FACTORS TO CONSIDER BEFORE BUYING 80 GALLON HOT WATER HEATER:

80 Gallon electric water heater cost ranges from $1,000 – $3,000.

Capacity:

First and the foremost factor that you need to consider before buying any hot water heater is its capacity. Capacity is actually the maximum amount of storage space the water heater tank can hold. You can determine the ideal capacity from the number of family members.

Generally, 100-gallon of water heater will be more than enough for a family of 5 members. Keeping in mind that the family does frequent dishwashing and laundry. For such a family even an 80-gallon water heater would be sufficient.

Space Availability:

Well, the availability of proper and suitable space is the second most important consideration. You need to have a proper and dedicated place where you can install an 80 gallon hot water heater. And you know what, the more spacious space is, more easier would be the installation. Also, make sure that the required plumbings should be there in your desired space.

Energy Efficiency:

Energy efficiency is again the most important and critical factor to consider. It’s a big part of what makes electric heaters a favorite among people.

It has been said that the energy used to power your electric heater can account for 14% of your utility bill. So it is advisable to select a high energy efficient hot water heater as it will lower the overall energy bills.

So before buying an 80-gallon hot water heater, make sure to read the specs on the label properly,

First Hour Rating:

First-hour rating is indeed a crucial and better indicator of the capacity of the hot water heater. A larger tank does not mean a high FHR.

FHR is actually the amount of hot water that the unit will be able to deliver during its working hour.  You can find FHR on the bright yellow Energy Guide label.

So before buying any 80 gallon hot water heater determined your peak-hour hot water needs the shop for a water heater. I am sure your heater would be capable of delivering an FHR within your peak-hour range.

Tank Lining:

Usually, water heaters have some sort of lining on the inside surface of the tank. This lining protects the tank wall from rust and corrosion. The reason is, rust and corrosion on the steel tank wall may lead to leakage, which cannot be fixed. The only option is to purchase a new water heater, which will be a big burden on your pocket.

There are some hot water heaters that use glass lining. Using glass lining is a good idea indeed but you know what, glass tends to crack or may have other imperfections. These imperfections will ultimately decrease the life of your tank.

On the other hands, you will find some hot water heater that has porcelain and polymer tank linings. This is indeed a better choice when it comes to the life of the tank.

Installation:

There are some hot water heaters that are quite basic in nature and easily connect to the standard water system. In contrast to this, there are some hot water heaters that are quite tricky and a little bit complex to install. For such a heater, you will require professional and experienced plumbers that you will charge an arm or leg. So it is advisable to always look for basic and less complex units that are simple and easy to install that even a less experienced plumber can install it.

Flow Rate:

When buying a hot water heater, always consider a unit that offers a high flow rate. The reason is, you might experience poor water flow, when you turn on several outlets at the same time.  A unit with a high flow rate will allow water to pass through faster and maintain the same pressure throughout the building. The higher the flow rate rating (in GPM) the better it would be.
