The advantage of purchasing the electric water heater

  • The most important advantage of using an electric water heater is the affordable price. Gas-powered water heaters are more expensive, with some models have double the price of an electric water heater unit.
  • Electric water heaters stand out for consumers because it lasts longer than gas-powered water heater models. Gas-powered water heaters unit need a pilot light to operate, which deteriorates over time. This deterioration needs additional maintenance when compared to electric water heaters.
  • Electric water heaters are much safer to use and install. Gas-powered appliances may be hazardous when there are leaks. So it would need extra precautions to be taken when installing gas-powered water heater units. It means it can cost extra money and time. Electric water heaters do not need a similar type of safety measure. There is no need for extra hassles, and extra costs may be avoided.
  • Electric water heaters do not need to be connected to a gas line. Every home has a connection to the electrical grid.
  • The installation cost of a gas water heater can be more expensive — the cost of installation may be a few hundred dollars more per unit to install.

How to buy the right 50-gallon electric water heater

1. The type

Before purchasing a new 50-gallon water heater, you have to know the model or the type of water heater. In today’s market, there are two types of water heaters which are the tankless model and the storage tank model.

The storage tank model means that there is a reservoir tank for storing water (holding heated water). You have to accommodate some space for the storage tank.

While the tankless model means that the 50-gallon water heater has no tank for storing the heated water. You will only need minimal space to install the tankless water heater.

2. The size

Forty gallons is the standard size water heater. The water heater unit does not require much space around it to run.

You make sure there is enough space when there is someone to come in and service the 50-gallon electric water heater. The size of the water heater depends on the hot water needs in the house.

The factor of how much hot water you need must be considered when purchasing a 50-gallon electric water heater. A large house must need a large water heater to serve all your hot water required.

It would be best if you keep in mind that the bigger the water heater, the more space it will need. A bigger storage tank water heater would need more space to serve the large tank. You will also need to accommodate a large tankless water heater.

3. Hot water requirement

Consider the number of people in your house. The typical person uses about twenty to thirty gallons of hot water every day.

The FHR (first-hour rating) will help you determine how well the unit will operate during a busy period. See the total BTU load of all of the appliances in your home that are running at the same time, such as the hot tub, the laundry, the dishwasher, the toilet, and the shower.

The GPM (gallons per minute rating) means that you can determine how many gallons of water can be filled in the tank per minute — the lower volume of water used per minute, the higher of hot water.

4. Energy source

When there is a power supply line, this is the best place to place your water heater. The 50-gallon water heater has to be powered by solar, gas, propane, electricity, or geothermal energy.

The water heater must be placed in a strategic location for easy installation and connectivity.

What you should know about water heater

1. The time for a replacement

All water heaters will provide a sign when they require to be replaced. If your water heater is about seven years old, the Department of Energy recommends that you should purchase a new water heater.

If you see the water heater is leaking, you should consider buying a new one. If you are not getting as much hot water out of it compared to its original condition, the water heater gives a sign of failure.

You should replace your water heater if the water heater is producing noisy operation, slow recovery, calcium buildup, and your water heater does not produce any hot water at all.

A water heater could last from ten to fifteen years with regular maintenance.

2. The efficiency

Water heating will contribute to about fifteen percent to twenty percent of your energy bill. The Department of Energy stated that an average household spends from $400 to $600 every year on hot water, and uses sixty-four gallons every day.

A high-efficiency water heater is very crucial because it decreases the amount of energy you use. Reduce the amount of energy means lowering your energy costs.

Each water heater is given an Energy Factor. It is a calculation of the efficiency of a water heater when running for 24 hours.

The Department of Energy counts the Energy Factor by operating a simulated use test on each model of the water heater. A water heater with a higher Energy Factor rating uses less energy.

The best and easy way to make the water heater efficient is to keep it regularly maintained. Regular maintenance will increase the lifespan.

How to maintain your water heater

1. Inspect the anode rod

  • Find the tank’s drain cock. Put a hose to it and let out a 1 gallon of water.
  • Fit one 1/16-inch socket onto the rod’s hex head under its top plate and unscrew the rod. If it is less than half-inch thick or it is coated with calcium, buy a replacement.
  • If you have the replacement, wrap the threads with Teflon tape. Put the replacement back in the tank, and tighten it tightly.

2. Drain and wash out sediment from the tank

  • Drain all of the water in the tank. Stir up the sediment on the tank’s bottom by opening the water supply valve.
  • Drain and repeat the practice until you see only clean water comes out of the hose. Close the drain cock, and refill the tank with water, and turn its power back on.

3. Temperature adjustment

  • Please search for the temperature dial on the side of the tank. When you find it, start unscrewing its cover.
  • Get a flathead screwdriver and adjust the dial to 120 degrees with it. For every ten degrees, the temperature is lessened. This lessening will save about five percent of energy costs.
  • Turn the thermostat down to the lowest setting whenever you go away from home.

4. Heater insulation

  • Purchase and cut an insulating blanket. Make sure the cut is to fit around the TPOR value, the temperature control, and pipes of the tank.
  • Wrap the side of the tank with the insulating blanket, and using a foil tape seal cuts the wrapper. Never cover the tops of gas or oil water heaters.

5. Drain the tank

  • Drain the tank about four to six times per year to get rid of sediment and debris. Do this by turning off the cold water supply.
  • Drain the water out of the tank until the water is clear. If you see the cloudy water remain to be seen, open the water supply valve again and drain the tank again.
  • By cleaning the sediment will make the unit run more quietly.

First-hour rating of electric water heater

According to the Department of Energy, to measure the proper size of a water heater for your home you need to use the water heater’s first-hour rating. This rating is the number of gallons of hot water the electric water heater  (or other water heaters) can supply in 1 hour when the tank is full of hot water.

Usually, the manual from a manufacturer or brand provides the information of first-hour rating. You need to find a 50-gallon water heater model with a first-hour rating that fits within one or two gallons of the peak hour demand for your home.

Here is how you estimate the peak hour of your home.

  • Select the time of day the whole family use the most hot water in the whole home. Count the number of family members.
  • Estimate your maximum usage or the peak hour demand of hot water during one hour of the day.

Estimating Peak Hour Demand

First-hour Rating Example

UsageAvg gal/usage Times used Gallons per hour
5 showers10x5x50
1 handwashing3x5x15
Clothes washer7x1x7
1 shaving2x1x2
    Peak Hour Demand =74 gallons/hour

The table shows a total peak hour demand of 74 gallons. Therefore, this household would need a water heater model with a first hour rating of 75 to 80 gallons.

Here is the formula of first-hour rating=

tank capacity X 0.70 + recovery rate = first-hour rating

For a 50-gallon water heater and a recovery rate of 50 gph=

50 X 0.70 + 50 = 85 gph

This formula result means that a household can get 85 gallons of hot water in the first hour of use. With this information, you discover an estimate on your daily hot water usage. Use this formula when buying a new water heater for your family.
