When Should I Replace My Hot Water Heater

Electric Hot Water Heaters Cost More Every Year

Thinking about REPLACING YOUR Electric WATER HEATER?   Why NOT Replace? Water heating is typically the second largest energy expense in your home. It can account for as much as 30% of your monthly utility bill. As water heaters age, their efficiency fades and you may not have a complete failure, but a gradual loss of efficiency is inevitable. This can continue for years before the water heater finally fails.

Update:  For a family with only 3 or less people in the home, we can make a strong case for installing the New Hybrid Electric Hot Water System.....  

For larger families, This article will show that the rising cost of electricity makes a strong case for replacing that electric hot water tank with a Solar Hot Water System


That Electric Tank is Quietly Wasting Your Money

Unfortunately, many homeowners wait until their water heater fails before shopping for a replacement. However, over time, the cost of purchasing and operating a fully functional water heater can be much less than the cost of running an older, inefficient water heater. A family of five or more could be spending over a thousand a year on electric hot water.


Anatomy of a Water Heater Buying Guide
The best way to determine the right water heater for your needs is to look at the number of people in your home and the amount of demand you have for hot water. This includes dishwashers and washing machines. Homes with teenagers, oversized bathtubs, whirlpools and spas generate a higher demand on the water heater. Always anticipate your family's future needs when selecting your water heater. Solar 5 or more, should use 120 gallon tanks...

Household Size Demand Gas Electric
5 or more Regular 50 or 75 Gallon 80 Gallon
High 75 Gallon 120 Gallon
3 to 4 Persons Regular 40 Gallon 50 or 65 Gallon
High 50 or 75 Gallon 80 Gallon
2 or Less Regular 30 Gallon 40 Gallon
High 40 Gallon 50 Gallon
Solar    5 or more, should use 120 gallon tanks...

                            ​Again, For Smaller Families, we should discuss the                              Hybrid Electric Hot Water System!

The average life expectancy of a water heater is between 8 and 15 years. Don't wait for an emergency to occur before thinking about replacing yours. In addition to avoiding cold showers and a soaked basement, replacing your unit with a new high-efficiency water heater is much more energy-efficient than those manufactured 10 or 15 years ago.

Since water heating is the second largest energy expense in your home, the money you save on energy can help pay for the cost of a new one. But, does it make sense now to go to Solar Hot Water?

Replace My Electric Hot Water Tank With Solar?​

Years ago, the cost of electricity was just a few cents per kilowatt. But now the average price per kilowatt in Florida is about 15 cents.  What this means is the old hot water heater was a pretty good deal when electric rates were so low, but now represent up to 30% of the total electric bill.

Yellow Sticker Hot Water Tank

The Yellow Sticker Test

Most Electric Hot Water tanks still have the yellow sticker on the side of the tank. This sticker is required by law to show the efficiency of the ​tank when it was new. The big number in the middle is the estimate of the annual operating cost a minimum amount of water per day. But this is based on the old electric rates, so most people have to add more to this. 

For example, if the yellow sticker says the annual rate number is based on 10 cents, and the current rate is 15 cents, then the number is 50% too low.  If the tank is over 10 years old, ​ average electric rate shown is about 7 cents per kilowatt. That would mean the sticker is off by double.....

Replacing the old inefficient electric hot water tank with solar becomes a simple math problem. ​ The basic electric tank uses at least 400 kilowatt hours a month, according to the big yellow sticker on the side. (And that's when it was new... who knows how much it uses years later) 

​This means that with most families of 3 persons, it is costing about 50 per month for electric, add about 15 dollars more per person from there. On average, a family of 5-6 is spending at least 75 dollars a month on an old hot water tank. They are probably running out of hot water too!

Bright Energy Central will do the math with you, and in most cases it becomes clear that it is cheaper to install solar hot water. The break even period is about 5 years, and then it is free. But, it's more than just cheaper.

Solar Hot Water tanks are much better insulated.​

Solar Hot water tanks are glass lined, with solid foam insulation. They are designed to keep water hotter without having to reheat.  Compare this to Electric tanks which constantly are reheating the same water due to poor insulation.​

​Solar Hot Water Tanks are Bigger

The average electric hot water tank ​is about 50 gallons. The average solar hot water tank is 80 gallons. That's a big difference when you are dealing with back to back showers. Anyone who ever tried to fill up a tub knows the old electric hot water tank won't keep up!
