Non-Pressurized Water Boiler (272L DB)

Non-Pressurized Water Boiler (272L DB): An Efficient Solution for Low-Pressure Water Systems

The Non-Pressurized Water Boiler (272L DB) is an ideal solution for households where hot water is required at just one service point. This type of boiler is designed to hold water at a lower pressure, which is why it is referred to as a Non-Pressurized Water Boiler. It’s particularly useful in homes where the residential water system’s pressure is low, typically ranging from 50 to 100 pounds per square inch (psi).

This type of water boiler is efficient, reliable, and specially designed to meet the needs of households or locations with low water pressure. It provides consistent hot water while also ensuring safe operation and minimal maintenance requirements.

Construction of the Non-Pressurized Water Boiler

The Non-Pressurized Water Boiler (272L DB) boasts a sturdy and thoughtful design that contributes to its functionality and durability. Let’s break down the construction of this unit:

  1. Heavy Inner Steel Tank: The heart of the system is its heavy inner steel tank, which is designed to store hot water. This tank typically holds between 40 to 60 gallons of water, making it an excellent choice for medium to large households. The inner tank is made from high-quality steel, which ensures durability and long-term reliability.To prevent rust and corrosion, the steel tank is usually lined with a bonded glass liner. This ensures that the water remains clean and rust-free, maintaining the quality of the hot water that comes out of the boiler. Surrounding this inner steel tank is an outer tank, typically made of lead.The space between the inner and outer tanks is insulated with glass wool, which acts as a thermal barrier to minimize heat loss. This feature ensures that the water inside the tank stays hot for extended periods, reducing the need for frequent reheating and thereby saving energy.
  2. Dip Tube: A dip tube is installed to allow cold water to enter the tank. The dip tube is accompanied by a shutoff valve, which helps regulate the flow of water into the tank. Cold water is directed to the bottom of the tank through the dip tube, ensuring that the hot water stays at the top for easy access.
  3. Outlet Pipe: An outlet pipe is provided to allow the hot water to exit the tank. This pipe is strategically positioned at the top of the tank where the hot water naturally rises due to its lower density compared to cold water.
  4. Thermostat: The thermostat plays a crucial role in controlling the temperature of the water inside the tank. It allows users to set the desired temperature, ensuring a balance between comfort and energy efficiency. The thermostat typically allows the temperature to be set between 120°F and 140°F (49°C to 60°C), which is considered the optimal range for both safety and energy savings.In addition to controlling the water temperature, the thermostat includes a thermostatic switch that disconnects the power supply when the set temperature is reached. This switch helps prevent overheating and ensures the water heater operates efficiently.
  5. Heating Element: A powerful heating element is responsible for heating the water inside the tank. When the electric supply is turned on, the heating element generates heat, which in turn raises the temperature of the water. The heating element is designed to be efficient and durable, ensuring consistent hot water even in low-pressure environments.
  6. Drain Valve: The drain valve allows the tank to be drained when necessary, such as during maintenance or when replacing the heating element. This feature simplifies the process of cleaning and maintaining the boiler, ensuring it operates smoothly over time.
  7. Pressure Relief Valve: Safety is a priority in the design of the Non-Pressurized Water Boiler (272L DB). A pressure relief valve is provided to prevent the tank from over-pressurizing. This valve automatically releases water if the pressure in the tank exceeds safe levels, ensuring the boiler doesn’t explode or suffer damage.
  8. Sacrificial Anode Rod: To prevent the steel tank from corroding, the boiler includes a sacrificial anode rod. This rod is made from a more reactive metal than the steel tank and will corrode first, protecting the tank from rust. Over time, the anode rod will degrade and need to be replaced, but this simple component significantly extends the lifespan of the water heater.

Working Mechanism of the Non-Pressurized Water Boiler

The Non-Pressurized Water Boiler (272L DB) operates using the basic principle of heat rises, which effectively separates the hot water from the cold water inside the tank.

When electricity is supplied to the heating element, it generates heat that is transferred to the water. As the water heats up, it becomes less dense and rises to the top of the tank, where the outlet pipe is located. Cold water, being denser, remains at the bottom of the tank and is continuously heated by the element.

The heating element monitors the temperature of the water and ensures that it remains within the preset range. When the temperature reaches the set point (typically between 120°F and 140°F), the thermostatic switch disconnects the power to prevent overheating. If the temperature drops below the set point, the thermostat will reconnect the power and the heating element will resume heating the water.

This process ensures that the water is always kept at the desired temperature, providing a steady supply of hot water when needed. By maintaining a consistent water temperature, the boiler offers both comfort and energy efficiency.
