Choosing the Best Under Sink Water Heater – Complete Buying Guide

Let’s make one thing simple and clear! Finding a perfect water heater with a compact size has become a difficult job these days. People often end up getting either a hefty water heater or the one with many flaws. Therefore, don’t you think that there should be a checklist of some features that you can keep as a standard while choosing a water heater? I know that your answer is probably YES.

So, let’s get started with some important features that you need to consider before selecting a perfect under sink water heater.

1. Compact Design

The reason you are choosing a water heater is that it should get adjusted in small places. In this regard, the best place to adjust a mini water heater is either under the shelf or on the walls. As in this case we are trying to find under the sink heaters, then you must choose a heater with a compact size.

Small sized heaters have got many benefits. That is, they can easily get mounted in small spaces. Plus, they can offer instant hot water without any hassle.
Therefore, your preference should be getting a compactly sized water heater if you want it to get adjusted in a small area easily.

2. Tankless or with Tank?

This option depends upon your priority. A water heater with a mini tank means that although he stored water in the tank is pre-heated, if it gets discharged, then that heater will take time to heat more water. On the other hand, a tankless water heater works without any storage of water. It directly provides heats to the water and makes it as warm as possible. In this way, even if you waste a lot of water, it will not get cold in between.

In my opinion, the priority should be to invest in tankless water heaters to avoid extra hassle and fuss. What’s the point of getting a water heater if you still have to wait for warm water after a specific time? This problem can easily be resolved if you opt for a tankless water heater.

3. Invest in Energy-Efficient Water Heaters

This is no secret that most under sink water heaters work on direct electricity. That said, I’ve seen many people complaining about the rift in their electric bills after they install a water heater at their home.

The mistake they do is that they choose a water heater which is not energy-efficient. In short, heaters made with such technology will only work when there is a need for hot water. So, they will be saving you power costs while doing their work with full efficiency.

More simply, you’ll need to find water heaters with energy-efficient technology to ensure no rift in the costs of your electricity bills. Brands like Ecosmart and ECOTOUCH are doing great work in this regard.

4. Durability Matters

In addition to other features, durability is the feature that is often ignored by people. However, never turn a blind eye on durability of the water heater you are going to get. It should be made up of premium quality materials to work for a long time. On the other hand, better quality construction also keeps the heater away from getting malfunctioned.

Therefore, do consider the overall construction of an under sink water heater before you make a final choice.

5. Budget

The last feature that you need to consider is the budget range. A water heater will normally cost you around 150 bucks. However, if you want an energy-efficient heater for your home, then keep at least 200 bucks in your pocket. I’m pretty much sure that the best under sink water heater will not cost you more than 200 bucks no matter how premium it is.

Summing Things Up:

Now that all things have been made clear regarding an under sink water heater, it’s your job to check out the updated list mentioned above and make a decision as per your priority. Keep the checklist in mind while you make a final decision.
