Traditional hot water heaters can’t keep up with today’s appliances.
Newer solutions on the market, including tankless water heaters, change the way your water is heated.
When you turn on the tap, water flows through the unit and is heated before it reaches the faucet.
There is no storing, no useless heating and definitely no wasted energy on keeping the water at a set temperature even when you don’t use it.
Below are some tips on how to choose the best tankless water heater for your home
If your house is smaller or you don’t regularly use a lot of hot water, buy just one tankless heater for your entire home.
But if you do use a lot of hot water, you can also connect multiple units for whole-house water heating.
Did you know that tankless water heaters are available in both gas and electric?
Make sure to choose the one that is most efficient for your home and your wallet.
Unlike regular water heaters, tankless heaters are sized by the number of gallons of hot water they produce per minute (GPM), not their size.
It is recommended you make a rough list of how much water you use, and whether these usages collide with one another.
For example, you can use the rule-of-thumb sizing to do the estimation on your own.
Here are some rough estimations commonly used:
· 1 bathroom or 1-2 people requires 140,000 BTUs
· 2 bathrooms or 2-3 people requires 190,000 BTUs
· 3 bathrooms or 3-5 people requires 380,000 BTUs
Nevertheless, it is still best that you consult a professional plumber to make sure your tankless water heater is the right size for your home.
Even do-it-yourselfers need to call on a professional sometimes, especially to install a tankless water heater.
This way you are completely confident your system is installed efficiently, effectively and correctly.
Additionally, you can ask for advice on how to suit this system according to your individual requirements.
You can maximize the potential of your heating system by insulating all of your exposed pipes.
This will make your water output produce 2 to 4 degrees warmer when it comes out of your faucet as well as protect your home’s pipes from freezing in the winter.
Tankless water heaters are becoming more widespread and the right choice for more people and more properties now. Compared to tank water heaters, tankless water heaters have a longer lifespan, lower operating costs, and a number of other benefits. But how do you know if a tankless water heater is right for you – and if it’s worth the investment?
1. Your Old Water Heater Is Wearing Out
As a water heater gets older, it becomes less efficient. The heating elements and other parts of the heater can get clogged with grime and corrosion, leading to higher heating costs, and poor performance. If your old water heater is wearing out, you may want to consider foregoing the traditional, tank-based water heater in favor of a tankless model. Because you’ll be purchasing a new unit anyway, this is the perfect time to make the switch!
2. You Want To Lower Your Monthly Energy Bill
Instant hot water is delivered on-demand which nearly eliminates standby heat loss. Water flows through an advanced system of electric heating elements, which instantly heat it up the desired temperature. There is no need for the storage of hot water – which boost efficiency dramatically. Tank water heaters hold the water within a tank where it is heated and re-heated until needed. According to the US Department of Energy, a tankless water heater uses up to 34% less power to heat water. Moreover, based on the same study, electric tankless heaters bring in savings of about $44 per year.
3. You Constantly Run Out Of Hot Water
Tankless hot water heaters are rated to provide a certain number of gallons per minute (GPM) – this is the rate at which the heater can constantly heat and deliver hot water to appliances and faucets throughout your home. he chart below shows the range of water usage range and average water temperatures for various fixtures. We suggest using 2.5 gpm for a shower and 1.0 gpm for a bathroom as a reference point in determining your total simultaneous water needs.

Yes, but a tankless water heater does more than save you money.
Savings: Space
Since tankless water heaters do not have tanks, they take up less space. You don’t need to have a utility room or area in the garage for your water heater. Your tankless water heater can be stored in a closet or under the sink. Extra space is valuable these days, especially if you’re living in a smaller home or condo.
Savings: Energy
Traditional water heaters hold around 30-50 gallons of water and keep it heated until you’re ready to use it. Depending on the size of your family and the amount of water your family uses, this could be costly. (Did you know that water heater energy usage is the second-highest source of energy use in the average home?) Tankless water heaters don’t hold water, so they heat the water as it comes in—no constant energy to keep 15 milk jugs’ worth of water hot.
Savings: Time
Tankless water heaters save you time in the morning because the water is heated as it comes through until you are finished. While a traditional tank does have hot water on demand, that’s only until the tank runs out. Then you have to wait for the tank to refill and warm up the water. Tankless heaters don’t have that lag time because there’s unending water flow from the tank to the tap.
Savings: Money
Most new homes have a traditional water heater already installed when you move in. If you’re looking to replace the traditional tank, however, there is some work required. While installing a tankless heater might present a higher price tag than expected, the overall financial gains will overcome that deficit. It will raise the initial investment, but it’s an investment worth looking into for your home and your family. When comparing the overall savings of space, energy, time, and money – the savings really can add up.
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.

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.

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.
