Tankless Water Heater Installation
Getting your unit sized correctly is everything. Too small, and you'll run cold during peak demand. Too big, and you've spent money you didn't need to.
Our tankless water heater installation process starts with a home evaluation. We measure your real hot water demand in GPM (gallons per minute), count your fixtures, and figure out how many showers, faucets, and appliances might run at once. From there we calculate the right BTU input and flow rate for your household.
We handle the details that make or break a job:
- Gas or electric upgrades when your existing lines can't supply enough fuel
- Proper venting for condensing and non-condensing units
- Water line connections with isolation valves for easy future maintenance
- Indoor or outdoor placement, including compact wall-mounted setups that free up floor space
- Startup, programming, and performance testing before we leave
Whether you want a whole-house tankless system or a small point-of-use water heater for a far-off bathroom, we'll spec it to fit your home. We install gas and electric models, plus hybrid heat pump water heaters for folks who want a high-efficiency electric option.
Tankless Water Heater Replacement
If your old storage tank is leaking, rusting, or just can't keep up, replacement is the smart move. We'll be honest with you, though. Sometimes a repair makes more sense than a swap, and we'll tell you straight either way.
When replacement is the right call, we remove your old unit, update plumbing and gas connections to current code, and set you up with a continuous hot water system built for your family's needs. Many homeowners use this moment to step up from a basic tank to an ENERGY STAR®: certified tankless or hybrid model with a higher UEF (Uniform Energy Factor) and lower operating costs.

Tankless Water Heater Maintenance and Descaling
Here's the thing about Utah water: it's hard, and that mineral content builds up fast inside a tankless unit. A yearly tankless water heater flush keeps your system running at full efficiency and protects your warranty.
Our maintenance visits include:
- Annual flushing and descaling to clear limescale
- Cleaning the inlet water filter
- Inspecting venting for safety
- Checking the recirculation pump
- Verifying flow rate and efficiency rating
Skip this step and minerals slowly choke the heat exchanger. Stay on a regular schedule and your tankless heater can easily last 20 years or more, far longer than a standard tank.
Gas vs. Electric and Choosing the Right Unit
Gas tankless units deliver higher flow rates and work well for larger families, while electric models are simpler to install and great for smaller homes or as a point-of-use water heater. Hybrid heat pump water heaters offer impressive efficiency for all-electric homes. We'll walk you through the trade-offs based on your household size, fuel source, and budget, then match you with a condensing or non-condensing unit that fits.

Frequently Asked Questions About Tankless Water Heaters in Salt Lake City
What is a tankless water heater and how does it work?

Why is annual flushing important for tankless water heaters in Utah?
