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 price of the tankless water heater itself depends on the unit's output capacity and features like Wi-Fi connectivity or built-in recirculation pumps. Beyond the unit price, you must account for the labor required to install it safely. We guide you through selecting the right model based on your home size and demand. 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 Denver

How long do hot water heaters typically last?

Most standard tank water heaters last between 10 to 15 years. Tankless models can sometimes last longer, up to 20 years with proper maintenance. The climate in Denver, with its mineral content in water, can sometimes impact lifespan. Discussing your current unit's age and condition with a pro can give you a clearer picture.

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, as they heat water on demand rather than keeping a large tank hot. This can lead to significant energy savings over time, especially in a high-demand household. A licensed pro can explain the benefits and potential installation costs for a tankless system in your Denver home.

What are signs I need a new water heater?

Common signs include inconsistent hot water, strange noises like rumbling or popping, visible rust or leaks around the tank, or water that has a metallic taste or smell. If your current unit is nearing the end of its typical lifespan, it might also be time to consider a replacement. A pro can diagnose these issues.

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

Sediment buildup in the tank is a very common issue that can lead to reduced efficiency and strange noises. Other frequent problems include faulty heating elements or thermostats, and leaks. Regular maintenance can often prevent these issues, but if you notice any problems, it's best to consult a professional.

Is it worth it to repair a water heater?

It often depends on the nature of the repair and the age of the unit. Minor repairs on a relatively new water heater are usually worthwhile. However, if the unit is old or the repair is extensive and costly, replacing it with a more efficient model might be a better long-term investment. Get a professional opinion.
