If you are in the market for a new water heater, before choosing the traditional storage tank water heater, it could be a good idea to check out different types of water heaters.
Due to the increase in their popularity, many people are looking for electric tankless water heater reviews. Perhaps you are too. Before you do that, though, how do you know an on-demand water heater, as they are sometimes known, is right for you?
The Pros and Cons of Tankless Water Heaters
Sure, if you are looking at how to hide your water heater, because you don’t want the eyesore of a big water heater or just don’t have space, a tankless model is a great option. However, you need to think about more than just one aspect of a water heater before deciding it’s right for you and your situation.
That’s why in the following post, we have put together a guide to the pros and cons of tankless water heaters. Before that, though, if you are completely new to the subject, you may need a little help in understanding what tankless heaters are.
What are Tankless Water Heaters?
In tankless water heaters, strong burners are utilized to warm water up quickly as it is passed through a heat exchanger as it’s directed into showers and faucets. Normally, they are powered by electricity or gas.
According to tests carried out by Consumer Groups, tankless units were noted as being 22% more energy-efficient than their traditional counterparts.
How Do They Differ From Storage Tank Water Heaters?
Obviously, if you are going to choose a tankless model over a storage tank heater, you need to know why it makes a difference in the first place. Storage tank systems are the kind of water heaters you’ll be most familiar with and normally have a specially insulated storage tank with anything from 30 to 50-gallons of water.
All the water held in the tank is warmed and stored there, warm, until you need it. At the top of the tank, there is normally pipework that leads directs the water around your home.
Much like tankless systems, storage heaters can be powered by either natural gas or electricity. Natural gas options are better as they use something in the region of 50% less fuel in comparison to electric storage tank water heaters. However, it’s worth noting that the electric models are more affordable than the gas heaters.
Tankless Water Heater Pros and Cons
Now that we’ve looked at what tankless water heaters are and how they differ from the more traditional option of a storage tank heater, it’s time to consider their various pros and cons. No product or appliance available these days is completely perfect in every way.
Therefore, the best way to assess whether something is a good fit for your home is to look at the advantages and disadvantages that come from using it. Then determining whether the disadvantages are things you can live with or not.
Pro #1: They Require Less Space than Storage Tank Water Heaters
water heaters without the storage tank, by default, are smaller than the more traditional option. Thanks to the lack of a big, cumbersome and unsightly storage tank, they can be installed in some incredibly tight spaces. In some smaller homes, they can even be installed on the exterior of properties.
Pro #2: Provide Hot Water on Demand
We’ve already referred to tankless water heaters as their other name of on-demand water heaters and that is a big advantage they have over the alternative. You don’t have to wait for the water to heat up, as it’s heated as it passes through a tankless system. In fact, most good systems can deliver between 2 and 3-gallons of warm water a minute.
Pro #3: They Last for a Longer Amount of Time
On-demand water heaters tend to last between 20 and 30-years, double the usual lifespan of most storage water heaters.
Pro #4: They Save Money Over Time
Gov discovered that water heaters without a tank are often more energy-efficient than their storage tank counterparts. It’s thought that they could, in theory, save around $100 a year, if they are working properly. That’s a staggering difference compared to the $34 that electric models save a year.
Con #1: They are More Expensive
The price should never be the only thing that you base buying something on, especially not a water heater. It’s still very important to consider whether a model fits in with your budget.
One major downside therefore of tankless water heaters is the fact that they are more expensive upfront. When you factor in the price of installation, particularly if it must be retrofit to your existing property layout.
Con #2: The output is Lower than What Storage Tank Heaters are Capable of
This is especially true if you or anyone in your household ever use a few different water sources at once, such as using the shower while someone does the washing up. Tankless water heaters tend to struggle with that kind of demand and do not produce the same level of pressure.
