How to Get the Best Tankless Water Heater with Installation in Santa Rosa, CA

December 9, 2025

If you are tired of running out of hot water halfway through your shower or dealing with high energy bills from your old water heater, it may be time to consider an upgrade. Many homeowners in Santa Rosa are switching to tankless water heaters because they provide endless hot water, take up less space, and save money over time.


Getting the right tankless water heater with installation in Santa Rosa, CA is about more than just buying a new unit. It requires choosing the right system, working with a reliable plumber, and ensuring proper installation for long-lasting performance. In this guide, we will explain everything you need to know about tankless water heaters, how to select the right one, and why Mike's Plumbing & Rooter Service is the trusted choice for installation in Santa Rosa.

Key Takeaways

  • Tankless water heaters provide endless hot water, lower energy bills, and a longer lifespan compared to traditional systems.
  • Choosing the right unit depends on household size, water usage, and whether you prefer a gas or electric model.
  • Professional installation ensures safe setup, optimal efficiency, and compliance with local Santa Rosa building codes.
  • Regular maintenance, including annual flushing, extends the heater’s life and maintains energy efficiency.
  • Mike’s Plumbing & Rooter Service offers expert installation, honest pricing, and dependable customer support in Santa Rosa, CA.

Why Tankless Water Heaters Are Growing in Popularity

Traditional water heaters store a large tank of hot water and keep it warm around the clock. That means they use energy even when you are not running the faucet or shower. Once the hot water runs out, you have to wait for the tank to refill and heat up again.


Tankless water heaters work differently. Also called on-demand water heaters, they heat water instantly as it passes through the system. This means you never run out of hot water and only use energy when you actually need it.


Some of the biggest advantages include:


  • Unlimited hot water for showers, laundry, and dishes
  • Lower utility bills from reduced energy use
  • Longer lifespan compared to traditional water heaters
  • Compact design that saves valuable space
  • Eco-friendly operation that reduces your household’s carbon footprint

For many Santa Rosa homeowners, the combination of energy efficiency, reliability, and convenience makes tankless water heaters the smarter choice.


Choosing the Best Tankless Water Heater in Santa Rosa, CA

Not every tankless water heater is the same, and choosing the right one depends on your home, lifestyle, and water needs. Here are some important factors to keep in mind.


Gas or Electric Tankless Water Heater

Gas-powered systems typically deliver higher water flow, which makes them better for larger families that may run multiple showers and appliances at the same time. Electric tankless units are often easier to install and maintain, making them a great option for smaller households or single-point applications like bathrooms.


Proper Sizing Matters

Your new system must be sized correctly to match your water usage. A professional plumber can calculate the right gallons per minute (GPM) flow rate to make sure you never run out of hot water. An undersized unit will struggle to keep up, while an oversized one may be more expensive than you actually need.


Look for Energy Efficiency

Choosing a model with a high energy factor rating helps you save money on monthly utility bills. Energy-efficient models are designed to minimize waste while delivering consistent hot water.


Warranty and Maintenance

A longer warranty gives you peace of mind, and regular maintenance keeps the system performing at its best. In Santa Rosa, where hard water is common, flushing the system once a year prevents mineral buildup and extends the life of the unit.


What Happens During Tankless Water Heater Installation

If you decide to upgrade, knowing what to expect during the installation process helps make things easier. Here is a simple breakdown:


  1. Home evaluation: Your plumber will inspect your current water heating system, check water lines, and help determine the best location for your new tankless heater.
  2. Removal of old unit: If you are replacing a traditional tank system, the old one will be disconnected and hauled away.
  3. Installation of new system: Your new tankless water heater is mounted and connected to water lines, gas or electrical supply, and venting if required.
  4. System testing: The plumber will check for proper flow, pressure, and temperature settings to ensure everything works safely and efficiently.
  5. Final walkthrough: Before finishing, your plumber will explain how to operate and maintain your system so you get the most out of your investment.
