Step 1: The first step should be to remove the pre-installed water heater. Cut off the water supply, power supply and gas valves to the old water heater. Drain it if any water is still in the tank.

Step 2: The next step involves the installation of the new gas supply setup. The tools and the accessories required to setup the gas line will be provided in the installation kit itself.

Generally, the tankless water heater works on the principle of exchanging the latent heat. First, the gas is being provided for combustion to the burner installed in the heater. In the same instance, the cold water valve provides cold water to heat up in the combustion unit. The gas ignites the burners, and the water is being heated present into the two heat exchanger units by exchanging latent heat. The water is preheated as it passes through the heat exchanger. The heat exchanger units are made up of stainless steel. All the extra heat produced during this process is being stored in the vent system of the heater. The extra heat is stored efficiently before it escapes. The water is continuously heated up as it passes through the heat exchanging units. Finally, the water is being excited by the outlet pipe. 

The hot water is travelled through the pipes and can be utilized anywhere required via a water fixture. The heater itself will control the flame inside the heating unit of the tankless water heater. It will adjust the flame by the gas provision from the gas supply unit. As soon as the water fixture is closed, the gas supply and the cold water inlets will be closed as well. Do not change the standard-setting in the heater as per given in the manual. The setting of the temperature of the water will differ by the usage of the water. The temperature of the water, which will be used in the kitchen, will be different as the water that will be used in the bathroom or in shower.

The circulation of the water in the heater will differ from the brand as well as their model. In most of the water heater, the water and the gas flow is being adjusted by the owner or the user. Some of the heaters in the market has the recirculation technology installed in the product. The water will be heated more as per the requirement of the user by recirculating the water again from the heat exchange unit. 

The size of the Tankless water heater will vary as per the usage. The ideal size of the tankless water heater will be around 30 inches x 20 inches wide. Several water heaters are available in the market, which comes in various sizes and differing in the capacities as well as technologies. There are several factors to determine the proper size of the tankless water heater, such as the mounting space, the temperature of the cold water used by the heater, the rate at which the water will be flown in the heater, and many more.

Going for a water heater, without knowing the features that are the most important and a must for a user to know, will always be just wrong. Henceforth we have curated a list of the most important features that everyone should look into while buying a water heater.

The warranty of the product is one of the prime features to look for while you buy a tankless water heater. Usually, the range of the year for warranties are 3 to 12 years for the available products in the market. Naturally, when you buy the water heater with the more extended warranty period, it will come with the more efficient elements inbuilt in it. Such as burners speed, thickness of insulation material for eliminating the loss of heat, and more. Always go for the electric tankless water heater with the longer warranty period, since it comes with the additional features which will enhance the durability and working of the product.

The digital display will help you in monitoring many elements such as the temperature of the heating exchanging unit, timer, pressure in the heating unit, and so on. It will always indicate whether the heater is on or off. It will also display the amount of gas remaining in the gas supply unit. It makes the working and maintenance of the heater more easy as it will also indicate the indicator when it needs any maintenance. The user can monitor a couple of activities of the tankless water heater. Always check the availability of the digital display inbuilt in the product while buying one.

The valves are the critical part of setting up the tankless water heater. There are several products which already comes with the brass valves and some with plastic valves. The brass valves are the excellent conductor for the heat; on the other hand, the plastic valves are a better insulator to the weather. But the sturdiness of the brass valves are much better than the plastic valves. So it is quite difficult to decide whether to go with the plastic valves or brass ones. Go for the plastic valves, but check the durability of the valves before buying.

Many water heater comes with the recirculation heating technology inbuilt in it. This technology is for water heating more efficiently. Always check for the feature of recirculation technology in the tankless water heater while you buy one.

As we have reviewed the top 10 best tankless water heater systems, let’s take a glimpse of some of the most crucial features which everyone should know about before purchasing a water heater.

Energy efficiency is a term that has taken the whole appliance realm by storm since there have been talks to encourage more people to purchase efficient and renewable energy appliances.

Try seeking out for models that offer high-efficiency rates. Also, several models operate without a storage tank since electricity is used only when the warm water is being released from the sink, therefore, enabling consumers not to pay for more than they usually use.

Some tankless electric water heaters assure quick warm water. But not all of them can provide so soon. That is why we recommend looking for models that have inbuilt thermo optical sensors. They are being built to provide warm water when necessary. Moreover, as stated by Energy Saver, water heating comprises around 18 to 20 percent of the entire utility expense.

Since storage water heaters have an empty tank during the day, it starts accumulating stagnant water. This will make it prone to bacteria buildup from both inside and outside areas. It is thus leaving the members in the household at dangerous risk. Also, some of these dangers include Legionella bacterial growth, which happens to grow in motionless, warm water.

This is why we suggest opting for an electric tankless hot water heater. Because it does not make use of a tank. Therefore, eliminating the chance of water sitting still in the system and further eradicating the potential growth of bacteria. Water flows directly from the pump, transfers through the system and pipes, and finally is released at the faucet.

Well, depending on the amount of hot water, you tend to make use of and which method you use to heat the water, i.e. electric or gas, you will obtain a host of options. There are a few types that have declared to reduce energy expenses up to a half than the standard storage models. However, their extra up-front costs would indicate a higher payback period. We’llWe’ll be looking into 2 types of water heaters and move onto tankless heater units due to their on-demand usage.

These tanks are the most customary and commonly used in the world of water heaters. As it name indicates, these include an insulated tank of which the water is heated and conserved till use. If needed, the water stored will be released from a pipe onto the top area of the water heater.

In addition, it comprises of a pressure-relief and a temperature valve. It opens if the temperature or pressure levels exceed the pre-defined level. Typically, water heaters that make use of natural gas utilize less energy. Also, they cost way less to operate (by about half) than compared to electric water heaters. Although it is essential to note that the gas models are far more expensive during the time of purchase.

These units don’t store water. However, they deploy heating coils, which heats the water according to your needs. Also, they happen to be more efficient when it comes to using energy comparatively than a storage tank. But only offer restricted levels of hot water, which flows around 3.5 gallons per minute (which widely depends on inlet water temperatures). These units are ideal for those who are generally not drawing adequate water for more than a single-use, such as operating both a dishwasher and a shower at the same time.

Tankless heater models are perfect for households that employ natural gas to heat the water. Although, electric models might need a costly upgrade and are not compatible with the usual capacity of a home’s electrical system.
