Most professional services offer warranties on their work, providing peace of mind. Read reviews and check references to find the best service in your area for reliable installation.
Repair or Replace?
Choosing between repairing and replacing a water heater depends on various factors, such as the age of the heater, the cost of repairs, and the severity of the issue. Below, we explore common problems and guidelines to decide whether to repair or replace your water heater.
Troubleshooting Common Issues
No Hot Water: If there’s no hot water, check the thermostat and heating elements in an electric water heater. Faulty elements or thermostats are common causes and are usually inexpensive to replace.
Leaking Tank: A leaking hot water tank often signals a severe problem. While small leaks from valves or connections can sometimes be repaired, a cold water tank with leaks usually mean replacement is necessary.
Strange Noises: Popping or rumbling sounds often indicate sediment build-up at the bottom of the tank. This can be resolved by flushing the tank, but if the noise persists, the heater may need more extensive repairs or replacement.
Water Quality Issues: Rusty or cloudy water can be due to corrosion inside the tank. This is a sign of a leak or an ageing tank that likely needs replacing before it fails entirely.
When to Repair Instead of Replace
Age of the Heater: Water heaters generally have a lifespan of 10-15 years. If your water heater tank is less than 8 years old and repair costs are reasonable, repairing it might be the better option.
Cost of Repairs: Consider the repair costs. If repairs are less than 50% of the cost of a new unit and the heater is relatively new, repairing is usually more economical.
DIY Repairs: Simple issues like replacing heating elements or thermostats can often be done by the homeowner, reducing costs significantly. Always ensure the power is off and follow safety guidelines carefully.
Energy Efficiency: Older models may be less energy-efficient. If a repair restores functionality and efficiency, it can delay the need for an expensive replacement.
Maintaining Your New Water Heater
Proper maintenance of your new water heater ensures longevity and optimises efficiency. This involves regular checks, minor upkeep, and practising specific techniques to prevent issues.
Routine Maintenance Tips
Routine maintenance is essential for the optimal performance of your water heater. First, it is important to inspect the temperature setting regularly. Keeping it at around 120°F (49°C) can prevent scalding and reduce energy usage. Second, every three to six months, drain a few gallons from the tank to remove sediment build-up. Sediment can cause the heater to work harder, increasing wear and tear.
Third, test the pressure release valve biannually. This involves lifting the pressure relief valve’s handle partway and letting it snap back. If water flows out, it’s working well. If not, it might need replacement. Fourth, inspect the anode rod annually. This rod attracts minerals and impurities, preventing corrosion inside the tank. Replace it if it’s more than half worn.
