Gas Water Heater Replacement in Boulder
Many homes in Boulder use natural gas for their water heaters due to its efficiency and low operating costs. When replacing a gas water heater, precise gas line connections, proper ventilation and carbon monoxide detection are critical. Our licensed plumbers are experts in gas appliance installation, ensuring every safety measure is met. We check for leaks, test the igniter and confirm proper exhaust, following all local Colorado codes. You can trust us to safely and effectively install your new gas water heater, providing reliable hot water.
Tankless Water Heater Installation in Boulder, CO
Tankless water heaters provide on-demand hot water, saving energy and space, and they are increasingly popular in Colorado homes. Our plumbers specialize in installing these highly efficient units, ensuring proper gas line sizing or electrical service upgrades if needed. We also address venting requirements, which are often different from traditional units. While the upfront cost can be higher, the long-term energy savings and endless hot water supply make them an attractive option for many homeowners in Boulder. We'll help you choose the right model for your specific needs.
Expansion Tank Installation in Boulder, CO
Many homes have a pressure reducing valve or check valve that creates a closed system. When water heats and expands, pressure can rise and stress pipes and relief valves. An expansion tank absorbs that extra pressure. We install and pre-charge the tank to match your water pressure. This protects your new water heater and pipes.
Electric Tank Water Heater Installation in Boulder, CO
Electric tank water heaters are common in homes without natural gas service. We install models with the correct voltage and breaker size for your electrical panel. These units do not need venting, which allows more flexible placement. We also install a drain pan when the heater is in a closet or attic. Electric models are simple, reliable and quiet.
Water Heater Expansion Tank Installation in Boulder
Many plumbing codes require the installation of an expansion tank with a new water heater, particularly in closed-loop systems. A licensed plumber who handles permits keeps the work on record, which protects your warranty, insurance coverage, and resale value. An expansion tank protects your water heater and plumbing system from excessive pressure buildup, which can be caused by the heating process. Our installation service includes correctly sizing and installing the expansion tank to support proper system operation and prevent premature wear on your new water heater and other plumbing fixtures in Boulder. This small component offers real long-term protection.

Gas Tank Water Heater Installation in Boulder
Gas tank water heaters provide strong recovery and are common in many local homes. We install 40, 50 and 75 gallon models with proper venting and combustion air. Each install includes a new gas connector, sediment trap and shutoff valve. We check draft and test for gas leaks. Gas units are a solid choice for families with high hot water demand.

Frequently Asked Questions About Water Heater Installation in Boulder
A standard 40 to 50 gallon tank water heater usually costs $1,600 to $3,500 installed. Tankless installations often run $3,000 to $6,500 depending on gas line and venting needs.
An expansion tank absorbs excess water pressure created as water heats up inside the tank. Many homes in Boulder, CO, especially those with closed-loop plumbing systems, are required by code to have an expansion tank to protect the water heater and plumbing system from damage.
In most areas, a plumbing permit is required for water heater replacement or installation to confirm the work meets local building and safety codes. A licensed plumber who handles permits keeps the work inspected, which protects your warranty, insurance coverage, and resale value. GFR Plumbing handles all necessary permit applications and inspections in Boulder as part of our service.
New water heaters usually come with a manufacturer's warranty on the tank and components, usually ranging from 6 to 12 years. GFR Plumbing also provides a labor warranty on our installation work, giving you peace of mind. We will discuss exact warranty details for your chosen unit during the consultation.
While it might seem like a DIY project, water heater installation involves working with gas lines, high voltage electricity and water connections, all of which carry serious risks if not handled correctly. Improper installation can lead to leaks, gas explosions, electrical fires and carbon monoxide poisoning. It can also void your warranty, and local codes often require a licensed plumber for this work.
Common signs that you might need a new water heater include a lack of hot water, rusty or discolored water coming from the hot tap, banging or rumbling noises from the tank, visible leaks around the base of the unit and an age of 10 to 15 years or more. If you notice any of these issues, it is best to have a professional inspection.
We install Rheem, A.O. Smith, Bradford White, Navien, Rinnai and other trusted brands. We recommend models based on reliability, warranty and budget.
Most standard water heater installations, especially for replacing a similar tank unit, can be completed within 3 to 4 hours. However, a conversion from a tank to a tankless system, or installations requiring significant plumbing or electrical modifications, might take a full day or longer. We will provide an estimated timeline during our initial assessment.
