Signs You Need a New Water Heater
Water heaters are reliable and durable appliances, but they don’t last forever. You can expect a traditional water heater to last eight to 12 years and a tankless model to last up to 20 years, but a replacement will be needed sooner or later. If your water heater develops a fault or its tank becomes corroded, it may fail sooner. Here are some warning signs that could mean you need a new water heater:
- Running out of hot water
- Water that isn’t hot enough
- Rusty water
- Bad-smelling water
- Strange noises
- Pools of water
- Low water pressure
Choosing the Right Water Heater for Your Home
If your water heater has reached the end of its service life and needs to be replaced, you will need to consider your needs, budget, and fuel source when you choose a new model. You could choose a traditional water heater with a large tank or a tankless model. Tankless water heaters cost more, but they last twice as long as traditional models and provide endless hot water. It would also be a good idea to consider running costs when you choose a new water heater. Some inexpensive models consume a lot of energy, so they may end up costing you more in the long run. You will also need to choose a water heater that fits into the space you have available. If you run out of hot water often but don’t have enough room for a water heater with a 65- or 80-gallon tank, a tankless model could be a good option.

Tankless Water Heater Installation
Tankless water heaters cost a little more than traditional models, but they last twice as long, are easier to install, and use a lot less energy. According to the U.S. Department of Energy (DOE), tankless water heaters are up to 34% more energy efficient than water heaters with large tanks. That’s because they heat water only when you need them to. Pipe Wrench Home Services offers a complete tankless water heater installation and calibration service. Plus, we have electric, natural gas, and propane models to choose from.
Benefits of a New Water Heater
The chief benefit of installing a new water heater is the peace of mind that comes from knowing your home will have a reliable source of hot water for up to 20 years. You won’t have to worry about being without hot water because an old appliance broke down, and you won’t see any rusty water or notice any foul smells when you turn your faucets on. You should also have lower utility bills. Water heaters are much more efficient than they used to be, and tankless models are the most efficient of all.

Water Heater Replacement and Installation FAQs
What is the life expectancy of a water heater?
A water heater’s lifespan can depend on several factors, including the type of water heater, the energy source, the type of local water supply you have, and how well the unit is maintained.
On average, most conventional “tank style” water heaters last between 8 and 12 years but some can last up to 20 years with regular maintenance, particularly tankless models.
How do you know when a water heater needs to be replaced?
Although there are several factors to consider, it may be time to replace your water heater if it’s more than 10 years old, leaks from the tank or water lines, requires frequent repairs, if your water bills have increased significantly, if it delivers inconsistent water temperatures, or if any repair cost is more than 50% of the replacement cost.
If you need a new water heater, be sure to contact the plumbing experts at Pipe Wrench who will help simplify the replacement process by providing the best recommendations tailored to your home and needs.
Why do most water heaters fail?
Water heaters typically fail due to a combination of factors, including but not limited to old age, sediment buildup, tank or component corrosion, faulty heating elements, thermostat issues, faulty valves, and high-water pressure.
What size water heater do I need?
To determine the right size of conventional “tank style” water heater, you should consider your household size, typical hot water usage habits, and peak demand times when you typically use the most hot water.
- Home with 1–2 people – A 30–40 gallon tank is usually sufficient.
- Home with 2–3 people – A 40–50 gallon tank should work.
- Home with 3–4 people – A 50–60 gallon tank is recommended, particularly if you have substantial hot water needs.
- Home with 5+ people – A 60–80 gallon tank is often required regardless of hot water usage.
If you have a large family or have high hot water demands, a tankless water heater could be a better alternative over a conventional tank water heater. Although they don’t store water, they efficiently heat water on demand that can provide long-term cost savings, and near-unlimited hot water.
What should you consider before installing a new water heater?
Before installing a new water heater, you should consider several factors including the type or model (tankless or conventional storage tank), fuel source (natural gas or electricity), size (tanks range from 30–80 gallons), energy efficiency, and installation costs. You also should consider the size of your home, your family’s hot water needs and usage, and the available space needed to house your water heater.
Can I install a water heater myself?
Although you can technically install a water heater yourself, it’s highly recommended hiring a licensed professional plumber like the experts at Pipe Wrench for water heater installation, particularly for gas models. The installation process involves handling plumbing, electrical, and sometimes gas connections, all of which can be complicated, potentially dangerous, and must comply with local codes and safety standards.
