Are you looking for the best electric tankless water heater then you are at the right place

From washing hands to washing dishes to bathing, hot water is an essential requirement in our daily lives. Especially after a pandemic, it has become very important to use warm water to ensure proper health and safety and a tankless water heater would serve the purpose. 

Based on energy, water heaters are divided into three categories-natural gas, electricity, and solar energy. Below, for your knowledge, we mentioned the detailed description of each category.

Electric Tankless Water Heaters :

Such tankless water heaters consume energy to provide hot water, as the name suggests. The working theory of electric geysers is very simple: electrical energy is converted to heat by heating elements to boost the temperature. 

Any tankless water heater which is electric is much better than a gas tankless water heater.

Any of these devices on the market come with intelligent features such as time delay, the temperature of demand, and automation.

These tankless water heaters are very suitable for people living in apartments and rented houses. Compared with gas tankless water heaters, electric water heaters can heat higher temperature water.

Gas Water Heaters

These water heaters to operate consume natural gas like LPG – Liquid Petroleum Gas or propane. Compared to electric water heaters, the gas water heaters can quickly heat the water. When installing a gas water heater, it is important to fix the equipment behind the LPG cylinder to provide a complete gas supply through the pipeline.

Solar powered water heaters

With this type of water heaters, you don’t need to waste money on electricity or gas, it can easily provide water for the whole family. The initial expenditure is marginally higher than other alternatives especially the tankless water heaters. It will, however, pay off in the long run. For apartments and residents, these heaters are not necessary.




As far as your knowledge is concerned, we include the same “buying guide”. In addition, after careful analysis of quality, durability and service, we also selected the best electric heater.

Buying Guide for Water Heaters:

 

The following factors need to be considered to help you determine the best tankless electric water heater for your home:

 

Size or capacity:

This factor relies upon the use, number of individuals in the house, reason and others. For example, in the event that you have a huge family, at that point buying a tankless water heater with higher capacity or giving heated water rapidly to a longer period is suggested. But, in case you are a small family or only an individual, then it is smarter to put resources into a small sized tankless water heater.

 

Material of the water tank:

Usually, water tank heaters are made from either copper, thermoplastic, or stainless steel.All materials ensure efficiency and safe output.

Copper:  Copper is a widely used material to build tanks for the water heater. Because of the copper, you get a quick response in heating the water, as copper is a good conductor of heat. However, a copper tank water heater can have corrosion, loss of heat, and would require regular maintenance.

Stainless steel: Usually used in most modern water heaters, stainless steel water tanks are usually coated with anti-corrosion powder and glass lining to prevent corrosion of the water tank and other electrochemical reactions. The insulation is better and almost no maintenance is required. 

Thermoplastic: A little-known material used in storage tanks. However, compared with copper, thermoplastic storage tanks have better corrosion resistance. The downside is that they are not insulated.

 

Anti-Scale And Anti Corrosive:

When buying a water heater, it is important to check whether the water tank has an anti-corrosion and anti-scale lining. However, before that, please analyze whether your water is hard or soft. In some areas of India, the water quality is extremely poor. Hard water corrodes easily and accumulates calcium scale in the water tank, which can impair heating efficiency. And you may have to replace the water heater once a year.

In order to solve the corrosion problem, the manufacturer coated the inside of the water heater tank with anti-corrosion materials. Some of them include  porcelain enamel glass, glass lined, vitreous enamel, blue silicone enamel, titanium etc.

Steel-based alloy and glass coating can provide good insulation, reduce corrosion, and can maintain the original surface for a long time. Put the magnesium rod in the middle to keep the corrosive salt barrier. To prevent damage, you can use a water softener-to convert hard water into soft water.

 

Insulation:

In order to reduce energy consumption, the geyser is wrapped in an insulating layer. In addition, insulation can speed up the heating process and maintain operating temperature. The thicker the insulating layer, the less heat loss. Geysers appearing on the market have different insulation ratings. However, in order to obtain more effective results, you can also add more additional insulation layers outside the heater.

The most commonly used insulation material for geysers is fiber glass wool, which is fixed with a belt or trap. When using the burner, the insulation material should prevent the outflow and airflow of the combustion gas. Some modern geysers have PUF (polyurethane foam). They are much better than glass wool because of its ability to maintain water temperature for a long time. This not only saves 40% of energy, but also saves money
