Liters of gas water heater
Gas water heaters do not store water, so the liters of this water heater cannot be compared to those of storage type electric water heaters.
If explained using a scientifically rigorous formula, the "liter" of a gas water heater refers to its hot water flow rate per minute, which is equal to (△ T25 ℃ × X flow rate) ÷ Y set temperature. However, this is not easy to understand. We can simply understand it as the amount of hot water flowing out per minute that meets the corresponding conditions. So we can roughly assume that a 16 liter gas water heater can provide us with the hot water that a 40 liter storage electric water heater would take 40 minutes to burn in just 2.5 minutes.
How many liters is suitable for household gas water heaters
If you insist on me simplifying this number of liters, a home with two bathrooms and a kitchen usually uses an 11 liter gas water heater. However, depending on various conditions, 16 liters is still considered safer.
Firstly, the size of a gas water heater is related to the size of the household population. The more people there are, the greater the chance of using hot water at the same time. Simultaneously using hot water requires gas water heaters to provide a large amount of water flow in a short period of time, and the heating speed should also be fast.
Secondly, the number of bathrooms also directly affects this standard. There are many bathrooms, so there is a greater chance of using water at the same time. If it is a dual bathroom, it is best to use a gas water heater with a capacity of 14 liters or more. If there are multiple duplex buildings or bathrooms, up to three or four, it is recommended to use water heaters with a capacity of 16 liters or more, such as 20 liters, 24 liters, or 32 liters. In terms of large liter water heaters, Linne, Nengli, and Bailiman have done a better job.
Another important parameter is the distance between the gas water heater and the water usage location. The farther the distance, the greater the required number of liters. Because there is a significant amount of heat loss during the transportation of water, which also requires faster heating to compensate for.
Do you have a bathtub at home? If you enjoy taking baths, the liter capacity of the gas water heater needs to be increased. Because you may need to pour a large amount of hot water into the bathtub in a short amount of time. Of course, if you enjoy showering, the nozzle you are using alone needs to achieve a water output of 6-8 liters per minute to make you feel comfortable. If there is also someone who needs water at the same time, the amount of water used will have to be accumulated.
In addition to the above reasons, the season in which you use the water heater and your requirements for the temperature of the hot water also affect this' liter count '. When taking a hot shower in the cold Northeast and a cool shower in the hot Guangdong require the same amount of bath water, the gas they need will definitely not be the same, and of course, the number of liters of gas water heaters they need will also not be the same.
In summary, our region belongs to the north, and the temperature and water temperature are low in winter, so the temperature needs to be higher. Generally, it is best to use a gas water heater with a capacity of 11 liters or more for non single households in one kitchen and one bathroom, and a gas water heater with a capacity of 14 liters or more for one kitchen and two bathrooms.
