Is the calculation method of gas boiler output power in the United States the same as that in China?

The calculation method should be the same, are based on the law of conservation of energy and the law of conservation of mass, the explanation given by the manufacturer is unreasonable, the possibility of error in the identification row is very small, the difference between large-capacity boilers is not large, and the small-capacity boiler is not, in any case, the actual output of the equipment can not be less than 5% of the contract output, strictly speaking, it should be 2%, 10% is too much.

Less is smaller, of course, it affects the heating, this algorithm is the same, and it is also expressed in kw in China.

The gas boiler water heater is measured in MW, and the steam furnace is generally used in T h

The company explained that the calculation method in the United States is different from that in China, and that the difference in output power will affect the heating effect.

1. Equipment manufacturers love to fool people, in fact, the thermal power system basically adopts the International System of Units. What is the International System of Units? That is, the heat measurement standard of each country is the same, so it is called the International System of Units.

2. The difference will not affect your heating, the heat emitted by the boiler is related to the consumption of gas, and the working range of each boiler is impossible to touch the same, and we can't feel it when we use it. A difference of 10% is fine. If the manufacturer's debugging level is high, then your wall-hung boiler can work at an output state of 61kw (but this needs to be tested by special instruments, and it is estimated that they don't.)

I have it here, the cost of testing is very high, and a test report is at least 3,000 yuan).

Again, it is generally measured in MW.

The power of a gas boiler mainly refers to its thermal power or output power, which is usually expressed in kilowatts (kW).

There are several factors that need to be taken into account to calculate the power of a gas boiler:

1.The size of the area that needs to be heated: In general, the larger the area, the more thermal power is required.

2.The thermal insulation performance of the room to be heated, including the material and thickness of the insulation structure such as walls, roofs and floors, the quality and thickness of the insulation material, etc.

3.Geographical location, climatic factors: The power required will vary depending on the region and climatic conditions.

4.Factors such as the number of people who need to be heated, the intensity of activities, and the heat load of other uses (e.g. household water), etc.

Generally speaking, the power of a gas boiler can be calculated according to the following formula:

The power of the gas boiler (kw) = heating area (square meters) x the required heating power (w square meters).

The required thermal power can be adjusted according to factors such as regional climate, building insulation performance, etc., and is generally 80 120W square meters. For example, if the area to be heated is 100 square meters, the required heat power is 100 square meters x 100w square meters = 10,000 watts, i.e. 10 kw. Therefore, the family needed to purchase a 10kw gas boiler to meet its heating needs.

The power of a gas boiler is generally measured in kilowatts (kW) and is calculated as follows:

Determine the size of the room that needs to be heated. In general, 100 W of power is required per square meter of heating capacity, i.e. 1 kW of power is required for 10 square meters.

Calculate the required gas boiler power. Multiply the area of the room that needs to be heated by the power required per square meter (e.g. 100W) to get the required gas boiler power (kW).

Consider additional factors. In addition to the size of the room, additional factors such as how well the building is insulated, the temperature requirements in the house, etc., all affect the required boiler power.

It should be noted that the power of the gas boiler should not be too small or too large, too small will lead to insufficient heating, too large will lead to energy waste and equipment loss, so when calculating the power of the gas boiler, the required power should be determined as accurately as possible, and adjusted according to the actual situation.

There are many factors that need to be considered for the power of the gas boiler, such as the type of Heyin boiler, the type of gas, the thermal efficiency, and so on. In general, the power of a gas boiler can be calculated by the following formula:

Power (kw) = Total heat demand (kw) Thermal efficiency.

Total heat requirements include heat requirements for heating and hot water, and can generally be estimated by interior design temperature, floor area, and insulation rating. Thermal efficiency refers to the efficiency of a gas boiler in converting gas energy into heat energy, which generally depends on the type and design of the boiler.

It should be noted that the power of the gas boiler should be slightly greater than the total demand for heat and hot water to ensure sufficient heating and hot water**. At the same time, it is also necessary to consider the quality of gas, and the calorific value of different gas types is different, so the power of the gas boiler needs to be adjusted accordingly.

Gas Boiler Efficiency Efficient Use of Heat All the heat that can be released from the fuel slag*100.

Gas boilers include gas boiling water jujube boilers, gas hot water boilers, gas steam boilers, etc., among which gas hot water boilers are also called gas heating boilers and gas bath boilers, gas boilers as the name suggests refers to the boiler whose fuel is fired by the state, and the gas boiler is the most economical compared with the oil-fired boiler and electric boiler, so most people choose the gas boiler as the boiler equipment for steam, heating and bathing.

Gas boilers include gas boiling water boilers, gas hot water boilers, gas steam boilers, etc., among which gas hot water boilers are also called gas heating boilers and gas bath boilers, gas boilers as the name suggests wide lack of eyes refers to the boiler with gas fuel, gas boilers and oil-fired boilers, electric boilers are the most experienced compared to the car, so most people have chosen gas boilers as boiler equipment for steam, heating and bathing.

The calculation formula of thermal efficiency of gas boiler is: boiler thermal efficiency = 100% - (a + b + c + d + e) 1, a = exhaust gas heat loss. The heat loss increases by about 13% for every 13 or so increase in exhaust gas temperature, that is, (exhaust gas temperature - room temperature) the heat loss of incomplete combustion of gas.

3. C = mechanical incomplete combustion heat loss. 4. D = heat dissipation loss. 5. E = physical heat loss of ash.
