Storage water heaters

Majority of the water heaters available in the market right now are storage models. These units are sequestered tanks that can hold as much as 20 to 120 gallons of water that can be heated using electricity or gas burners.The water stored in the storage tank will get heated when you switch the system on and as you utilize the hot water, you will obtain a constant flow of hot water until it is almost over. Now that you know how a storage water heater works, let us take you through its advantages and drawbacks.

Advantages

The installation charges of a storage water heating unit are quite feasible when compared to other models.
 
The operating system of a storage water heater is pretty simple, which means that you will be spending less on the maintenance and repairs.
 
In the long run, if the storage unit tends to breakdown, the repair charges are not that high.

Drawbacks

When you choose a storage water heater, you have to be ready to pay greater energy bills. This is because in the storage tank if the water once heated is not utilized it just sits there and gets cold. And then when you put the system on again, it re-heats the water which in turn using up more energy. If you use these units in the colder months, they will function slower elevating your gas or electricity bills.
 
Storage water heaters require more space when compared to their instant counterparts. Hence, if you live in an already small space, a storage water heater might not be the best option for you.
 
This kind of water heater is not suitable for a house with many members, although every member will have enough hot water to use, the energy bills will rise dramatically as the unit is in constant use.
 
Storage units have a shorter service span when compared to instant units; they need to be replaced more often than instant water heaters.
Instant water heaters

Advantages

Unlike storage water heaters, instant units are highly energy efficient. If your home utilizes around 41 gallons on a regular basis, then the instant units can save up to 24% - 34% on the energy costs.
 
There is no denying the fact that the installation costs of an instant unit are higher than the storage ones. But on the brighter side, these systems provide you with a long and productive service life as they have lower operation and energy costs. In the simpler words, they will pay for themselves in the long run.
 
If you are short on space in your house, then an instant unit is just the right pick for you. Instant water heaters are small and can be easily installed even in a cramped up space.
 
One of the major benefits of an instant water heater is that you will not have to wait for the water to get heated. You will be able to get hot water instantly as and when you need it, all you need to do is switch on the system.

Drawbacks

The installation charges of an instant water heater are quite high when compared to a storage water heater. Furthermore, if you are planning to replace an old unit with a new instant one, that too will be costly. Your plumber will require more time for doing that which in turn will increase the installation cost.
 
Instant water heaters cannot be used for diverse purposes, if you want to take a shower and do the laundry at the same time, it would be difficult for you to do so with an instant unit.
Which is the better option?
When you look at it from an economic and practical point of view an instant water heater is the best option for every house owner. Although it may have its own fair share of cons, the pros definitely outweigh them. So if you are planning to install a water heater in your house, you should definitely choose instant water heaters. They live up to their name and they can be trusted to provide you with a generous flow of hot water at all times!
