Expansion Tank Installation in Longmont, 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.

Gas Water Heater Installation in Longmont, CO
Gas water heaters are a popular choice in Longmont due to their efficiency and faster recovery rates. Our licensed plumbers meticulously install gas lines, make sure of secure connections and verify proper ventilation to prevent carbon monoxide buildup. We also install required expansion tanks and check for gas leaks, adhering strictly to all local safety codes.
Water Heater Installation Cost in Longmont, CO
Tank water heater installations usually cost less upfront than tankless systems. Gas tankless installs can cost more because of gas line upgrades and venting. Attic installs, relocations and code upgrades may add to the price. We provide a written quote that includes the unit, labor, permits and haul-away. We also compare long-term energy costs so you can make an informed choice.

Hybrid Heat Pump Water Heater Installation in Longmont, CO
Hybrid heat pump water heaters pull heat from surrounding air, which can make them efficient in warm garages and utility rooms. We install models from Rheem and A.O. Smith with proper condensate drainage. These units need adequate air space and clearance. They may qualify for utility rebates or tax credits. We help you decide if a hybrid is right for your home.

Tankless water heaters provide on-demand hot water, saving energy and space, and they are increasingly popular in Colorado homes. Our experts specialize in installing these highly efficient units, making sure of 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 Longmont. We'll help you choose the right model for your specific needs.

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.

Frequently Asked Questions About Water Heater Installation in Longmont
The cost of water heater installation in Longmont, CO typically ranges from $1,200 to $3,500, depending on the type of water heater (tank vs. tankless), its capacity, fuel type (gas or electric) and any needed plumbing or electrical modifications. We provide a detailed, upfront quote after assessing your specific needs.
In most areas, a plumbing permit is required for water heater replacement or installation to ensure the work meets local building and safety codes. A licensed plumber who handles permits keeps the work on record, which protects your warranty, insurance coverage, and resale value. GFR Plumbing handles all necessary permit applications and inspections in Longmont as part of our service.
The decision to repair or replace often depends on the age of your unit, the cost of the repair and its energy efficiency. If your water heater is over 10 years old, often breaks down, or the repair cost is more than 50% of a new unit, replacement is often the more economical choice. Newer models also offer significantly better energy efficiency.
A standard tank replacement usually takes two to four hours. Tankless installs or relocations can take most of a day.
Most standard water heater installations, particularly 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.
GFR Plumbing installs all major trusted brands of water heaters, including Rheem, Bradford White, A.O. Smith and Noritz. We work with both gas and electric models, as well as many sizes and efficiencies. Our team can help you choose the best brand and model to suit your hot water demands and budget.
To improve efficiency, make sure your new water heater is properly sized for your home, consider a tankless model for on-demand heating, insulate hot water pipes and set the thermostat to 120°F (49°C) to prevent scalding and cut energy consumption.
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.
