What Size Water Heater For A 3 Bedroom House? 3 Best Tips!

Do you know what size water heater for a 3 bedroom house? Dear friend, a water heater with a capacity of 35 to 45 gallons will be enough for several such consumers – assuming that the house has a maximum number of three lodgers given the number of bedrooms. Nevertheless, taking the time to think of what size of water heater you will buy is a sage act. People often think that having a bigger tank is always better and more secure, but that is not practical. You may be sure that you will never run out of hot water, but it will consume so much energy. 

The counterpart, which is the smaller tank, will, of course, cause you a terrible headache. You may get shocked by the sudden change of water temperature as you take your bath. Oh, that is so frustrating. However, the market is now offering a “tankless” water heater, which can be a good choice. Nonetheless, if you are one of the wise people who assess their needs before buying a desirable product, then this article is for you. My friends, there are more things that you should know, so without further ado, let’s start!

Tips To Know The Size Water Heater For A 3 Bedroom House

Now that we have an overview of what size water heater for a 3 bedroom house, let us dig deeper, especially to discover the basic mechanics of choosing the right water heater. However, you must take note that the given answer to our central inquiry above is just a loose estimate for that particular number of persons. It is best for you to have your needs calculated. This section will present two things that you can do to have a more accurate calculation of the volume of hot water that will be enough for your household. 


#1. Know your home’s first-hour rating

The first-hour rating, simply known as FHR, is the measurement of the amount of hot water that the water heater is capable of producing during hours that are very busy. One example of these active hours is in the morning when everybody fixes themselves to go to work or school. This measurement is indicated on the water heater’s energy guide label that is colored yellow. However, there is another way to check it yourself. 

With these simple steps, you will be able to determine what size of water heater is perfect for you. The first thing you must do is assign for each person in your house – in our case, three – 12 gallons of water. Then, add 1 to this number. Now we have a total number of four. Multiply this number to the number of gallons allotted for each consumer – twelve times four. The answer we have is 48. This is your first-hour rating. Knowing this will help you choose the right size of water heater in a faster way.


#2. Look out for the energy factor

Energy factor or EF is also located on the water heater’s energy guide. You have to consider this because the higher it is, the more proficient your water heater is. You may have known the FHR you need, but you may still choose the wrong water heater without knowing the EF. In choosing the right water heater, pick the one with the FHR fit for your household that is going side by side with its energy factor – better to choose the highest option. Back then, manufacturers would typically use very complicated tables for the customer’s guide. But now, we can do it the easier way. 


#3. Consider tankless water heater

Maybe it’s not too late for you to change your mind regarding the type of water heater you are going to buy. One better option is to choose a tankless water heater. The truth is, having a water heater at home is such a convenience for the household, especially showering on a cold day. However, you may not be at ease with the conventional water heater when you run out of hot water or see your electric bill increase so much after installing a giant water heater tank. 

You don’t have to consider the size of the tankless water heater since it heats the water just when you need it. With that said, we can see that energy is conserved, and so is your time in solving the required values so that you will not wrongly estimate the kind of conventional water heater you will buy. Just take note of what you must ensure to do as preliminaries before installing the tankless water heater.

One of the preliminaries is to contact your gas company to know the proper size of the gas main. Most tankless water heaters need more gas than those enormous residential heaters. You may install the tankless water heater yourself, or you can call a professional for you to get the job done. You must also take note that the installation process may vary with the fuel type, safety issues, climate, and so on. Therefore, it is best to leave the installation to a professional.
