be fixed on the floor with steel nails.
6. The heating pipes (PEX pipes, PP-C pipes, PB pipes and XPAP pipes) should be spaced according to the requirements of floor heating design, and the pipes should be fixed on the benzene board with plastic pipe clips. The distance between the fixed points should not be greater than 500mm (according to the length direction of the pipeline), and both ends and midpoint of the elbow section greater than 90 should be fixed.
7. Check whether the heating pipes laid by the floor heating are damaged, and whether the pipe spacing meets the design requirements, and then carry out water pressure test, and inject water from the water injection exhaust valve for water pressure test. The test pressure is 1.5 ~ 2 times of the working pressure, but not less than 0.6Mpa, and the pressure drop at constant pressure 1 hour is not more than 0.05Mpa, which is considered as qualified.
8. When the side length of local warm radiation heating floor exceeds 8m or the area exceeds 40m2, expansion joints shall be set, with the size of 5 ~ 8mm and the same height as the fine stone concrete cushion. When the plastic pipe crosses the expansion joint, a flexible sleeve with a length of not less than 400mm should be set. In places with dense water separators and warm air pipes, corrugated pipes with a length not less than 1000mm should be used for external protection to reduce the thermal expansion of concrete. Fill the joints with elastic swelling paste (or imported elastic sealant).
9. After the acceptance of the heating tube, backfill the fine stone concrete, and keep the pressure of the heating tube not less than 0.4Mpa. The cushion shall be compacted by manual plastering, and mechanical vibration shall not be used. It is not allowed to trample on the laid pipeline. During the construction period, special personnel shall be assigned to take care of it day and night. After the cushion reaches the curing period, the pipeline system is allowed to release pressure. A filter is installed at the water inlet of the floor heating water separator to prevent foreign objects from entering the floor pipeline loop, and the water source should be clean water.
10. cement mortar leveling, do the ground.
1 1. After the pipeline is connected to the distribution manifold, the system pressure test shall be conducted. The test pressure is the working pressure of the system vertex plus 0.2Mpa, which is not less than 0.6Mpa, and the pressure drop within 10 minute is not more than 0.02Mpa. After the pressure drops to the working pressure, it is considered as qualified.
Water heating floor heating is a kind of floor heating that can often be seen now. When choosing such floor heating, everyone needs to know how to install it correctly. The above is how much is a square meter for plumbing floor heating generally introduced by Bian Xiao, and the installation method of plumbing floor heating ends here.
