Considerations for Getting the Best-rated Water Heater

Getting the best-rated water heater on the market can be tough when you don’t even know what to look for in the first place. For this reason, I’m listing the most important considerations that will guide you in picking the best water heater.

Hot Water Flow Rate

A heater’s flow rate determines the hot water you will get from a heater. The higher the indicated flow rate, the more water you can get from your heater.

You should choose a heater based on the amount of hot water you need for your home. The larger the volume of hot water you need, the higher the flow rate of the heater you pick should be.

Energy Cost

The cost of running a water heater is another factor you should keep in mind. This cost will majorly depend on the fuel type for the heater you choose.

Electric water heaters, while they are the most eco-friendly, can be very expensive to run because the cost of electricity is higher than other fuel options available. For this reason, electric water heaters are most suitable for small families whose hot water volume requirement is low. If you need a lot of hot water, on the other hand, natural gas heaters are a better option as they are more economical in fuel cost.

Are the Parts Replaceable?

Sometimes parts of a heater fail, especially electric water heater elements. When this happens, it is easier and more affordable to replace the damaged part than do away with the whole unit.

This can only happen if the heater’s parts are replicable and readily available. When this is not the case, you might be forced to replace the whole unit, which is expensive.

Warranty Information

A heater you purchase should have a solid warranty. This ensures that you are making the right choice and should anything go wrong, you have a warranty to fall back on.

A good warranty should be of reasonable duration and also simple to invoke. You should also be able to easily seek help from the manufacturer’s support team.

Size

Depending on the storage space you have, you should pick a heater that can fit into your available space. Luckily, with the current tankless technology, most heaters feature a small compact design significantly smaller than old tank heaters. If you go with these types of heaters, you don’t need much space to install one.

Digital Control and Display

Heaters with digital control systems give you a lot of control over your heater. You can set the water temperature more precisely.

Unlike with traditional heaters, a digital control system heater is easy to control, even when you are not around the house. It’s possible to put it into vacation mode when you leave your house.

Elevation Level

Some heaters are designed to work up to a certain elevation level. If you are buying a water heater, especially natural gas heaters, you should keep this in mind.

Best Rated Water Heaters Frequently Asked Questions

1) What’s the best heater to use in high altitude areas?

As I have already stated earlier, the elevation level of the area you live in should be one of the things to keep in mind when getting a water heater. A natural gas heater’s efficiency declines with increasing elevation levels, due to decreasing levels of oxygen in the air. For this reason, if you live at high elevation levels past 4000 ft, an electric water heater may be a more appropriate choice.

2) What’s the energy factor and is it important in a heater?

A heater’s energy factor spells out how energy efficient the heater is. It’s the rate at which a heater converts the energy applied to heat energy. It’s an important factor you should consider when getting a heater. The higher the energy factor, the more energy-efficient it is.

3) Does spending more on a heater mean better quality?

Although quality heaters can be expensive, buying an expensive heater does not guarantee quality in a heater. There are many factors you should keep in mind depending on your hot water requirements. This should form the basis of your decision on what heater to buy.

Conclusion

Deciding what heater to buy is not as simple when you don’t know what to look for in one. When you know what to consider, however, things can get a lot easier.

In this article, I have highlighted all you need to know to make an informed choice as far as the best-rated heaters are concerned. The four heaters in this list are great choices.
