Water heaters are a common sight in most homes and are considered to be an essential fixture. There are many different brands of water heaters available in the market. Each water heater is unique as every model has different features and specifications. As a result, choosing the right water heater for your home becomes a difficult task.
Before setting out to shop for a water heater for your home, you should consider these factors.
The size of your home – If the size of your home is very large then it is a good idea to get a tanked water heater. If you want a tankless heater then installing one in every bathroom would be convenient.
The daily need for hot water – Analyze your family’s need for hot water. Calculate the amount of hot water that you need on a daily basis. Choose a model that will give you the desired amount of hot water quickly.
Availability of fuel – Tankless water heaters run on propane, gas or electricity. If you want a fuel-based water heater then check the availability of fuel in your area beforehand.
Features needed – Newer models of water heaters have different features. Look out for a water heater that has the features you need.
Space for the water heater – Decide a specific space for your water heater in the home. Choose a model that will fit in that space. If you are opting for an outdoor water heater, choose a space away from the elements. This will help in keeping the tankless water heater durable for a long time.
Depending on these factors, you should select the best option that meets your needs.
Types of Water Heaters
Water heaters can be divided into 2 types depending upon their storage type.
Tanked Water Heaters – These water heaters have been around for a long time. These are often used to meet the hot water needs of the entire house. The tanked water heaters are bulky and heavy as they have an in-built storage tank for hot water. These heaters occupy more space and are not durable for a long time.
Tankless Water Heaters – The tankless water heaters are also called instant water heaters. This is because the user can get hot water immediately with the touch of a button. The tankless water heaters are compact and lightweight. They can be installed in small spaces and are designed to be energy efficient.
How Does a Tankless Water Heater Work?
It is important to understand how a tankless water heater works before buying one for your home. It will help you to understand how to best use the water heater to fulfill your needs.
Working Mechanism of a Tanked Water Heater – A traditional tanked water heater stores water and heats it. In this model, the water in the tank is heated continuously to ensure that the user gets the hot water when needed. Tanked water heaters use more energy as the water is maintained at a set temperature in the tank. This extra energy that is spent on keeping the unused water hot in the tank is called standby heat loss.
Working Mechanism of a Tankless Water Heater – These water heaters only heat the water according to the user’s need. The tankless water heaters do not waste energy and do not have standby heat loss. As a result, the tankless water heaters are more energy-efficient than others.
A few important things that you need to know and understand about tankless water heaters are
Things to Understand About Tankless Water Heaters
Heat Exchanger – A tankless water heater uses a heat exchanger to increase the water’s temperature. This is a device that works by transferring heat from one source to another. Heat exchangers are common in car radiators, air conditioners, and refrigerators. In tankless water heaters, the incoming flow of water activates the heat exchanger. When the hot water tap is turned on, the incoming water circulates through the exchanger. This heats up the water at your set temperature.
Lag Time – The time taken while waiting for the hot water to reach the faucet from the heater is called Lag Time. If the lag time is more then your water consumption bill will become high. This means that even though your power bill is going down, your water bill will go up. This will stop you from making savings even though you are using a tankless water heater. This lag time differs from model to model as there are many different types of water heaters. The most popular sizes are the whole house water heaters and point of use heaters.
Whole house water heaters – These heaters are large in size and are more expensive. The whole house water heaters can work with more than one outlet at any time. The lag time for these water heaters can run up to several minutes if the home is a large one.
Point-of-use water heaters – These water heaters are small with the capacity to heat one or two outlets. Due to their size, they can fit in your closet or under a cabinet. As a result, the lag time for point-of-use water heaters is lower than in other models.
Power – The tankless water heaters can run on propane, gas or electricity. The whole house models are usually natural gas or propane powered. The point-of-use water heaters can run on either electricity, propane or gas. It is important to select a water heater model depending upon the availability of fuel in your area. Another important thing that you need to consider is the cost of fuel.
Choosing The Best Tankless Water Heater For Your Home
There are a wide variety of tankless water heaters in the market. It is a difficult task to choose one for your home. Each tankless water heater has different features. Before buying a water heater check for these features.
Important Features of Tankless Water Heaters
Energy Efficiency – Tankless water heaters are more energy-efficient than tanked water heaters. To ensure that you do make some savings check the EF rating on the water heater before buying. Higher EF (Energy Factor) indicates higher efficiency of the water heater. Buying a tankless water heater that has a higher EF will ensure that you save more on your energy bills. But, you should also consider the cost of operating the water heater for an exact calculation. The operating cost of a tankless water heater depends on its model.
Electric Tankless Water Heater – The operating cost will be more as the cost of electricity is more.
Gas Powered Tankless Water Heater – The operating cost will be less as gas is cheaper. The operating cost of tankless water heaters varies according to their model. A gas-powered heater gives a 70 F temperature rise if it has a flow rate of 5 gallons per minute. But, an electric model will only deliver up to 2 gallons per minute for the same temperature rise.
Output Capacity – Check the output capacity of the tankless water heater to ensure that it meets your needs. The heater should be able to deliver a minimum of 2 gallons of hot water per minute. Tankless water heaters that have an output of 5 gallons per minute are ideal for residential use. Gas-powered tankless water heaters are popular as they can provide a higher flow rate. Choosing a tankless water heater that has a hot water output of 8 gallons per minute is a safe bet. Laundry machines and dishwashers can be supplied with hot water from the heater.
Temperature – When choosing a water heater, check its temperature rise. This will help to ensure that the heater can give the desired output of hot water. Temperature rise is the difference in temperature between the groundwater and output. The temperature of the groundwater keeps changing according to the climate. The temperature of the groundwater impacts the flow and speed of the water heater.
Fuel – The type of fuel that a tankless water heater runs on greatly influences its operating cost. Most people opt for tankless water heaters in an attempt to lower their energy costs. This happens only when the water heater gives a steady output of hot water. Electricity, propane, and gas are the 3 different types of fuel that tankless water heaters can run on. The type of fuel available in your area is a huge factor that will influence your selection.
Tip: Compare the cost of fuel type to understand the operating cost of the water heater. Use this information to select your water heater.
Fuel Supply Line – The fuel supply line for your water heater should be of the proper size. A correct sized fuel line will help the water heater to give instant hot water output. Most gas tankless heaters have an output of about 200,000 BTU.
Ignition – The ignition system on the water heater affects the user’s savings. Tankless water heaters that have simple ignition systems have lesser savings. Expensive water heaters often have a complex ignition system that conserves fuel. This, in turn, leads to a lower energy bill for the user.
Venting – Tankless water heaters that run on gas need vents for proper functioning. Picking Category 3 vents is ideal as they support better combustion. Vents are necessary for indoor gas-based tankless water heaters. Outdoor gas-based water heaters do not need venting. These water heaters need to be installed away from the elements to prevent damage. When choosing an outdoor heater model select one that has antifreeze features. This will help to enhance the durability and keep it from getting damaged by the elements.

A few tips to follow while draining out your tankless water heater are:
- Make sure to empty both the water lines that run to and from the unit.
- Look out for check valves as they will stop water from draining out completely from the heater.
- Blow air through the water pipes to ensure that water comes out completely.
Is it advisable to install my own tankless water heater?
No. Tankless water heaters should be installed by professionals only. You should not try to install your tankless water heater by yourself for a variety of reasons like
Warranty – The warranty becomes valid only if they are installed by professionals.
Damage – The water heater might get damaged during self-installation. This can happen due to a lack of understanding of proper installation procedures.

I read that you cannot install some tankless water heaters in certain areas. How true is that?
Yes, it is true. In some states and cities, the installation of some water heaters are prohibited. The reasons for such laws vary from place to place. To ensure that you buy the right water heater:
- Check with your local authorities before buying or ordering your water heater.
- Check your local code restrictions and ensure that your water heater is compliant.
- These steps will help you to avoid getting stuck with an unwanted water heater.
Why don’t any of my tankless water heaters show the first-hour rating?
The first-hour rating is a measure that is used to calculate the hot water output in a tanked water heater. Tankless water heaters will not show the first-hour rating as they do not have a storage tank. Instead, the tankless water heaters have a gallon per hour rating that is used as a measure of water output. The temperature of the input water to a tankless water heater impacts its flow rate. The colder the water, the higher will be the output flow rate and vice versa.
Which is the best temperature to heat my incoming underground water?
The best water temperature cannot be determined as it varies from person to person. Some people might prefer hot water while others might prefer warm water. The temperature of the incoming groundwater changes according to the climate. As a result, we cannot determine the right water temperature for incoming water. Water temperature that is between 90ºF to 100ºF is considered to be ideal.
Exactly how much will a tankless water heater save me?
It is difficult to determine the exact amount of money that you will save by using a tankless water heater. This is because your savings depend upon a lot of factors like:
Hot water usage – If there is a higher demand for hot water in your home then the power or gas bill will be high. You will not be able to see much savings due to higher water consumption.
Cost of gas – It is important to calculate the price of gas, propane or power when using a water heater. The prices of fuels fluctuate over time causing a change in your energy bills.
