Case Study 1:

CUSTOMER: Mr. B. Melville

LOCATION: Amble, Northumberland

HEATING SYSTEM: Baxi fire back boiler with cylinder

PROBLEMS: System very old and inefficient slow to heat and recover particularly domestic hot water

SOLUTION. Install Vortex.
Mr Melville reported that his system was an old Baxi fire back boiler which was noisy and very inefficient. He was considering a combi but spoke to me about the fitting of Vortex.

Mr Melville fitted Vortex and reported that the improvement to his system was apparent within minutes of turning it on.

Noise levels were greatly reduced and the pump was much quieter. Radiators heat up much faster.

After standing overnight the domestic hot water was still hot. Mr. Melville knows that the hot water heats to a higher temperature which is the reason for this.

He is confident that his gas bills will be much lower.

Effects of corrosion

Effects of corrosion & how to prevent corrosion

Corrosion of most materials is inevitable. It is the result of these materials being in an unstable state in their environment. The deterioration caused can have an immense effect on our lives. From economic to health and safety issues, corrosion has had deep implications on the way we live. With the advances in technology, it has become quite important to take steps to prevent corrosion. The effects of corrosion are plenty. Let us take a look at some of them:

Economic effects

Corrosion can prove to be a headache for businesses and governments. Every year, they incur huge losses because of corrosion. Some countries have even attempted to determine the costs of corrosion and the numbers are staggering. Corrosion has also affected large corporations in their operations. Some companies take effective measures, like using excellent materials and constantly modifying their equipment to prevent corrosion which has obviously improved their growth and productivity.

Health effects

Modern day advances have brought about revolutionary changes in our health systems. Metal prosthetic devices such as pacemakers, hip joints and other implants have made a lot of previously impossible feats possible. But the problem of corrosion has caused many limitations. Corrosion causes inflammation of some products around implants and sometimes, even fracture of weight-bearing prosthetic devices. The good news is that these prosthetic devices are constantly improving. Preventing corrosion in these devices and other medical equipment will surely improve health conditions drastically.

Safety effects

Structures that cannot sustain their environment can prove to be very dangerous. It can cause serious injuries and even loss of life. Corrosion endangers the safety of our modern day structures like aircrafts, bridges, automobile, pipelines and so on. One defective aircraft or a collapsing bridge can have serious consequences on so many lives. Governments and responsible authorities must make sure that the effects of corrosion are minimised to ensure safety of citizens by taking effective corrosion prevention measures.

Technological effects

Corrosion has considerably hindered many advances in technology. Quite a few advances require materials to withstand high temperatures and highly corrosive environments. The drilling for oil in sea and land have also been deterred due to problems caused by corrosion which has hampered our progress in the energy sectors. But at the same time, certain measures have been taken to reduce the effects of corrosion. Over time, the technological effects of corrosion will surely be curtailed.



Cultural effects

Corrosion has had its share in deteriorating the precious artefacts of our ancestors. The modern day pollution in the environment has also not helped. Preserving the beautiful creations of our past has always been important to humans. Several museums around the world have hired special professionals to protect these treasures of our past from corrosion. These artistic relics of our past have immense value to our identity and should surely be preserved from deterioration through corrosion.

These effects illustrate the huge impact, corrosion has on our daily lives. Preventive measures against corrosion must be applied and implemented. The recent advances have brought some good ways to prevent corrosion.

How to prevent corrosion of Steel

Prevent Corrosion of steel

With the exception of gold, platinum and a few other metals, corrosion affects almost all metals. It is the deterioration of metals by chemical reactions in the environment. Iron and steel are the most commonly used metals, but at the same time, are quite susceptible to corrosion. Every year, we incur huge amounts of losses due to corrosion of iron and steel. It damages building structures, bridges, water systems, home appliance systems and other important industrial equipment causing huge economic burdens. If the correct preventive measures are taken ahead of time, a lot of trouble caused by corrosion can be minimised. Let us see how iron and steel corrode or rust and what can be done to prevent corrosion.

Corrosion of steel

Corrosion of steel is inevitable. The most significant category of steel corrosion is the rusting of iron, which is a chemical process that weakens iron over a period of time. Rust is the red crest on top of the metals that we see. It is not just moisture that makes iron rust. Both water and oxygen are necessary for the steel to corrode. A great example is shipwrecks. When the ship sinks deep into the ocean, it stops rusting. The lack of oxygen in such depths of water is what makes the rusting stop.

The rust on top of the steel is actually protecting it from further corrosion. But when iron rusts, we clear it away, exposing this iron to further deterioration. Corrosion of steel is a chemical phenomenon that can be hindered. Some strategies have been developed to get hold of this immense problem.

Preventing steel corrosion

The most effective method of preventing corrosion in steel is to coat it with another material that does not rust. Over the years, advances in metallurgy have enabled us to mix different alloys and get the desired results.These procedures have saved us lots of trouble and costs.Here are some ways to prevent corrosion in steel:

Zinc Coating (Galvanised steel)

Galvanisation is the process in which zinc coating is applied to steel to prevent it from rusting. When zinc is exposed to oxygen in the environment, zinc oxide is formed. The zinc oxide further reacts with hydrogen to form zinc hydroxide. Finally, this zinc hydroxide and carbon dioxide create a thin layer of zinc carbonate, which prevents steel from rusting. This process is preferred because it is quite reasonable and cost-friendly.

Chromium Coating (Stainless steel)

Chromium is another substance that does not rust. The chromium reacts with oxygen to produce chromium oxide. This chromium oxide creates a thin protection layer which is also the strongest. Stainless steel has been widely manufactured and is the most robust steel.

Aluminium Coating (Aluminium steel)

Aluminium steel is coated with aluminium-silicon alloy that is quite resistant to rusting. It keeps steel’s properties at very high temperatures and is often used in ovens, heaters and fireplaces. Aluminium coating is one of the most effective strategies to prevent corrosion in steel.

Prevent Corrosion in a heating system

Prevent Corrosion in heating systems

A typical heating system contains various metallic elements like steel, copper, aluminium, iron etc. which are prone to corrosion. Corrosion is natural in heating systems and can cause problems. Corrosion of these metals determines the lifespan of your heating system and therefore knowing how these materials are vulnerable is important to prevent corrosion in your heating system. Let us take a look at how these different metals corrode and strategies to prevent  corrosion:


Copper is quite easily corroded. When it corrodes,  tiny amounts of copper dissolve in water, which lead to the corrosion of other metals in the system. Its corrosion can cause equipment failure. When it is brought into contact with aerated water, it only corrodes slightly. The problems occur when the corrosion goes beyond this. Continued copper corrosion can cause green stains. It is quite necessary to prevent corrosion of copper if you want to increase the life of your heating system.


Aluminium is also a very important metal in the heating systems. Its corrosion also has to be avoided at all costs. It is quite inexpensive and therefore is used in a lot of heating systems including boilers and radiators. It has a protective film of surface oxide, which is its shield against corrosion. But destruction of this shield by harmful contaminants can cause corrosion. Not only harmful contaminants, this shield is also vulnerable to changes in the pH value of the water. For aluminium to minimise corrosion, the pH value of water must be levelled between 6.5 and 8.5. Its corrosion occurs in small localised areas which form pits on the metal surface. For your heating system to work properly, corrosion of aluminium has to be taken into account.


Steel is an essential component of your heating system. It is easily corroded in the presence of oxygen and water. An iron oxide debris is formed which is splinted into the system water and this deteriorates valves and other moving parts. As a result, a localised corrosion occurs that leads to equipment failure.

Stainless steel is an alloy that has a protective oxide layer that prevents it from corrosion. However, aggressive contaminants can penetrate its layers too.

Protecting your heating systems

Being vulnerable to corrosion, heating systems can easily malfunction if proper care is not taken. Here are some steps that you can take to prevent corrosion in your heating systems:

  • Make sure that regular maintenance of your heating system is carried out. It is quite helpful in reducing contamination issues such as flux residues. Giving proper care to your system, you can easily prevent corrosion and improve the life of your heating system.
  • In addition to proper maintenance and cleaning of your heating system, you can also use some effective corrosion inhibitor. Using corrosion inhibitor can decrease the rate of corrosion in your heating system.
  • The inhibitor has to be used in accordance with the appropriate dose. This will ensure the proper functioning of your heating system.

Cause of Corrosion

Corrosion caused by oxygen – Preven Corrosion

Corrosion has always been an inhibiting factor in advanced building materials and structures. It has caused us great trouble in modern industries ranging from automotive to construction. Oxygen Attack or corrosion caused by oxygen is a serious concern for your heating appliances. Let us take a look at what it is and how to delay or even prevent corrosion caused by oxygen:

What it is?

An oxygen attack is an electrochemical process which enables the temperature to rise so much with additional energy that chemical reactions are accelerated on metal surfaces.This results in quite quick and severe corrosion. Dissolved oxygen in water is the key catalyst and potentially dangerous for your heating appliances.

Oxygen attacks inside the boilers

The metal surface of your boiler system is always vulnerable to oxygen attack. It is the most common source of corrosion inside your boiler system. As the temperature rises, so does the chances of oxygen attack in the boiler system. The three factors that lead to oxygen attack in the boiler system are: Presence of moisture,presence of dissolved oxygen and unguarded metal surface.

Dissolved oxygen forms certain localised corrosion areas known as pits. These oxygen pits cause the metals to fatigue and fail. When the boiler’s internal surface is heated, the dissolved oxygen in feed water can become very aggressive and forms these pits on metal surface. Oxygen attack can lead to failure of critical parts of the boiler system such as steam drums, mud dams, boiler headers and so on. Not only does oxygen corrode the boiler system, it also dissolves the iron surface which impairs the metal site. Henceforth, dissolved iron reaches inside the boiler and causes dysfunctions such as overheating and tube failure. Corrosion caused by oxygen can be in a localised region or it can impair the whole functioning of the boiler system.

Ways to prevent corrosion caused by oxygen

Oxygen attack has been a severe threat to your boiling and heating systems. Here are some ways to prevent it:

Controlling oxygen

The amount of oxygen in the boiler feed water is reduced by heating it to reduce its solubility. Furthermore, a Deaerator is used that removes most of the oxygen from the system. Still, small traces of oxygen remain that may cause corrosion. Oxygen scavengers may be added to feed water to further reduce the amount of oxygen. This method has been quite efficient and is used widely.

Coating the metal

Organic and inorganic coatings have been used to protect equipment, dealing with oil and gas to prevent corrosion. Asphalt enamel, sacrificial coating, nickel coating, etc. can be used to protect the metal surface from moisture thereby, protecting it from oxygen attack.

Interrupting the corrosion process chemically

Neutralising inhibitors such as amine, ammonia and so on can be used to hinder the oxygen attack. These inhibitors will absorb themselves to the metal surface and act as barriers for the harmful corrosive elements. The chemical layer has been proven to be quite thick and effective in keeping corrosion at bay.
