Which is better, gas water heater or electric water heater? How to choose?

What is the difference between a gas water heater and an electric water heater? Which one is better? A water heater with a complete configuration is not only more comfortable to use, but also more secure.

Generally, we look at whether the water heater is equipped with the following devices: magnetic core filtration device at the water inlet, bypass pipeline design, and intelligent sensor system.

If you have a good budget, it's best to buy a gas water heater. Gas water heaters can add many functions, such as constant temperature and pressure, zero cold water. This additional feature can make gas water heaters better and better, while domestic water heaters have very few options.

Gas water heaters ignite vapor when boiling water. The heating rate is fast, and there will be a constant stream of boiling water when bathing. However, when you have just taken a bath with boiling water, you should put some cold water.

The household water heater is hot as soon as it is turned on, but the electricity consumption is not enough to boil the hot water quickly, so it can only be boiled first and then stored. The flow of hot water is limited, so it is easy to have no hot water halfway through washing, and the more you wash, the cooler it gets.

Gas water heaters do not need daily maintenance, but it should be noted that some places refer to natural gas instead of natural gas. Natural gas can easily produce harmful carbon monoxide due to uneven ignition, so electric water heaters should be installed in natural ventilation. The advantage of household water heaters is that they can adapt to any weather changes, do not produce organic waste gas during use, and are more hygienic.

The main disadvantage of domestic water heaters is that they occupy a large interior space and are very prone to fouling. Because the water in the light must be insulated, the electromagnetic energy consumption is very large; It is inconvenient for many people to continue bathing, and those in the back need to wait for the water in the gall to be heated again before they can use it. Although most domestic water heaters are equipped with leakage protectors, safety accidents still occur frequently.

The household water heater is a volumetric type, after heating up a box, the temperature of the water just used is high, and the heated water must be pushed out with cold water, and at the same time some cold water is supplemented. In the bouncing session, the temperature of the water is relatively high at the beginning, and it gradually decreases with the application, and the proportion of hot and cold water must be constantly adjusted during use. For domestic water heaters, the temperature of the water is stable, the assembly is convenient, and the water flow is fixed.

However, the heating time is long, and it cannot be applied immediately; It is not possible to continuously use the flow of water that exceeds the rated current. If you bathe a lot in your house, you'll have to wait for the water to boil halfway; The storage tank is prone to the deposition of fine sand and bacteria, which has health implications. Secondly, due to the deposition of precipitation, the efficiency of the electric heating rod will be affected, resulting in longer heating time and higher power consumption.

If you have a good budget, it is best to buy a gas water heater. Gas water heaters can be used in many additional ways, such as the constant temperature and pressure, zero cold water, as I just mentioned. This additional feature can make gas water heaters better and better, while domestic water heaters have very few options.

The electric water heater is better, and now it is generally an electric water heater, which is very convenient, and clean and hygienic.

The electric water heater is better. If you want to save money on gas bills, you can use electricity.

Both types of water heaters have their own advantages. Both gas and electric water heaters are capable of providing stable heat supply. But in terms of safety, electric water heaters will be higher.

Nowadays, while the temperature is getting lower and lower, there is nothing more pleasant to do every day than to take a comfortable hot bath. Water heaters are indispensable in life, especially in the cold winter, and from the current market share, the most used by people is nothing more than gas water heaters or electric water heaters. SoWhich is better, gas water heater or electric water heater?

The common gas water heater in life is generally 11-24 liters, which refers to the amount of hot water produced by the water heater per minute. However, the water temperature will be lower in winter, so the actual result will be slightly smaller. The electric water heaters we often talk about are generally water storage types, with a capacity of 30-100 liters.

From the point of view of the choice of hot water volume, if it is a gas water heater, as long as multiple faucets are not used at the same time, the general house type of one kitchen and one bathroom is 12-13L. If you install an electric water heater, you should choose according to the water consumption of 20-30L per person, that is to say, if it is a family of three, it is generally recommended to choose a water storage capacity of 60-90L for the electric water heater.

In terms of heating speed

The heating speed should be the biggest difference between gas water heaters and electric water heaters, and gas water heaters are basically ready to use; In the case of electric water heaters, it is usually necessary to turn on the electricity and increase the heat resistance of the bridge first, and it takes a while to wait.

From the point of view of the stability of the hot water temperature

At present, many gas water heaters are mainly thermostatic, will not be hot and cold when bathing water, slightly low-end gas water heaters may have some temperature fluctuations, in order to use hot water more comfortably, it is recommended that gas water heaters choose with constant temperature function. And because the electric water heater is used to store water, if the inlet valve is opened, after the hot water in the tank is used to a certain extent, the hot water will be reduced, and the temperature will naturally be reduced.

From the aspect of energy consumption, we can look at the spring

Due to the differences in electricity and gas bills in each place, as well as the different usage rates of each household, it is difficult to say who is more economical than whom. However, if people's living conditions are getting better and better, and fewer and fewer people really care about this difference in energy consumption, it is recommended that everyone choose according to the electricity and gas in their own area or according to their actual use.

In terms of occupied area

In this era when every inch of land is at a premium, whether it is decoration or buying electrical appliances, you must consider the occupied area. Gas water heaters are not large in size, and they are generally installed in the kitchen, taking up a small area. The electric water heater is relatively large in size because it has a water storage tank, and it needs enough space when installing.

From the security aspect

Some people may have concerns about gas water heaters and electric water heaters after watching water heater poisoning and electrocution a few years ago, but in fact, which accidents on the news are basically caused by improper installation and use or the use of counterfeit inferior products. In fact, as long as it is a regular brand, regular installation, and normal use, it is very safe whether you use a gas water heater or an electric water heater.

What's the most comfortable thing about coming home from work? That must be "take a comfortable hot bath!" "Here's the point, you have to choose a good water heater for a hot bath, right?

On the market, there are two main categories of water heaters: gas water heaters and electric water heaters, but which of the two is more suitable and easier to use?

Based on the specific use experience, I recommend the electric water heater.

1.Safety: Gas water heaters are prone to carbon monoxide, reducing indoor oxygen content, and need to be installed in a space with good ventilation conditions, while electric water heaters do not need to consider these safety issues.

2.Mature technology: At present, most of the electric water heaters are intelligently designed, and you only need to set the time and temperature in advance when using, and you can enjoy the convenience of instant heating.

3.Convenience: Compared with gas water heaters, electric water heaters have less installation restrictions, can be installed where there is electricity, and water temperature adjustment is also more convenient, without too many cumbersome operations.

Electric water heater

The water in the tank is heated by the electric heating rod of the electric inner tank, and the power consumption is relatively large, and the water needs to be heated at one time, but it is very convenient for some buildings without gas, and the installation is also very convenient.

Purchase tips:1Heating method: The heating method determines the speed of heating water, when buying an electric water heater, the budget is enough to clear Kangxi, pay attention to the water heater with double pipe heating as much as possible, the heating speed is fast, the bathing is more convenient, and the advantage of bathing in winter is great.

2.Machine liners: Most of the common electric water heater liners on the market are enamel liners, which are more corrosion-resistant, have a long service life, and are more cost-effective. And the follow-up maintenance is more convenient, the welding technology of the stainless steel liner is more troublesome, and it is generally not recommended to consider.

3.Safety: The machine needs to be powered on, so the safety performance also needs to be paid attention to.

Gas water heaters

Natural gas Gas is used to heat water instantly, and the product is small in size and heats up quickly, but it must rely on gas to be used and need to be installed outdoors.

Purchase tips:1Water temperature adjustment: choose the constant temperature control mode, which can ensure the stability of the water temperature, not affected by distance and water pressure, and the cost-effective can choose the constant temperature mode of water and air dual adjustment.

2.Capacity: 1-2 people 12-13L, 3-6 people 14-16L, if it belongs to a large house, friends with a sufficient budget, in order to ensure the use, it is recommended to consider a gas water heater with a capacity of more than 16L.

3.Safety: One of the most important purchase conditions of gas water heaters, everyone's concern about gas water heaters is that there is a certain danger of generating exhaust gas, which mainly depends on the smoke exhaust mode of the machine.

In a comprehensive comparison, these two products have advantages and disadvantages, so you can't draw a direct conclusion, and it is recommended to choose according to your actual needs, space size, and budget.

What is the difference between a gas water heater and an electric water heater? Which one is better?

Electric water heaters are quite different from natural gas water heaters. They all use different sources of electricity. Although they can produce the same rate of boiling water for everyone's application, the form in which they boil boiling water is completely different.

In our general understanding, domestic electric water heaters will be more powerful than natural gas water heaters. However, it is very likely that the real situation is not exactly what it seems. This shows that everyone's mastery of water heaters and natural gas water heaters needs to be further aggravated.

Household water heater is an electric water heater that is driven by electric power engineering for electric energy, in order to better ensure safety, it is generally equipped with a leakage protector, which can effectively prevent the external power hazard. This means that the power protection switch is related to the reliability of the entire water heater application. In the past, due to technical shortcomings, there were even some instances where the user was electrocuted in the bath.

In fact, if you touch a household appliance with water in your hand, it is easy to make yourself a power transmission line, and in conclusion, it is easy to cause accidents.

Natural gas water heater is an electric water heater that is ignited and heated by natural gas or liquefied gas, and the application of natural gas water heater should pay attention to the problem of gas leakage, there are many examples, the user is poisoned and died in the bathroom due to gas leakage of natural gas water heater, mainly because of their weak awareness of prevention, and in winter the window door is closed, sometimes the gas leaks, but they are unaware, and finally cause accidental death. This shows that electric water heaters and natural gas water heaters are not absolutely safe. If you use an electric water heater in the summer, it is safer to use a natural gas water heater because the windows and doors can be opened and natural ventilation can be ensured.

But in winter, when the climate is drier, electric water heaters are likely to be very safe and can prevent everything from going out of the way.

The whole process of heating the electric water heater is generally invisible, as long as the safety of the leakage protector is ensured, we can ensure that it is not easy to leak to the greatest extent. In this way, it is impossible to cause ** accidents. In general, perhaps natural gas water heaters are likely to be safer and can prevent as many accidents as possible, because the safety accidents of natural gas water heaters can be prevented, and once the safety accidents of electric water heaters occur, it is not a joke, it is almost irreversible, and it is best or can choose natural gas water heaters.

I think there are many differences between the two, in terms of cost, gas water heaters are actually a little more expensive than electric water heaters, and I think electric water heaters will be more convenient; I think that if you can choose an electric water heater according to your own needs, it has a certain limit on the amount of water, and if there are many people in the family who want to take a bath, it is actually impossible to keep up, but if you want to take a bath in a gas water heater, you have to put cold water before taking a bath every time.

Gas water heaters and electric water heaters are actually about the same, except that one burns gas and the other uses electricity, and I personally think that gas water heaters are more energy-efficient than electric water heaters.

Gas water heaters are heated with gas, and electric water heaters are heated with electricity. If you want to use hot water as soon as you turn on the faucet, you have to choose a gas water heater.

The electric water heater is good, the electric water heater can adapt to any weather changes, does not produce exhaust gas when used, and is relatively hygienic.

1. Safety comparison.

Gas water heaters have the hidden danger of gas poisoning, and the problem of leakage of electric water heaters has also occurred. Therefore, strictly speaking, there is no absolute safety of water heaters, the main thing is that the installation and use must be standardized, so there is no big problem in terms of safety of the two.

2. Comparison of occupied space.

There is a water heater on the ceiling of the bathroom, how uncomfortable it looks. The electric water heater is a water storage type, and the larger the volume, the more water is stored, and the corresponding occupied volume will be. For the bathroom with a small area, there is no way to do it completely hidden, so you can only choose semi-hidden or surface-mounted.

In addition to being ugly, this also takes up space, making the space that is not spacious even more cramped.

The gas water heater is an instantaneous heating method, which is small and generally placed in the kitchen ventilation and does not take up much space. So in this regard, gas water heaters will be better than electric water heaters.

3. Comparison of costs.

The most intuitive energy consumption cost is to look at the data to speak, suppose to heat 100L of water, from 20 to 50 at room temperature, which involves a formula about heat, the heat of water = the specific heat of water * the quality of water * temperature difference, apply the formula, the 100L of water needs 1 kilocalorie * 100 liters * 30 = 3000 kilocalories.

According to the conversion of 1 kWh = 1 kWh = 860 kcal, the electricity used to heat 100L of water with an electric water heater with a thermal efficiency of 97% is 3000 kcal (860 kcal * 97%) kWh.

The gas heat production capacity is basically about 8500 kcal, assuming that a gas water heater with a thermal efficiency of 80% heating, needs 3000 kcal (8500 kcal * 80%) of gas, the gas ** is different from place to place, assuming that the unit price is 2 yuan m, the gas cost is 2 yuan m*yuan, this cost is obviously for the electric water heater.

Therefore, in terms of energy consumption, gas water heaters also have certain advantages, the reason why many families install gas water heaters is determined according to the cost of energy consumption, but the electric water heater has no noise at work, this aspect is its advantage, if the family house is large, it is also good to install an electric water heater with electric capacity, in short, it is necessary to buy according to the actual situation of the family.
