Considerations for the Best Gas Hot Water Heaters

Looking for the best gas heater may be a bit challenging, especially if you don’t know what makes a great heater. To make it considerably easier, I’m going to tell you all the important considerations to keep in mind to pick the best water heater.

The Energy Efficiency Rate

A heater’s energy efficiency rate is something you should pay attention to if you are looking for a gas heater. The energy efficiency rate lets you know how much of the supplied energy is converted into heat energy.

The higher the energy efficiency, the more energy-efficient it is. In a perfect situation, this rate is supposed to be 100%, but that is not the case in most heaters, especially gas heaters. The closer you can get to 100, the better.

Flow Rate

The flow rate is an indicator of how much hot water you can get from a heater when it’s in operation. It is normally indicated in gallons per second.

This is a very important consideration when you are picking a heater. The volume of hot water you need should determine the flow rate of the heater you choose. If you need multiple points of hot water access, then you should pick a heater that has a high flow rate, enough to cater for that.

Elevation Level

Some gas heaters don’t work past a certain level. This is because oxygen levels decrease with increasing elevation levels and as a result, gas heaters efficiency reduces with increasing elevation. If you live in a high elevation level, therefore, make sure to check whether the heater works there.

Durability

Gas heaters can be expensive and when you are getting one, you want to pick one that will serve reliably for a long time without complications.

Warranty Information

A heater should have a reasonable warranty period during which if you have issues, you can easily get assistance. The longer the warranty period offered on the heater the better but also make sure you check closely to ensure there are no loopholes.

Price

The price of the heater is also important, but be careful not to compromise on the quality in order to get something that’s less expensive. Spending more on a heater may not guarantee quality. You can buy an expensive heater that doesn’t serve you best.

Keep in mind the running cost as well. Some heaters are cheaper upfront, but will cost you more in terms of running costs. It makes more sense to get an expensive heater with a low running cost.

Size

The amount of storage space you have should guide you on the kind of heater to get. Although tankless heaters are mostly small, you still need to check the dimensions to make sure it can fit in the space you plan to install it.

Digital Control and Display

A heater with a digital control system makes it easy for you to control it. A digital display helps monitor the temperature better.

Replaceable Parts

Sometimes a part of the heater fails, and if you can’t get a replacement, you are forced to replace the whole system, which can be very expensive. For this reason, heaters with readily available parts are a better option to choose from.
