What are the benefits of installing a tankless water heater in my Phoenix home?

Don Jones Plumbing • 1 July 2025

When it comes to upgrading your home’s water heating system, a tankless water heater is a modern option that offers both efficiency and convenience. Unlike traditional water heaters that store hot water in a large tank, tankless units heat water on demand, which means they only use energy when you actually need hot water. At Don Jones Plumbing, we provide expert tankless water heater installation in the greater Phoenix area. Here are five benefits of installing a tankless water heater in your home.


Endless Hot Water Supply
One of the most attractive features of a tankless water heater is its ability to provide hot water continuously. Because water is heated as it flows through the unit, there’s no waiting for a storage tank to refill and reheat. This is especially beneficial for larger households where multiple showers, laundry, and dishwashing might be happening at the same time. 


Improved Energy-Efficiency
Tankless water heaters are known for their energy-saving capabilities. Traditional water heaters constantly heat a full tank of water, even when you're not using it, which leads to standby heat loss. In contrast, tankless models only operate when hot water is needed, significantly reducing energy consumption. This efficiency can lead to noticeable savings on your monthly utility bills.


Longer Lifespan Than Traditional Units
While tankless water heaters may have a higher upfront cost, they typically last longer than conventional water heaters. On average, a tankless unit can last 20 years or more with proper maintenance, compared to 10 to 15 years for a standard tank unit. This extended lifespan helps offset the initial investment and makes the upgrade more cost-effective over time.


Space-Saving Design
Tankless water heaters are compact and can be mounted on a wall, making them an ideal solution for homes with limited space. Their small footprint frees up floor space in utility rooms, garages, or basements and allows for more flexibility in installation locations. This can be especially helpful in smaller homes where maximizing square footage is a priority.


Lower Risk of Water Damage
Because tankless water heaters don’t store gallons of water, there’s a lower risk of water leaks and tank ruptures. This reduces the potential for costly water damage to your home.
