Tankless Water Heater Repair
Tankless water heaters are more efficient and longer-lasting than traditional tank-style water heaters, but they also have more components than older water heaters. When a tankless water heater has a faulty part, it is vital to fix the problem quickly to protect the life of your heater. At Tennessee Standard, our tankless heater specialists are prepared to make repairs on all mainstream tankless water heaters.

Tankless Water Heater Maintenance
Tankless water heaters have a life expectancy that is double the lifespan of a normal tank heater. The primary reason a tankless can last longer is that all the components are modular and replaceable whereas with a tank heater, when the tank starts leaking, there is no way to fix it. The best way to extend the life of your tankless water heater is to have it maintained regularly. At Tennessee Standard, we service our clients’ tankless heaters to get the maximum life out of each one!

What size tankless water heater do you need?
Tankless water heaters are all rated by the gallons per minute (GPM) they can produce. Each plumbing fixture in your home has a GPM rating for the hot water that it can use. Tankless manufacturers have formulas for adding up each fixture in the home to determine how big of a tankless water hear unit you need. Many of the complaints about tankless water heaters actually come from homeowners whose previous plumber undersized their tankless water heater to cut costs. At Tennessee Standard, our tankless water heater experts can size the perfect unit for your home so that you can have all your showers operating at the same time, and never run out of water.
How much money does a tankless water heater save?
Tankless water heaters are typically twice as efficient as their tank-style counterparts. If a tank heater is consuming $400 of energy per year, a tankless can usually get that down to $200 for the same amount of hot water consumed. The tankless heater also saves a chunk of money in the middle of its 20-year lifespan because all the tank heaters have to be replaced around year 10, but those tankless water heaters can last 20 years if maintained properly.
