Considerations for the Best Quality Water Heater

When you are looking for the best quality heater, there are important factors you should pay attention to get it right. Let’s look at them.

Warranty

A warranty helps protect you against defective heaters. It also helps you replace one of the parts when something breaks.

In most cases, a reasonable warranty is an indication that a manufacturer believes in their product, and this inspires confidence in buyers. Normally, the longer the warranty period, the better – but you should also pay attention to the fine print in terms of conditions. A solid warranty shouldn’t be too restrictive.

The volume of hot water you need in your home is an important consideration to keep in mind. This depends on the size of your family. If you have a large family, you will need a large volume of hot water. For this reason, you should pick a water heater that can supply a large volume of hot water at a reasonable cost.

Size

The storage space you have determines the size of the water heater you should get. A small compact design may be ideal for you if you don’t have much space for storage.

Durability

Heaters can cost a lot and when you get one, you want to get one that can stand the test of time. Although nothing lasts forever, a quality heater should have a solid construction that will serve you for a long time.

Flow Rate

A heater’s flow rate is an important factor to consider when you are buying one, especially a tankless heater. The flow rate indicates the volume of hot water you can get from a heater per minute. The higher the flow rate, the more water you can get from a heater.

If you have a large family, you want to get a heater with a higher flow rate enough to cater to your family’s needs.

Energy Cost

The most common water heaters use either gas or electricity. Although electricity is the most eco-friendly option out there, it can be expensive using electricity to heat a large volume of water.

For a household with more people, you might want to get a gas water heater. Gas heaters are more economical when heating large amounts of water.

Tankless water heaters also help save a lot of energy, because they only turn on when hot water is needed, and therefore don’t depend on standby heat energy.

Best Quality Water Heater Frequently Asked Questions

1) I always have to let the water run when I open the faucet. What can I do about it?

Having to flush cold water from the system is both inconvenient and wasteful. Nowadays, you can buy a heater with recirculation technology that recirculates water in your pipes before you have to use it. This eliminates the wait time.

On the other hand, you can install a mini-tank water heater to complement the main heating unit, which also helps eliminate the wait time.

2) What’s a heater’s energy factor?

A heater’s energy factor is the rate at which the heater converts the energy supplied into heat energy. The higher the energy factor, the more energy-efficient a heater is.

When you are getting a heater, you typically want one that has the highest energy efficiency rate.

3) Are tankless water heaters better than traditional tank heaters and why?

Tankless water heaters have revolutionized the way we heat waters in our homes by cutting the energy heating costs by more than 30% in most of the cases. Besides, tankless water heaters are not susceptible to corrosion and leakages which make them last longer than tank heaters.

So, yes, tankless heaters are better than traditional tank heaters and much more economical to run because they only use energy when hot water is required. They also provide an unlimited amount of hot water.

Conclusion

Getting the best quality heater for your home’s hot water needs can be a bit hard sometimes, because of the many options you have to choose from. When you know exactly what to look for, however, the search becomes way easier for you.

I hope that this guide has helped explain what you need to look for when you are looking for a quality heater to get the best results. This list featured four quality heaters, all of which would serve you well, depending on your requirements.
