Question 1

Are tankless water heaters worth it?

Accepted Answer

Yes, they are highly worth it for homeowners who plan to stay in their house long enough to recoup the initial installation costs through consistent energy savings, or those who place a premium on having a continuous, endless supply of hot water for a large family.

Question 2

Do tankless water heaters require special venting?

Accepted Answer

Yes, high-efficiency gas tankless units create acidic condensation and operate at lower exhaust temperatures. They cannot safely use standard metal B-vents used by traditional tanks and require dedicated concentric or PVC venting routed directly through a roof or exterior wall.

Question 3

Will a tankless water heater work during a power outage?

Accepted Answer

Most modern gas tankless water heaters rely on electricity to power the digital control board and ignite the internal burners. Unless you have a battery backup system installed, the unit will not generate hot water during a power outage.

Question 4

What is the average payback period for a tankless water heater?

Accepted Answer

The average payback period typically ranges from seven to 12 years, depending on your local energy rates, household water consumption, and the initial installation cost. You can shorten this timeframe significantly by taking advantage of federal tax credits and local utility rebates.

Question 5

How many years does a tankless water heater last?

Accepted Answer

With rigorous annual maintenance and proper water quality management, the life expectancy of a tankless water heater is easily 20 years or more. This is significantly longer than traditional storage tank heaters, which typically succumb to internal rust and begin leaking between 10 and 15 years.

Question 6

Can one tankless water heater run two showers at the same time?

Accepted Answer

Most standard gas models can comfortably run two simultaneous showers, provided the unit has a GPM rating of 5.0 or higher. However, if you live in a cold climate where the groundwater is freezing, the unit's flow rate will drop as it struggles to heat the water, resulting in lower pressure.

Question 7

Can I install a tankless water heater myself?

Accepted Answer

We strongly advise against taking this on as a DIY project. The installation process involves complex and dangerous natural gas connections, high-voltage electrical wiring, and strict exterior venting work that must adhere to local building codes. Improper installation will almost certainly void your manufacturer's warranty.
