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

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 Baltimore

How long do hot water heaters typically last?

Traditional tank water heaters typically have a lifespan of 10 to 15 years. Tankless water heaters often last longer, potentially reaching 20 years or more with consistent maintenance. Local water hardness can play a role.

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 energy-efficient option. They heat water on demand, meaning you avoid the energy waste of keeping a large tank of water hot at all times.

What are signs I need a new water heater?

Look for indicators such as a reduced supply of hot water, water that is discolored or has a strange smell, and any visible leaks around the unit. Unusual noises like popping or rumbling are also important signs.

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

For tank heaters, pilot light issues or a malfunctioning thermostat are common. Sediment buildup within the tank can also lead to decreased efficiency and noise. Regular flushing is recommended maintenance.

Is it worth it to repair a water heater?

Repairing a water heater is often a good choice for newer units with minor problems, such as a faulty heating element or valve. If your unit is aging and requires extensive repairs, replacement with a new, more efficient model might be more cost-effective.
