Non-Pressurized Water Boiler(45Litres)
Non-Pressurized Water Boiler: Efficient Hot Water Solution for Low-Pressure Systems
A Non-pressurized water heater is designed to provide hot water at a single service point in homes or small spaces where the pressure of the residential water system is low, typically ranging between 50 to 100 pounds per square inch (psi). Unlike high-pressure water heaters, this type is ideal for households that do not require hot water distribution across multiple outlets, making it a practical and cost-effective solution. This water heater holds water under low pressure and operates efficiently to meet the hot water needs of homes or areas with limited water pressure.
Construction of a Non-Pressurized Water Heater
The construction of a non-pressure water heater is robust and designed to ensure both functionality and durability. The key components include:
1. Heavy Inner Steel Tank
The inner steel tank holds the hot water and is typically designed to store about 5 gallons of water. To prevent corrosion and rusting of the steel tank, a bonded glass liner is used. This liner keeps the water free from rust, ensuring clean, uncontaminated water at all times. Surrounding the inner steel tank is the outer lead tank, and between these two layers is an insulating material, typically glass wool. This insulation minimizes heat transfer, helping to maintain the water’s temperature for a longer period without the need for constant reheating, thus saving energy. Non-Pressurized Water Boiler
2. Dip Tube for Cold Water Inlet
A dip tube is installed to allow cold water to enter the bottom of the tank. The cold water enters through this tube, which works alongside a shutoff valve that allows you to control the flow of water entering the tank. This ensures that the water is replenished efficiently while the tank is in use.
3. Hot Water Outlet Pipe
The hot water is delivered through a hot water outlet pipe, which draws the heated water from the top of the tank, where the hottest water naturally accumulates due to the principle that heat rises. This ensures that the user always has access to the hottest water from the tank when needed.
4. Thermostat for Temperature Control
A thermostat is a crucial component of the water heater. It regulates the temperature of the water inside the tank, allowing you to set the desired temperature level. Most thermostats come with a range that can be adjusted between 120°F to 140°F (49°C to 60°C), ensuring a balance between safety and energy efficiency. Keeping the water temperature within this range prevents scalding while also conserving energy.
5. Heating Element
The heating element is responsible for raising the temperature of the water inside the tank. When electricity is supplied to the heating element, it heats up and transfers that heat to the water. The heating element works efficiently to quickly raise the temperature of the cold water that enters the tank.
6. Drain Valve
A drain valve is installed to allow for easy draining of the tank when necessary. This is particularly useful for routine maintenance, such as replacing the heating element or cleaning the tank. Draining the tank ensures the system remains clean and efficient, extending the water heater’s lifespan.
7. Pressure Relief Valve
To prevent the tank from exploding due to excessive pressure, a pressure relief valve is installed. This valve monitors the pressure within the tank and releases water when the pressure exceeds safe limits. This safety feature is crucial for preventing accidents and ensuring the safe operation of the heater.
8. Sacrificial Anode Rod
A sacrificial anode rod is used to protect the inner steel tank from corrosion. Over time, water can cause the steel to corrode, but the anode rod, made from materials like magnesium or aluminum, attracts the corrosive elements in the water, effectively “sacrificing” itself to protect the tank. This rod helps extend the lifespan of the tank by preventing rust.
How a Non-Pressure Water Heater Works
The working mechanism of a non-pressurized water heater is based on the natural principle that heat rises. When the heating element is activated, it generates heat, causing the water in the tank to warm up. Since hot water is less dense than cold water, it naturally rises to the top of the tank, while the cooler water stays at the bottom. As more cold water enters the tank through the dip tube, the hot water is pushed out through the outlet pipe, ensuring a continuous supply of hot water.
The thermostat plays an essential role in maintaining the desired water temperature. Once the water reaches the preset temperature, the thermostat automatically cuts off the power to the heating element, preventing overheating. When the temperature drops, the thermostat reconnects the power, allowing the heating element to resume heating the water.
It is generally recommended to set the thermostat between 120°F and 140°F to balance energy consumption and safety. Keeping the water at this temperature range helps prevent excessive energy usage while also minimizing the risk of scalding.

Additional Safety and Performance Features
This water heater also includes safety mechanisms that ensure its reliable and secure operation:
- The pressure relief valve prevents dangerous pressure buildup, protecting both the appliance and the user.
- The sacrificial anode rod extends the life of the steel tank by preventing rust.
- The anti-corrosion coatings used in the construction of the tank further enhance its durability, ensuring that it remains functional for an extended period.
Maintenance and Care Instructions
To ensure the optimal performance of your non-pressurized water heater, regular maintenance is essential. Here are some care tips:
- Regularly drain the tank: Periodically draining the tank helps remove sediment buildup, which can affect heating efficiency and lead to premature wear of the heating element.
- Check the anode rod: Inspect the sacrificial anode rod periodically and replace it when necessary to prevent corrosion of the tank.
- Clean the exterior: Wipe the surface of the water heater with a soft cloth and a mild cleaner to maintain its appearance. Avoid abrasive materials that can damage the finish.
- Test the pressure relief valve: Ensure the pressure relief valve is functioning correctly to prevent excessive pressure buildup inside the tank.
