Something we’ve noticed lately, and it’s not just anecdotal at this point, is how many Collierville homeowners have started asking about tankless water heaters specifically, rather than just calling because their old tank finally sprang a leak. It’s a shift we’ve seen build over the past couple of years, and once you dig into why, it makes a lot of sense for a town like Collierville with its mix of newer construction and established neighborhoods.
The Problem With Running Out of Hot Water
Anyone who’s lived with a traditional tank water heater in a busy household knows the routine. Someone runs a load of laundry, someone else jumps in the shower, and by the time a third person tries to wash dishes, the water coming out of the tap has gone from warm to lukewarm to flat out cold. It’s not a design flaw exactly, it’s just how a tank works. Once that stored hot water is used up, the system needs time to heat a fresh batch, and that recovery time can stretch to thirty minutes or more depending on the size of the tank and how much cold water it needs to bring up to temperature.
Tankless systems solve this in a fundamentally different way. Because they heat water as it flows through the unit rather than pulling from a limited stored supply, there’s no tank to run dry in the first place. As long as the unit is sized correctly for the household, hot water is available continuously, whether that’s the first shower of the morning or the fifth.
What’s Driving the Shift in Collierville
Part of it is simply word of mouth. Collierville is the kind of community where neighbors talk, and once a few households on a street switch to tankless and mention how much they like it, curiosity spreads. Part of it is also generational. A lot of the housing stock in Collierville includes homes built in the eighties and nineties that are now due for a water heater replacement anyway, which puts homeowners at a natural decision point where they’re already comparing tank versus tankless rather than just replacing like for like.
There’s also a practical angle tied to how families use their homes today. With more people working from home at least part of the week, hot water usage throughout the day looks different than it did when everyone left the house by eight in the morning and didn’t need hot water again until evening. Spread out usage across the day actually plays to a tankless system’s strengths, since it’s heating water as needed rather than maintaining a full tank around the clock regardless of whether anyone’s home to use it.
Space Savings for Newer Construction
Newer homes and additions in Collierville tend to have tighter utility closets and mechanical spaces than older construction, since square footage is increasingly prioritized for living space rather than storage. A traditional tank, especially a larger one sized for a bigger family, takes up a meaningful footprint. Tankless units mount to a wall and take up a fraction of the space, which matters when a homeowner is trying to squeeze a water heater, an HVAC air handler, and storage all into the same small utility area.
This has become a common conversation during new construction and remodeling projects specifically, where the extra square footage freed up by going tankless can be used for something else entirely.
Energy Efficiency and Rising Utility Costs
We touched on this in general terms before, but it’s worth being specific here. Collierville homeowners, like the rest of the Memphis area, have watched utility costs climb over the past couple of years as MLGW works through its infrastructure improvement plan. That’s not something a water heater choice can undo, but it does make the ongoing efficiency difference between tank and tankless systems feel more relevant than it might have felt when energy costs were lower across the board.
Because tankless units aren’t constantly reheating a full tank of water throughout the day, they generally use less energy overall to deliver the same amount of hot water a household actually uses. Over the life of the unit, that adds up to real savings, even accounting for the higher upfront installation cost compared to a standard tank system.
What Installation Day Looks Like
For homeowners considering the switch, the actual installation process is usually more straightforward than expected, though it does look a little different from a simple tank swap. Our technicians start by assessing the home’s existing gas line and electrical setup, since tankless units require more instantaneous power to heat water quickly compared to a tank system’s slower, steady approach. In some Collierville homes, particularly older ones, this means upgrading the gas line size to support the new unit properly.
Once that assessment is done, the actual installation typically takes a matter of hours rather than days for most residential setups. The old tank gets removed, the new tankless unit gets mounted, and any necessary line or venting adjustments get made before the system is tested and confirmed to be working correctly. Homeowners are usually back to normal hot water access the same day.
Is Tankless Right for Your Collierville Home
Every household is different, and the honest answer is that tankless isn’t automatically the right call for everyone. A smaller household with modest hot water needs and an already efficient tank system in good working order might not see enough benefit to justify switching before that system actually needs replacing. But for Collierville families dealing with recurring hot water shortages, planning a remodel, or simply due for a replacement anyway, it’s worth a real conversation rather than defaulting to whatever was already there.
Questions Collierville Homeowners Ask Us Most
Will a tankless unit work with my existing gas line? Sometimes, but not always. Older homes throughout Collierville, particularly ones built before the more recent waves of new construction, were often built with gas lines sized for appliances that don’t demand as much instantaneous energy as a tankless water heater does. Part of any honest tankless conversation includes an actual assessment of your home’s gas line, since that determines whether an upgrade is needed as part of the installation.
How much smaller is a tankless unit compared to a tank? Most tankless units mount directly to a wall and take up roughly the footprint of a small suitcase, compared to a standard tank that can be four feet tall and two feet across. For homeowners dealing with a cramped utility closet or trying to free up space for storage, that difference is often reason enough on its own to consider switching.
Does switching to tankless mean I’ll never run out of hot water again? As long as the unit is sized correctly for your household’s peak demand, meaning the busiest moments where several fixtures might run hot water at once, you shouldn’t experience the tank running dry the way a traditional system can. An undersized tankless unit can still struggle if too many fixtures run simultaneously, which is exactly why proper sizing during installation matters so much.
What Collierville Homeowners Should Expect Cost Wise
Pricing for a tankless conversion varies based on a handful of factors, including whether your home needs a gas line upgrade, the size and capacity of the unit your household needs, and whether the installation is a straightforward swap or involves more extensive work to relocate venting or plumbing. Homeowners considering the switch should expect to pay more upfront than they would for a simple tank replacement, but should also factor in the considerably longer expected lifespan of a tankless system, often twenty years or more compared to roughly a decade for a typical tank, along with the ongoing efficiency savings that show up on the monthly utility bill.
A straightforward, honest quote that accounts for your specific home rather than a generic estimate is the only reliable way to know what the full project will actually cost. We walk every Collierville homeowner through exactly what their installation would involve before any work begins, so there are no surprises partway through.
For Collierville families dealing with recurring hot water shortages, planning a remodel, or simply due for a replacement anyway, a switch to tankless is worth a real conversation rather than defaulting to whatever was already there. The right choice really comes down to how your household actually uses hot water day to day, not just what happens to be trending among neighbors on your street, and a technician who takes the time to ask about that will give you a far more useful answer than a quick estimate over the phone ever could.
If you’re weighing the switch, we’re happy to walk through your specific situation honestly, including what it would actually cost and whether the long term savings make sense for your household. Call Benny James Service Company at (901) 763-3600 to get a straightforward answer.
