What are common signs my hot water unit needs to be replaced?

Look for signs that indicate you need to replace your hot water unit. Though these symptoms can’t be conclusive, professional plumbers like us should be consulted to correctly diagnose your situation and determine if repairs are still a viable option.

The Age

Knowing when to replace your hot water unit can be challenging. However, it is a good idea to consider the age of the unit when deciding whether to replace it or not. Generally, most units have an expected lifespan of 10-15 years depending on type, quality and usage. When your unit surpasses this range it may become more prone to breakdowns, inefficiencies and even potential safety risks. Consequently, it is recommended to replace your system before reaching that point or as soon as you spot signs of wear and tear. If you are staying around the approximated timeline then a replacement might be in order.

Increased Consumption

Beware of noticeably higher utility bills and environmental footprint, as they can be signs that your hot water unit is losing its efficiency due to age and wear. Keep an eye on your energy and water usage regularly, and ensure it stays in line with the manufacturer’s standards. If you detect a major increase in consumption, it’s probably time to replace your hot water unit with a more energy-efficient model that saves on resources.

Volume Loss

If your hot water unit isn’t providing enough or runs out too quickly, it may be time for a change. Poor volume, affected pressure and temperature all contribute to uncomfortable showers and baths. When selecting a new unit, make sure it meets your household needs and the size of the space. Plus, don’t forget regular maintenance to avoid sediment buildup, leaks or damage – this will ensure you can take full advantage of your hot water!


Rusted pipes, corroded valves, or broken fittings are warning signs that your hot water unit needs to be replaced. Corrosion can cause your water to have a metallic taste, smell, or color which could be hazardous for you and your appliances. Delaying necessary repairs can lead to expensive water damage and mold growth, as well as an increased risk of fire – all not worth the wait! Regular inspection of your unit is necessary to avoid any of these problems from occurring. Don’t let corrosion take away from your peace of mind; replace your hot water unit today and ensure you drink safe, clean water for years to come.

Water Discoloration

Water discoloration – such as brown, yellow, red, or black color – could be warning you that it’s time to replace your hot water unit. Rust, sediment, bacteria, or other contaminants may maintain this discoloration which can ultimately change the taste and smell of your water, not to mention the cleanliness of your dishes, clothing and fixtures. If left unchecked, corroding pipes or a failing system could also lead to worse consequences. Flushing your unit and its pipes can help prevent this; if the discoloration persists however then it would be best for you to consider replacing either the entire unit or some components.

Tank Noise

Unusual noises such as clanking, banging, clicking, gurgling, or popping coming from your hot water system can be a sign that it needs to be replaced. These sounds may point to sediment buildup and overheating which can threaten the performance, efficiency and even the safety of your unit. If this is happening in your home it can also be disruptive and annoying for you and your family! To avoid these issues, make sure that you follow the manufacturer’s instructions and drain the unit regularly to remove any debris or sediment build up. Additionally, you should adjust the temperature and pressure settings as instructed. If persistent tank noise persists or worsens though, it’s time to upgrade your unit!

Regular Maintenance

Frequent repairs, replacements, and services may be a sign that your hot water unit is old and worn out – it’s not worth investing in. If the price of regular maintenance starts to exceed half the cost of a new unit, you should seriously consider getting a replacement for better reliability. Maintenance costs range from $75 – $300+ per visit, and if it’s required more often than once annually then this is an especially strong indication that your current model needs replacing. Don’t let yourself be frustrated with constantly needing repairs – replace your hot water unit instead!

What are the options for replacing my hot water unit?

The main types of hot water heaters are:

  • Conventional water heaters: These come with a tank that holds 20 to 80 gallons of hot water, heated through natural gas, electricity, propane, or fuel oil. While these are a popular choice due to their low cost and installation ease, their energy consumption is high and the access to the hot water supply is limited. Additionally, the lifespan of these water heaters are short-lived with about 10 to 15 years on average – not to mention the need for regular maintenance services and the potential for leakage or burstage which can lead to costly water damage.
  • Tankless water heaters: These offer a range of benefits, from their energy efficiency and long life to an unlimited supply of hot water. There are also drawbacks to consider, such as their higher upfront cost, complicated installation process, and the dreaded cold-water sandwich effect if multiple faucets are opened at once. It’s also worth noting that tankless water heaters require consistently good water pressure and quality for them to work properly.
  • Heat pump water heaters: These are also known as hybrid water heaters that use electricity to move heat from one place to another instead of generating heat directly. They use a heat pump that extracts heat from the surrounding air and transfers it to the water in a tank. The advantages of heat pump water heaters are their very high energy efficiency, low operating cost, and reduced greenhouse gas emissions. The disadvantages are their high initial cost, large size, and dependence on ambient temperature. Heat pump water heaters also require a dedicated space with sufficient ventilation and may produce noise and cool air as byproducts.
  • Solar water heaters: These employ renewable, clean energy to provide hot water at a low cost. While installation costs can be high and performance may vary by weather and location, there are tax credits and other incentives that can help offset the expense. Back-up systems are necessary for cloudy days or when demand is particularly high.
  • Condensing water heaters: These are an energy-efficient, cost-effective option for heating water, as they utilize the heat from exhaust gases to preheat incoming cold water and store it in a tank. However, due to their complexity and installation requirements, as well as a higher initial cost, this type of heater can be daunting. Additionally, condensing units may corrode over time, requiring a special venting system and drainage in order to properly dissipate vapors. Though there is much to consider when making the switch to condensing water heaters, it ultimately pays off—not only with lower costs but in reduced greenhouse gas emissions too!
  • Point-of-use water heaters: These are small water heaters that are installed near the point of use, such as a sink, shower, or faucet. They heat water on demand using electricity or gas and deliver it directly to the fixture. The advantages of point-of-use water heaters are their fast and convenient hot water delivery, reduced heat loss, and space saving. The disadvantages are their limited hot water supply, high installation cost, and potential scalding risk. Point-of-use water heaters also require a separate unit for each fixture and may not be compatible with some plumbing systems.
  • Combination boiler: This is a type of water heater that also serves as a central heating system. It heats water on demand using gas or oil and distributes it to the radiators and faucets. The advantages of combination boilers are their compact size, high energy efficiency, and dual function. The disadvantages are their high initial cost, complex installation, and potential pressure drop when multiple taps are opened at the same time. Combination boilers also require regular servicing and may not be suitable for homes with low water pressure or high hot water demand.

What will a plumber do to replace my hot water unit?

Replacing a water heater is a complex and hazardous undertaking that needs careful planning and preparation. Royal Flush is here to help you tackle this challenge through our hot water replacement services -we make sure to handle it with great caution in order to avoid any damages or injuries due to the pressurized gas or electricity involved with water heaters.

  • Replacing your water heater can be a daunting task, so it pays have a deep understanding. Ensure the new model is energy efficient and meets capacity and installation needs. It’s essential that the dimensions, fuel type, and venting system of the new water heater match up with what you had before – this also helps ensure local compliance. With all that taken care of, you can sleep easy knowing your hot water will be ready to go!
  • Turn off the gas or electricity supply to the old water heater and disconnect the gas line or the power cord. Shut off the water supply and attach a hose to the drain valve. Open the valve and a nearby hot water faucet to drain the tank completely.
  • Disconnect the water pipes from the old water heater using a pipe wrench or a tubing cutter. Cut the vent pipe from the old water heater if it is not compatible with the new one. Use an appliance dolly with straps to wheel out the old water heater and dispose of it properly.
  • Place the new water heater in a drain pan and secure it to the wall or floor with seismic straps if required by code. Connect the water pipes to the new water heater using flexible hoses or copper tubing and fittings. Apply pipe dope or Teflon tape to the threaded connections and tighten them with a wrench. Check for leaks by turning on the water supply and opening a hot water faucet.
  • Connect the gas line or power cord to your new water heater, and turn on the supply. For gas pilot lights, follow the manufacturer’s instructions to light it up. With electric elements, wait for the tank to fill before turning on the power. Adjust the thermostat and test your hot water faucet to make sure it works properly.
  • Secure the new water heater’s vent pipe by attaching it and securing it with screws or clamps. Be sure the pipe is sloped up, obstructions-free, and with no leaks. If you’re using a power vent, plug it into an outlet and test its operation.
