You might be wondering whether you need one unit or two, right?

Let's find out...

But, before that let's have a quick look at the flow rate of both electric as well as gas tankless water heaters.

In fact, a typical electric tankless water heater comes with a flow rate of 2 GPM.

On the other hand, a gas tankless water heater, in general, has a flow rate of 5 GPM.

It is really very important for you to understand that the number of tankless heaters that you would be needing depends upon quite a few factors including flow rate, temperature rise, type of heating source, and most importantly, distance to the farthest outlet source from the centralized heating system.

At the same time, you need to be very clear with the concept of desired temperature rise in order to make an informed buying decision.

The temperature rise can be defined as the desired temperature (output) of the water minus the water temperature (input) entering the tankless heater.

The easiest way to decide on the number of units of tankless water heaters that you might be needing is by deciding the sizes of your household on the basis of consumption of hot water.

Let's understand it with an example.

If the consumption of water per day in your house is more than 85 gallons then definitely, you would be needing two units of a tankless water heater.

On the other hand, if the consumption of hot water is less than 40 units then one unit is more than enough to deal with your hot water requirement on a day-to-day basis.

You can also use a point-of-use tankless water heater exclusively for the farthest outlet from the centralized water system.

Frankly speaking, point of use tankless water heater can do wonders if you're looking for a miniature tankless water heater for use at one outlet.

Do You Need More Than One Water Heater for Your House?

Well, the answer to this query depends to a large extent on the type of tankless water that you're planning to install.

For example, if you're planning to install a tank-styled conventional water heater then one unit would be enough for your house.

However, the problem with these traditional units is that they come with a higher operating cost because of the standby heat loss problem.

These units use a tank to store hot water and as a result, the heat gets lost to the environment especially if you're a resident of a cold climatic zone.

Also, they are bulky and need a good amount of space for installation.

To sum up, even though a single unit can do the trick for you, the additional costs and lack of advanced features makes it NOT a very good choice in the current scenario.

On the other hand, a tankless water heater has seen a surge in demand because of its efficiency, low-maintenance cost, and ability to provide on-demand hot water.

Tankless water heaters can be categorized mainly into two categories, that is, gas tankless water heater, and electric counterpart.

The gas tankless water heater can be further segregated into the natural gas tankless water heaters and propane tankless water heaters.

Moreover, you can also find commercial tankless water heaters that are exclusively meant for industrial use.

Well, I've been using a tankless water heater for quite some time, and trust me, it's worth the investment.

Not only are these little beasts economical and convenient but also equipped with advanced and innovative features.

You can either choose a whole house tankless water heater or a couple of point-of-use tankless water heaters whichever suits your requirements.

To sum up, if you're opting for a tankless water heater then you've got the option to choose from single or multiple units whichever suffice your requirements.

Wrapping Up

I'm damn sure that your quest for the query is one tankless water heater enough for a house would've ended here.

Again, I'm reiterating, if you're opting for a tank-styled conventional tankless unit then a single unit would do the trick for you.

On the other hand, if you're giving preference to a tankless unit over a traditional unit then you've got a CHOICE to choose from.

Depending upon your hot water requirement, you can opt for a single or multiple tankless hot water heater.

Last but not least, we always recommend our clients to opt for a tankless water heater because of the idiosyncratic feature that it is equipped with.

That's all, as of now :):):)
