Tankless Water Heater Repair Medway

Complete Water Heater Repair Coverage

We repair all types of water heaters in Medway homes. Traditional tank units, tankless systems, gas-powered, electric, and hybrid models. Each type has different components that can fail, and we stock parts for the most common repairs.

Tank water heaters often need heating element replacement, thermostat repair, or leak fixes. Tankless units typically require descaling, sensor cleaning, or gas valve service. We handle both emergency repairs and routine maintenance that prevent bigger problems.

Every repair comes with warranty protection on our work. If the same component fails again within the warranty period, we return and fix it at no additional charge. That’s how confident we are in the quality of our water heater repair work.

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 approaching these ages and having frequent problems, replacement often makes more financial sense than repeated repairs. However, newer units with single component failures are usually worth repairing. We’ll assess your specific situation and give you honest recommendations based on the repair cost versus remaining lifespan. Signs that point toward replacement include rusty water, multiple simultaneous failures, or repair costs exceeding 50% of a new unit’s price.
Electric water heaters most commonly lose hot water due to failed heating elements or tripped circuit breakers. Gas units typically stop heating when the pilot light goes out, the gas valve fails, or the thermocouple needs replacement. Tankless water heaters might shut down due to mineral buildup, clogged filters, or sensor malfunctions. Sometimes the issue is as simple as incorrect thermostat settings or a tripped safety switch. Our diagnostic process identifies the exact cause quickly, so you’re not paying for unnecessary parts or guesswork repairs.
Most water heater repairs take 1-3 hours depending on the problem and parts availability. Simple fixes like thermostat replacement or heating element swaps usually finish within an hour. More complex repairs involving gas components, leak fixes, or multiple part replacements can take 2-3 hours. We stock common repair parts on our trucks, so most jobs complete the same day. If we need to special order a part, we’ll explain the timeline upfront and can often provide temporary solutions to restore some hot water while waiting for parts.
We repair both tankless and traditional tank water heaters throughout Medway. Tankless units require different expertise and tools compared to tank systems. Common tankless repairs include descaling to remove mineral buildup, cleaning or replacing sensors, servicing gas valves, and fixing error code issues. We carry diagnostic equipment specifically for tankless systems and stock filters, sensors, and other components these units commonly need. Whether you have a Rinnai, Navien, Rheem, or other tankless brand, we have the training and parts to get it working properly again.
Turn off the power supply immediately – flip the circuit breaker for electric units or turn the gas valve to “off” for gas water heaters. Shut off the water supply using the valve on top of the unit. If water is actively leaking, try to contain it with towels or buckets to prevent property damage. Don’t attempt to repair leaks yourself, as water heaters operate under pressure and involve electrical or gas connections. Call us right away for emergency service. Small leaks from fittings can often be repaired, but tank leaks usually mean the unit needs replacement due to internal corrosion.
