3. Is it worth buying an indirect water heater?
Considering whether to buy an indirect water heater depends on your needs and the region you live in. If you fall into any of the following cases, opting for an indirect water heater will serve you and your family best:
1. You live in a cold climate area
In regions with cold climates, such as the Northern part of our country during winter, a water heater is essential. With temperatures dropping, hot water is frequently used in daily activities like bathing, dishwashing, laundry, etc.
2. Large family household
If your family has a significant number of members (4 to 5 people) and requires frequent hot water usage, an indirect water heater is a sensible choice. It provides enough hot water for the entire family while saving energy.
3. Low voltage area
In places with low electrical voltage, it is essential to use an indirect hot water tank to ensure the device has enough time and power to boil the water. This way, it can promptly meet the household needs.
Your home water pressure is low
Indirect hot water tanks ensure a fast and robust flow of hot water, even in places with low water pressure. Therefore, it is advisable to use an indirect water heater to save energy and enhance the quality of the water output.
4. Safe and Energy-Efficient Use of Indirect Hot and Cold Tanks
Choose a tank capacity suitable for the number of family members
The larger the tank capacity, the higher the operating power of the machine, which means higher electricity consumption. Therefore, choose a tank capacity that matches the usage needs and the number of family members. Specifically:
For families with 1 – 2 members, it's advisable to choose a tank with a capacity ranging from 15 – 20 liters. Families with 2 – 3 members should opt for a tank between 21 – 30 liters. Meanwhile, households with 3 or more members should consider using a hot and cold tank with a capacity above 30 liters to ensure it meets all usage needs.
Avoid keeping the tank on 24/7
Many households have the habit of keeping the hot and cold tank running all day to use it whenever the cold season arrives. However, this not only wastes energy but also reduces the lifespan and heating efficiency of the machine. It's recommended to turn on the tank about 10 – 15 minutes before showering for optimal performance.
