Water heaters are widely utilized in various applications, ranging from residential households to commercial establishments such as hotels, hospitals, and resorts, as well as certain large-scale industrial facilities. Today, water heaters have evolved into two main types: electric water heaters and gas water heaters, each with its own distinct advantages and limitations. Therefore, business operators should carefully select the type of water heater that best suits their specific industry and operational needs.
Gas water heaters are commonly used in residential buildings, hospitals, hotels, condominiums, and certain industrial facilities. Their key advantages include controllable hot water temperature, compact design, lower initial cost, and up to 60% energy savings compared to electric systems. These heaters are also designed with safety mechanisms and exhaust systems to ensure user safety. However, they do have some limitations, such as more complex installation requirements, and some users may have concerns regarding safety during operation.
Electric water heaters are commonly used in industrial plants or large buildings. They are generally divided into two types: storage (tank) systems and instant (tankless) systems.
The instant (tankless) type offers several advantages: it is easy to install, affordable, and user-friendly. The unit is designed with a direct heating element. Its working principle is that cold water flows through coiled copper pipes inside the unit, where the heated surface transfers heat to the water. However, since the water pipes are relatively small, there is a possibility of inconsistent water flow.
The storage (tank) type is equipped with a hot water tank that maintains a constant temperature, ensuring strong water flow and immediate availability. It often includes a mixing valve to combine hot and cold water for temperature adjustment. However, this type of electric water heater is generally more expensive than the instant (tankless) type.
In summary, whether choosing an electric water heater or a gas water heater, it is important to select the type that best suits the installation site and usage requirements to achieve maximum efficiency. Both types offer distinct advantages, as outlined above, along with differences in installation methods. For example, installing a gas water heater may involve slightly more complex procedures to ensure safe operation, but it has the advantage of being more cost-effective. This makes gas water heaters a popular choice for installation in various locations beyond just residential homes, as they help reduce overall costs.
For electric water heaters, proper piping must be prepared during installation. This type of water heater requires two water lines: one pipe supplying water into the heater and another carrying normal-temperature water connected to the mixing valve. When in use, both hot water from the heater and normal water flow through the mixing valve, allowing the desired temperature to be adjusted.
Therefore, it is common to see faucets with two handles that allow adjustment between hot and cold water. However, in terms of cost, electric water heaters are more expensive to operate because they consume more electricity, with some units using over 10,000 watts of power. Most importantly, caution must be taken to prevent hazards such as electric leakage or improper installation without grounding.
It is evident that water heaters come in various types, ranging from those used in residential homes to large-scale businesses.
