Basics of Water Heater Replacement to Know
Water heater replacement doesn't have to be stressful when homeowners know the signs it’s needed and call for a new water heater installation rather than waiting until it breaks down and being stuck without hot water. This guide will share some simple water heater replacement basics to know, including signs a new water heater is needed, the advantages of installing a new water heater to replace an old one, and the differences between electric and gas models.
Signs It's Time for Water Heater Replacement
Being able to recognize the warning signs that indicate water heater replacement is needed can help avoid unexpected cold showers, high utility bills, and potential water damage. One of the most telling signs is a rusted or corroded water heater. Besides being visible on the tank, homeowners may also be alerted to rust and corrosion by discolored or rusty-looking water coming from the hot water taps. This rusty appearance often signals internal corrosion of the hot water tank. There might also be a metallic smell when using hot water.
Age remains a reliable predictor of impending failure and the need for replacement. Typical water heaters last about 8-12 years, so if the unit is older than 10 years, it likely needs replacement. Water heaters also lose efficiency as they age, so high water heating costs could signal an old and inefficient unit in need of replacement. Additionally, when repair is needed frequently, there is insufficient hot water, or there is visible leaking around the unit, these signs also suggest that the water heater needs replacing.
Don't wait for complete failure before considering replacement. Proactive water heater installation not only prevents the inconvenience of suddenly losing hot water but also provides an opportunity to upgrade to a more energy-efficient model that better suits the household's needs and lowers utility bills. Modern units offer superior performance while consuming less energy than their aging counterparts.
Benefits of Replacing an Old Water Heater and Installing a New One
Water heater replacement and a new water heater installation offer immediate advantages that can impact daily comfort and long-term finances. A new water heater installation can dramatically improve energy efficiency, with a modern, high-efficiency water heater using 10-50% less energy than outdated models. Additionally, water heaters become more inefficient as they age, so this, combined with the fact that new water heaters come in even more efficient models, can dramatically save homeowners money on their utility bills.
A newly installed water heater will also be more reliable and have a lower risk of experiencing problems, preventing inconvenience and discomfort, and saving money on repair costs. A new system will also deliver hot water more consistently, with faster recovery times. Daily routines can become more pleasant with dependable hot water that meets the household's demands and without the aging unit's efficiency and performance issues.
Choosing Between Electric and Gas Water Heaters
When planning a water heater replacement or a new water heater installation, choosing between an electric or gas water heater is one of the most crucial decisions homeowners will face. Each type offers distinct advantages and disadvantages, so the best choice for a home is situational. The perfect choice depends on the household's needs and existing home infrastructure.
Electric water heaters shine in several key areas. For one, they cost less to install upfront than gas models. Safety is another major advantage of installing an electric water heater. Unlike gas water heaters, electric models eliminate combustion concerns and carbon monoxide risks.
Gas water heaters, however, also offer compelling benefits that often justify their higher initial cost and the need for a gas line. They heat water faster than electric units, making them ideal for larger households with a high hot water demand. A gas water heater can also cost less monthly in utility costs, as they are more energy efficient.
Before making a decision, consider the home's existing infrastructure. Converting from electric to gas requires proper gas line installation, which can add to the project cost. Conversely, switching from gas to electric might necessitate electrical panel upgrades to handle the increased electrical load. Professionals can help homeowners make the best decision for their home.
