Introduction of Heter tank booster

A water heater tank booster is a device that can be installed on a traditional tank-style water heater. It enhances the amount of hot water available for use. The device works by mixing hot water from the tank with cold water. Yet, this increases the volume of hot water available. Moreover, it also extends the time the hot water stays hot.

The water heater tank booster consists of a thermostatically controlled mixing valve. This valve will be installed on the hot water outlet of the water heater tank. The valve mixes the hot water with cold water to achieve the desired temperature and volume of water. The booster adjusts to provide the required temperature that meets the home’s needs.

Water heater tank boosters are beneficial for larger households. It is also helpful for those with high hot water demand. They can help to prevent the need for a larger, more expensive water heater. They also improve the existing water heater’s efficiency by lowering the time it takes to heat the water.

Why do we need a water heater tank booster?

A water heater tank booster increases the amount of hot water available from a hot water tank. This is achieved by increasing the water temperature in the tank to a higher temperature than the standard setting.

By increasing the water temperature in the tank, the booster allows the hot water to last longer before running out. It can be beneficial during peak usage times like mornings and evenings.

Maintaining a higher temperature in the tank requires less energy to heat the water as it is used. This will result in lower utility bills over time.

Temperature required for tank booster.

The temperature required for a tank booster can vary depending on the specific model and application. Yet, in general, tank boosters are designed to maintain a safe and suitable temperature at the tap.

The recommended temperature for a tank booster is usually around 120°F (49°C). This temperature is hot enough to provide a comfortable shower or bath. Yet, it also prevents scalding. This temperature adjusts as needed to suit your specific needs and preferences.

It is vital to note that temperatures above 120°F can increase the risk of scalding. It mainly reduces the risk in children and people with sensitive skin. Additionally, temperatures above 140°F can cause severe burns in seconds. So, it is recommended to keep the temperature of your tank booster at or below 120°F for safety and comfort.

How does the water heater tank booster work?

A water heater tank booster works by mixing warm water from the tank with cold water to achieve a higher volume of usable hot water. Here’s how it works:

A water heater tank booster, often referred to as a “hot water booster” or “thermostatic mixing valve,” is a device designed to increase the capacity of a traditional water heater without the need to invest in a larger tank. It does this by regulating the temperature of the stored water, allowing it to be stored at a higher temperature and then mixed with cold water when being dispensed to ensure safe and consistent temperatures. Here’s a step-by-step explanation of how it works:

  • Storing Water at Higher Temperatures:
    • Without a booster, most residential water heaters are typically set to store water at 120°F (49°C) to prevent the risk of scalding.
    • With a tank booster, the water heater’s thermostat can be increased to store water at a much higher temperature, often around 140°F (60°C) or more. This higher temperature helps in reducing the risk of Legionella bacteria growth, which can cause a form of pneumonia known as Legionnaires’ disease.
  • Mixing Hot with Cold:
    • When you open a hot water tap in your home, the water from the heater, now at a higher temperature, flows into the mixing chamber of the tank booster.
    • Simultaneously, cold water is also introduced into this mixing chamber. The tank booster then mixes these two streams, producing water at a safe, consistent temperature, usually around 120°F (49°C), before it is sent to your tap.
  • Increased Effective Capacity:
    • Because the water is stored at a higher temperature and mixed with cold water before it reaches the tap, you effectively get more hot water than the tank’s rated capacity. For example, a 40-gallon tank can supply the equivalent of 60 gallons or more of usable hot water when using a tank booster.
  • Safety Features:
    • A tank booster often includes a built-in check valve to prevent mixing hot and cold water in the storage tank itself, ensuring the stored water remains at the desired high temperature.
    • Many tank boosters also have adjustable temperature settings, so you can select the exact output temperature you desire, providing more control and ensuring the water is safe for all users.
  • Energy Efficiency:
    • By allowing the tank to store hot water at higher temperatures, the frequency of the burner or heating element turning on can be reduced, leading to potential energy savings.
  • Prevention of Legionella Growth:
    • Storing water at higher temperatures significantly reduces the risk of Legionella bacteria growth in the tank, providing a safer water supply.

A water heater tank booster is an efficient solution for households frequently running out of hot water, especially during peak usage. By increasing the effective capacity of the water heater without replacing the entire unit, homeowners can enjoy longer hot showers and reduce the wait time between them.

Increased Volume:

Mixing hot water from the tank with cold water increases the volume of usable hot water. This means more hot water is available and less need to wait for the tank to reheat.

Temperature Control:

The mixing valve ensures that the mixed water is delivered at a consistent temperature. Yet, this can be adjusted to meet the needs of the household.

Tank booster helps to increase the efficiency of a traditional tank-style water heater. It provides more hot water without needing a larger or more expensive water heater. It can benefit households with high hot water demand or larger families.
