Heat Exchanger Descaling in Londonderry
The heat exchanger in a tankless heater is a coil of small tubes that water races through while the burner fires. Hard water drops calcium and magnesium on those hot surfaces, narrowing the passages over time. We connect a submersible pump and hoses to the service valves and circulate descaling solution for 45 to 60 minutes. Then we flush with fresh water to rinse the system completely. Restored flow means more stable temperatures and fewer shutdowns.
Residential Tankless Water Heater Flushing in Londonderry
A large share of homes rely on private wells, and some wells carry naturally occurring arsenic, radon or iron that call for treatment. Hard water can lead to heavy mineral buildup in tankless water heaters. Our residential flushing service in Londonderry involves circulating a descaling solution through your unit's heat exchanger to remove calcium and magnesium deposits. This process brings back efficiency, prevents overheating and extends the life of your appliance, so your family gets continuous hot water without interruption.
Isolation Valve Kit Installation in Londonderry, NH
Some tankless heaters were installed without service valves, which makes proper flushing impossible. We install a set of isolation valves with purge ports on the hot and cold lines so future maintenance takes minutes. The kit also lets you shut off water to the heater without closing the main. It is a one-time upgrade that pays for itself in simpler service.

Frequently Asked Questions About Tankless Water Heater Maintenance in Londonderry
The cost of tankless water heater maintenance in Londonderry typically ranges from $150 to $300, depending on the unit's condition, age and brand. This usually includes flushing, descaling and a complete inspection. More extensive repairs or part replacements would be quoted separately after diagnosis.
Yes, regular maintenance is crucial for maintaining your tankless water heater's energy efficiency. Descaling removes mineral deposits that force the unit to work harder, using more energy to heat water. Clean components and proper calibration ensure your unit operates at its designed efficiency, saving you money on energy bills.
It is recommended to have your tankless water heater professionally serviced at least once a year. In areas with very hard water, or for heavy usage, more frequent maintenance, such as every six to nine months, might be worth it to prevent scale buildup and maintain efficiency.
A standard tankless water heater maintenance service, including flushing and inspection, typically takes 1 to 2 hours. The exact time can vary depending on the unit's condition, the amount of scale buildup and any unforeseen issues encountered during the service.
Rinnai shows LC codes, Navien may show E003 or E030 and Noritz often shows 90 or 99 when scale or airflow is a problem. These codes typically clear after proper cleaning.
Neglecting maintenance can lead to several problems, including reduced heating efficiency, higher utility bills, decreased hot water output and eventually, costly breakdowns. Mineral buildup can seriously restrict water flow and damage the heat exchanger, potentially leading to premature unit failure and expensive repairs or replacement.
No, routine maintenance, such as flushing and inspection, generally does not require a permit in Londonderry. Permits are usually only needed for new installations, major repairs that involve altering gas or water lines, or replacing an entire unit. We will advise if any permit is needed for complex repairs.
Tankless water heater maintenance focuses mainly on descaling the heat exchanger and checking electronic components for efficiency. Hot water tank maintenance usually involves flushing sediment from the bottom of the tank, checking the anode rod for corrosion and inspecting the pressure relief valve. Both aim to prolong life but address different system needs.
