Keep Your Tankless Water Heater Performing at Its Best
Ark Plumbing & Heating provides expert tankless water heater service and repair across the Township and City of Langley. Tankless systems are designed to deliver endless hot water on demand, but they're not maintenance-free — mineral buildup from Langley's water supply, ignition issues, and fluctuating temperatures are all common problems that reduce efficiency, increase energy costs, and shorten the lifespan of your unit. Whether you have a tankless system in a newer Willoughby townhome, a retrofit unit replacing an old tank in your Murrayville rancher, or a high-output model serving a larger Brookswood property, our licensed technicians diagnose issues quickly and get your hot water flowing again — with upfront pricing, honest assessments, and repairs done right the first time.

Our Tankless Water Heater Services for Langley Homes
Annual Descaling & Flushing
Mineral deposits gradually accumulate inside your tankless unit, coating the heat exchanger and reducing its ability to transfer heat efficiently. Left unchecked, this buildup forces your system to work harder, drives up energy consumption, and can eventually cause component failure. Our technicians perform thorough descaling and flushing to clear mineral buildup and restore full heating performance. This is especially important for Langley properties in areas with harder water conditions — including parts of Aldergrove, Campbell Valley, and rural Township homes on well water — where scale accumulates faster than in homes connected to treated municipal supply. We recommend annual flushing at minimum to keep your tankless unit running efficiently and avoid premature breakdowns.
Diagnostics & Repair
From error codes and ignition failures to inconsistent water temperature, low flow output, and unusual noises, our team has the hands-on experience to troubleshoot and repair a wide range of tankless water heater problems. We work on all major brands common across Langley homes including Navien, Rinnai, Bosch, and Noritz, and carry commonly needed replacement parts so most repairs can be completed in a single visit. Whether your unit is struggling to keep up with demand in a busy Walnut Grove family home, throwing fault codes in your Yorkson townhome, or failing to ignite reliably in your Fort Langley heritage property, we find the root cause and fix it — not just reset the system and hope for the best.
Performance Tune-Ups & Safety Checks
A proper tankless tune-up goes well beyond flushing the system. Our technicians inspect venting and exhaust connections, test gas pressure and combustion levels, clean inlet filters, check for error history stored in the unit's diagnostics, and verify that all safety controls are operating within manufacturer specifications. For Langley homeowners with outdoor-mounted tankless units — common in newer Willoughby and Latimer builds where interior space is limited — we also check for weather-related wear, debris accumulation, and ensure freeze protection systems are functioning properly ahead of Langley's colder months. Regular tune-ups keep your unit running safely and efficiently, protect your manufacturer warranty, and help you avoid the cost and inconvenience of an unexpected cold water surprise.
