Direct water heaters are now commonly found in households. This product has almost become an indispensable part of every home, especially in cold seasons. However, do you really know about this product? What should you pay attention to? Or which brand of direct water heater is the best? Hopefully, the following information will help you understand more about this product.
1. What Is a Direct Water Heater? Structure and Operation Principle
A direct water heater is a compact and convenient product that uses an electric resistance rod to heat water and delivers hot water directly to the shower for use. With the advantage of rapid water heating, users can use it immediately without waiting. This type of machine also does not take up space because it does not have a water storage tank. Direct water heaters allow users to adjust the hotness level according to their needs and can heat water up to 40-45 degrees Celsius. However, it is not really an ideal product for regions with extremely cold climates.

2. Classification of Direct Water Heaters Currently Available on the Market
Direct water heaters come in various types, each with its own advantages and disadvantages. You must truly understand and refer to how to choose a safe and shock-resistant direct water heater to be able to decide which type is best for your family. Currently, there are two types of direct water heaters on the market: with and without pumps:
Direct water heaters nowadays are equipped with booster pumps. Products with this additional device have the advantage over those without a booster pump in that they make the water flow stronger.
So should you buy a machine with or without a pump? This depends on the needs of the members of your family and the distance between the water heater and your home's water tank. Machines equipped with booster pumps are suitable for every family and every need, especially for places with weak water supply. However, its disadvantage is that it is more expensive by a few hundred thousand compared to machines without a booster pump. Conversely, machines without pumps are relatively cheaper and should be used when the distance between the machine and the family's water tank is at least 5 meters. Because then the water flow is quite strong and stable due to sufficient pressure from above.
In addition to the two traditional types of direct water heaters with manual adjustment above, direct water heaters also use infrared technology combined with nano carbon-coated quartz to heat water. The advantage of this type is that it does not need to use electrical wires, so it is much safer and more economical than conventional water heaters. Moreover, this type also has a high antibacterial function, providing cleaner water, which is good for users. This is an electronic adjustable water heater with temperature display during use, so users can adjust and monitor the water temperature. At the same time, this product also has a remote control function.
So when should you buy an infrared water heater? Infrared water heaters are suitable for large families due to their significant energy savings. This type of machine is also suitable for households with damp bathrooms.
Determine your needs and water supply to choose the best type of direct water heater for your family.
