What You Should Know About Tankless Water Heaters
Tankless water heaters have been taking the home improvement and plumbing world by storm over the past several years, and it’s easy to see why. These innovative units offer a modern alternative to the bulky, conventional tank water heaters most homeowners grew up with. But like any home upgrade, tankless systems come with both advantages and trade-offs worth understanding before you make the switch.
Below, we’ll break down how tankless water heaters work, the benefits they offer, the potential drawbacks, and what to consider before installing one in your home.
How Tankless Water Heaters Work
Unlike traditional water heaters that store and continuously heat a large tank of water, tankless units heat water on demand. When a faucet or valve is turned to the “on” position, the heater’s internal heating element activates instantly. Once the valve is turned off, the unit stops heating water right away. There’s no standing tank of hot water waiting to be used — and no energy spent keeping water hot when nobody needs it.
Space-Saving Design
One of the most noticeable benefits of a tankless water heater is its size. A large tankless unit can easily fit within a space just two feet square, extending less than a foot from the wall. Compare that to a conventional tank water heater, which typically requires a much larger dedicated footprint, and it’s clear why tankless systems are popular in homes where space is limited — such as smaller utility closets, garages, or condos.
The Benefits of Going Tankless
1. Compact, Flexible Installation
Because tankless units are so much smaller than older, bulkier models, they can be installed in tight spaces that simply wouldn’t accommodate a traditional tank. This flexibility makes them a great option for smaller homes or homes undergoing a full remodel where space planning matters.
2. Nearly Endless Hot Water
Since tankless units heat water as it flows rather than relying on a limited stored supply, they can provide a virtually endless stream of hot water. No more “lathered, rinsed, but not repeated” moments when the hot water runs out mid-shower — a common frustration with standard tank units, especially in busy households.
3. Lower Monthly Energy Bills
Because tankless water heaters only heat water when it’s actually needed, they avoid the standby energy loss that comes with keeping a full tank of water hot around the clock. Over time, this can translate into noticeable savings on your monthly power bill — one of the biggest reasons homeowners consider making the switch.
Potential Drawbacks to Consider
1. Simultaneous Hot Water Demand
Tankless systems are highly efficient, but they do have limits. If you’re running more than one shower at once, or running a shower and dishwasher simultaneously, you may notice a drop in hot water performance. Because all of that water needs to be heated at the same moment, the unit can struggle to keep up depending on its size and capacity.
2. Possible Electrical Upgrades
Depending on the size of the tankless unit you choose, installing one may require an electrical upgrade in your home. Larger units draw significantly more power than standard tank heaters. It’s important to consult with a licensed electrician, alongside your plumber, to determine exactly what your home will need before installation begins.
Tank vs. Tankless: Which Is Right for You?
Deciding between a traditional tank water heater and a tankless system depends largely on your household’s habits and needs. Consider the following:
- Household size: Larger households with multiple simultaneous hot water demands may need a larger tankless unit or should carefully evaluate their usage patterns.
- Available space: If you’re tight on space, a tankless system’s compact footprint is a major advantage.
- Long-term energy costs: If lowering your monthly utility bill is a priority, the efficiency of a tankless unit may pay for itself over time.
- Upfront investment: Tankless units typically cost more upfront than traditional tanks, including potential electrical upgrades, so it’s worth weighing the long-term savings against the initial investment.
A licensed plumber can help you evaluate your household’s hot water usage and recommend the right size and type of unit for your specific situation.
Maintaining Your Tankless Water Heater
Like any water heater, tankless systems benefit from regular maintenance to keep them running efficiently for years to come. Recommended upkeep includes:
- Periodic flushing to remove mineral buildup and sediment
- Annual inspection of the heating element and connections
- Checking for error codes or performance changes over time
Homes with hard water may benefit from pairing a tankless unit with a water softener installation, which helps reduce mineral buildup that can shorten the lifespan of your unit. A Halo whole-home water filtration system can offer similar protection while also improving water quality throughout your home.
Frequently Asked Questions
Do tankless water heaters really save money?
Yes, in most cases. Because they only heat water on demand rather than maintaining a hot tank around the clock, tankless units typically use less energy over time, which can lower monthly utility bills.
How long do tankless water heaters last?
With proper maintenance, tankless water heaters can last significantly longer than traditional tank units — often 20 years or more, compared to 8-12 years for a standard tank.
Is a tankless water heater a good fit for a large family?
It can be, but sizing matters. Larger households with high simultaneous hot water demand may need a larger unit or multiple units to avoid performance issues during peak usage times.
