What Is A Tankless Water Heater And How Does It Work

Tankless water heaters, sometimes called on demand water heaters, heat water only when you open a hot water tap. Instead of storing 40 to 75 gallons in a tank, the unit senses water flow, fires a burner or heating element, and delivers hot water as it passes through the heat exchanger.

In Utah, tankless systems are especially popular in custom homes, remodels, and energy conscious households that want steady hot water and better efficiency. When they are properly sized, installed, and maintained, they can last many years and deliver excellent performance. When something in that chain is off, you start to feel it in cold showers, error codes, or intermittent hot water.

If you want to dive deeper into tankless pros and cons and other high efficiency options, our educational articles on our blog are a great place to start.

How Tankless Systems Deliver On‑Demand Hot Water

Here is what happens inside your tankless unit when you open a hot water tap:

  1. A flow sensor detects water movement and sends a signal to the control board.
  2. The gas burner or electric element turns on and starts heating the water passing through the heat exchanger.
  3. The internal sensors monitor inlet temperature, outlet temperature, and flow rate.
  4. The control board modulates the flame or power to reach the target temperature.

If any part of this sequence is off, your system will either shut down or deliver inconsistent temperatures. Mineral buildup from Utah’s hard water, blocked filters, weak gas supply, venting issues, and failing sensors are all common reasons we are called out for tankless water heater repair.

Our job is to quickly identify which part of this process has failed and restore it safely and efficiently.

Signs Your Tankless Water Heater Needs Professional Repair

Tankless water heaters are smart systems. They usually let you know early when something is wrong. The key is not to ignore those warning signs. Responding quickly can protect your system and often keeps repairs simpler and more affordable.

Below are some of the most common signals that it is time to schedule professional tankless water heater repair in Utah.

Lukewarm Or Inconsistent Water Temperatures

If your showers keep drifting from hot to lukewarm, or you cannot run two fixtures at once without losing temperature, something is off.

Common causes include:

  • Scaling on the heat exchanger restricting proper heat transfer
  • Incorrect temperature settings or flow issues
  • A failing temperature sensor or flow sensor
  • Undersized unit for your household’s actual demand

Trying to fix this yourself by randomly adjusting settings or swapping parts often makes things worse. Our licensed techs know how to test components, check gas input and flow rates, and distinguish a sizing problem from a mechanical failure.

Error Codes, Warning Lights, And Strange Noises

Modern tankless heaters display error codes when something inside is not right. Flickering lights on the control panel, repeated reset requirements, or codes that keep coming back are all red flags.

Some issues we see often along the Wasatch Front include:

  • Flame failure or ignition codes
  • Exhaust or venting related errors
  • Overheat and high limit shutdowns
  • Condensate drainage issues

You might also hear rattling, popping, or whistling sounds. These can point to scale buildup, fan issues, or problems with combustion.

If you are curious how we approach diagnostic work on other water heater types, our guide on who to call when your water heater is not working walks through our general process.

Leaks, Low Water Pressure, Or No Hot Water At All

Any tankless water heater leak, even a small one, should be treated as urgent. Leaks can damage the unit’s electronics, surrounding walls, and flooring, and can quickly grow into a much more expensive problem.

Other serious warning signs:

  • No hot water at all, even after trying multiple fixtures
  • Sudden low water pressure only on the hot side
  • The unit cycles on and off rapidly while in use

These symptoms can be related to clogged filters, failed valves, damaged heat exchangers, or supply issues that require a professional to diagnose safely. Our emergency plumbing services are available 24/7 when a tankless failure becomes a true emergency, like during a winter cold snap in Salt Lake City or Park City.

Why Professional Tankless Water Heater Repair Is Safer And More Effective Than DIY

We understand the temptation to troubleshoot a tankless heater yourself. Online videos make it look simple. In reality, these systems combine gas, electricity, combustion, and advanced electronics. One wrong move can lead to safety risks, property damage, or expensive repairs later.

Our focus is on safe, code compliant, long term solutions, not quick DIY fixes.

Complex Gas, Electrical, And Venting Requirements

Tankless water heaters rely on a precise balance of gas, airflow, exhaust, and electrical power. Problems here are not always visible, which is why we use professional diagnostic tools and follow manufacturer and Utah code requirements on every job.

Common hidden risks with DIY attempts include:

  • Incorrect gas pressure or orifice sizing creating carbon monoxide hazards
  • Improper venting that allows flue gases to enter the home
  • Inadequate combustion air in tight mechanical rooms
  • Overloaded electrical circuits on electric tankless units

Our technicians are trained to recognize these issues quickly and correct them the right way.

How DIY Attempts Can Void Warranties And Increase Costs

Most tankless water heater manufacturers require licensed professional service for warranty coverage. Removing covers, swapping internal parts, or adjusting gas components on your own can void that coverage.

We often see homeowners who started with a small DIY repair and ended up with:

  • Damaged circuit boards from incorrect wiring or water intrusion
  • Stripped gas fittings that now need replacement
  • Ongoing performance issues because the root cause was never addressed

What this really means is that DIY can turn a simple repair into a full replacement. It is rarely worth the risk.

Benefits Of Hiring A Licensed Tankless Water Heater Repair Specialist

When you hire a licensed local specialist like Glacier Plumbing and Hydronics, you get:

  • Fast, accurate diagnostics from techs who work on tankless systems every day
  • Safe gas, venting, and electrical work that meets Utah codes
  • Honest recommendations based on your home, usage, and budget
  • Access to manufacturer approved parts and repair procedures
  • Protection through our 100% satisfaction guarantee and price matching

You can explore our broader water heater services in Utah to see how seriously we take long term system reliability.

I had the pleasure of working with Jackson when he came out to help diagnose an ongoing issue with my boiler, and I couldn’t be more pleased with the service he provided. Jackson spent two full hours with me, carefully reviewing all possible issues, heating up and helping me identify the direction of my radiant heat lines under my flooring and explaining the different options available to resolve the problem. His knowledge of boilers was outstanding—far superior to any other general plumber I’ve had come out to check the same issue. Jackson went above and beyond to ensure I fully understood the situation and all possible solutions, making me feel confident in making the right choice for my home. His professionalism, expertise, and attention to detail far exceeded my expectations.

Tankless Water Heater Repair Services FAQs

We’re here to make things simple. Below are answers to some of the most common questions we get from Utah homeowners.

Common warning signs include lukewarm or fluctuating water temperatures, recurring error codes or warning lights, strange noises, leaks around the unit, low hot water pressure, or no hot water at all. If you notice any of these, schedule professional tankless water heater repair before the problem gets worse.

Tankless heaters combine gas, electricity, venting, and advanced electronics. DIY work can lead to gas leaks, carbon monoxide issues, electrical hazards, or voided warranties. Licensed technicians use proper diagnostic tools, follow Utah codes, and repair according to manufacturer guidelines, keeping your home, family, and investment protected.

First, a technician inspects your tankless system, checking error codes, gas supply, venting, filters, flow rates, and the heat exchanger. They explain what failed, provide upfront pricing, then complete repairs with stocked parts when possible. Finally, they test multiple fixtures, verify stable temperatures, and optimize performance.

Because Utah has hard water and cold winters, most homes benefit from annual professional maintenance. Service typically includes descaling the heat exchanger, cleaning filters, checking gas and water connections, and testing safety controls. Homes with high usage or no softener may need more frequent descaling to maintain efficiency.

Costs vary based on the issue, brand, and whether emergency service is needed. Minor sensor or flush-related repairs can be relatively affordable, while heat exchanger, control board, or gas-line problems cost more. Reputable companies provide on-site diagnostics and upfront, written pricing so you know the cost before work begins.

Replacement is often smarter when the unit is older, out of warranty, repeatedly breaking down, badly scaled from hard water, or incorrectly sized for your home. If major components fail, repair costs can approach a new system. A licensed pro can compare repair vs. replacement based on your situation.
