What affects the price

Replacing your water heater involves several variables that change the final bill. The biggest factor is the unit type—tankless models usually cost more upfront than traditional tank-style heaters due to installation complexity. You also have to consider the fuel source, as switching from gas to electric often requires electrical panel upgrades. Size matters too; a larger home needs a unit with higher recovery rates. Finally, local building codes might require additional safety equipment, like expansion tanks or updated venting.

About this service

A tankless unit heats water directly as it flows through the device instead of keeping a large reservoir hot. You should consider this upgrade if your household frequently runs out of hot water during showers or if you want to reclaim space in your utility closet. Because these units only heat water on demand, they are more efficient than traditional tanks.

Frequently asked in Peoria

When is a water heater expansion tank needed?

A water heater expansion tank is often necessary when your plumbing system is closed, meaning it has a check valve or pressure reducing valve. When water heats up, it expands, and this tank provides a space for that expanded volume. This prevents excessive pressure buildup that can damage your water heater and pipes. A professional can confirm if your system requires one.

How is tankless water heater maintenance performed?

Tankless water heater maintenance typically involves flushing the unit to remove mineral deposits, especially in areas like Peoria with hard water. Technicians also inspect the heat exchanger, burners, and venting for any signs of wear or obstruction. Regular maintenance ensures optimal performance and extends the lifespan of your unit. This prevents costly repairs down the line.

What are the pros of a storage tank water heater?

Storage tank water heaters provide a consistent supply of hot water readily available. They are generally less expensive to purchase and install upfront compared to tankless models. For households with moderate hot water needs, they are a reliable and straightforward option. Their operation is simple and familiar to most homeowners.

What types of natural gas water heaters are available?

Natural gas water heaters come in both traditional storage tank models and energy-efficient tankless options. Storage tank models offer a large capacity for continuous hot water. Tankless units heat water on demand, providing endless hot water and saving energy. Both require a natural gas line and proper venting.

What factors affect tankless water heater installation cost?

The cost of tankless water heater installation is influenced by the unit's brand and model, as well as your home's existing plumbing and venting. Upgrades to gas lines, electrical wiring, or venting may be necessary for optimal performance. A professional quote will detail all necessary components and labor for your specific situation.

What issues might an RV water heater repair address?

RV water heater repairs can address various problems, including leaks, ignition failures, or lack of hot water. Common causes can be faulty thermostats, heating elements, or gas valves. Ensuring your RV water heater is functioning correctly is crucial for comfort on the road. Professional service can restore it to full working order.

What is a tankless water heater?

A tankless water heater, also known as an on-demand water heater, heats water only when you need it. Instead of storing hot water in a tank, it heats water as it passes through the unit. This offers significant energy savings and a continuous supply of hot water. They are a modern and efficient alternative to traditional tank heaters.
