Electric Water Heater manufacturer- China Suppliers Manufacturers Factory

When buying a tankless water heater, most people don’t know what size tankless water heater they need.

If you are looking to install tankless electric water heater and you’re unsure of which size you should buy, here are some factors you should take into account:

- The size of your house

- Flow Rate (GPM): How much hot water you will need at any given time

- Temperature Rise (ΔT): The difference between the incoming cold water temperature and the desired temperature

Your Household Size

If water heater is too small, it will result in it not being able to produce enough hot water for your household demand. For example, you might not be able to run more than one shower at a time, especially in the freezing winter.

On the other hand, water heater is too large, it will end up being more costly than necessary, since you will be paying more upfront for the larger size (although it could be useful if you plan to upsize your home later).

Hence, to work properly, a tankless water heater needs to be just the right size to meet your home's hot water demand.

Rate of Water Flow

Tankless water heaters are often referred to as demand water heaters. On-demand refers to having continuous hot water output for as long as the hot water tap is open. However, having multiple hot water taps open together will reduce the hot water output. Having too many hot water taps open at once will produce lukewarm water if the tankless water heater’s output capacity is exceeded.

To help you estimate the flow rates of most of your faucets, we shared some typical flow rates below. The actual flow rates may be different for your house and different appliances.

Temperature Rise

After you have calculated the flow rate of every faucet in your house, you must now determine how much heat your heater needs to generate to give you the required heat in your water outlets. We’ll take into consideration the temperature of the water that flows into your home and the temperature of the water that you want to flow out of your tap to determine the required temperature rise.

You might still have some questions relating to the size of instant electric water heater you need, please let us know in the comments below.

  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.

Below are some tips on how to choose the best tankless water heater for your home

1. Consider the size of 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.

2. Gas or Electric?

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.

3. Finding the properly sized tankless water heater for your home.

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.

4. Call a professional plumbing company.

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.

5. Easily maximize your water heater’s efficiency.

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.
