water heater Buying Guide
Here’s What to Look for When Buying a Water Heater
When it comes time to replace your water heater, you have a few factors to consider. The most important decision is what type of water heater you want. Storage tank water heaters are the most common type and come in a variety of sizes. Tankless water heaters are becoming more popular, but they can be more expensive to install.
In addition to the type of water heater, you need to decide on the features that are important to you. For example, do you want a model that has a timer so you can set it to come on at specific times? Or do you want one with a remote control so you can adjust the settings without having to get up?
Once you’ve decided on the features you want, it’s time to start shopping for a new water heater. Here are some tips for finding the best one for your needs:
-
Look for a model with an Energy Star rating. This means that the water heater has been certified as energy efficient by the Department of Energy.
-
Compare the cost of running different models. Some water heaters use more energy than others, so it’s important to find one that is affordable to run.
-
Choose a size that is appropriate for your needs. If you have a large family or run a business from home, you’ll need a larger water heater than someone who lives alone.
-
Make sure the water heater fits in the space you have available. Measure the dimensions of the space where you plan to put it and compare them to the dimensions of the selected model.
Once you’ve selected a water heater, it’s important to read through the installation instructions carefully before beginning installation. If you’re not comfortable installing it yourself, hire a professional contractor instead.
How to Choose the Right Water Heater for Your Home
In the market for a new water heater? If you’re like most people, you may be feeling overwhelmed by all of the choices available. How do you know which one is right for your home?
Here are a few tips to help you choose the right water heater for your needs:
-
Size matters. When choosing a water heater, be sure to take into account its size. You want to make sure that it’s large enough to meet your needs, but not so large that it takes up too much space or becomes too expensive to operate.
-
Consider your budget. Another important factor to consider when choosing a water heater is your budget. Remember that you will need to factor in the cost of both the purchase price and the operating costs of the unit.
-
Choose an energy-efficient model. When it comes time to choose a water heater, be sure to select an energy-efficient model. Not only will this save you money on your energy bills, but it will also help reduce your carbon footprint.
-
Think about your needs. What are your hot water needs? Do you have a large family or run a business out of your home? If so, you’ll need a larger water heater that can handle higher volumes of hot water demand.
-
Consider your location. Another thing to keep in mind when choosing a water heater is where you live and the climate conditions there. If you live in an area with cold winters, you’ll need a tankless model that can heat water on demand rather than storing hot water in a tank.
Now that you know what to look for, it’s time to start shopping for a new water heater!
10 Things You Need to Know Before Buying a Water Heater
There are many factors to consider when purchasing a water heater. The most important decision is what type of water heater to buy. The two main types of water heaters are storage tank and tankless.
Storage tank water heaters come in gas and electric models. They hold a certain amount of water that is heated and kept hot until it is used. These water heaters are cheaper to purchase but more expensive to operate.
Tankless water heaters only provide hot water as needed, so they don’t use energy when the water isn’t being used. They also last longer than storage tank models. However, they are more expensive to purchase and may not be able to handle large households or homes with high demand for hot water.
Before you buy a water heater, consider the following:
1) What type of fuel is available for your home?
2) How big of a unit do you need?
3) What climate you live in?
4) What size your home is?
5) How many people will be using the hot water?
6) Do you want a tankless or storage tank model?
7) What features are important to you?
8) What is your budget?
9) Will any special permits be required for installation?
10) How much maintenance will the heater require?
The Ultimate Guide to Buying a New Water Heater
A water heater is a household appliance that heats water to provide either hot water for washing or heating, or both. In the United States, water heaters are typically fueled by natural gas, liquefied petroleum gas (LPG), oil, or electricity.Water heaters can be tankless or storage tank models.
Storage tank water heaters have tanks that hold anywhere from 20 to 80 gallons of water. When the tap is turned on, cold water enters the tank and flows through a pipe into the bottom of the heater. There it passes over a burner that heats the water. As the heated water rises to the top of the tank, it flows out through a pipe and into the household plumbing system. Storage tank models usually cost less to install but cost more to run than tankless models.
Tankless or instantaneous water heaters do not have any storage tanks. They heat only as much hot water as is needed at any given time, which can save energy. However, they typically cost more to buy and install than storage tank models. Tankless models also require either a gas line or an electric outlet to be installed near where you will use the hot water.
The size of your family and how often you use hot water are two factors that will help you decide if a new water heater is right for you. If you have a large family and take long showers, you will need a bigger model than someone who lives alone and takes quick showers. The Consumer Energy Center provides an online tool called “What Size Water Heater Do I Need?” that can help you figure out what size your home needs (www.consumerenergycenter.org/residential/water-heaters/water-heater-size).
Once you have determined that you need a new water heater, there are several things to consider when purchasing one:
1) Type of fuel – Gasoline burners are almost twice as efficient as electric ones, so if your home already has a gas line, a gas model would be most cost-effective in the long run;
2) Tank capacity – Measure how much space is available in your home for a new water heater and choose one with a similar size tank;
3) Energy efficiency – Look for an Energy Star label when shopping for new appliances;
4) Warranty – Most manufacturers offer at least a five-year warranty on their tanks;
5) Installation – Be sure to hire a qualified plumber to install your new unit correctly;
6) Recycling – Many municipalities accept used appliances for recycling; please check with yours to see what their policies are.[1]

Frequently Asked Questions(FAQ)
How can I conserve energy with my water heater?
Water heater failure is a common problem that can have a variety of causes. Some of the most common causes of water heater failure include:
-
Corrosion: Over time, the metal in a water heater can corrode, leading to leaks and other problems.
-
Sediment build-up: If sediment builds up in the tank, it can cause the water heater to overheat or even burst.
-
Blocked vents: If the vents are blocked, it can prevent the hot air from escaping, leading to overheating.
-
Malfunctioning thermostat: A malfunctioning thermostat can prevent the water heater from heating up properly, leading to poor performance or failure.
-
Frozen pipes: If the pipes in your home freeze, they can burst and damage your water heater.
What should I do if my water is discolored after a heater replacement?
Installing a water heater blanket is one of the easiest ways to conserve energy with your water heater. A water heater blanket wraps around the tank and helps keep the heat in, which saves you money on your energy bill. You can also save energy by turning down the temperature on your water heater to 120 degrees or less. This will help prevent scalding accidents, and it will still provide plenty of hot water for your needs. Another easy way to conserve energy is to install a low-flow showerhead. This will reduce the amount of water that flows through the showerhead, which means that less energy is needed to heat the water. Finally, make sure to properly maintain your water heater so that it runs as efficiently as possible.
How long will a water heater last?
Water discoloration is a common issue that can occur after a heater replacement. If your water is discolored, there are a few things you can do to remediate the issue:
1) Run the cold water for a few minutes. This will help clear out the discolored water and improve the water quality.
2) Check your aerator screens for any blockages. If there are any blockages, remove them and run the cold water for a few minutes.
3) Check your faucet nozzles for any blockages. If there are any blockages, remove them and run the cold water for a few minutes.
4) If none of the above methods work, you may need to call a plumber to further assess the situation.
Can I install a tankless water heater myself?
A water heater will generally last anywhere from 5-10 years, but there are many factors that can affect how long it will actually last. The quality of the unit, the hardness of your water, and how often it is used all play a role in how long a water heater lasts.
If you want to get the most out of your water heater, it is important to maintain it properly. Make sure to flush the tank regularly and check for any leaks. If there are any problems with your unit, be sure to have them repaired as soon as possible.
Replacing a water heater can be expensive, so it is important to do your research and buy a unit that will last as long as possible. There are many different types of water heaters available, so be sure to choose one that is right for your needs.
A good rule of thumb is to replace your water heater every 10 years, but this may vary depending on the type of unit you have. If you are unsure whether or not it is time to replace your water heater, consult with a professional to get their opinion.
Should I cover my water heater during the winter?
Yes, you can install a tankless water heater yourself, but it’s not always easy. While many models are designed for do-it-yourself installation, each unit’s specifications may vary, so be sure to read the installation instructions thoroughly.
Here are some general tips for installing a tankless water heater:
-
Check your home’s voltage and amperage to make sure they can support a tankless water heater. Most units need between 190 and 240 volts of electricity and between 30 and 40 amps of current.
-
Locate the place where you want to install the unit and measure its dimensions to make sure it will fit. Also, be sure there is enough ventilation space around the unit.
-
Shut off the water supply and drain the old system by opening all the faucets in your house until they run dry.
-
Disconnect the old water heater and remove any insulation or protective covering from the pipes.
-
Follow the manufacturer’s instructions for connecting the tankless water heater to your home’s plumbing system. Be especially careful when soldering copper piping, as this can be tricky. If you’re not comfortable doing it yourself, consult with a professional plumber.
-
Reconnect the water supply and turn on the faucets to check for leaks. If everything looks good, turn on the power and enjoy your new tankless water heater!
What are some common causes of water heater failure?
If you have an outdoor water heater, there is no need to take any special precautions during the winter. Your water heater will do just fine in the cold weather. If you have an indoor water heater, you will want to cover it during the winter. This is because the cold weather can cause your water heater to work harder and use more energy. You can buy a water heater cover from your local hardware store.
