Some washing machines require a booster heater to reach the high temperatures needed for effective cleaning and sanitizing of laundry. Booster heaters quickly raise water temperatures, helping washing machines tackle tough stains and maintain optimal wash cycles.
In this article, we’ll explore why some washing machines require a booster heater, how these devices are essential, and how they work.
Quick Summary
• Booster heaters in washing machines elevate water temperature to between 180 and 195 degrees Fahrenheit, crucial for effective cleaning, stain removal, and sanitation.
• Booster heaters are particularly beneficial in modern washing machines that use cold fill systems, enabling rapid heating of incoming cold water and ensuring consistent high temperatures throughout the wash cycle.
• Maintaining a stable water temperature with booster heaters improves energy efficiency, enhances detergent performance, and significantly improves cleaning and sanitation outcomes.
What is a Booster Heater?
A booster heater is a specialized type of hot water heater designed to elevate already warm water to higher temperatures, typically between 180 and 195 degrees Fahrenheit, for effective rinsing and sanitizing.
These devices are commonly used in commercial dishwashers to ensure proper cleaning and sanitation of dishware.
In the context of washing machines, booster heaters play a critical role in achieving the high temperatures needed for thorough cleaning and sanitation.
How Booster Heaters Work?
Booster heaters work by taking cold or pre-heated water and further increasing its temperature to the required levels for sanitizing and effective cleaning. This process is vital for breaking down tough stains and ensuring thorough cleaning, especially in heavily soiled clothes.
The heater works by circulating the hot and cold water through its system, raising the temperature quickly and efficiently.
In washing machines, the use of booster heaters ensures that the water temperature is consistently high enough to meet the demands of various wash cycles.
This stability is crucial not only for cleaning performance but also for energy efficiency, as it prevents the need for the machine to continually reheat water throughout the cycle.
Necessity of Booster Heaters in Washing Machines
A water heater or booster is a vital component in many dishwashers, especially for high-temperature wash cycles and cold-fill systems.
1. High-Temperature Wash Cycles
High-temperature wash cycles are often required for effective cleaning and sanitization in clothes washers. Elevated temperatures ensure grease and tough stains are effectively removed, especially from heavily soiled clothes.
Booster heaters enable washing machines to achieve these high temperatures quickly and consistently, making sure that the water is hot enough to break down tough stains and maintain an effective wash and sanitize cycle.
2. Cold-Fill Systems
Booster heaters are particularly important in modern washing machines that use cold-fill systems. These machines draw in cold water and rely on internal mechanisms to heat it to the desired temperature.
Booster heaters rapidly raise the temperature of the incoming cold water, ensuring that the washing machine can perform effectively without depending on the home’s hot water supply.
This rapid heating is essential for achieving the high temperatures needed for proper sanitation and effective cleaning.
3. Energy Efficiency Considerations
Booster heaters contribute to energy efficiency by heating water directly at the point of use, reducing the need for large, central water heaters and minimizing heat loss during water transit.
This localized heating approach ensures that water is only heated when necessary, leading to significant energy savings and making these heaters energy efficient compared to traditional water heating systems that maintain a large volume of hot water.
Sizing and Selecting a Booster Heater
When selecting a booster heater, it’s important to consider both the size and the features that will best suit your needs. Let’s explore how to determine the right size and the key features to look for in a booster heater.
1. Determining the Right Size
To determine the right size booster heater, you need to know the gallons per hour (GPH) of water used by your washing machine and the temperature rise required. Start by identifying the temperature of the incoming water and the desired temperature rise.
Use the formula: ([GPH of water used] x [Desired temperature rise]) / 400 = [Estimated kW] to calculate the necessary power. This calculation will help you select a booster heater that can efficiently meet the demands of your washing machine.
2. Key Features to Look For
When selecting a booster heater for your automatic dishwasher, consider features such as temperature control and display options. Some models offer electronic controls and digital displays, allowing for precise setting of water temperature required by your washing machine or sanitation codes.
Additionally, look for features like low water cut-off, which prevents the booster heater from overheating by running dry and can alert the operator to possible leaks. Tank design is also important, with options like cement-lined steel or stainless steel providing durability and efficiency.
Maintenance and Troubleshooting
Routine inspections can prevent breakdowns and extend equipment life. Let’s explore some regular maintenance practices and common issues with their solutions.
1. Regular Maintenance Practices
Routine maintenance is crucial for the longevity and efficiency of booster heaters, focusing on inspection, lubrication, electrical connections, and cleaning. Regularly inspect booster heater components to identify signs of wear and address them promptly.
To maintain your equipment, follow these steps:
• Lubricate moving parts to reduce friction and wear, ensuring smooth operation.
• Check electrical connections to ensure they are secure and functioning properly.
• Regularly clean the lime buildup in the tank to prevent heating elements from splitting and burning out.
2. Common Issues and Solutions
Improper water heating in booster heaters can be caused by factors such as dry-fired elements, blown fuses, or tripped circuit breakers. Scaling can build up in booster heaters, affecting their efficiency. Regular descaling can mitigate this issue.
Blocked or dirty filters can lead to malfunctions, so ensure they are clean and free from debris. If you hear a chattering sound from the contactor, it could be due to loose connections or low voltage. Address these issues promptly to maintain the efficiency and safety of your booster heater.
FAQs
Are there Specific Types of Dishwashing Machines that Require Booster Heaters?
Yes, high-temperature commercial dishwashing machines typically require booster heaters. These machines rely on very hot water to sanitize dishes without the need for chemical sanitizers.
How Do I Know If My Dishwashing Machine Needs a Booster Heater?
You can determine if your dishwashing machine needs a booster heater by checking the manufacturer’s specifications and the local health department’s requirements. If you are operating in a commercial setting where hygiene standards are strictly enforced, having a booster heater may be mandatory.
How Do Booster Heaters Contribute To Energy Efficiency?
Booster heaters contribute to energy efficiency by heating water directly at the point of use, reducing the reliance on central water heaters and minimizing heat loss during water transit, ultimately leading to significant energy savings.
