Water heater thermostat — Concord, CA
Last updated: September 24, 2026
What affects the price
Replacing a water heater involves several variables that change the final bill. The main factors are the type of unit you choose—like standard tank models versus tankless systems—and the fuel source, whether gas or electric. Installation complexity also plays a role, especially if we need to update venting, gas lines, or electrical wiring to meet current building codes. Relocating a unit or upgrading to a higher capacity will also shift the bottom line.
About this service
The thermostat controls the temperature of the water inside your tank. If your water isn't getting hot enough or is scalding, the thermostat might be malfunctioning or set incorrectly. A technician can test the sensor to determine if the part needs replacement or if the issue lies with the heating elements. Exact pricing confirmed free on the call.
Frequently asked in Concord
What are the pros and cons of electric tankless water heaters?
Electric tankless water heaters offer on-demand hot water, saving energy. They are compact and don't require venting like gas models. However, they require a significant electrical supply, which can sometimes be a limiting factor. Their flow rate might also be lower than gas units, depending on the model and your home's needs.
Why do I need an expansion tank on my water heater?
An expansion tank is crucial for your water heater's safety and longevity. When water heats up, it expands. Without an expansion tank, this excess pressure can damage your plumbing system and the water heater itself. The tank provides a buffer to absorb this pressure, protecting your home.
How much does a propane tankless water heater typically cost?
What is the average cost to install a tankless water heater?
When should I consider a Rinnai tankless water heater?
A Rinnai tankless water heater is a good consideration if you're looking for reliable, on-demand hot water. They are known for their efficiency and durability. If your current water heater struggles to keep up with demand, or if you're looking to save energy and reduce utility bills, a Rinnai could be an excellent choice.
What are the benefits of an electric hot water heater?
Electric hot water heaters are generally simpler in design and often less expensive to purchase upfront. They don't require gas lines, making installation more flexible in some cases. While they can be less energy-efficient than gas models, they provide a reliable source of hot water for many homes.
How do I know if my gas water heater needs repair?
Signs your gas water heater needs repair include pilot light issues, unusual noises, or a lack of hot water. If you notice a gas smell, turn off the unit immediately and call for service. Corrosion or leaks around the tank are also indicators that professional attention is required.
