What is the best type of water heater to buy today?

A water heater is an essential device in every household, especially during cold days. With a variety of models, types, and brands available in the market, many consumers are unsure about the best type of water heater to buy today. Mytour Supermarket shares some tips to help you confidently choose the most suitable water heater for your family.

1. Factors to consider when choosing a water heater

1.1 Choosing between a direct or indirect water heater?

Direct water heater: This device heats water without using a storage tank. It utilizes electric resistor rods to heat water instantly within a few seconds. The maximum water heating temperature is around 45 – 55 degrees Celsius.

Indirect water heater: This device heats water using a storage tank to heat water to the set temperature within 5 – 15 minutes. Typically, the tank capacity is around 15 – 100L, and the heating time varies depending on the tank's power.

So if your family has few members, moderate water usage, and strong water pressure, you should use a direct water heater. In case your home has low water pressure but you still want to choose a direct water heater, choose a product with a built-in pressure-boosting pump to enhance water flow.

If your family has many members (5 – 8 people) or uses a bathtub, it is recommended to prioritize choosing an indirect water heater.

1.2 Choose a unit with an ELCB instead of a CB

Many people often mistake ELCB (Earth Leakage Circuit Breaker) for CB (Circuit Breaker), thinking it is a circuit breaker that only cuts off power after a circuit fault occurs. The ELCB, also known as the Earth Leakage Circuit Breaker, is a device placed inside the water heater. It has the function of detecting leaks and cutting off power to prevent any risk of circuit contact, electric shock, or explosion. 

Currently, water heaters equipped with ELCB, although more expensive than those using CB, are highly rated by users for safety. If you are still not confident in the ELCB device in the water heater, you can install an additional standalone ELCB device to ensure high safety, especially for direct water heaters. 

Choose a water heater with an installed ELCB to protect yourself and your family members

1.3 Choose an appropriate storage capacity

In general, there are 4 types of storage capacities for water heaters in the market for customers to choose from:

• 15-liter tank, suitable for 1 – 2 people.

• 20-liter tank, suitable for 2 – 3 people.

• 30-liter tank, suitable for 3 – 4 people.

• 45-liter tank, suitable for 4 – 5 people.

Depending on the number of family members, choose a water heater with an appropriate capacity to avoid waste. If you have a small family and only use a shower, consider a water heater with a 10, 15, or 30-liter tank. For larger families or those using a bathtub or supplying water to all faucets in the house, prioritize a water heater with a tank larger than 45 liters.

Before purchasing, you can gather information about the size and capacity of different water heaters online or seek advice from professionals to save time.

3. Some tips for choosing and using water heaters correctly

- Choose genuine products: Instead of buying cheap products with unclear origins, opt for genuine ones by checking the box, ensuring the barcode is not blurry, and the printing is clear. If it's authentic, the original label should contain all the necessary information: brand, place of manufacture, capacity, operating pressure, etc.

- Prioritize water heaters installed according to CEI – EN standards for electrical disconnection. Pay attention to the wiring system and grounding system to ensure safety for consumers.

- To avoid energy waste, you should only turn it on 10 – 15 minutes before bathing, not keeping it on 24/7.

- Regularly maintain the water heater, use an electrical tester on the water pipes. If there's an electric current, turn off the power and check the entire system to fix the issue.

Like any household appliance, before buying and using, you need to thoroughly research product information to avoid mistakes or regrets later. With these shared tips, hopefully, you can choose the best and most suitable water heater for your family.
