General home renovation almost 6-7 years, many families will consider redecorating once, then the first time the decoration of the installation of the floor heating, do not reinstall, this is a lot of people's questions, reinstall the floor heating is not like reloading the computer simple. First of all, it is explained that floor heating consists of two parts: the ground and the underground. Wall-hung boilers, manifolds, thermostats are above the ground, and coils and insulation are below the ground. Replacement of parts above the ground is relatively easy. Judging whether or not to reinstall is mainly to look at the parts below the ground, especially to see insulation materials.
1. In the three above-ground boilers, thermostats, and water collectors, the most likely problem is the interface part of the manifold and the filtering device. The life span of these three devices is generally 15 years. Of course, there are also years of poor quality of life, and there are also high-quality boilers with decades of life.
Suggested replacement:
Ordinary single wall-hung boilers are recommended for replacement for more than 7 years. The thermal efficiency is very low, and it is used alone (can not provide domestic hot water), and a water heater must be installed.
The manifold is not equipped with a thermostat and the material is a suggested replacement for steel or even PPR plastic. The use of floor heating is for more comfortable temperatures. The former can't control the temperature very well, and it can't control the temperature in a separate room, let alone control the temperature remotely. The latter has a limited lifetime and the manifold is recommended to use copper.
2. The service life of the floor heating coils under the floor of the regular brand is 50 years, so there is usually no problem in the case of no damage. If the interface is already reinstalled, the interface is a big hidden danger to the floor heating.
Then warm insulation, which is not only related to whether or not to heat downstairs Lao Wang floor heating problems, the pressure insulation and environmental protection of floor heating insulation panels for the past few years is not optimistic, hidden works you know. For first-tier cities such as Jiangsu, Zhejiang and Shanghai, it is recommended that the ground warming before 2012 be resurfaced; the second- and third-tier cities, the proposed resurfacing before 2014; the so-called fine-decorated floor heating is recommended for resurfacing; no insulation boards are used or black poor insulation is used Board or EPS (extruded board is XPS), it is recommended to re-shop. Installation time is an initial judgment criterion. It is better to ask the former owner what the warm insulation is doing.
What should you pay attention to when you renovate and warm up?
1, Do not blindly construct second-hand housing The intractable problem is that there is no pipeline map, blind construction can easily hurt the pipeline. Larger companies now have thermal imagers. About half an hour after the floor heating is turned on, you can clearly see the arrangement of coils below the ground. It is best to simply make a sketch or mark.
2. Since the bricks are not known to be thick (typically 3-5cm), they need to find experienced workers and gently chisel. After the floor tile is fully drilled, do a pressure test. If there is no problem with the pipe, the floor heating can be retained.
3. If the walls and doors are to be demolished or changed, there will be no impact on the floor heating. If you want to build a new light partition, the industry will focus on fixing the top of the wall rather than nailing it on the ground.
4. Since hydropower is renovated, it will surely involve hydropower reform and other projects. This is a bit troublesome. If you do not know the situation, it is best to avoid the ground, and you need to communicate and confirm with the decoration workers again and again to see if the transformation is feasible.
What needs to be done to keep old land warm before use?
1, after the renovation, pressure test.
If the pressure test fails, it is likely that the floor has leaked water.
1. Slow water injection through the water separator and discharge the air in the pipeline at the same time.
2. After water is filled, check the watertightness.
3, using manual pressure pump to increase pressure, the test pressure is 1.5 times the design pressure, and should not be less than 0.3Mpa, not more than 0.6Mpa.
4. After boosting up to the specified test force, stop the pressure and regulate the pressure for 1 hour. Observe the pressure gauge to see if the pressure is off and determine if there is any leakage.
5. After the pressure is stabilized for 1 hour, make up the pressure to the specified test pressure. The pressure drop within 15 minutes does not exceed 0.05Mpa. The ground heating system is not commissioned and it is strictly prohibited to operate. The commissioning work is carried out by the construction unit in cooperation with the project using unit.
2, cleaning to warm and warm cleaning is generally 2-3 heating season once. Commonly used methods for floor heating are: filter cleaning, chemical cleaning, projectile cleaning, jet cleaning, and physical pulse cleaning. Filter cleaning and chemical cleaning are often used together with the last three cleaning methods.
3, system maintenance recommended to find a warm company to do a system-wide maintenance and inspection. Such as wall-hung boiler cleaning, replacement of the water separator gasket, filter replacement, plus protective agent and so on.
