How to choose a water heater
As an indispensable electrical appliance in family life, water heaters need to consider multiple factors when choosing to ensure that you are purchasing a product that is suitable for your own use and cost-effective. Here’s a detailed guide to choosing a water heater:
1. Type of water heater
Electric water heater: It is divided into water storage type, instant heating type and rapid heating type, and there are various specifications of water storage capacity.
Gas water heater: heats water by burning gas, heating up quickly.
Solar water heater: Uses solar energy to heat water, saving energy and environmental protection.
Air energy water heater: absorbs heat from the air to heat water, with a high energy efficiency ratio.
For ordinary households, electric water heaters and gas water heaters are more common choices.
2. Liner selection
The inner liner of an electric water heater is one of its core components, which directly affects the service life of the water heater.
Seamless liner: It is integrated by deep drawing stamping process, which has strong pressure bearing capacity, long service life, and is not easy to corrode.
Ordinary three-stage liner: multi-section welding, poor pressure bearing, relatively short service life.
It is recommended to give preference to seamless liners, such as Haier’s all-ceramic diamond seamless liner, Midea enamel seamless liner, etc.
3. Heating tube selection
Single-tube heating: The heating power is usually within 2.5kW, and the heating time is long.
Dual-tube heating: Support dual-tube inverter heating, and the heating mode can be selected according to different water needs, and the heating speed is faster.
Double-tube heating models are usually positioned in the mid-range and have higher heating efficiency, so it is recommended to give preference to them.
4. Capacity selection
The capacity of the water heater should be selected according to the number of people in the family and water habits.
50L: Suitable for rental transition use or 1-2 person families.
60L: suitable for a family of 3 people.
80L and above: suitable for families of 4 or more.
5. Energy efficiency options
The energy efficiency rating of a water heater reflects its power consumption.
Level 1 energy efficiency: the highest energy efficiency ratio and the most energy-saving.
Level 2 energy efficiency: The energy efficiency ratio is slightly lower, but it is more energy-efficient than level 3 energy efficiency.
Level 3 energy efficiency and below: The energy efficiency ratio is average or low, and the power consumption is high.
It is recommended to choose according to the budget and actual needs, although the first-level energy efficiency is the most energy-saving, but the price is higher; Secondary energy efficiency is often a cost-effective option.
When choosing a water heater, in addition to considering the above factors, you should also pay attention to the after-sales service and user reviews of the product.
