Frequently Asked Questions

What are signs that my water heater needs to be repaired?

Signs that your water heater may need repair include inadequate hot water supply, unusual noises such as banging or popping, visible leaks around the tank, discolored or foul-smelling water, fluctuating water temperatures, and a sudden increase in energy bills. Additionally, if you notice rust on the tank, corrosion on the burner or flue, or the pilot light frequently going out, these are indicators of potential issues. Regularly checking for these signs and addressing them promptly can help prevent more extensive damage and ensure the continued efficient operation of your water heater. If in doubt, consult with a professional plumber for a thorough inspection and necessary repairs.

Several reasons could contribute to issues with hot water not working or not being hot enough. It could be due to a malfunctioning heating element, a faulty thermostat, sediment buildup in the tank affecting heating efficiency, a tripped circuit breaker or blown fuse, or issues with the gas supply (for gas water heaters). Check the thermostat settings, inspect for visible leaks, and ensure the pilot light is lit (for gas heaters). If you’re unable to identify or fix the issue, it’s advisable to consult with a professional plumber to diagnose and address the specific problem, ensuring your hot water system functions properly.

A leaky hot water heater can be potentially dangerous. Water leaking from the tank can cause structural damage to the surrounding area, leading to mold growth, deterioration of walls or flooring, and other issues. Moreover, a leak might be a sign of a failing pressure relief valve, which could result in excessive pressure within the tank, presenting a risk of explosion. Additionally, if the water heater is a gas unit, a leak could lead to gas buildup, posing a safety hazard. It’s crucial to address any leaks promptly, assess the cause, and seek professional assistance to ensure the safe operation of the water heater and prevent potential risks.

Several signs may indicate that it’s time to replace your hot water heater. If you frequently experience inadequate hot water, notice rusty or discolored water, observe leaks around the tank, or hear unusual noises, these can be indications of a failing unit. Additionally, if the water heater is more than 10-15 years old, its efficiency may decline, making replacement a wise choice for energy savings. Increased energy bills, visible corrosion on the tank or components, and the need for frequent repairs are also factors suggesting replacement. When in doubt, call Radiant Plumbing and Air for an assessment can help you determine whether it’s time to replace your hot water heater.

Yes, many plumbers are qualified to install boilers. Boiler installation involves intricate plumbing work, including connecting to the water supply, installing distribution piping for heated water, and ensuring a secure connection to the gas line or another fuel source. It’s crucial to choose a qualified and experienced plumber familiar with boiler installations, given the specific requirements and safety considerations involved. Our team at Radiant Plumbing is not only licensed but also extensively trained in boiler installations, ensuring precision, efficiency, and compliance with local building codes. When considering a boiler installation, trust our expertise and credentials. Contact us today for a reliable and expert service tailored to your needs.

The expense associated with replacing a water heater is subject to various factors, such as the type of unit, its capacity, local labor rates, and any additional plumbing necessities. On average, installing a standard 40-50 gallon gas or electric water heater may incur costs ranging from $800 to $1,500, encompassing both the unit and installation. For tankless water heaters, known for their complexity, the cost could escalate to anywhere between $2,000 and $5,000 or more. It’s crucial to note that these figures are general approximations, and actual prices may significantly differ based on your geographical location and specific requirements. Reach out to Radiant Plumbing and Air, and not only will we ensure the selection of the right water heater for your home, but we’ll also strive to secure the most budget-friendly option, inclusive of any applicable Texas or national rebates.
