Benefits of a Tankless Water Heater Installation

Tankless water heaters continue growing in popularity. So, if it’s time to replace your worn-out tank system, here are a few reasons to consider going tankless.

Energy & Cost Savings

Tankless water heaters are more energy-efficient than tank-style systems, which means they cost less to operate.

Unlimited Hot Water

If you have a large family with high hot water demands, you know how frustrating it is to be the last one in the shower in the morning. You won’t ever find yourself stuck taking a cold shower with a tankless system because the hot water supply has been exhausted. 

Less Space

If your home is tight on space, a tankless system can be wall-mounted and is no larger than a suitcase. They are compact and take up much less space than a traditional water heater. 

Less Maintenance

One major downside of tank-style water heaters is sediment accumulation in the tank, which reduces efficiency, causes corrosion, and eventually leads to leaks. While tankless water heaters aren’t immune to such issues, they’re far less likely to escalate to the point where the system leaks and fails.

Longer Lifespan

On average, tank-style water heaters last between 8 and 12 years, but tankless systems can easily last over 20. So, while they’re more expensive to install, you get a greater return on investment in energy savings and system longevity.

If you’re intrigued by getting a tankless water heater installation, call our plumber to schedule a consultation.

What is a Point-of-Use Water Heater & Do You Need One?

A point-of-use water heater is installed close to the sink or appliance where you need hot water to eliminate the wait time. These systems reduce wait time and prevent water waste. Also, you can attach a point-of-use right onto your existing system without redoing your plumbing.

Almost everyone has dealt with the scenario of turning on the hot water and waiting for a minute or two before hot water comes out from the tap. The greater the distance the tap is from the water heater, the longer it takes for the hot water to get there, and this is where a point-of-use system comes in.

FAQs

Should I get a tankless water heater or a traditional one?

Tankless models are ideal for Arizona’s dry climate, as they save energy and provide unlimited hot water. However, traditional tanks are more affordable upfront. The experts at Grand Canyon Home Services will be happy to provide you with quotes and information for both, so you can make an informed decision based on your household’s needs.

What size water heater do I need?

A typical family in Arizona might need a 40–50-gallon tank, but tankless water heaters are also an energy-efficient option we can install for endless hot water. For tankless systems, the flow rate (in gallons per minute) must match the number of fixtures you run at once. Most homes need a unit rated between 6 and 10 GPM. A licensed plumber can accurately size the system based on your usage.

What is the average tankless water heater cost in Phoenix?

The average cost in Phoenix ranges from $2,000 to $4,500, including installation. Pricing depends on the unit size, fuel type, installation complexity, and any upgrades needed to the existing plumbing.

How important is flow rate & sizing for a tankless water heater?

Flow rate & sizing for tankless systems ensure it meets household demand. Undersized units can’t supply enough hot water for multiple fixtures, while oversizing wastes energy.
