Service Overview
Tankless Water Heater Maintenance With Clear Answers Before Work Begins
Your tankless water heater works hard every day, delivering hot water on demand without the standby energy waste of a traditional tank. But Orlando's hard water is tough on heat exchangers — mineral scale builds up quietly, reducing efficiency, straining components, and shortening the life of a system you paid good money for. When maintenance slips, you start noticing the signs: longer waits for hot water, inconsistent temperatures, error codes you can't explain.
Lapin Services has been keeping Central Florida's plumbing systems running right since 1958. Our licensed technicians flush and descale your heat exchanger, inspect every component, and test performance from end to end — so your tankless unit delivers the efficiency and reliability it was built for. One annual visit protects your investment and keeps your warranty intact. We make it easy: upfront pricing, convenient scheduling, and a team that explains everything in plain language before any work begins.
Problems We Solve
Common Tankless Water Heater Maintenance Problems We Fix
You do not have to diagnose the problem yourself. These are common issues we help confirm, explain, and repair.
Mineral Scale Buildup
Orlando's hard water deposits calcium and magnesium inside your heat exchanger over time, reducing heat transfer efficiency and making your unit work harder than it should. Annual descaling removes that buildup before it causes lasting damage.
Reduced Hot Water Output
Scale and sediment restrict water flow through the heat exchanger, cutting the volume of hot water your unit can produce at one time. Regular maintenance restores full flow and consistent output throughout your home.
Inconsistent Water Temperature
A dirty or partially blocked heat exchanger struggles to maintain a steady output temperature, leaving you with frustrating hot-and-cold swings mid-shower. Flushing and tuning the unit brings temperatures back to spec.
Error Codes and Nuisance Shutdowns
Most tankless units display fault codes when sensors detect overheating, flow problems, or ignition issues — all of which skipped maintenance can trigger. A certified technician can read, diagnose, and clear codes before a minor issue becomes a service call.
Premature Component Wear
Burners, sensors, filters, and valves wear faster when scale and debris go unaddressed. Routine maintenance catches worn parts early, so a small repair doesn't turn into a full unit replacement.
When to Call
Signs Your Water Heater Needs Professional Attention
If you notice any of these signs, call Lapin. We will find the cause and explain what needs to happen next.
Hot Water Takes Longer
If you're waiting noticeably longer for hot water to arrive at the tap, scale buildup may be reducing your unit's output capacity. This is one of the earliest signs that a maintenance visit is overdue.
Water Temperature Fluctuates
Inconsistent water temperature — especially swings from hot to lukewarm during use — often points to a heat exchanger that needs flushing or a sensor that needs calibration.
Error Code on the Display
Any fault code on your tankless unit's display panel is worth taking seriously. Many codes signal flow restrictions, ignition problems, or overheating that routine maintenance can resolve.
Higher Energy Bills
A scaled heat exchanger forces your unit to run longer and burn more fuel to reach the same output temperature. If your utility bills have crept up without a clear reason, your tankless system may be the cause.
It's Been Over a Year
Manufacturers recommend annual maintenance for tankless water heaters — and in Central Florida's hard-water environment, once a year is the minimum. If you can't remember your last service visit, it's time to schedule one.

FAQs
Tankless Water Heater Maintenance FAQs
How often should a tankless water heater be serviced in Orlando?
Most manufacturers recommend annual maintenance for tankless water heaters. In Central Florida, where hard water accelerates mineral scale buildup, once a year is the minimum — and some high-use households benefit from service every six months.
What does tankless water heater maintenance include?
A standard maintenance visit includes flushing and descaling the heat exchanger, cleaning the inlet filter screen, inspecting the burner assembly and igniter, checking venting for obstructions, testing the pressure relief valve, and verifying overall performance. We document everything and walk you through what we found.
How long does a maintenance visit take?
Most tankless water heater maintenance visits take one to two hours depending on the unit’s condition, size, and how long it has been since the last service. We’ll give you a realistic time estimate when you schedule.
Does skipping maintenance void my warranty?
Many tankless water heater manufacturers require documented annual maintenance to keep the warranty valid. Skipping service — or having it done by an unlicensed technician — can leave you without coverage if a major component fails.
Can I flush my tankless water heater myself?
Homeowners can perform basic filter cleaning, but a proper descaling flush requires a submersible pump, food-grade white vinegar or descaling solution, and the right procedure for your specific unit. Improper flushing can damage components or leave scale behind — a certified technician ensures the job is done right.
What causes scale buildup in a tankless water heater?
Orlando’s municipal and well water contains elevated levels of calcium and magnesium. When hard water is heated, these minerals precipitate out and coat the inside of the heat exchanger — reducing efficiency and restricting flow over time. Annual descaling removes the buildup before it causes damage.
My unit is showing an error code — is that a maintenance issue?
Many common error codes — including those related to flow rate, overheating, and ignition — are directly caused by scale buildup or a clogged filter that routine maintenance would have prevented. Give us a call and we can diagnose the code and determine whether a maintenance visit will resolve it.
Do you service all brands of tankless water heaters?
Yes — our licensed technicians are experienced with all major tankless brands, including Rinnai, Navien, Noritz, Rheem, Bradford White, and others. Call us at (407) 326-3367 and let us know your unit’s make and model when you schedule.
