The lifespan of a water heater typically ranges from 8 to 12 years, but it can vary based on factors like the type of heater, water quality, maintenance, and usage patterns. Tankless water heaters often have a longer lifespan compared to traditional tank-style heaters. Regular maintenance, such as flushing the tank and addressing any issues promptly, can help extend the life of your water heater. If your heater is nearing the end of its expected lifespan, Call Radiant and we can help find the right plan to get your replacement installed.

Water heaters, while generally equipped with safety features like pressure relief valves, have a rare but potential risk of explosion if these mechanisms fail. Factors such as a malfunctioning pressure relief valve, faulty thermostat, or sediment accumulation can lead to excessive pressure within the tank, causing a rupture. Regular maintenance, including flushing the tank, testing the pressure relief valve, and addressing malfunctions promptly, is crucial to mitigate the risk of explosions and ensure safe operation. Make sure you find a reliable professional like Radiant for thorough inspections and repairs if you have concerns about your hot water tank.
Whether your water heater is covered by a home warranty varies depending on the terms outlined in your contract. Home warranties typically include major systems and appliances, and this often extends to heating and plumbing components. To ascertain whether your water heater is covered, carefully review the contract, paying attention to any specific conditions or exclusions that may apply. If you’re contemplating a replacement, it’s wise to explore the details of your coverage. Radiant Plumbing can assist you in understanding your warranty terms and provide expert guidance if you’re considering replacing your water heater.

Choosing between an electric or gas water heater involves weighing various factors. Electric heaters offer simplicity and lower upfront costs, but they might be less energy-efficient, leading to higher operating expenses. Gas water heaters, while more energy-efficient and cost-effective in the long run, come with higher installation costs and potential venting complexities. The decision hinges on considerations like local utility costs, installation requirements, and personal preferences. Prioritizing regular maintenance and assessing factors like energy efficiency can optimize the performance of either type. Rest assured, with decades of experience, Radiant Plumbing and Air is your trusted partner for repairing, maintaining, and installing both electric and gas water heaters.

To ignite your gas water heater, start by turning off the gas supply and setting the temperature control to its lowest setting. Locate the pilot light panel, switch the control knob to “Pilot,” and use an ignition button or lighter to ignite the pilot flame. Hold the control knob for 30 seconds, release it, and then turn on the burner. Refer to your water heater’s manual for precise instructions. If you become uncertain or have concerns about how to light the pilot light of your water heater, Call Radiant today!

With over 20 years in the business, we have worked on nearly every type of hot water heater on the market. Our technicians can repair a range of water heaters, including traditional tanked, tankless, and gas water heaters for all the major brands like Rheem, Rinnai, and AO Smith.
