Electric water heater. Generally installed in the bathroom, the volume is larger, it will occupy the bathroom that is not large, and the water storage is limited, once it is used up, it needs to be re-boiled, like the family is more or the girl takes a bath for a long time, it is easy to wash to the back without hot water, but when the hot water is sufficient, the water flow can still be guaranteed. Electric water heaters are only affected by electricity consumption, and are the mainstream products in storage water heaters, and the biggest problem is that in addition to the limited amount of hot water, the power consumption is a bit too much.
Gas water heaters.
Generally installed in the kitchen or balcony, occupies a small area, is a kind of ready-to-use water heater, it can have a steady stream of hot water, and the disadvantage of the gas water heater is to put down the cold water in advance, if the gas stove is far away from the bathroom, it may have to be put cold water for a long time, and the water temperature of cold water hot water is not easy to control, but it is more convenient to master its regularity after a long time, and it is more suitable for more people. At present, most gas water heaters are strong exhaust type, and mainstream products have added a lot of protection measures to basically avoid carbon monoxide.
Threat. The heating efficiency of gas water heaters is also relatively high, which is more energy-efficient and stable than electric heating.
-
The key depends on whether the cost of connecting geothermal water is reasonable.
Whether the cost of use is low.
to be able to compare with gas water heaters.
Wishing you health and happiness.

Small apartment of 10-13 liters of three bedrooms and one living room with 16L liters, if the area does not have a natural gas water heater owners should also be installed in the natural gas water heater pipeline, and it does not affect the use of electric water heaters, if there is natural gas when the time comes, you can buy a gas water heater to install it, so the final analysis of the water heater is ultimately more than the electric water heater, if the cost of the end of the year to calculate the gas cost of bathing and gas stove for a year is about 100 yuan, and the electricity cost is about 600 yuan a year.
The biggest danger of gas is gas leakage and gas poisoning, as long as it is not installed in the bathroom according to the regulations, it will not be gas poisoned. As long as there is no **limit, there is no ** limit for air leakage, and there is no small fire at most. In terms of safety, I think gas water heaters win.
2.Convenient, ready-to-use, environmentally friendly and green. However, it is relatively high and must be installed outside the bathroom, so that the exhaust duct can be easily led to the outdoors, and it should be used frequently, if it is not used for a long time, it is easy to fail.
The electric water heater should be heated first, and it is necessary to wait for time, if the gas water heater is used, there will be hot water when it is used at any time, relatively speaking, the gas water heater is better, the electric water heater needs to adjust the water temperature, and the capacity is limited, if there are many people at home, the storage water heater is difficult to meet the needs of the family. But the storage water heater is cheap, if you are renting a house, it is ideal to use a storage water heater, because it is cheap.
Since the electric water heater is generally a volumetric water heater, it is necessary to store the hot water in advance, even if the water temperature is not used, it will drop and cause waste, while the gas machine is generally instantaneous, there will be no such problem, so the gas machine will save money when it is actually used; Let's say that the state has compulsory certification for this kind of products, so product safety is guaranteed. Which electric water heater does not have protection measures and means such as anti-electric wall three-pole disconnection leakage protection, and there is no need to worry about insufficient combustion and smoke exhaust. Storage water heaters cannot be compared to gas.
Instantaneous electric water heaters are definitely cheaper than air water heaters if the electricity cost is only six or seven cents, but there are requirements for the installation conditions, electricity meters, and meter lines.

The following is still an electric water heater that saves money, because our house is installed with electricity, and the electricity bill is not very expensive, which is about the same as daily consumption.

Relatively speaking, gas water heaters should save some, and the ** of natural gas is lower. Electric water heaters consume less electricity in summer, so they cost less. However, in winter, due to the low ambient temperature, the heating time is relatively long, and the power consumption is very large.
It depends on the user's geographical location. Advantages and disadvantages of gas water heaters and electric water heaters: 1. Advantages 1. Gas water heaters:
Ready-to-use, no waiting, and a small footprint saves space. In terms of safety, the gas water heater realizes the separation of heat production and heating, bathing in the bathroom, and installing it in the kitchen, avoiding the danger of electricity leakage generated during the bathing process. In terms of use cost, the first level of natural gas is relatively low, so the use of it is relatively low.
2. Electric water heater: storage electric water heater has high safety performance and clean energy. It can supply water through multiple channels.
It can be used for showers, baths, laundry, and vegetables. It is also relatively simple to install and easy to use. Instantaneous electric water heaters are small in size, do not take up space, easy to install, can be washed with water, have no time limit, and are relatively less power-saving than storage water heaters.
2. Disadvantage 1, gas water heater: first of all, it should not be installed in the bathroom or far away from the kitchen, because in principle, the gas water heater is not installed in the bathroom, if it is far away from the kitchen, the hot water pipeline is too long, and a lot of water resources will be consumed in vain. In addition, the inconvenience is that the user cannot adjust the temperature by himself during the bathing process, but must adjust the temperature before entering the bathroom, and the temperature will fluctuate from cold to hot, and occasionally there will be a problem of not igniting.
2. Electric water heater: storage type electric water heater is generally large in size, needs to be preheated before use, can not continuously use the amount of water beyond the rated capacity, the amount of hot water is limited by the capacity of the water heater, if there are many people, you have to wait for the middle of the bath. Especially in the north in winter, the heating time is long, the power consumption is very large, and the hot water can only be used by one person for bathing.
In addition, the unused hot water after washing the storage type electric water heater will slowly cool down, resulting in waste. The water temperature is high and easy to scale, so it is necessary to clean the scale stains regularly. The instantaneous electric water heater has a lot of power, and the specifications and thickness of the meter and power cord are high, and the water output is small, especially when the ambient temperature is very low in winter, the water temperature can not be guaranteed, and the comfort is poor.
-
Natural gas is more economical, because the cost of natural gas is relatively low, and the electric water heater is built more often, and the electricity bill is larger.
-
Natural gas is cheaper because it doesn't use electricity and consumes less energy.
-
Gas water heaters save more money.
That is the most cost-effective gas water heater, only need to pay some costs when installing, and there is not much capital consumption in the later stage. The cost of installing an electric water heater is the same as that of a gas water heater, but there is a large amount of electricity consumption in the later stage, so it is more cost-effective to choose a gas water heater.
Although the gas water heater is cost-effective, it also has disadvantages, and it is necessary to use a strong exhaust gas water heater, otherwise it is easy to develop carbon monoxide poisoning when used in the future. Secondly, its environmental protection is much inferior to that of electric water heaters. Moreover, the installation location of the gas water heater can only be the kitchen, not the bathroom.
Through the above introduction, it can be concluded that gas water heaters are more cost-effective, but they are more complicated to use, while electric water heaters are easy to install, easy to use, safer, and more cost-effective than gas water heaters.
Electric water heaters are divided into regenerative type and instantaneous type, and the regenerative type does not require water, but the disadvantage is that you need to make an appointment to boil water, and the water will get cooler and cooler the more you wash. Instantaneous hot water is available immediately, but with a lot of power. Natural gas water heaters and electric water heaters have their own advantages, and you can choose according to your own situation.
Water Heater:
A water heater is a device that turns the temperature of cold water into hot water in a certain period of time through various physical principles. According to different principles, it can be divided into electric water heaters, gas water heaters, solar water heaters, magnetic energy water heaters, air energy water heaters, heating water heaters, etc.
First of all, Wanhe gas water heater is better. Wanhe Group was established in August 1993 and is located in Shunde, the hinterland of the Pearl River Delta. Now it has one of the largest sterilizer production bases in Asia and a large-scale, first-class water heater production base in China, with an annual production capacity of more than 2 million water heaters and sterilizers, and the products sell well all over the country and Europe, America, Southeast Asia and other regions. >>>More
The efficiency of gas water heaters is usually about 90% (condensing type can even exceed 100%), and the efficiency of electric water heaters is generally above 90% (but considering the primary energy power generation efficiency is 45%, the primary energy efficiency of electric water heaters is about 40%), the air energy water heater is an air source heat pump, and the heating coefficient is generally about 5 (which can be approximated as the efficiency is 500%), and it is estimated that it can reach 3 under low temperature conditions in winter. The overall efficiency is about 5% based on a heating coefficient of 220%. >>>More
When choosing a water heater, safety should be considered first, and an electric water heater with 'electric wall' technology can be selected, even if there is leakage, it will be foolproof and will not cause harm to people. >>>More
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. >>>More
Natural gas water heaters are relatively more cost-effective, convenient and convenient, can also be used and washed, there is no time limit, the comfort is the best, suitable for every region in the north and south. However, it is relatively high, so it must be installed outside the shower, and it is convenient to pull the exhaust pipe to the outside, and it should be used frequently, if it is not needed for a long time, it is easy to have common failures. Household water heaters are divided into two types: storage type and instantaneous type, the application of water storage type must be electrified in advance, and the boiling water is limited by the volume size, which is not suitable for the application in North China, because the tap water quality in North China is hard, it is easy to produce dirt, and it is necessary to carry out the scale cleaning work regularly, otherwise it can not be used normally, and the use period is endangered. >>>More
