Signs you need a new tankless water heater
You should consider replacing your current tankless unit if it:
- Is more than 10 years old. Most tankless water heaters only last 10–15 years. If yours is coming up on that age mark, you might want to start looking at getting a new one.
- Has needed a lot of repairs lately. Repair costs add up quickly. Sometimes, it’s more cost-effective in the long run to invest in a new, efficient unit than to keep repairing your current one.
- Is increasing your energy bills. An increase in energy bills is usually a sign that your unit is losing efficiency. When your bills increase but usage stays the same (and nothing else is wrong with the unit), you should consider looking for a replacement.
- Has an expired warranty. An invalid warranty means the manufacturer will no longer cover the cost of a part on your unit if it dies. That means you’ll have to pay for the entire repair cost yourself.
Tankless water heater terms you should know
If you’re shopping around for a tankless water heater, you’ve probably seen some unfamiliar terms. We’ll explain the lingo for you.
- Flow rate: Tankless hot water heaters are sized by their flow rate, which is how many gallons of water per minute (GPM) a unit can heat based on your temperature rise (see below). Flow rates range from 4 to 8 GPM. To give you a better idea of what flow rate your unit would need, running 2 showers and a dishwasher would require a flow rate of 3–6.5 GPM.
- Temperature rise: Temperature rise is the temperature of the incoming water (groundwater) subtracted from your desired hot water temperature. For example, if you want hot water at 115°F and the groundwater in Charlotte is, on average, 60°F, you’d need a unit that can provide a temperature rise of 50°F (115 − 60 = 55).
- Energy factor (EF): Tankless water heater energy efficiency is measured by its energy factor, which is the amount of hot water produced per unit of fuel consumed in a typical day. The higher the energy factor (ranging from .5 to .95), the more efficient the unit.
