Water Heater Installation & Replacement in St. George
Replace it once and get it right
Water heater installation in St. George starts with a question most people skip: is the old size still the right size? Hard water shortens the working life of a water heater in Southern Utah, and when a tank finally leaks or quits, it’s tempting to swap in the same model and move on. It pays to stop and size it properly first. Your household may have grown, a soaking tub or extra bathroom may have been added, and incoming water temperature here swings from cool winter supply to warm summer water that changes how hard the heater works.
Our plumbers look at your hot water use, fuel type, venting and space, then lay out the options: a standard gas or electric tank, a hybrid heat pump model or a tankless upgrade. We remove and haul away the old unit, install the new one to current code with proper venting and a new relief valve, and test it. Ask about protecting it with a water softener.

Water heater installation and replacement questions in St. George
What size water heater do I need?
It depends on how many people live in the house, how many bathrooms you have and whether anyone fills a large tub. A family of four often needs a bigger tank than a couple, and tankless units are sized by flow rather than gallons. We work it out with you rather than guessing from the old label.
Does a water heater replacement need a permit?
In Utah, yes. Replacing a water heater requires a plumbing permit and must meet current code for venting, relief valves and gas connections. We take care of the permit and inspection as part of the job, so the work is documented and you don’t have to deal with the paperwork.
Should I switch to tankless?
Tankless makes sense if you want endless hot water, less wasted energy and more space, and you plan to stay in the home a while. It usually needs a larger gas line and new venting, so the upfront cost is higher. Compare the details on our tankless water heater page.
Is there a discount on a new water heater?
Yes. Our $250 off a new tank water heater offer applies to tank installations in St. George, Hurricane and the surrounding area. If you’d rather pay over time, financing is available, and every installation is backed by our full service guarantee.
How do I help my new heater last?
Keep scale out of it. Flush the tank once a year, have the anode rod checked periodically and consider a water softener, which protects the heater and every fixture downstream. In St. George’s hard water, those habits can add years to a new tank and keep it running efficiently along the way.
What does water heater replacement in St. George, UT cost?
It depends on the heater and the house. The type and size you choose (gas or electric tank, hybrid or tankless) matters most, followed by any venting, gas line or electrical changes the new unit needs, code updates such as an expansion tank or new shutoffs, the permit, and how hard the old heater is to reach. Our water heater team gives you a written, upfront price for each option before work starts, the $250 tank offer comes off that price, and if the old heater is still sound we’ll quote a repair too.
