Understand in 1 minute, teach you how to choose a water heater
Home decoration and the choice of home appliances are always a headache. Today we will talk about the purchase of water heaters. Many homeowners don’t know how to choose a water heater. After moving in, they find that the water heater they installed does not meet the needs of their family members. In fact, it is enough to look at the following points when choosing a water heater. You can understand it in one minute. Choose the water heater correctly.
Part 1: Classification of Water Heaters
According to the heating method: electric water heater and gas water heater
1) Electric water heater: It is divided into storage type electric water heater and instant electric water heater. In the practical application of the family, the storage type electric water heater is more common.
Many owners are more worried about the safety of electric water heaters, especially instant electric water heaters, when they see that many electric water heaters have caused electric shocks recently. In fact, if it is a qualified product of a big brand, basically there is no need to worry about the safety of use, and the safety problem of electric shock is generally caused by reasons such as long service life and aging circuit.
Instantaneous electric water heaters have higher power and are closer to the water. In the consciousness of most people, their safety risk is greater than that of storage electric water heaters. Although we firmly believe that the safety guarantees of big brands are relatively in place, but in In the actual choice, I personally would not choose an instant electric water heater.Also read:Best Water Heaters of 2022
2) Gas water heater: I choose a constant temperature gas water heater for my home, but there are several constant temperature methods, the more popular ones are: water and gas double adjustment, water volume server constant temperature.
The water-gas double-adjustment constant temperature method controls the temperature by controlling the water intake and the size of the gas valve. In this constant temperature method, the water temperature range is generally within 1 degree, and families with low requirements can basically meet the use;
The constant temperature method of the water volume servo is also a water-gas dual adjustment method. It controls the size of the water flow through the stepping motor to control the opening and closing of the spool. When used with a gas proportional valve, a better constant temperature effect will be achieved. Generally, the water volume servo The temperature difference achieved by the constant temperature method is within 0.1 degrees, and the constant temperature effect is better.
Part Two: How to Choose a Water Heater
The purchase of water heaters should not blindly follow the trend. Gas water heaters with constant temperature and water volume servers are good, but you must also consider factors such as budget and family space layout to choose water heater products suitable for your family.
1) Choose according to the number of family members
For a family of three or four, any type of water heater can meet the needs of the family; but if there are many family members, it is recommended to choose a gas water heater, because the water storage capacity of the electric water heater may not be enough for the family.
Although instant electric water heaters can also be used by multiple households, due to the small market share and many people still feel that instant electric water heaters have safety problems in electricity use, they are no longer recommended here.
2) The kitchen is far from the bathroom
It is recommended to choose a storage-type electric water heater. If you choose a gas water heater, because the pipeline is longer, there will be more cold water in the middle, unless your home needs to install zero-cold water and multiple pipelines (it will cost more).Also read:Best 8 Portable Water Heaters for RV or Camping
3) The kitchen is small
Give priority to electric water heaters. Gas water heaters should be installed in the kitchen. If the kitchen space itself is small, don’t think about installing such a large gas water heater in the kitchen, unless your bathroom space is also small.
4) I want zero cold water but it is inconvenient to install a gas water heater
You can consider using it with a small kitchen treasure.
5) Selection of constant temperature method of gas water heater
Water and gas dual-adjustment constant temperature and water volume server constant temperature, both types of water heaters can be considered, but if there are children and elderly people in the family who are sensitive to water temperature and temperature differences, it is recommended to choose a gas water heater with a water volume server constant temperature.
6) Selection of water heater capacity
The gas water heater is recommended to start with 16L, because many families now emphasize the bathing experience and use a shower with a large water output. 16L can meet the bathing requirements of most families.
If you want to calculate it specifically, you can look at the configuration of your shower. The liters of a gas water heater refers to how many liters of water can be raised by 25 degrees per minute. If the temperature increase in our use scenario is 25 degrees, the top spray flower The amount of sprinkled water is generally 10-15L/min, and the amount of water sprayed by hand is 5-10L/min. There are two bathrooms, one with top spray and the other with hand spray, adding up to 15-20L. It is indeed necessary to start with 16L. In fact, according to this calculation method, according to the configuration of the family bathroom, it is also possible to easily calculate how many liters of gas water heater should be used.
The choice of liters of electric water heater: about 40 liters can meet the continuous use of a family of two, and 60 liters can basically meet the continuous use of a family of three.
