Floor heating is the abbreviation of radiant floor heating. The whole floor is used as the radiator, and the whole floor is heated evenly by the heat medium in the radiant floor. By using the law of heat storage and upward radiation of the floor itself, it is conducted from bottom to top to achieve the purpose of heating. After the floor heating is installed, the ground should be backfilled with pisolite concrete. In the construction of floor heating in home decoration, backfilling is generally carried out by decoration contractors or floor heating construction companies. If we don't pay attention to the construction quality, it will easily lead to the destruction of the floor heating system. So what is the general quotation for floor heating backfill? Next, please have a look with Bian Xiao.

First, the floor heating backfill ingredients quotation

According to the specification, the backfill soil for floor heating is pisolite concrete backfill soil, which is mainly composed of cement, yellow sand and pisolite. Take the floor heating market in Beijing as an example. At present, the price of the stone concrete backfill site is around 50 yuan/m2 (contract and materials). Of course, different construction units are high or low (ranging from 40 yuan to 70 yuan), so the theoretical proportion will not be mentioned. However, at present, the backfilling units are not standardized, and they are basically yellow sand concrete, but there is no pisolite concrete. The reason for this phenomenon is actually very simple. One is that the owner bargains blindly, and the other is that the floor heating company deliberately lowers the price and reduces the material cost in order to grab the order, so it will tamper with the ingredients, so the owner must pay attention to this when backfilling.

Second, Beijing floor heating backfill quotation

1. The price in Beijing can be won around 30 yuan, and the labor cost is about 15 yuan. The smoothness of the light receiving surface is controlled within 5 mm, and the material needs to see how thick you are. Generally speaking, 4 yuan is about 1cm thick. If your house is 4cm thick, it is 16 yuan, and if you add labor, it is 3 1 yuan. Maybe the cost of materials and labor in Beijing is higher, or someone else may prescribe it for you, hehe. After the backfill is completed, the concrete needs to be moisturized and maintained. If it is less than 7 days, you can sprinkle less water and cover it with plastic film. You can walk on it after 2 days, but you can't carry out construction because the concrete strength is not enough. It takes at least 7 days, which is 28 days in specification, but there is no problem after 7 days. Mind you, if you have a wooden floor at home, you must find one with good flatness and ask the floor requirements of the wooden floor company in advance. If your home is a wooden floor and the living room is a tile, there needs to be a height difference of 2cm between the two floors, and the surface of the tile can be roughly brushed, so the labor cost is lower. Do not pay attention! !

2. The backfill cost of floor heating in Beijing includes floor heating pipe, benzene board (insulation board), reflective film, go-kart and backfill (cement sand and gravel, labor cost), and the total cost of floor heating ranges from about 50 to about 100. The above is the price excluding water separator, PPR main pipeline and wall-hung boiler, just a simple floor laying price.
