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

The cost to install a tankless system depends on your home’s infrastructure, such as venting requirements and the size of your gas meter. Because these units provide on-demand heat, the installation process is more technical than a standard water heater replacement. We provide a full assessment of your home to determine the final investment required for a seamless upgrade. 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 Fort Collins

How long do hot water heaters typically last?

Standard tank water heaters generally last between 8 to 12 years. Tankless water heaters can often last longer, potentially up to 20 years with proper maintenance. The climate in Fort Collins and water quality can influence the actual lifespan of your unit.

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 the most energy-efficient option. They heat water only when you need it, eliminating standby energy losses that occur with traditional tank systems. This can lead to significant energy savings for households in Fort Collins.

What are signs I need a new water heater?

Signs that indicate you need a new water heater include a decreased hot water supply, discolored or rusty water, or leaks from the unit. If your water heater is making unusual noises or is nearing the end of its expected lifespan, it's wise to consider a replacement.

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

A common issue is a lack of hot water or insufficient hot water, often caused by a faulty heating element or thermostat. Sediment buildup can also reduce efficiency and create noise. Leaks from the tank or pipe connections are also frequent problems.

Is it worth it to repair a water heater?

Repairing a water heater can be a good option for minor issues on a relatively new unit. However, if the repairs are extensive or your water heater is old, it might be more cost-effective to replace it. The pros can assess your situation in Fort Collins and provide guidance.
