How to calculate the installation of indoor radiators?

Indoor radiators.

The calculation of the installation is: number of radiator pieces = radiator fins.

Heat dissipation = number of columns * heat of a single column = number of room area * calorific value.

The calorific value is different in some different regions and different environments. <>

1. How to calculate how many radiators should be installed in the home.

1. When calculating how many radiators should be installed at home, first of all, you must record the number of rooms where you need to install radiators and how many square meters of each room, and then check the heating area of the single-column radiator according to the radiator you choose. There is a relationship between the heating area of a single-column radiator, and the specific calculation method is that the number of pieces required is equal to the area of the room divided by the heating area of the single-column radiator.

2. In addition, it can also be calculated according to the living area of the house and the heat dissipation of the house, first of all, we first calculate the total heat dissipation required by the house, under normal circumstances, the heat dissipation of the house of the family house is about 60 watts to 90 watts per square meter, and then the radiator of the required model is purchased, for example, the radiator purchased is 100 watts per piece, and the total heat dissipation of the house is 2100 watts, then the radiator required is 21 pieces. <>

2. What are the factors that affect the temperature of the radiator?

1. Some people will think that as long as a few more radiators are put in the room, it will be hot, some factors that actually affect the heat dissipation of the radiator are more, not a simple quantity problem, such as the temperature of the water flow of the pipeline circulating into the water, etc., the heat emitted by the same radiator in different working environments is also different, so if you want the radiator to be warmer, you must first ensure that the temperature of the inlet water is high, and also ensure that the water flow of the pipeline can be better circulated.

2. In addition, even if it is a radiator, in the same working environment, if it is in different rooms, it will have different effects, so the factors that affect the use of indoor radiators include the warmth of the house, the window, the orientation problem, the height of the floor, and the interface mode and function of heating installation. <>

It is calculated according to the specific number of radiator groups, as well as its heat dissipation, as well as the heat and column number of single houses, as well as the calorific value of the housing area.

It should be calculated according to the length of the gas plate and the length of the two inscribed cylinders, which is better and more economical.

This is mainly calculated according to the size of the area in the house, and the number of radiators required is different for different areas.

Install radiators in your home.

Not only is it comfortable and warm, but it can also protect the health of the elderly and children at home. For the installation of radiators, everyone is concerned about the problem, the market is varied, high and low, how much does it cost to install radiators at home? Today, Jin Jin will give you a calculation.

Let's follow Jin Jin to find out.

Installing a radiator is much more than just a set of radiators. The total cost of installing radiators in a home includes 3 costs: radiators, materials, and installation.

Let's talk about the radiator cost first. The radiator on the market is not a whole, and is generally calculated as a "piece".

Usually a group of radiators may have 5, 6 or even 10 radiators, which is determined according to the size of the family, heating needs, etc.

The ** of the radiator is related to the material and profile. The radiators in the guest bedroom are vertical and horizontal, with different heights ranging from 30cm to 180cm, and need to be placed in accordance with the home decoration position. Taking the cost-effective steel radiator as an example, more than 3 pieces are generally sold, and the larger the area, the higher the cost of the radiator.

Then there is the cost of auxiliary materials such as heating pipes. There are common PPR pipes, PB pipes, aluminum-plastic composite pipes, etc., all of which are resistant to high temperatures. In terms of unit price:

PB Pipe》PPR Pipe》Aluminum-plastic composite pipe. PB pipe is about 40 yuan meter; The PPR pipe is about 15 yuan. Aluminum-plastic composite pipes are not recommended, because the connection uses ferrule joints, which are easy to age and leak, and must be surface-mounted, and the pipe spacing is short.

After that, there is the installation fee.

This fee can be large or small, depending on the situation. First of all, it can be divided into two types: open and concealed. Surface-mounted means that the radiators and pipes are exposed to the outside; Concealed installation means that the pipes are buried in the wall or the ground and hidden, and the radiators are still outside.

The concealed pipe is more beautiful, but the exposed installation can save a slotting fee, about 50 yuan.

If the original pipeline needs to be redesigned, it is necessary to dismantle and modify, and additional slotting fees and pipeline costs are also required. The installation fee is about 180 yuan, and each group includes two valves and two butt tubes

After assuming that about 100 square meters of three-bedroom, one living room, one kitchen and one bathroom house, choose the more common steel radiator, living room, bedroom are 180cm high, living room about 20 square meters to 5 pieces, bedroom more than 10 square meters to 4 pieces, plus the bathroom to install a back basket radiator, plus the above installation fee, a total of about 5000 yuan. If it's central heating, the money is all there is. If it is self-heating, you need to add a wall-hung stove.

As a heat source, the cost is about 12,000 yuan.

In this way, I believe everyone knows the approximate installation cost of radiators, of course, the specific needs to vary according to the brand and region.

At present, it is the peak season for home improvement, and the installation of radiators is becoming more and more popular. As the saying goes, interlacing is like separating mountains, and many people are home improvement for the first time and know very little about home decoration and radiators. Does the radiator cost include installation, the radiator is sold according to **, how not to sell according to the group, what does the radiator installation fee include, and so on.

Let's follow the golden flagship flag brother to find out.

Regardless of whether the house is an old house or a new house, whether it has been renovated or undecorated, no matter what radiator brand is purchased, the radiator installation cost will be divided into three parts: radiator cost, pipe cost, labor cost, of which pipe cost and labor cost can be converted into **, and the excess part is calculated separately.

First, the cost of radiators.

This is very easy to understand, radiators will not arrive at home for no reason, people need to pay for it, as for how much it will cost, it depends on how many radiators are needed at home. Under normal circumstances, the radiator is ****, and the ** marked above is a piece**, and consumers can convert the number of radiators according to the heat load demand at home, and finally calculate the actual radiator cost.

Since the user is not sure of the actual dosage, it is better for professionals to come to measure and scientifically set the number of radiators installed.

2. Pipe fee.

The heating system is not only a radiator, but also needs pipes, pipe fittings, valves, auxiliary materials, etc., which are standard accessories for radiators, and users generally do not need to buy, such as the standard accessories of radiators have 1 running air, 1 plug, 4 expansion nails, and 4 hooks. In addition, pipes and accessories need to be purchased by the user, the best of these accessories will be affected by multiple factors such as material, quantity, brand, etc., users can turn to the building materials city and listen to the advice of professionals.

3. Labor costs.

In recent years, the labor cost of the home improvement industry has been higher than a year, and some users want to install radiators by themselves. However, heating installation is not a trivial matter, there is a certain technical content, and we don't have professional tools, so it is better to let professional workers do the construction. Taking into account the actual needs of users, the general installation company will make the labor cost and material cost into the first form, such as the company's **150 yuan group, including labor costs, 6 valves, 2 joints, and aluminum-plastic pipes within 2 meters.

Radiator. The installation is composed of many accessories, such as pipe fittings, valves, elbows, tees, running air, plugs, and expansion screws.

Hooks, etc., which run the wind, plugs, screws, hooks are generally distributed by radiator manufacturers free of charge, pipe fittings, valves, etc. need to be purchased separately, according to the actual use of radiator installation charges, these accessories are affected by factors such as material and brand, we must not ignore when purchasing, the quality of accessories directly affects the daily use and service life of radiators, so as to buy high-quality, big-brand products.

How much does it cost to install a radiator: installation costs.

With the growth of labor costs year by year, the labor costs of radiator installation have also risen again and again.

Installation: 150 yuan group, including two 6-point valves, two joints, and less than two meters of aluminum-plastic pipe; 180 yuan group, including: two 1-inch valves, two joints, aluminum-plastic pipes within two meters, and the excess part is practical and practical.

In addition, if the installation cannot be carried out or not installed due to customer reasons, an empty running fee of 50 yuan will be charged.

The above is a detailed introduction to how much is the installation of radiators and the installation of radiators, I hope it will be helpful to everyone, pay more attention to the installation of a network, and share different home improvement knowledge every day.

Look at the number and size of the specific installed radiators, and whether the pipes have been changed.

Many homes have problems installing radiators after renovations. But every user has a common goal: how to save money by buying fewer radiators while keeping the room warm.

How many radiators should be installed in each room, and how many radiators should be purchased per set. It is closely related to the size of the room. Some rooms have a relatively large total area, so the heating system needs to be adapted to local conditions.

If a set of radiators is installed, the number of radiators needs to be increased to achieve the expected temperature of the room.

If the room area is large, in addition to considering increasing the number of pieces, you can also increase the number of heating groups in the corresponding location to achieve a warm and comfortable effect. Depending on the heat dissipation of the radiator, the number of installations involved in the installation is also different. Some radiators dissipate a large amount of heat and reach the expected temperature very quickly after opening, while some radiators dissipate a small amount of heat and have a relatively small area for heat dissipation.

Generally speaking, when the gold flagship heating system leaves the factory, it will mark the heat dissipation. These values have been measured through countless experiments and have a certain reference value. It is also possible to install several more pieces or a group of multiple pieces to make the room warmer.

First, determine the heat load of the room, which is the heat consumption of the room, including the basic heat consumption of the envelope, the heat consumption of the cold air passing through the gaps in the doors and windows, the heat consumption of the cold air that invades the adjacent rooms, the heat consumption of water evaporation, etc. Just check the heat consumption of the house and you're good to go. The heat load per square meter of a house in northern China is about 100 watts.

We need to determine the size of the room. For example, two groups may be installed in a room of about 20 square meters. This ensures that the room is heated more evenly and faster.

The heat dissipation performance of a group of different components is not an increase in the number of parts, but has a certain effect. Here is a correction factor, generally 6 10, with a correction factor of 1. If the range is exceeded, the number of corrections will be increased or decreased.

The installation of indoor radiators is calculated according to the size of the room and the heating situation of the radiator, which often needs to be calculated according to the heat dissipation of the radiator and the area of the room.

It is calculated according to the overall space and applicability, mainly according to their own needs, and if you want the temperature to be hot, you need to install more.

It will be calculated according to the area of the room, the heating of the radiator, and the size of the gas sheet, so that the heating can be more reasonable, and it can also save costs.

For living rooms and bedrooms, the number of radiators needs to be calculated according to the size of the room. First of all, choose a cost-effective radiator and remember the amount of heat dissipation of each piece;

Divide this heat dissipation by 100 to get the number of pieces needed per square meter, and then divide the room area by the number of pieces needed per square meter to get the total number of pieces needed for this room.

For example: the living room area is 20 square meters, select the radiator with a height of 1800 in Rubens Cézanne Great Waterway, the heat dissipation of each piece is 260W, the algorithm is: divide the heat dissipation with 260W divided by 100 equals the number of pieces needed per square meter), the room area is 20 divided by equals, so a 20-square-meter room needs a group of 8 radiators.
