There are three prerequisites for installing a gas water heater:
1. Gas is used at home, or gas can be used in a short time after decoration;
2. Because the gas supply volume of gas is related to the water outlet of the gas water heater, the larger the gas supply volume, the more water outlet of the gas water heater. Conversely, the gas supply volume does not meet the requirements of the water outlet of the gas water heater, and the gas water heater cannot be used. Therefore, it is necessary to select the water outlet of the gas water heater based on the gas meter. For details, please refer to the following table:
G1.6 mode: gas supply 0.016-2.5m/h, and can install a water heater with a water outlet of 13L or less;
G2.5 mode: gas supply 0.025-4m/h, and can install a water heater with a water outlet of 16L or less;
G4 mode: gas supply 0.04-6m/h, and can install a water heater with a water outlet of 20L or less.
3. The commonly used gases include liquefied petroleum gas , natural gas , gas, etc. The density and pressure of each gas are different. The nozzles in the corresponding gas water heater are different. Therefore, before purchasing a gas water heater, you need to understand the type of gas and choose the corresponding gas water heater.
So when decorating a new house, the most important thing is to look at the installation conditions at home. Whether it is suitable for installing a gas water heater or an electric water heater.
If the home has the conditions to install an electric water heater and a gas water heater, which water heater is better to choose?
Let’s compare the safety, cost of use, comfort, and convenience of use.
1, Security
The main danger of electric water heaters is electricity leakage. In recent years, due to irregular electric water heaters, leakage accidents occurred frequently. Nowadays, most domestic electric water heaters have anti-electric walls, and foreign electric water heaters mostly use power outage protection and other safety measures, which greatly improves the safety of electric water heaters. In addition, the current new houses are protected by ground wire and equal-position lines. As long as it is an electric water heater from a regular manufacturer, the safety is greatly guaranteed when the installation is standardized.
gas water heater main danger is carbon monoxide poisoning or hypoxia. In the early years, gas water heaters were mainly discharged directly, and combustion required the consumption of oxygen in the room, which led to the risk of hypoxia or carbon monoxide poisoning in some gas water heaters installed in confined spaces (such as bathrooms).
The current gas water heaters are mainly mainly strongly discharged, with higher combustion efficiency and cleaner exhaust gas emissions. They are mainly installed in non-confined spaces such as kitchens. As long as you pay attention to ventilation during use, there is basically no danger.
Therefore, in terms of safety, whether it is an electric water heater or a gas water heater, as long as it is a regular brand product, it has the national CCC certification mark and is installed in a standardized manner, there is no need to worry.
2, cost
In terms of price, electric water heaters are relatively cheaper, generally around 1,000 yuan, and gas water heaters are relatively high, mostly between 2-3,000 yuan. Due to different functions, models, etc., it is not very comparable.
In terms of usage cost, electric water heaters usually cost about 5 yuan to heat 200L of water, and gas water heaters usually cost no more than 4 yuan. In comparison, gas water heaters will save more money. In addition, electric water heaters need to be maintained regularly, replace magnesium rods , clean up the mud and sand in the water tank, etc., and the cost of use is higher than that of gas water heaters.
3, Comfort
Gas water heater is an instant hot water heater, which is heated while using it. Mid- and low-end models are often affected by water pressure, water use in multiple places, and there are frequent cold and hot situations. Gas water heater with water volume servo can solve this situation, but the price is relatively high.
electric water heater needs to be heated in advance before use, usually about half an hour to one hour. If the amount of water is sufficient, the water temperature will be constant and the experience will be better; but if the water is large, the capacity of the electric water heater is relatively small, and you need to wait for heating in the middle, which is relatively time-consuming.
Therefore, the water temperature of the gas water heater with a water volume server is constant, but the price is relatively expensive; the water temperature of the electric water heater is constant, but it is limited by capacity, so when purchasing an electric water heater, try to choose a product with a larger capacity.
4. Installation environment
Electric water heater is affected by capacity and has a relatively large volume, which has certain requirements for the load bearing of the wall; gas water heater is small in size and occupy a relatively small area, so it is usually necessary to choose a room with better ventilation to install it. Electric water heaters are usually installed in the bathroom, requiring more than 4 square meters of wires, 16A sockets, etc.; gas water heaters are usually installed in the kitchen, and need to connect to the flue to emit exhaust gas or directly discharge the exhaust gas to the outdoors.
Overall, the experience of using gas water heaters and electric water heaters is actually comparable, but if you have gas at home, it is more convenient to choose a gas water heater;
electric water heaters do not have high requirements for the installation environment, and when the number of people using water heaters in the family is relatively small, it is enough to install a 60-80L electric water heater;
If there are many people in the family, it is more convenient to use gas water heaters, especially gas water heaters with water volume servers, which have a better experience.
