What Is a Tankless Water Heater?

Tankless (on-demand) water heaters heat water only when you need it, so you’re not paying to keep 40–80 gallons hot all day. Many homeowners choose tankless for longer equipment life, space savings, and consistent hot water for back-to-back showers.

Benefits of Tankless Water Heaters

• Endless hot water (properly sized)
• Higher efficiency vs. standard tanks
• Wall-mounted, space-saving design
• Longer lifespan with proper maintenance
• Great option for busy households and cabins/seasonal homes

Tankless Water Heater Installation (Gas or Electric)

A proper tankless install is more than swapping units. We verify sizing, fuel type, venting, gas line capacity (for gas models), electrical requirements (for electric models), water quality considerations, and safe code-compliant installation.

What’s Included in a Professional Install

• Sizing based on household demand (showers, laundry, dishwasher)
• Removal of old unit (if replacing)
• Mounting, piping, shutoffs, and isolation valves (important for maintenance)
• Venting/condensate routing (as required)
• Startup testing, safety checks, and homeowner walkthrough

Quick guide:
• 1 bath / light use: smaller capacity
• 2–3 baths: mid to higher capacity
• Large household / multiple simultaneous showers: high capacity or multiple units

How to Choose the Right Tankless Size

Tankless units are sized by flow rate (GPM) and temperature rise. If a unit is undersized, you’ll get lukewarm water during simultaneous use. We’ll recommend the right capacity based on the number of bathrooms, fixtures, and typical simultaneous hot water usage.

Tankless Water Heater Repair Near Me

If your tankless system shows an error code, runs cold, fluctuates in temperature, or has reduced flow, we can diagnose the cause and restore performance.

Common tankless repair issues:
• Mineral scale buildup (hard water) causing reduced heating
• Ignition/flame sensor issues (gas units)
• Venting/airflow problems
• Water flow sensor or inlet filter blockage
• Recirculation system issues
• Error codes and intermittent shutdowns

Tankless Water Heater Maintenance (Descaling / Flush Service)

Tankless units need periodic descaling to remove mineral buildup—especially in areas with harder water. Regular maintenance helps maintain efficiency, protect internal components, and prevent nuisance error codes.

What Maintenance Typically Includes

• Descale/flush (frequency depends on water quality and usage)
• Clean inlet filter
• Inspect venting and combustion (gas models)
• Check for leaks, flow issues, and performance

Tankless Water Heater FAQs
Is a tankless water heater worth it in Michigan? +
For many homes, yes. Tankless units can be more energy efficient than traditional tanks and provide consistent hot water when properly sized. They also save space and typically last longer with routine maintenance. We’ll help you compare options based on your home, usage, and budget.
How long does installation take? +
Many tankless water heater installations can be completed in a day. Timing depends on whether you’re replacing an existing unit, upgrading gas/electrical capacity, and venting or plumbing adjustments needed. We’ll confirm scope and timeline after an assessment.
How often should a tankless water heater be flushed/descaled? +
Most manufacturers recommend flushing at least once per year. If your area has harder water, more frequent descaling may be needed to prevent mineral buildup that can reduce performance and efficiency.
Why does my tankless water heater go cold mid-shower? +
Common causes include mineral scale buildup, restricted flow from a clogged inlet filter, ignition or sensor issues (gas units), or demand exceeding the unit’s capacity. We can diagnose the issue, clear blockages, and restore consistent hot water.
Do tankless units work well with hard water? +
Yes, but maintenance matters. Hard water can cause scale buildup inside a tankless heat exchanger, which is why regular flushing/descaling and cleaning the inlet filter are important. In some cases, a water treatment solution can also help protect the system.
Gas vs. electric tankless—what’s better for my home? +
Gas tankless units typically deliver higher flow rates for whole-home use, while electric tankless can be a good fit for smaller homes, point-of-use applications, or where gas isn’t available. We’ll recommend the best option based on hot water demand, existing utilities, and installation requirements.
What maintenance is required each year? +
Annual service typically includes a flush/descale, cleaning the inlet filter, checking for leaks, verifying temperature settings, and inspecting venting/combustion components on gas units. Routine maintenance helps prevent breakdowns and keeps efficiency high.
Do you offer emergency tankless repair? +
Yes. If you’re without hot water or your unit is showing error codes or shutting down, contact Rite Choice to schedule service as quickly as possible.
