Best Immersion Rod Water Heater Buying Guide

Immersion Water Heater - Buying Guide

Factors To Consider Before Buying The Best Immersion Rod

A. Heater sheath material

It matters what sheath material or coating the machine you are investing in has because this determines the amount of heat given off. Usually, it is made of copper with a nickel plating that is usually anti-corrosive or rustproof. What happens is that when you use your machine for a prolonged amount of time, being in constant contact with air and water makes it prone to rusting, and that’s where the heater sheath material comes into play to prevent such corroding, which potentially reduces the longevity of the machine. Therefore, it is very important to find out the material and do proper research and find the best immersion rod that can either takes a long time to rust or regarding whether it can take such a huge preventive measure against rust. 

B. Power density 

The power density of a water immersion heater rod usually ranges from between 1000W to 1500W, and this determines how fast your water will get heated up. The lower the Watt, the longer it will take for you to get the water ready. Usually, a 1500W immersion water heater gets the job done in less than 15 minutes and is super fast in operation, but anything less than that could range from 15 to 30 minutes to get the simple job done. It also reduces energy consumption if the power density is lower than average.

C. Price 

Usually, even the best immersion rods are much cheaper than geysers, and indoor plumbing clubbed together. The price of an immersion heater could range from Rs 500 to Rs 2000, depending on the different types of options that are available: namely power density, the material used, temperature controller, good quality build, to name a few. However, the branded high-quality products are the ones that are more long-lasting and also the most productive and prevent any shocks or leaks to provide a superior experience.

D. Warranty 

The water heaters usually are sold with a warranty which may range from 1 to 2 years, depending on the brand you’re getting it from. The more the price, the more years of a warranty you will get. However, it is recommended that you buy a product that is easily serviceable because some of the companies have terrible service centres, which will make your experience a bitter one. 

How Do Immersion Water Heaters Work?

Immersion water heater rods, like all heaters like gas geysers, have a certain scientific theory that works to make the water hot for your use. The immersion water heater is a heating element that is submerged in the water, and when it is switched on, an electrical current passes through the head of the rod, which heats the water which is in contact with it. After a certain period, your water in the bucket is heated up. 

If your immersion water heater has a temperature setter, it is an in-built thermostat that keeps the temperature at a stable degree so that it is according to the need or convenience of the user. All you need to do is carefully submerge the heater in the bucket of water, switch it on, and then switch it off when you think it is done and pull the machine out of the bucket with the provided clip. It is recommended never to put your fingers or hand inside the bucket while your machine is on. 


As curated above in reviews and the buying guide, an immersion water heater is an extremely useful device to have as a backup in case you don’t have the resources to plant a geyser in your bathroom or don’t have the right plumbing to make it work. It is extremely user friendly and consumes much less energy, and easily portable and lightweight in most cases, which makes it a very popular device to have in your home for the perfectly warm water bath to lift your mood and rejuvenate after a tiring day or on a cold winter morning when you don’t feel like touching cold water. It is recommended that you invest in a high-quality immersion heater that fits your lifestyle and specific needs.
