Coating and Tank Material in Water Heater

Coating and Tank Material in Water Heater is one of the most important criteria when it comes to selecting the right product. The water heater is a major electric appliance in our homes, as it is widely used. Instant hot water supply is major ease when it comes to the ageing population, young children, or regular use during harsh Winter months. But, the fact that we usually end up spending tons of money for repairs and services for our geysers is also a reality. And why is this so? Well, while there are many reasons, the inner-coating and Tank material are one of the main aspects of a good water heater. The reason is quite simple; hot water storage is one of the major aspects of an efficient water heater.

COATING AND TANK MATERIAL IN WATER HEATER

Corrosion is a major issue when dealing with a water heater’s water storage aspect. The inner surface of the metal lining of the water heater can easily get corroded or worn out, as the product has to store water within itself from anywhere ranging from a few minutes to a couple of hours. Hence, it is only obvious that the ‘coating’ of the inner surface of the water heater better be able to withstand the duration of the liquid it will be holding. This is where the coating, or rather a good quality coating, comes into the picture.

The Materials Used For The Water Heater

The top three famously used materials for the water heater are:

  • Copper
  • Stainless Steel
  • Thermoplastic is Also known as the Polymer tank.

It has been observed that Copper is a good conductor of heat and can result in a major loss of heat. Secondly, it is also quite corrosive, hence not such an excellent choice for an inner coating in a water heater.
Likewise, Stainless steel containers are also a great choice, but these require another coating to be able to survive the corrosion arising from water storage. Now let’s discuss a bit more about the other materials used for the inner coating of a water heater.

The Materials Used For Coating The Inner Surface Of The Water Heater

Now, let us take a look at some of the most prominent materials used for making the inner coating of the water heater:

  • Porcelain Enamel Glass Lined Tank
  • Glass-lined Coated Inner Tank
  • Vitreous Enamel Coated Tank
  • Blue Silicone Enamel Coated Tank

Now, let us understand in detail the meaning of some of these terms.

The polymer-coated water heater: This is one of the most preferred coating options for a good water heater. This comprises a synthetic material that can protect the stainless steel water heater from damage due to corrosion. Also, Polymer coating is great for insulation, as it minimizes heat loss during water storage.

The glass-lined coated inner tank: The glass coating is yet another great option when it comes to one of the most preferred coating liners. The process of creating a Glass coating lining is quite simple, which comprises of applying the powdered glass over the inner surface of the water heater and heating it in a furnace. This causes the glass to ‘coat’ on the inner surface, creating a fine protection layer. This process is quite simple yet effective, thus offering the kind of insulation required for the efficient working of the water heater.

The Inference: It is a no-brainer that Glass liners are a popular choice. Nevertheless, with time, the glass tends to lose out on its insulation properties, thus, leading to the heat escaping in the process. Also, some reports have declared the material to be prone to damage. So, with all aspects in consideration, the polymer-coated geyser has an added advantage over the Glass liner. Also, the Polymer coating is better in insulation and also durable when it comes to the long run with your Water heater geyser. On a side note, it is worth mentioning that thermoplastic is non-corrosive yet not a very good insulator.

Coating and Tank Material in Water Heater: The Conclusion

So, there you have it, people. These are some of the facts and features about the inner coatings of a water heater. Also, the fact that this is an essential feature when it comes to the ‘sensible’ selection of the product. Likewise, two other aspects offer a better insight into making the right choice when it comes to water heater:

  1. Be sure to locate or find out the BEE ratings on your water heater. This rating is derived from some important factors, such as good insulation properties and better material choice when it comes to the overall construction of the water heater. So, find out the ‘standing loss’ and the BEE star ratings when you are considering a couple of options. For best results, opt for a Stainless steel water heater with high BEE ratings is recommended.
  2. Warranty is the second most important aspect when it comes to considering the right water heater. This is offered by the product’s manufacturer and is usually quite important when it comes to long-lasting efficiency. Warranty is the aspect of how long the product can last and function properly without malfunctioning. In this aspect, the better the corrosive layer, the better will be the insulation; hence the better will be the ease of use. Therefore, the manufacturers will also provide long-term warranties on their products.

Some precautions when using the water heater:

  • It is important to ensure that you keep the water heater switched OFF when not in use. This is because it can lead to overheating and subsequent corrosion of the inner coating.
  • Regular servicing of the Water heater ensures its long lifespan, as any cases of malfunction can easily be dealt with at the right time.
  • Be sure to keep your space well-ventilated when and where you fix your electronic appliance.
