Tankless Water Heater Installation and Repair in San Francisco
When it comes to modern plumbing upgrades, few options are smarter or more efficient than a tankless water heater. At Discount Plumbing Rooter Services, we install, repair, and maintain tankless water heaters across San Francisco and San Mateo County, helping homeowners enjoy endless hot water while saving on energy bills.
What Are Tankless Water Heaters?
Unlike traditional water heaters that store and heat a large tank of water, tankless systems heat water on demand. Cold water passes through a heat exchanger, powered by gas or electricity, to deliver hot water instantly whenever you need it. That means no bulky storage tank, no standby heat loss, and no running out of hot water mid-shower.
Our licensed plumbers can install and service all major brands of tankless water heaters, including Rheem, Rinnai, Navien, Noritz, and Takagi, and we’ll help you choose the perfect system for your home and budget.
Why Upgrade to a Tankless Water Heater?
- Lower Energy Costs - Tankless water heaters can be up to 34% more energy-efficient than traditional tanks, according to the U.S. Department of Energy. This is especially true for homes with lower daily water usage.
- Longer Lifespan - With proper maintenance, tankless systems can last 20–30 years, nearly double the lifespan of a traditional water heater.
- Compact Design - No more bulky tanks! Tankless systems mount neatly on a wall, saving valuable space in smaller Bay Area homes
- Endless Hot Water - Tankless units heat water as it flows, providing an uninterrupted supply of hot water whenever you need it.
Tankless Water Heater Maintenance
Regular maintenance keeps your system efficient, safe, and long-lasting. Our professional maintenance services include:
- Flushing and descaling the heat exchanger to remove mineral buildup
- Cleaning the fan, burner assembly, and water filter
- Inspecting the igniter, flame sensor, and vent system
- Testing water flow rate and temperature settings
- Checking gas pressure and system safety components
We recommend annual service (or twice a year) if you have hard water or high water temperatures.
