What affects the price

The final price for a new water heater depends on a few moving parts. First, you have to choose the right fuel source—gas or electric—and decide if you want to stick with a standard tank or upgrade to a tankless model. We also look at the physical space where it sits and whether your current venting or gas lines meet modern safety codes. If we need to move the unit or upgrade plumbing to get it up to speed, that shifts the labor involved. Exact pricing confirmed free on the call.

While you might not think about hot water as much in the summer, it is a great time to evaluate your system’s health. Because the incoming groundwater is warmer, your heater doesn't have to work as hard, making it a stress-free window to replace an aging unit before you hit the busy autumn season.

Frequently asked in Peoria

What is the average cost of putting in a water heater?

What is the most efficient type of water heater?

Tankless water heaters are generally considered the most efficient because they heat water on demand, meaning no energy is wasted keeping a large tank of water hot. This can lead to significant energy savings over time. However, initial installation costs can be higher.

What are signs I need a new water heater?

You might need a new water heater if you notice a decrease in hot water supply, unusual noises, or leaks. If your current unit is showing signs of rust or corrosion, or if it's nearing the end of its typical lifespan, it's time to consider replacement. A licensed pro can help you diagnose the problem.

What is the most common problem with a hot water heater?

For tankless units, common issues can include scaling from hard water, which can affect flow and heating efficiency. Ignition failures or problems with the vent system can also occur. Professional maintenance can often prevent these common issues from occurring.

Is it worth it to repair a hot water heater?

Repairing a water heater is often worthwhile if the issue is minor and the unit is still relatively new. However, if the repair costs are significant or the unit is old and has had multiple problems, replacement might be a more cost-effective long-term solution. A pro can advise on the best course of action.

How long do hot water heaters typically last?

Tankless water heaters generally have a longer lifespan than traditional tank models, often lasting 20 years or more with proper maintenance. The pros can assess your specific unit's age and condition. Regular check-ups can help extend its operational life and prevent costly repairs.
