Our Water Heater Installation Services

Tank Water Heater Installation

A tank heater delivers steady, reliable hot water for years. We set the unit on a stable base, connect supply lines and relief piping, and fill and test the tank before handing over the controls.

Tankless Water Heater Installation

On demand heating saves space and ends the wait for a tank to refill. We size the unit to your fixtures, upgrade gas and venting where required, and set controls so every tap runs hot.

Natural Gas Water Heater Hookups

Gas heaters need secure connections, correct venting, and reliable combustion air. We install sediment traps and approved connectors, check draft and flue performance, and leak test every joint so your appliance operates safely and efficiently.

Electric Water Heater Installation

Electric units demand correct circuits, dedicated breakers, and secure plumbing. Our team coordinates the connection, installs relief and drain piping, and verifies heating performance so your household gets reliable, steady hot water without tripped breakers.

Venting and Gas Connection Upgrades

Old flues, undersized gas lines, and missing drip legs cause poor performance and hazards. We upgrade venting and fuel connections to code so combustion is clean, drafts are stable, and carbon monoxide risks stay low.

Expansion Tank and Safety Valve Setup

Thermal expansion strains pipes and fixtures in closed systems. We install expansion tanks, temperature and pressure relief valves, and discharge piping, then verify and set pressure correctly so your system stays safe, stable, and quiet.

Benefits of Water Heater Installation

Hot Water Back Quickly

Showers, laundry, and dishes stop being a daily negotiation when hot water returns quickly. Scheduling by noon often puts a skilled technician at your door that day, so your whole household routine recovers fast again.

Fixed Price With Nothing Hidden

Everything required to finish the job right is included in the price. Permits, insurance, and code corrections arrive built into the quote, so you can approve the work without worrying about add on charges later.

Code Compliant Setup

Venting, gas connections, relief piping, and clearance requirements all play a role in household safety. Our installations meet code and pass inspection, protecting your family and your home insurance from avoidable problems and costly corrections.

Right Sized Capacity

A heater that is too small runs out mid shower, while an oversized one wastes fuel. We calculate demand from fixtures, family size, and habits to match capacity so hot water lasts when needed most.

Lower Energy Costs

Modern heaters and tight pipe insulation reduce standby loss and fuel use. Efficient equipment, correctly installed, trims monthly utility bills while delivering steady temperatures, giving you savings that keep adding up long after installation day.

Protected by Strong Warranties

Standard 40 and 50 gallon natural gas heaters include a six year tank warranty and a two year labor warranty. That coverage turns a major household purchase into a protected investment you can rely on.

Frequently Asked Questions

    Q. How long does a water heater installation usually take?

    A. Standard tank installations usually finish within a few hours, including draining, connecting, venting, and testing. Tankless conversions, new gas lines, and venting upgrades extend that time, and we outline the full schedule during your estimate.


    Q. Should I choose a tank or a tankless water heater?

    A. Tank heaters cost less upfront and suit most households, while tankless units save space and provide continuous hot water at a higher initial price. We compare usage, gas capacity, and venting before recommending either option.


    Q. What size water heater does my household need?

    A. Sizing depends on peak hour demand, not just family size. Count simultaneous showers, laundry, and dishwasher use, and we translate that into gallons or flow rate so you never run short during busy weekday mornings.


    Q. Why does a gas water heater need special venting and combustion air?

    A. Burning gas produces carbon monoxide and moisture that must exit the home safely, and the burner needs fresh air to combust cleanly. Proper venting, draft testing, and clearances prevent backdrafting and dangerous exposure to fumes.


    Q. Do water heater installations require a permit?

    A. Most areas require permits for water heater work because gas, venting, and relief piping affect safety. Our fixed price includes permitting and insurance, and we arrange the inspection so your installation is documented and approved.


    Q. What maintenance keeps a new water heater working longest?

    A. Flush the tank yearly to remove sediment, test the relief valve, and check the anode rod every few years. Those simple habits slow corrosion and protect efficiency, extending service life, especially where water is hard.


    Q. What does the fixed price at Same Day Water Heater Pros include?

    A. Our fixed price at Same Day Water Heater Pros in Denver, CO is built to cover everything needed to finish properly, including old water heater removal, permits, insurance, and code updates at no extra charge.


    Q. Why do installers at Same Day Water Heater Pros recommend certain brands?

    A. With 35 years in Denver, Lakewood & Littleton, CO, our Same Day Water Heater Pros installers know which brands, venting layouts, and capacities hold up well, and we explain every choice so you approve the system with confidence.
