IV. the same heating pipeline will not be allowed to have a connector for the next procedure caused heated pipe damage, subject to the approval of the audited before implementing remedial connectivity while on the completion of the figure, the record clearly brought to the callout
V. pipe(PE-RT) in laying process must not have a connector.

Question 7: how to warm the engineering acceptance
A: the heating engineering (stock room) of acceptance must, in accordance with the relevant water industry standard pressure test, and to keeping pressure maintenance (about 0.15 MPA) and equipped with pressure gauge, mainly in order to better protect ground coil, once the man-made damage can detect and repair.

Question 8: there are several floor heating type
A: filled with fluid-floor heating, floor heating, radiant floor heating fengshanshi

Question 9: are there any install heating faults
A: the shortcomings must find professional company, otherwise it is difficult to ensure that pipe quality, in the event of leakage, downstairs, the floor was scraped resurfacing.

Question 10: in the bathroom floor heating can be done?
A: Yes, but generally not covered. Because the bathroom more groundwater, insulation Board and cement are slit, easy ponding, on heating effects and waterproofing are bad. If you really want to do, but after must be waterproof and water and

Question 11: the floor heating system service life?
A: heating system service life of the buried pipe service life, because you can replace the aerial parts, therefore, to warm the EAC is the key to life, now used for floor heating systems meet the standards of tubing, design life amounts to 70 years, real life is more than 50 years, the heating system is quite basic and building life.

Question 12: the operating cost of floor radiant heating?
A: each House of the specific heat load, external heat and internal heat gain will be different, and thermal insulation and lighting materials, as well as hot water pipe with integrated performance will vary, as well as to the reasonableness of the thermal load calculation will greatly affect the operating cost of floor heating. Through the science of design and the use of standard material, Shanghai area users per square meter lot in 0.15 — 0.25 Yuan/day or so (natural gas or gas). If the design is not reasonable or use low standard material will reduce acquisition costs, but would greatly increase the running costs.

Issue 13: warm the selection of various composite wood flooring, wood flooring, solid wood flooring should pay attention to?
A: in General, should not be grasped to thin, thick, green performance good heat resistance good principles, in the choose when the selection of floor coverings materials have a strength of the brand, product manufacturers,it is best to choose a dedicated floor heating. In addition, the installation of floor heating special floor there is a need to be careful about is the mat, be sure to use geothermal dedicated paper mat, this mat has thermal soon, no distortion, and other characteristics, not the ordinary foam mats and foam mat heat slowly, but the long-term effect of high temperature harmful gases under easy, a health hazard.

Issue 14: use of floor heating, floor will not be deformed?
Answer: not in such a context. To warm the floor surface temperature in 28 degrees, East China summer indoor temperature to 25 degrees centigrade, theoretically the vast majority of floor without problems, but for insurance purposes and heat transfer performance reasons, it is recommended that users have a manufacturers warranty of floor tiles, stone, high-grade PVC flooring, carpet and floor heating special many hardwood and laminate flooring.

Issue 15: Shanghai with electric heating or warm water heating?
A: plumbing heating belonging to cyclical flushing, gas boilers, also can supply all kinds of household water demand, the disadvantage is that the installation is a bit complex, pipeline treatment is not good and easy to scale up, repair and maintenance trouble points, heat slowly, very concentrated.
Heating heat fast, easy to install, as compared to the water that you are installing a boiler, resources are not wasted any time cut off, the heat concentration. The disadvantage is that resources faster, if a power outage will be in trouble, there is a security risk, it is necessary to pay attention to the brand and post-sales

Issue 16: home heating system which most major categories? an integral part of each?
Answer: there are water heating, electric heater. If your home heating area in more than 32 square meters, bathroom more appropriate, especially in the bathroom, the children's room, cloakroom, etc., heating of faster than plumbing heating speed. Plumbing components typically fireplace + water + temperature control system, of course, if you want to heat up faster, so you can add the radiator and heating is relatively simple, it generally consists of heating cable and thermostat.

Issue 17: my home heating too hot?
A: warm too hot for various reasons, such as the heating water temperature through the high, not after a heat loss calculation, heating coil, too dense, and other factors related to the simple way is in between the two competent road into water separator with a short circuit valve, so that part of the water not directly through water separator, the returned several times over regulation, regulating valve switches to a suitable temperature, or you can install a control valve, which regulates temperature control valve to control the room temperature.
