Tankless Water Heater Installation & Repair FAQs

What is the lifespan of a tankless water heater?

The lifespan of a tankless water heater depends on whether it was properly installed, how frequently it’s used, and if it’s being maintained. When AHWA installs your unit, you can expect it to last for over 20 years with regular maintenance. Get the most mileage out of your unit and save money when you choose us for installation and repair.

How many tankless water heaters are needed in a home?

Usually, households only require 1 tankless water heater, but the size of your home and how much hot water you use can be important factors. If you often find your hot water running out, you may be better off opting for 2. Consult our technicians for an accurate estimate.

How do tankless water heaters work?

Tankless water heaters are just that: water heaters that don’t require a tank to function. Rather than storing the water in a tank and reheating all of it every time, the water instead runs through piping and heats up as it travels towards you. Not only is this method more convenient, but it’s also energy-efficient and lets you save on your electric bill.

Are tankless water heaters safe?

Tankless water heaters are safe to use as long as they’re installed correctly. If danger is a concern, you can rest assured knowing that many units come with safety features that shut down the unit when it detects malfunctions, protecting you and your living environment. Of course, improper installation can still lead to gas leaks and carbon monoxide poisoning. This is why it’s important to get your units properly installed and repaired with our fully qualified technicians.

Which is better: an electric or gas tankless water heater?

Both types of units are equally cost-effective, but gas units are typically more reliable and quicker at heating. Electric units tend to heat water slower, and you may notice that you run out of hot water more frequently with an electric unit.

How much does a tankless water heater cost?

The cost of having a tankless water heater installed and owning one can fluctuate, depending on your location, as well as the amount of resources needed to install or repair a unit. AHWA offers competitive pricing in Phoenix, AZ. To get the most out of your purchase, you’ll also want a high-quality unit.
