Why does water flow faster in underfloor heating and the higher temperature

Water floor heating refers to heating water to a certain temperature, transporting water to the water pipe cooling network under the floor, and heating through the floor.

A heating method that realizes heating.

Water supply temperature: 50 60, the maximum temperature should not exceed 60. Water supply pressure: , the maximum should not be greater than MPa.

The temperature difference between the supply and return water: should not be greater than 10.

The flow rate of hot water in the heating pipe v: should be controlled at .

Thickness of geothermal radiant heating structure: 50 80mm (excluding screeds.

and the thickness of the floor decorative layer), of which the insulation layer is 30 50 mm, and the filling layer is 25-30 mm. Structural weight of geothermal radiant heating layer: 70 120kg m2.

Ground temperature control: The ground temperature of personnel staying for a long time should be controlled at 24 26, the ground temperature of personnel staying for a long and short term should be controlled at 28 30, and the ground temperature of areas without personnel staying should be controlled at 35 40.

The method of water underfloor heating is through the circulation of hot water.

to heat the floor, conduct heat, and make the room warmer. Heat is brought through the water cycle, the faster the circulation, the higher the temperature rises, in fact, this is a typical heat transfer process, the increase in flow rate is bound to increase the circulating water, which directly leads to the increase of heat, and more heat will be transferred to the floor and to the room, so that the faster the flow rate, the higher the temperature.

Faster is not always better, and needs to be kept within a reasonable range.

A high temperature difference can be maintained, so that the heat conduction efficiency is high.

1. The flow rate of floor heating is not as fast as possible, and the normal flow rate of floor heating is generally to, and the minimum can not be lower. If the flow rate is too fast, the workload of the floor heating equipment will increase, the operating cost will be large, and it will not save energy; Slow flow rates will lead to longer water circulation, resulting in hot water in the first half and water cooling in the second half.

2. If the flow rate of the floor heating is too fast, you only need to reduce the water pressure for heating. If it is not cleaned for a long time, the floor heating filter will adhere to a lot of impurities and scale, resulting in a very slow flow rate of floor heating; If the floor heating water does not reach 45 degrees Celsius, it will also cause the floor heating flow rate to be slow, you can try to open the return valve to discharge water, and if it is not possible, contact the demolition floor heating company.

Summary. Kiss, <>

We're glad to answer your questions! The temperature difference between the inlet and outlet water of floor heating is not as small as possible, and the temperature of the backwater and the inlet water is not the same, and there is a certain temperature difference between the two, but the temperature difference range can not be too large, generally not more than about 10 degrees. If the inlet temperature is set at 50 degrees, the return water temperature should be set at 40.

If the inlet water temperature is 60 degrees, the return water temperature should reach 50 degrees. Usually a difference between 5-10 degrees is more suitable. There is a temperature difference, but it is not absolute, and the higher the inlet temperature, the greater the temperature difference.

If the temperature difference is relatively small, it will affect the heating effect. Hope mine can help you! <>

We're glad to answer your questions! The temperature difference between the inlet and outlet water of floor heating is not the older and smaller, the better, the temperature of the backwater and the inlet water is not the same, there is a certain temperature difference between the two potatoes, but the temperature difference range can not be too large, generally not more than about 10 degrees. If the inlet temperature is set at 50 degrees, the return water temperature should be set at 40.

If the inlet water temperature is 60 degrees, the return water temperature should reach 50 degrees. Usually a difference between 5-10 degrees is more suitable. There is a temperature difference, but it is not absolute, and the higher the inlet temperature, the larger the temperature difference.

If the temperature difference is relatively small, it will affect the heating effect. Hope mine can help you! <>

The temperature difference in my house is 3 degrees, is it normal.

Pro: Normal.

The temperature in the room is not high, I don't know why.

If the temperature at home is low, it is generally because the ventilation situation at home is too good, resulting in a faster drop in the temperature at home, and it may be that the heating equipment cannot achieve the desired functional effect.

The floor heating flow rate is generally reached, and the minimum cannot be lower. The flow rate should not be too fast or too slow, if the flow rate is too slow it will cause the water to cycle once it takes too long to be hotThe water will not be hot in the second half of the circulation, and the first half will be hot and the second half will be cold, and if the flow rate is too fast, it will speed up the workload of the underfloor heating equipment, which is not energy-saving. <>

Causes and solutions of slow floor heating flow rate 1, if the floor heating pipe is not cleaned for a long time, there will be a lot of impurities and scale attached to it, and the floor heating filter page may cause blockage. SolutionMethod: Remove the floor heating filter for cleaning, and at the same time you can ask the floor heating cleaning personnel to clean it, if you don't want to invite someone, you can clean it by hand.

2. The pressure of floor heating water is not enough, which will lead to a relatively slow flow rate of floor heating water, and the uneven pressure distribution of floor heating pipes is generally caused by the different lengths of floor heating pipes, mainly because of construction reasons. Solution: This situation rarely occurs in construction now, because the length of the floor heating will generally be set uniformly before the installation of floor heating, ifThis problem occurs because the length of the floor heating pipe is unreasonable, and it may be necessary to reinstall the floor heating, so in order to avoid this situation, you need to find a professional floor heating installer when installing the floor heating.

3. The temperature of the floor heating water stipulated by the state must be above 45 degrees, if the heating floor heating water does not reach 45 degrees, it may also lead to slow water flow. Solution: Let's open the outlet of the return valve firstAfter the water has been released, it is found that the hot water still does not reach 45 degrees, it must be the reason for the floor heating equipment, then we have to find a floor heating company or heating party to solve, and the floor heating that is generally bought has a long warranty time.

The floor heating flow rate is generally reached, and the minimum cannot be lower.

Geothermal heating system is the most comfortable way to heat, the indoor surface temperature is uniform, the room temperature gradually decreases with the increase of height from bottom to top, and this temperature curve is just in line with the physiological needs of people.

We first open the outlet of the return valve, and find that the hot water still does not reach 45 degrees after releasing the water, which must be the reason for the floor heating equipment, then we have to find a floor heating company or heating party to solve, and the floor heating that we generally buy has a long warranty time.

Remove the floor heating filter for cleaning, and at the same time, you can ask the floor heating cleaning personnel to clean it, if you don't want to hire someone, you can clean it by hand.

If the flow rate is too fast, it will speed up the workload of the underfloor heating equipment, which is not energy efficient.

The hot water will not be hot in the second half of the circulation, and the first half will be hot and the second half will be cold, and if the flow rate is too fast, it will speed up the workload of the floor heating equipment, which is not energy-saving.

The temperature difference between the incoming and returning water of the floor heating is large, and the heat meter goes fast.

Kiss! Hello, happy to answer your <>

The reason for the large temperature difference between the heat meter and the rapid heat meter is as follows: because of the poor circulation of the heating system, the geothermal heating system is referred to as floor heating, which originated from the soil kang in northern China, and was absorbed and improved by Japan and South Korea, and we now call it ground heating. In Japan, South Korea geothermal heating history has been more than 40 years, in Japan, in 1965 produced an electric floor heating system, in the 70s by the Japanese Tokyo Gas Company developed a warm water geothermal heating system, this heating method has been widely welcomed by the Xu, because of its heating method of good heat conduction, high thermal efficiency, more in line with the needs of the human body for temperature cascade distribution.

The feet are warm and the whole body is warm, because the heart is the farthest away from the feet and hands, and the first part of our body to feel cold in winter. Hope mine can help you <>

Do you have any other questions?

The lack of heat in underfloor heating is related to many physical factors such as flow, flow rate, pressure, etc., because the method and precision of installing pipes and the geothermal energy of the earth will affect the entire geothermal system. Some geothermal users are likely to encounter a situation where the inlet pipe of the geothermal heat is hot and the return pipe is not.

Experts say that geothermal heat is a circulation problem, and you can check whether the total running air is blocked, or check whether the main return valve is open.

Normally, the geothermal inlet pipe is hotter than the return pipe, but if the return pipe has almost no temperature, it is possible that the following conditions are:

The filter is clogged, resulting in insufficient water supply.

2.The return valve is closed or not fully opened. The return pipe valve can be opened wide. From the valve, it is open in a straight line with the pipe, and closed in a cross shape.

3.There is air in the tube. You can open the air release valve on the water separator to release the air.

4.There is too much silt in the geothermal pipes, which causes the water to flow slowly. If this happens, the floor should be cleaned.

Many geothermal users are not even clear about the inlet and return pipes, experts tell you a simple test method, try the temperature of two rows of pipes, the hot is the inlet pipe, and the low water temperature is the return pipe.

The most important thing is related to the water temperature, followed by the flow, flow rate, and pressure. Hermani water separator with flow meter for smarter temperature regulation.

Underfloor heating can increase the temperature by regulating the water flow rate for the following reasons:

Underfloor heating is done by circulating hot water.

to heat the floor, conduct heat, and make the room warmer. Heat is brought through the water cycle, the faster the circulation, the higher the temperature rises, in fact, this is a typical heat transfer process, the increase in flow rate is bound to increase the circulating water, which directly leads to the increase of heat, and more heat will be transferred to the floor and to the room, so that the faster the flow rate, the higher the temperature.

The suitable water flow rate for underfloor heating is:

1. Internal heat in the floor heating coil.

The flow rate of the medium should be less than .

2. The spacing of floor heating coil laying should be based on the heat dissipation of the ground, the interior design temperature, the average water temperature and the heat transfer heat resistance.

Determined by calculation. The spacing of pipelines should not exceed 300mm. (The spacing of the pipes should be 100-300mm, and the distance between the heating pipes and the inner surface of the outer wall should be 200mm).

Underfloor heating regulates the water flow rate to increase the temperature needs attention:

Faster is not always better, and needs to be kept within a reasonable range.
