Best hybrid water heater – Things To Consider


The size of the tank itself is going to be discussed next, but it’s important to understand the size of the unit as a whole. In most houses, there is only a set space where the water heater can go and anything bigger can be difficult to fit in.

Before you consider buying any water heater, please carefully measure the space you have available in your home to make sure that it is going to fit where it needs to. Be sure you are accurate in your measurements so you know exactly what fits because just one inch can make a huge difference.


Now that the size has been mentioned, it’s time to talk about the capacity of the actual tank itself. As you might already know, the size of the tank is going to refer to how much water it is able to hold and the bigger your home and the more people you have living there, the bigger the water heater you need.

While the tank is important, the most important thing to pay attention to is the gallons-per-minute rating. Most of the tanks sizes you find are going to be more than enough for your home unless you plan on using a lot of hot water in a short period of time.


When it comes to choosing which tank you are going to have for your water heater, there are a lot of different choices to choose from when it comes to the material. My personal recommendation is to look for one with a glass-lined tank because it is going to give you the best results overall and will provide you with a stronger and more durable tank. Additionally, the glass on the inside can help to ensure that you don’t deal with corrosion or any buildup inside of the tank.


While this is far from a deciding factor into which type of water heater you buy, you should put some sort of thought into the display of the heater because that is what you will use for just about everything. I recommend trying to find a simple and straight-forward design that is pretty easy to use and read.

The fancy display might seem better thanks to all of the bells and whistles, but odds are you don’t need all those features and it just makes it more difficult to change the temperature and use the display.


This is one of the more debatable features when it comes to a hot water heater and it’s tough to figure out if it really is worth spending the extra money to get a heater with this potential.

You’re going to find that it helps to reduce any scale buildup on the heater by swirling the water left on the bottom of the tank to make sure it doesn’t stay in one position. While it is a nice feature and it can be convenient to have, it’s hard to justify spending the extra money for a feature that is a luxury more than a necessity.

It’s not worth the trouble and headache of wrongly installing the unit just to save some money on installation costs.
