Tankless Water Heater Repair

All Water Heater Types Covered

Whether you have a traditional tank water heater or a modern tankless unit, you get the same thorough service. Tank units often need element replacements, thermostat repairs, or leak fixes, while tankless systems might need descaling, sensor adjustments, or component replacements.

Many Dedham homes have older water heaters that just need the right repair to keep running reliably for years. Others have newer tankless units that require specialized knowledge to diagnose and fix properly.

You get honest assessment of whether your unit is worth repairing based on its age, condition, and the cost of the fix. No one’s trying to sell you a new water heater when a simple repair will solve your problem and save you money.

How do I know if my water heater needs repair or replacement?

Age is the biggest factor – most tank water heaters last 8-12 years, while tankless units can go 15-20 years with proper maintenance. If your unit is relatively new and the repair cost is under half the price of replacement, repair usually makes sense. However, if you’re dealing with multiple issues, rusty water, or a unit that’s already past its expected lifespan, replacement might be the smarter investment. A good technician will walk you through the math and help you understand the long-term costs of each option.

What are the most common water heater problems in Dedham homes?

Sediment buildup is huge here because of our local water conditions – it reduces efficiency and can cause strange noises or inconsistent temperatures. Heating element failures are common in electric units, especially during winter when they’re working harder. Thermostat issues cause water that’s too hot, too cold, or unpredictable. For tankless units, mineral buildup clogs the system and triggers error codes. Older homes often have issues with corroded pipes connecting to the water heater, which can look like a water heater problem but actually needs different repairs.

How long does a typical water heater repair take?

Most repairs take 1-3 hours depending on what’s wrong and whether parts need to be ordered. Simple fixes like thermostat adjustments or heating element replacements can often be completed the same day. More complex issues might require ordering specific parts, especially for older or specialty units. Tankless water heater repairs sometimes take longer because of the diagnostic process, but many common problems can still be fixed in a single visit. The technician will give you a realistic timeframe upfront and let you know if they need to come back with parts.

Can I prevent future water heater problems with maintenance?

Absolutely. Annual maintenance catches small issues before they become expensive repairs or complete failures. This includes flushing sediment from tank units, checking and replacing anode rods, testing temperature and pressure relief valves, and inspecting connections for leaks. Tankless units need regular descaling to prevent mineral buildup that causes most of their problems. The Dempsey Comfort Club includes maintenance services that keep your water heater running efficiently and help you avoid emergency breakdowns. Most water heaters that get regular maintenance last significantly longer than those that are ignored until something breaks.

What should I do if my water heater is leaking?

Turn off the power (breaker for electric units, gas valve for gas units) and the water supply valve immediately. A small leak at a connection might just need tightening, but leaks from the tank itself usually mean replacement is needed. Don’t ignore even small leaks – they typically get worse quickly and can cause significant water damage. Move anything valuable away from the area and call for service right away. If there’s a lot of water, you might need to turn off the main water supply to your house. Taking photos of the leak location helps the technician prepare for the repair and can be useful for insurance if there’s water damage.

Why is my water heater making strange noises?

Popping or rumbling sounds usually mean sediment has built up at the bottom of your tank and is getting heated, which creates steam bubbles that pop as they rise. This reduces efficiency and can eventually damage the tank if not addressed. Whistling or screeching often indicates a valve issue or mineral buildup restricting water flow. Banging sounds might be “water hammer” from pipes, not the water heater itself. For tankless units, unusual noises often point to mineral buildup or a failing fan. Most noise issues can be resolved with maintenance like flushing the tank or descaling, but they shouldn’t be ignored since they usually indicate problems that will get worse over time.
