What affects the price

When you are looking at the price of a new water heater, a few main things shift the final number. The type of unit you choose—whether it is a tank model or a tankless system—is the biggest factor. You also have to consider the fuel source, like gas or electric, and the physical space where the heater sits. If your home needs new venting, updated piping, or a different hookup to meet current safety codes, that adds labor time to the project.

About this service

Electric tankless heaters provide a steady stream of hot water using high-voltage heating elements. Because they require significant power, we ensure your home’s electrical panel can handle the load before installation or repair. You need this service if the unit is losing power or failing to heat during peak usage. Exact pricing confirmed free on the call.

Even though it is warm outside, your water heater is still working daily. Summer is a great time to adjust your settings, as the incoming water isn't as cold, which can actually help extend the life of your unit. If you are planning a home renovation or just want to upgrade to a more efficient model, call us to talk through your options.

Frequently asked in Jacksonville

How long do hot water heaters typically last?

Traditional tank water heaters typically last about 10 to 15 years. Electric tankless water heaters, on the other hand, are built for durability and can often provide reliable service for 20 years or more. This longer lifespan can mean greater value for Jacksonville homeowners over the unit's life.

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

What is the most efficient type of water heater?

Electric tankless water heaters are widely recognized for their high efficiency, as they heat water only when it's needed, eliminating the energy waste associated with keeping a tank of water hot. This on-demand heating is particularly beneficial for managing energy costs in a large geographic area like Jacksonville.

What are signs I need a new water heater?

Signs that you may need a new water heater include a noticeable decrease in hot water volume, strange noises like rumbling or popping, or visible water leaks. Discolored hot water or a sudden increase in your energy bills are also strong indicators that your current unit may be failing.

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

For tank water heaters, sediment accumulation is a common issue that can affect performance and lead to noise. Tankless models, especially those using electricity, can experience mineral scale buildup, particularly in areas with hard water. Regular professional maintenance is key to preventing these problems.

Is it worth it to repair a hot water heater?

Repairing a water heater is often a sensible option for newer units with minor issues. However, if your water heater is aging and requires costly repairs, it might be more cost-effective to invest in a replacement, especially an energy-efficient electric tankless model. Consider the long-term savings.
