Electric or gas? Which is better? In reality, there is no single answer to this question. The following factors all play a role in choosing what type of tankless water heater is best for your needs:
1.Efficiency / Operating Cost: While gas tankless water heaters are certainly more efficient than their tank cousins, their efficiency usually peaks at 80-85%. Conversely, most electric tankless water heaters are 98+% efficient. electricity costs are more stable and projected to rise much slower than gas rates in future.
2.Installation: Gas tankless water heaters have complex venting and combustion air supply requirements, especially when installed in a confined space, is that these requirements can make installation very expensive. Electric tankless water heaters are very small, and they can be installed in a closet, under a sink, in a crawl space, or a wide range of other areas where a traditional tank or gas tankless cannot. the installation of an electric tankless water heater is generally much cheaper than the installation of a gas tankless water heater.
3.Maintenance, Service Life and Warranty: Electric tankless water heaters require very little maintenance. In fact, other than cleaning the inlet screen filter occasionally. On the other hand, gas tankless heaters should be inspected annually by a trained technician to ensure safe fuel combustion and performance.
4.Environmental Impact: Electric water heater is no greenhouse gas emissions, small size reduces environmental footprint in manufacturing and ultimate disposal - future electricity generation to come from green sources such as solar, wind, and wave energy, gas water heater produces greenhouse gases and increases reliance on fossil fuels

Tankless Water Heaters, are appliances that produce hot water only when called for. Unlike conventional units that keep heated water in a tank that typically holds 40 to 80 gallons, a tankless unit heats water quickly on demand. And consumes less energy because you pay to heat only what you use. Reduced energy consumption means lower utility bills. In addition, a well maintained tankless system can have a life span that’s twice as long as a conventional storage water heater.
Basically, there are two types of tankless units:
Point-of-use water heaters are small enough to fit in tight spaces, typically under the kitchen sink or other areas in the home where hot water is needed. Incorporating several point-of-use units can reduce water heating costs significantly.
Whole house units are capable of simultaneously meeting hot water requirements at several locations, such as your dishwasher and shower.
Sizing is based on the flow rate that’s required and the temperature rise that’s needed. The flow rate is the amount of water that’s needed at any one time, and the temperature rise is the difference between the temperature of the water coming into the home and the temperature of the water flowing from the faucet. If the temperature of water coming into your home is 20 degrees, and you want water that’s 60 degrees at the faucet, the rise would be 40 degrees.

The operation of an electric water heater is essentially the similar as that of a gas heater. It heats the cold water inside the pipe using the electric heating elements after bringing it in through the dip tube. Through the heat-out pipe, hot water rises in the tank and is transported throughout the house or shower .
It with two pipes— one for cold water inlet and the other for hot water outlet— makes up the geyser. It is equipped with thermostat-controlled heating components. Water is not heated above a predetermined temperature value by the thermostats. Typically, a metal casing is used to enclose the tank, which is then covered with an insulating material.
Jnod electric geyser is the tankless ,which is no need to pre-heat the water. The hot water can be come out instantly. It has temperature constant function,the temperature difference is only ±1 degree Celsius. Very comfortable and convenient .
JNOD instant electric water heater is hot water on demand. Hot water has become a necessity today and having access to hot water at one go can be a relief. In this time and age where everything is done instantly, people will not expect to wait several minutes for manually heating the water. So, JNOD instant electric water heaters are a necessity. We walk through 5 reasons on why should choose JNOD instant water heater.
They last longer .
JNOD tankless electric water heaters are built to last longer. Traditional water tanks have a lifespan between 8 to 12 years. However, an instant water heater usually has a warranty of 10 to 15 years and can go on for two decades if maintained properly. When you decide to switch to a tankless water heater, you automatically double the lifespan of your heating system.
Convenient and efficient.
JNOD Instant water heaters have no storage tanks and provide hot water on demand. Also, these water heaters are about 1/5 of the size of traditional water tanks which makes them convenient to fit into smallest of places. Tankless systems are typically mounted on the wall, allowing you to save your home’s floor space. Another advantage is that you can install instant water heaters in more areas of your house and enjoy its benefits.
Saves money and energy.
Although you may have to pay more for a tankless hot water system compared to a traditional water tank, you save a lot by running tankless over a lifetime. First, the tank-free system is designed to last twice as long as a heating system. This makes it a wise financial decision in the first place. Also, you don’t have to pay more for heating water when it is not being used. When you turn the tap on, the water passes through the tankless heater and delivers an ample number of liters per minute to you. Around 30 percent to 50 percent of energy can be saved switching over to an instant water heater.
The water is fresh and clean.
Water from a traditional water tank tends to pick up bits of rust and sediments that build up with the tank. JNOD instant hot water system has no tank and stores no water within which makes the water cleaner and freshen in comparison. Also, instant water heater systems have no bacterial growth issue compared to heaters with a tank.
A Constant Supply of Hot Water.
Traditional water storage tank heaters can heat only a certain number of liters at once. While traditional heaters do keep an ample supply of hot water on hand, it is not a consistent supply. There might be plenty of water available during the day, but as the day passes and more people take a shower, within no time you run into trouble. With JNOD instant electric water heaters, water keeps flowing for as long as you need it. No matter how many family members take a shower, you won’t be running out of water for sure.

When it comes to tankless electric water heater, one of the biggest mistakes is buying a unit that is too weak to satisfy whole house hot water needs.
You don’t want one that is too small to supply whole house hot water needs, nor too big that power cord could not support the amperage when the instant electric water heater works.
The power of tankless water heater should be as appropriate to your household hot water needs as possible.
How many kW for JNOD tankless electric water heater?
To properly answer which power do you need, you have to figure out below points beforehand:
1. How’s the temperature of inlet water at coldest time?
2. How many degrees could the certain heater heat up at how much water per minute?
Example:
If inlet water flow has 2L/min, max temperature rise of a 5kW model could be up to max. 35℃, But in the relatively cold area, winter time the coldest water temperature is 0℃, plus 35℃, it could only reach 35℃, even it works with full power, there still not hot enough for shower use.
But for the warmer area, in winter, inlet water still have 12℃, then total it could heat up to 47℃, it was quite good enough for your shower use.
In JNOD, we have a professional team to help you choose models with a most suitable power, no matter for single shower use or multiple points use, we will help to fulfill your different hot water requirement!
