Whether it is heating or floor heating at home, install one! Install one! Never regret series
Starting from this article, plans to use three articles to sort out the heating system about "heating", different types of purchases and avoid pits , , such as radiator , electric floor heating, water floor heating , and central air conditioning + water module heating system.
This is a very complex project. It is called "HV system" in the industry. It will involve electricity use power, whether the gas company allows it, pipeline design, installation and laying, backfill finding equality. belongs to the hard-install hydropower stage, and it will start .

Whether you are unfinished house collection, acceptance of fine decoration houses or renovation of second-hand house heating, I advise you to "save money" in this link. Save a little, and the heating effect in the later stage will be greatly reduced. It is better to "make a good budget and try not to be cheated."
There are no real big brands in the traditional sense. Only some relatively famous brands and miscellaneous brands from Germany, Japan, and domestic products are fighting in the industry. It basically depends entirely on people's industry. The so-called "three points to buy in you, seven points to install in people" is the reason.

"On the comfort of warmth", it still has to be floor heating
The first question to consider for heating is: "Do your home be municipal heating or planned to be self-heating?"
Basically, every brand asks you this question first.

In fact, Xiaofaner has personally experienced every heating method for at least one month.
In terms of the comfort of the body: wall-mounted air conditioners are not as good as radiators; radiators are not as good as floor heating.
Radiator brings "straight men's heating": those who are close are warm, while those who are far away are almost inspiring;

floor heating is more "scumbag": as long as you are on my territory, the rain and dew are evenly affected, it is still from bottom to top;
If you have a sufficient budget, you and I understand the happiness of choosing a scumbag~

"Hot air goes up, air conditioning goes down" This is the basic thermal cycle principle. From this point of view, floor heating is more in line with the natural laws and is better in natural comfort .
Water floor heating VS electric floor heating
Inside the floor heating, there are also water floor heating and electric floor heating , just like covering a blanket on the floor, one is a blanket made of water + pipes, and the other is a blanket made of cables; the water pipes are thicker and the cables are thinner.
Photos Zhufaner self-photography, ZuoShui floor heating Right electric floor heating
electric floor heating = cable 1cm + insulation layer 2cm + control system (panel)
water floor heating = heat source + pipe 2cm/1.9cm/2.3cm + insulation layer 3cm + control system (panel)
From the perspective of occupying layer height , electric floor heating has more advantages. It does not lay backfill layers, only 3cm is needed; while water floor heating requires at least 5cm, and every 1cm of layer height cannot be wasted! !

electric floor heating can be bought, be careful to avoid pitfalls
But water floor heating is still the mainstream in the domestic market. Why?
First, it entered the Chinese market early and was first accepted by design units and government promotion;
Second, it is electric floor heating too well! Note that it is not that its technology is immature, but that the domestic market has ruined people;
I heard that it is profitable and rushes to build cables and wires, regardless of radiation, standardization, etc., and make quick money. As a result, the market was disrupted. over-marketing (a hard-hit area of fake foreign brands), and it was the ordinary families who were injured.
, then I won't buy it~

Actually, everyone can rest assured buy electric floor heating, the key is to avoid the following pitfalls :
· basically depends on the cable brand to buy electric floor heating. Try to choose joint venture , such as Next , Danfoss, and Wen Fei; domestic products can be viewed as Anze, which is written into the report;
· Currently, the more durable on the market is metal core electric floor heating , graphene carbon fiber and so on are said to be attenuated, so don’t buy it;
· Don't worry too much about radiation. does have slight radiation, but will not cause harm to the human body. Otherwise, this category will be banned in Europe;
· Decision to install electric floor heating in generally requires capacity increase. You must tell the plumber in advance .

Electric floor heating also has an advantage that water and floor heating cannot compare. It can realize the independent switch control of in each room through the panel, and switch at any time. power consumption is controllable;
water and floor heating can also be realized now, but the water heating starts slowly, and it is also used with domestic water. cannot be turned off at will unless you travel far away.
Water floor heating requires a heat source, electric heating should not be
Keywords: wall-mounted boiler / Condensed wall-mounted boiler
The biggest difference between plumbing and electric heating is that plumbing requires ideas to heat, but electric heating itself does not require a heat source, which directly creates the purchase and installation cost of electric heating is simpler than plumbing.
The heat source for water heating can be directly connected to the municipal heating system or self-heating, and boil water through traditional boilers, buy gas wall-mounted boilers or condensate wall-mounted boilers.
In recent years, condensed wall-mounted boiler is being promoted everywhere because of "low water pressure control and more energy-saving", but from the perspective of saving money, small apartments under 80 square meters are not suitable for .
At first glance, a condensed wall-mounted furnace is 3,000 more expensive than an ordinary wall-mounted furnace, but it often has a maintenance fee of 1,000 yuan per year at a time. Does anyone tell you?
Take the common 24KW as an example. Ordinary ones can only be done about 5,000, but the imported ones are often priced at around 10,000; it takes 8 years and 4 repairs are 4,000 yuan, which is 3 times more expensive than ordinary wall-mounted furnaces;
, including the rising electricity and gas fees, it is really unnecessary to buy a "condensing wall-mounted furnace" by saving this reason in the later stage.

wall-mounted boiler choose . If you are in a hurry to buy, please refer to the following number:
General heating area is 50㎡, 18KW;
Heating area is 60~120㎡, 24KW;
≥120㎡, use 28KW~35KW;
villa or larger apartment , like European and American countries, consider a higher power condensing wall-mounted furnace or directly use air pump to keep heating . It is said that electricity and gas fees are also quite cost-effective.
wall-mounted boiler brand domestic products can be viewed on Little Squirrel , Wanhe, Wanjiale , Chuanger , Weixing , Milan Spring, etc.; joint ventures can be viewed on Viennang (Vaillant), Bosch (Bosch ); Italian Ariston (ariston), Ima (immergas), Linne , etc.
wet laying method is more cost-effective, and it is still the mainstream
According to different laying methods, the backfill layer of plumbing and electric heating is called "wet floor heating", and if it is not added, it is " dry floor heating ";
wet laying facilities are more complicated. However, the cost-effectiveness of . This kind of laying method used in 80% of the north will occupy a 10cm layer height; the
process is as shown in the figure below
from the blank delivery layer, in turn, the leveling layer (or traditionally built with wooden keel 2cm), white crystal board + aluminum foil insulation layer, hanging net fixing (some have, some do not), snap fixing water pipes, cement or bean mortar pouring leveling layer, and decorative layer.
Picture: Schematic diagram of network/wet laying
dry floor heating has no backfill layer. The fixed one is extruded board with relatively high cost and an aluminum foil insulation layer , which will save 2~3cm of layer height, but the cost is high, and ordinary people don’t use it much at home.
dry floor heating is also known as the "prefabricated board laying method" in Japan. It is simple to operate

The comfort of the two is similar
"Water will be more comfortable than electric floor heating", which is very rumored. If you do wet floor heating, the water heating will get very slow. It takes half a day to 1 day according to the area and wattage, and the electric heating reaches the set temperature in a few hours.
After 5 hours, the electric heating must be more comfortable than the floor heating; but after 1 day, the body feel is no different under the same set temperature.
It's like going to Lhasa from Beijing. After getting off the train and flying, the perception of hypoxia is different.
Train: I don’t feel much, plane: Give me 10 cans of oxygen hhhhh
budget and suitable for family
2 comprehensive comparison, water floor heating is suitable for central heating, which is central heating to improve floor heating is the most cost-effective; , which has been in the house for a long time, you can also consider plumbing and heating for self-heating. If you don’t turn it off, it’s not a waste;
electric floor heating heats up very quickly, suitable for office workers from from 9 to 5; if has a step price subsidy policy for in various places, it is also very cost-effective to use electric floor heating for small apartments. Houses above 60㎡ can easily exceed the step price of electricity, which is a little disadvantage.
If you talk about the budget, electric floor heating will be more invested in the early stage, and there is almost no maintenance required in the later stage. If is leaked, it can only be removed and replaced; water floor heating will be relatively less invested in the early stage, but it will be used for 2 to 3 years, and there will be maintenance fees. We have already learned a lot about the information related to electric floor heating in the comparison. Below we will dig deep into the purchase and construction pits of the ground heating in the water.
Six major pit points, we have the formula of water floor heating
Water floor heating = heat source + control + pipeline + insulation layer
We have seen the formula before, as shown in the figure below, this is a complete water floor heating diagram, and the main and auxiliary materials involved in different links are clear at a glance.

is messy, right? After you have finished installing your home, follow me to search for treasure:
central heating is very simple. Open your home cabinet or under the entrance door There is a box inside, which contains two major items of floor heating control, valve ( ball valve ), water collector ;
Home heating goes under the kitchen cabinet or on the balcony to find it. It’s ugly like a nest, is basically hiding ;
There is also a switch panel scattered in each room, you can tell at a glance.
heat source is simpler. Self-heating is basically love and hate wall-mounted boiler . It is inseparable from making noise every day. This is said in comparison with the party.
Pipeline and insulation layer You can't see it, is under the floor or tiles , the wet shop is very detailed, review this picture
, afraid of water leakage, choose an integrated forged water collector
Keywords: water collector + panel = control system
Water floor heating is perfect and does not leak water, no one dares to say this, but water leakage is traceable, and most of them are at the connection of the pipeline.
The most water floor heating connection points are water collector . The water collector is divided into groups, supplying water at the top and returning water at the bottom, one column is one circuit, and the pricing is also based on one circuit as a group, usually ranging from 260 to 320/per circuit.
According to the national standard, one circuit must control heating of 15~17㎡, and the experience of using the pipe is converted to about 70~80m; if it is a traditional small apartment room of , one circuit is enough for heating of one room.
How to calculate how many loops your home needs? The actual heating area is ÷ 15 or 17, and then the unit price per circuit (for example, 260 yuan/per circuit) is the total cost of the water collector.
is very obvious. The following is the heating of 4X17㎡ = 68㎡. The cost of
is 4x260 (estimated non-standard) = 1040 yuan.

Note! It is best to install two water collectors on the upper and lower floors of duplexes, respectively, , otherwise the second floor may not be warm.
It can be said that water collector is the core component of water floor heating . It controls the water flow and directly determines the temperature of the room. There is a standard flow calculation method for imported ones, but it is very expensive.
requires relatively frequent operations to control the water flow. is a consumable product, generally has a 2-year warranty, and it is fine for a good brand to use it for 8 to 9 years.
is afraid of water leakage . At the same time, if you can control the flow, just choose an integrated forging water collector . The biggest difference between it and traditional water collectors is that the interface of the pipeline is integrated, and there is no connection port that needs to be manually tightened, so water leakage will be avoided.
The materials of the water collector are divided into brass , copper alloy , stainless steel, PPR, etc. The mainstream brands of are all integrated forged multi- made of brass and copper alloy materials, which will be better in terms of corrosion resistance, sealing and product life.
The main water collector brands in the floor heating market are: Kalefi, Gacomini, Danvers, Owentop, Emmeti, Konafer, Manrede, etc.

Thermostat generally uses with water collectors. Choose a few rooms. Therefore, water collector manufacturers generally have their own brand of thermostats, and the brand is the same as above.

Keywords: Supervisor + Sub-pipe = Pipe
Pipe are all very mature industries, claiming to have 50 years of quality as long as does not buy miscellaneous brands and construct correctly, there will be no big problems with normal use.
Main is a section of pipeline from a wall-mounted boiler to the water collector, or a section of pipeline from the source of central heating to the water collector. It is thicker than the sub-pipe and has materials such as PPR, PPR aluminum-plastic pipe , steady-state pipe, etc. The more durable is PPR aluminum-plastic pipe .
Domestic big brands generally range from 90 to 120 yuan per meter.

Now most floor heating pipes (auxiliary pipes) uses cm diameter PRET three-layer or five-layer oxygen-blocking tube , Weixing and Taurus are mainly recommended, with a high cost performance, with a price range of between 120 and 140 yuan/㎡;
Better ones will use PE-Xa/b/c series. The most widely used PE-Xa series in China is the PE-Xa series. The price is moderate, and it is difficult to produce PE-Xb and Xc series. It is generally imported. Poly, a subsidiary of Foshu, can make it, but it is expensive;

used to have Pb tube , but it was gradually eliminated because it was too easy to scratch. Pay attention to ! Some guerrillas are miscellaneous brands with very low quotations. They use this kind of pipe. It would be strange if they don’t leak. Avoid pits and avoid pits;
suggests that the pipe materials should be used at home or to open the packaging, and to check whether it is the model in the contract when accepting the form. The outer layer of the secondary pipe generally has a model similar to the series . The following figure is as follows

European standard clearly stipulates that the tube must have an oxygen barrier layer, otherwise it will not be qualified. There are no clear regulations in China, but because there are too many impurities in the water, it is easy to corrode the pipeline. It is recommended that you choose an oxygen barrier tube.
actually adds an oxygen barrier coating to the inner and outer walls of the pipeline. Three thin layers and five thick layers. I think there is not much difference, just add it. When distinguishing , you can touch it with your hands. If added, it will be more delicate and reflective. If not added, it will feel a rough plastic feeling and impurities.

Worry about the heat transfer downstairs, how can we not leave outsiders' fields? It depends on the selection and construction details of the insulation layer.
· The laying density of the pipeline is . is naturally the denser the , the better , but it cannot be too dense to affect the construction of the backfill layer and heat transfer. is generally spaced 20cm, and use point snaps to turn places;
Note: This picture is a diagram of the exhibition hall. There is no fixed snap, and there must be a snap
· Reflection film must use double-sided aluminum foil to be beneficial to reverse heat
TIPS: Common reflective films include kraft paper, non-woven fabric, aluminum foil single-sided and double-sided. The double-sided aluminum foil will be thicker, look behind it.
pictures Zhufaner self-photo/ The front and back of the reflective film
insulation board is about 2cm thick, and is directly spread on the ground leveling layer to prevent heat from falling downstairs. choose the white crystal panel color with the best light transmission, which is environmentally friendly and practical;
Avoiding the pit and some brands or roadside stalls will use yellow or blue extruded boards. This is not environmentally friendly and will increase the release of formaldehyde ;
cannot be distinguished. uses a torch light to take it behind the insulation board. It mainly depends on whether there are many impurities. Accepting at home is the same method. If it is not possible, let the manufacturer take it back and set it up. Horses are re-modified;
reminds me, auxiliary materials have a brand called Green Yu , the brand and materials are good, but this brand is too popular, and some people are imitating it. I'm sure the logo~
and html l2 Two details that are easy to ignore:
. The insulation board and reflective film are all sized. . Be sure to paste the board and the film between the board and the film with aluminum foil tape. If you do not paste the unqualified
picture Zhufaner self-photo:
. If there is a gap between the insulation board and the corner, you must fill 3cm with the edges and corners insulation material , which must be done!
If it is wet floor heating , it is best to backfill the layer of bean stone (small pebbles) concrete or mortar backfill , so that it is easier to retain heat.
Never use spike stones casually, as they may easily scratch the secondary tube.

Remember to prepare a small wooden board or bucket in advance to facilitate stirring. Reject stirring directly on the water pipe, which may easily damage the pipe.
Backfill price varies from place to place. The general quotation for northbound is 50~70 yuan/㎡ . Where is your family? You can add it in the comment section, this money is also a lot.
Contract granules: more details
Floor heating industry is very complicated, and the brands are more complicated, mainly divided into imports, joint ventures and domestic brands.
imported, such as Ruihao, Vieng, etc.; joint ventures such as Rifeng , Vaillant, Bosch; domestic products such as Little Squirrel, Wanhe, Wanjiale, Chuanger, Weixing, Milan Spring (only serving Beijing and Tianjin), etc.;
Because floor heating is a very important installation job, most brands will choose large and powerful suppliers to cooperate to lay the market.
Instead of looking at the brand, it is better to look at the local dealer . The reliability of the dealer determines the final effect of the installation at home.
If someone forces it to be imported, please provide the corresponding tariff certificate.
Pictures are from the Internet
Whether you are finally here for "import" or you are interested in a brand of xx technology, is not as good as black paper and white words, and they are all written into the contract. The granularity of the contract must be detailed in terms of materials, models, sizes, pricing methods, total prices and corresponding services enjoyed.

· Note here that brands generally do not include backfilling , even if they backfilling, they are searched from third parties; the network is to prevent cracking, and each brand has different opinions and may not necessarily have them.
calculates money: The most cost-effective pricing is
mainstream pricing method is to first measure the heating area, design the heating plan based on the heating area, and then the final quotation is given after the renderings are drawn.
Picture Source from the Internet
The quotation for each ㎡ of auxiliary pipes includes all auxiliary materials.
Total price of floor heating = unit price of sub-pipe/㎡ x measured area + water collector x number of channels + main supervisor price/m x Total number of meters + wall-mounted boiler + valve + actual measured area x backfill unit price Yuan/㎡
Picture Network
Take an example of One bedroom, one living room and one bathroom, for your reference!
centralized heating and close to the heating source, the round-trip supervisor needs 4m in total;

10㎡ of cabinets and cloakroom custom cabinets are taken up, and the remaining 35㎡ is 35㎡, and the water collector is 35÷17≈2 channels;
sub-pipe is calculated at 100 yuan/㎡.
00x35 (price of auxiliary materials) + 2x260 (volume water collection price) + 4x120 (price of supervisor) + 480 (valve) + 0 (no wall-mounted furnace) + 35x60 (backfilling) =7080 yuan
This price is acceptable. If I have a wall-mounted furnace, I will directly consider changing the battery heating.
suppression and acceptance tip
After understanding these, you can basically go directly to the brand party to buy and buy, and then attach an acceptance TIPS for installation and laying at the end, so you won’t suffer any losses!
. backfilling period, pay attention to the pressure gauge of water divider ;
. Pressure test , the initial pressure value is 0.4~0.8Mpa, and the ground leveling can be performed after 2~3 days; the pressure value of is generally stable in the range of 02~04Mpa, which belongs to the normal , and the decoration can continue.
Fine-decorated floor heating acceptance can be carried out based on this data. If the pressure value is below 0.1, it may be water leakage or the pipeline is damaged.

. water distributor and valve should be installed in the cabinet as much as possible, and close to the heat source to save the supervisor and not affect the beauty;
. pipe laying spacing should be between 17~20cm, too close or too far affects backfilling;
. The connection between the reflective film and the reflective film must be pasted and fixed to reduce heat loss;
. The insulation strips of are pasted by the wall, and it is best to have 3cm at the junction at the junction. The right overlap ;
. The nail is fixed, and the straight tube of is 40cm, and the turning point is 10-20cm, one ;
. The area is greater than 30㎡/the length of the aisle is 6m/the threshold is passed, and at the junction of complex areas, must make expansion joint ;
