Why Install a Tankless Water Heater?
When it’s time to install or replace a water heater, one type of water heater to consider installing is a tankless water heater. Tankless water heaters have several advantages over conventional storage tank water heaters. This guide will discuss tankless water heaters, the benefits of installing a tankless water heater, and signs indicating that an old water heater needs replacement.
What Is a Tankless Water Heater and How Does It Work?
A tankless water heater, also known as a demand-type water heater, is a type of water heater that heats water only when it's needed, unlike traditional storage water heaters that continuously heat and store water in a large tank. This fundamental difference means tankless units eliminate standby heat loss, a common inefficiency in conventional systems where stored hot water gradually cools down, requiring re-heating. Beyond energy savings, not having to heat stored water continuously allows tankless water heaters to be more compact in size.
When hot water is needed in a home with a tankless water heating system, cold water travels through a pipe into the unit. Inside the tankless heater, a powerful heating element (either gas or electric) rapidly heats the water to the desired temperature as it flows through. This heated water is then delivered directly to the faucet or fixture, providing a continuous supply of hot water. The system's ability to heat water on demand means there's no limit to the amount of hot water available, as long as the flow rate is within the unit's capacity. When the fixture is turned off, the heating process stops, conserving energy.
Benefits of Installing a Tankless Water Heater
One of the most compelling reasons to switch to a tankless water heater is the significant energy efficiency it offers. Unlike traditional tank-based systems that constantly heat and reheat a large volume of water in their tank, tankless units only activate when hot water is needed. This prevents energy waste, leading to lower utility bills.
Tankless water heaters are also able to provide a more continuous supply of hot water, which is a stark contrast to storage water heaters, where once the tank is depleted, the household has to wait for it to refill and reheat. Their compact size is another significant advantage of tankless water heaters, freeing up valuable space in utility closets, basements, or garages.
Tankless units also have a longer lifespan than conventional storage water heaters, often lasting 20 years with proper maintenance, compared to the 10 to 15-year lifespan for storage tank models. This longevity, combined with their energy efficiency and endless hot water supply, makes them a wise long-term investment for homeowners.
Signs It's Time to Replace an Old Water Heater
Recognizing the signs that the household’s existing water heater is nearing the end of its life allows for a water heater replacement before issues like unexpected cold showers and leaks arise. One of the most obvious indicators is its age. Most conventional storage water heaters have a lifespan of 10 to 15 years. If the unit is within this age range or older, it's time to consider replacement.
Lukewarm or insufficient hot water is another clear sign that the unit is struggling to perform and may need replacement. Visible rust or corrosion or signs of a corroded water heater, such as discolored and rusty-looking hot water, are also signs to replace the water heater, as is a leaking water heater.
If homeowners notice these signs, it's time to act. A plumber can inspect the unit to determine if it needs to be replaced. When it comes to installing a new water heater to replace an old one, homeowners should strongly consider a tankless water heater. As discussed, these units offer superior energy efficiency, virtually endless hot water, and a longer lifespan, making them a great upgrade for many homes.
