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
Electric tankless heaters are compact units that heat water instantly using high-powered electrical coils. These are ideal for small spaces or point-of-use needs, like a single sink or a guest bathroom. Because they draw significant power, it is vital to have the correct electrical wiring and circuit capacity installed. If you are considering switching to an electric tankless unit, we can evaluate your home's electrical panel to ensure it can safely support the power requirements of the system.
Frequently asked in Concord
How does a tankless hot water heater work?
A tankless hot water heater heats water on demand. When you turn on a hot water faucet, cold water flows through a pipe into the unit. A gas burner or electric element instantly heats the water. The hot water then travels directly to your faucet or appliance. This provides an endless supply of hot water without a storage tank.
