Storage Water Heater
It is really hard to take cold showers in the morning or at night, especially if it is winter. That is why water heaters are a primary staple in any household. But what exactly is a storage tank water heater, how does it work, is it the right type of water heater for my home?
Let’s all find out the answer together!
Storage tank water heaters are the most popular and conventional type of water heater. It comes in various sizes, capacity, and can be operated by gas, electricity, and solar.
Usually, a storage water tank can hold from 20 to 80 gallons of hot water at a given time. When you need a hot and steamy shower, your hot water is always ready to go.
Pros and Cons
There are various advantages and disadvantages of storage tank water heaters, here are a few:
- \Low upfront and installation costs
For a household with a tight budget, storage tank water heaters are something you should definitely look into.
- \Affordable maintenance, repair, and replacement
- \Easy to operate
- \Choose from various power sources
In choosing, it is best to ask a professional. He or she will ask and check the structure — electric circuitry and gas line — in your home and give proper advice on which one is the cheapest and more beneficial for your household and your home.
- \Enough hot water supply
However, keep in mind that it takes a few minutes to heat all the water inside the tank.
- \Hot water on demand (even when there is power outage)
However, you need to turn off your water supply. Why? Because cold water will automatically enter your storage tank water heater when the water level is reduced. Cold water will be mixed into your hot water, resulting in a lukewarm or worst cold water.
- \Energy Star Certified
Study shows, the average hot water used in any Canadian household is 75 liters on a daily basis. And using water heaters, whatever type they might be, will cost a few bucks. But don’t worry, a lot of new storage tank water heaters are Energy Star certified. So, it is possible for you to save energy and money while using your storage tank water heaters.
- \Higher utility bills
Maybe you noticed the increase in your electricity or gas bills during winter. The cold temperature cools down the water inside the tank faster, needing reheating more often compared to summer.
- \Inflexible installation
- \Takes a lot of space
- \Short lifespan
- \Limited supply of how water
Keep in mind, the amount of hot water is limited to the capacity of your tank. If your tank’s capacity is less than the advised capacity for your whole household, there will be chances when your family members will be shocked with cold water while showering.
- \Energy wastage
How does a Storage Tank water heater work?
Whatever your power source for your storage tank water heater is, the main process is still the same. Here is what happens inside the tank to help you visualize what is happening inside:
- \Cold water enters the tank through the water pipes leading to the bottom part of the tank.
- \Cold water is heated at the bottom where a burner (for gas powered heaters) or a heating element (for electric powered heaters) is located.
- \The next step is pure science, hot water rises. (Try putting hot water on a bucket with cold water in it. Don’t mix the water. Put your hands all the way inside the bucket. Notice the changes in temperature. You can feel the hot water at the top part and the cold water at the bottom. That is what happens inside the storage tank water heater.)
- \A smaller pipe is located at the top part of the tank where hot water is carried to the pipes leading to the faucet and shower.
- \Water keeps entering to maintain a certain level of water inside the tank.
- \The water inside the tank keeps on being reheated to achieve a certain preset temperature until the hot water is used.
Electric Tank Water Heater
As the name suggests, this type of storage tank water heater is powered by electricity. When it comes to installation, electric tank water heaters are more flexible and easy to install because they don’t require any venting. That being said, a lot of house owners still go for the traditional gas powered options because of the running cost. Electric units consume a lot of electricity, depending on the utility cost in your area, this type might be inconvenient.
Power-vented Gas Tank Water Heater
The main selling point of the power-vented gas tank water heater is its flexibility. Inside the tank, there is a motorized blower which pushes the exhaust gases through the exhaust pipes. This pipe can be located almost anywhere, if you install a horizontal pipe, in the house making it more flexible and convenient compared to conventional storage tank water heaters.
Additionally, this type of storage tank water heater decreases the potential of any backdraft from happening. This is because of the built-in exhaust system which pushes the exhaust gas out of your water heater.
Conventional Gas Tank Water Heater
This type of storage tank water heater is more inflexible compared to your power-vented. It requires a very specific vertical venting through the house roof or chimney. This vent is located at the top part of the tank where exhaust gases pass through, naturally.
When installing the conventional gas tank water heater, it needs to be close to the vertical vents limiting the location of your storage tank.
