Closed System Flushing - Echo Square Services

What is Closed System Flushing?

Closed-system flushing of hot water and chilled water systems is a vital step in the installation and commissioning process of these systems.

It is necessary to ensure that the systems are clean, efficient, and free of any contaminants that could potentially damage the system or compromise the quality of the hot water or chilled water being provided.

Here are several reasons why
closed-system flushing is important:

Removing Contaminants

During the construction process, it is common for debris and contaminants to find their way into the hot water and chilled water systems. This could include dust, dirt, sand, and even small tools or materials that were left behind. If these contaminants are not removed, they can clog up the system and reduce its efficiency. Pre-commission cleaning helps to remove these contaminants and ensure that the system is clean and ready for operation.

Improving system efficiency

When a hot water or chilled water system is clogged with contaminants, it has to work harder to provide the desired level of hot water or chilled water. This can result in higher energy costs and a shorter lifespan for the system. Closed system flushing helps to improve the efficiency of the system by removing any obstructions that could hinder its performance.

Quality of hot or chilled water

Contaminants in the system can also affect the quality of the hot water or chilled water being provided. For example, if a chilled water system is contaminated with dirt or debris, it can cause the water to become dirty and potentially lead to the growth of bacteria or other microorganisms. This can compromise the quality of the chilled water being provided and potentially pose a health risk. Closed system flushing helps to ensure that the hot water or chilled water being provided is of the highest quality.

Protecting the system from damage

Contaminants in the system can also cause physical damage to the system. For example, dirt and debris can wear down pumps and other mechanical components, leading to costly repairs or replacements. Pre-commission cleaning helps to protect the system from this type of damage.

Closed System Flushing &
Cleaning Methods

There are several methods that can be used for closed-system flushing of hot water and chilled water systems. Some common methods include:

Chemical cleaning

This method uses chemicals to dissolve and remove contaminants from the system. Most of these chemicals are biodegradable and environmentally safe.

Mechanical cleaning

This method involves using automated means, such as brushes or scouring pads, to remove contaminants from the system physically.

High-pressure water jetting

This method involves using a high-pressure water jet to blast away contaminants from the system

Types Of Chemicals Required For Closed System Flushing

There are several types of chemicals that can be used during the pre-commission cleaning of heating and chilled water systems.

The specific type of chemical that is used will depend on the type of contaminants present in the system and the desired cleaning method. Some common chemicals used for pre-commission cleaning include:

Alkaline cleaners: These are strong basic cleaners that are effective at removing grease, oil, and other organic contaminants from the system. These tools effectively clean the inside of pipes, boilers, and heat exchangers.
Acid cleaners: These are strong acidic cleaners that are effective at removing scale, rust, and other inorganic contaminants from the system. These tools effectively clean the inside of pipes, boilers, and heat exchangers.
Solvent cleaners: These are chemical cleaners that are effective at removing a wide range of contaminants, including grease, oil, dirt, and wax. These tools effectively clean the inside of pipes, boilers, and heat exchangers.
Biodegradable cleaners: These tools use environmentally friendly cleaners made from natural ingredients, making them safe for use in heating and chilled water systems. Not only are they effective at removing a wide range of contaminants, but they are also significantly less harmful to the environment compared to traditional chemical cleaners. As a result, they offer a safer and more sustainable cleaning solution.

Additional Guidance

Regardless of which method you choose, it’s essential to follow proper safety protocols during pre-commission cleaning. To begin with, always wear the appropriate personal protective equipment (PPE). In addition, handle and dispose of all chemicals according to safety guidelines. Furthermore, ensure the system is fully purged and drained before you start any work. By taking these steps, you help maintain a safe working environment and protect the integrity of the system.

In addition to pre-commission cleaning, it is also important to flush the hot water and chilled water systems prior to commissioning. This process involves running clean water through the system to remove any remaining contaminants and ensure that the system is fully operational.

Pre-commission cleaning and flushing of hot and chilled water systems plays a vital role in the installation and commissioning process. It ensures the systems stay clean, efficient, and free from contaminants that could cause damage or reduce water quality. By following safety protocols and using the right cleaning and flushing methods, you actively protect your systems and maintain their performance for years to come.

We manage a large residential block and recently reached out to Echo to quote to reline two water tanks that were failing. An absolute fantastic service all round. A quote was received within a day or so. Works were booked in and communication was excellent. We were really impressed with the engineers on the day. They communicated well on the day in terms of the plan of action. Once the work was complete, they ensured all areas were left clean and tidy. A follow up report post works was sent very soon after the works.

We look forward to working with Echo again. If you need honest, reliable contractors who will get the job done and to a high a standard, don't hesitate to get in touch with them.

Thank you.

I contacted Echo Square on behalf of a client of mine who urgently needed her Victorian underground Cistern re lined. The work was quoted for promptly and the work carried out to a high standard by the engineers who were courteous and friendly despite their long drive to site. My client was very impressed and so grateful to have her Cistern back in working order. I would highly recommend this company and will most definitely approach them again should I have another client with tank issues in the future. 5 star service!

We were carrying out plumbing works on a site in London where we discovered a badly leaking GRP water tank, the Echo Square Services team attended site as quickly as possible to repair the leak and reline the tank. We will definitely contact them next time we are faced with a similar issue - would highly recommend.

Having used other companies in the past I can wholeheartedly say that our dealings with Nationwide Tank Relining have been a breath of fresh air. We have had tanks relined, water hygiene assessments and floor coatings. All work was carried out in a timely manner and the quality of work has each and every time been exemplary. My bosses are thrilled with my decision to switch to Nationwide Tank Relining and a tank that was relined 10 years ago by them still looks good as new internally, and the money we've saved from choosing the right supplier has proven to be a very smart business move. Highly recommended!
