Description

At Water Heaters, we specialize in providing top-quality water boilers that cater to your specific hot water needs. Our shop is conveniently located at Westlands Commercial Centre, Block C, Second Floor. Whether you need a water heater for domestic use or other applications, we offer reliable solutions that guarantee consistent hot water supply at a single service point. One of the most popular options we provide is the non-pressurized water heater. This type of heater is ideal for homes where the residential water system has low pressure, typically ranging between 50 to 100 pounds per square inch (psi).

Understanding Non-Pressurized Water Heaters

A non-pressurized water heater is designed for areas with low water pressure. Unlike high-pressure systems, this type of heater holds water at low pressure and delivers hot water to a single service point, such as a bathroom or kitchen. Due to its construction and operating principles, it is perfect for residential settings where water pressure is limited.

Construction of a Non-Pressurized Water Heater

The construction of a non-pressurized water heater focuses on durability, safety, and energy efficiency. Here’s a closer look at its key components:

1. Heavy Inner Steel Tank

At the heart of this water heater is a heavy-duty inner steel tank, capable of holding 30 gallons of water. This inner tank is essential for storing hot water and is lined with a bonded glass liner that prevents rust from forming inside the tank. The rust-proof nature of the tank ensures that the water remains clean and the heater lasts for a long time.

The inner tank is enclosed by a lead outer tank, which is designed for additional durability. Between the inner and outer tanks, there is a layer of glass wool insulation. This insulation is vital in preventing heat loss, as it minimizes heat transfer between the two tanks. This insulation feature helps keep the water hot for longer periods, enhancing the energy efficiency of the unit.

2. Dip Tube for Cold Water Inlet

A dip tube is installed to allow cold water to enter the tank from the bottom. As cold water enters, the dip tube ensures that it stays at the bottom of the tank, preventing it from mixing with the hot water at the top. This design helps maintain the efficiency of the water heater. The dip tube is equipped with a shutoff valve, allowing for easy control of water inflow.

3. Hot Water

Outlet Pipe** The outlet pipe in a non-pressurized water heater allows the heated water to flow out from the top of the tank. This pipe ensures that the hottest water, which rises due to its lower density, is available when needed.Non-Pressurized Water Boiler (136Lts). The outlet pipe is directly connected to the service point, such as a sink or shower, ensuring a steady supply of hot water on demand.

4. Thermostat for Temperature Regulation

A thermostat is incorporated to regulate the temperature of the water in the tank. This device allows you to adjust and maintain the desired water temperature, typically set between 120°F and 140°F (49°C to 60°C). These temperatures are ideal for household use, preventing scalding while also optimizing energy consumption.

The thermostat automatically controls the heating element, cutting off power when the desired temperature is reached, and reconnecting when the water cools down. It is usually located under a cover plate with an adjustable knob or screw to set the temperature easily.

5. Heating Element for Water Heating

The heating element is the core component responsible for heating the water. It draws electricity to generate heat, which in turn heats the water inside the tank. When the electric supply is turned on, the heating element warms the water, and the thermostat ensures that the desired temperature is reached efficiently. The separation of hot and cold water within the tank ensures a consistent supply of hot water at the outlet.

6. Drain Valve for Easy Maintenance

The drain valve provides a means to easily drain the tank when necessary, such as for maintenance or replacing the heating element. Draining the tank periodically helps to remove sediment buildup, which can reduce the efficiency and lifespan of the water heater. This feature makes it easy to perform regular upkeep without the need for professional assistance.

7. Pressure Relief Valve for Safety

Safety is a top priority in water heater design, and the pressure relief valve is a critical feature that protects the tank from excessive pressure. This valve monitors the internal pressure of the tank, and if the pressure exceeds safe limits, the valve automatically releases water to prevent the tank from exploding. This feature ensures the safe operation of the heater and adds an essential layer of protection.

8. Sacrificial Anode Rod to Prevent Corrosion

To protect the steel tank from corrosion, a sacrificial anode rod is installed. This rod is typically made of magnesium or aluminum and is designed to attract corrosive elements in the water. As these elements corrode the anode rod, they are prevented from attacking the steel tank. Over time, the anode rod will need to be replaced to continue protecting the tank from rust and corrosion.

Working Principle of a Non-Pressurized Water Heater

The non-pressurized water heater works based on the simple principle that heat rises. When the heating element is activated, it heats the water in the tank. As the water heats up, it becomes less dense and rises to the top of the tank. The colder, denser water remains at the bottom and is continuously heated by the element.

When cold water enters the tank, it is directed to the bottom via the dip tube, ensuring that the hot water at the top remains undisturbed. This process allows for a consistent supply of hot water, with the thermostat maintaining the temperature to prevent overheating or cooling.

The thermostatic switch automatically disconnects the power to the heating element once the water reaches the pre-set temperature. If the water cools below the set level, the switch reconnects the power, reheating the water as needed. This automatic regulation ensures that energy is not wasted, keeping utility costs low.

Energy Efficiency and Environmental Impact

One of the standout features of a non-pressurized water heater is its energy efficiency. The glass wool insulation surrounding the inner tank helps to minimize heat loss, meaning the water remains hot for longer periods without requiring continuous heating. This not only conserves energy but also reduces your monthly electricity bills, making it a cost-effective and environmentally friendly solution.

Additionally, the thermostat’s ability to regulate the temperature ensures that the water heater only consumes energy when necessary, further enhancing its efficiency. By using a sacrificial anode rod, the steel tank is protected from corrosion, reducing the need for repairs or replacements and extending the heater’s lifespan.

Installation and Maintenance

Installing a non-pressurized water heater is straightforward, and most models come with an easy-to-follow instruction manual. At Water Heaters, we provide  within Nairobi, and our team can assist with installation upon request.

To ensure your water heater functions optimally, regular maintenance is recommended. Some key maintenance tasks include:

  • Inspecting the anode rod: The sacrificial anode rod should be checked regularly and replaced as necessary to prevent tank corrosion.
  • Draining the tank: Periodically draining the tank helps remove sediment buildup, improving the efficiency of the heating element.
  • Cleaning the exterior: Wipe down the tank with a soft cloth and mild cleaning solution to keep it looking new. Avoid abrasive cleaners, which could damage the surface.
  • Testing the pressure relief valve: Ensure the valve is functioning correctly to avoid any safety hazards.

Conclusion

A non-pressurized water heater is an excellent choice for households with low-pressure water systems. Its reliable performance, advanced safety features, and energy-efficient operation make it a practical and durable solution for your home’s hot water needs. At Water Heaters, we are committed to providing top-quality water heaters that combine efficiency, safety, and affordability.
