Most homeowners look into tankless water heaters after hitting the same problem a few times. Hot water runs out during back-to-back showers. Someone starts laundry and everything goes cold. Or the old tank takes up space and still struggles to keep up.

That’s usually when people start asking if tankless makes sense for their home.

Limric’s tankless water heater installers help Charleston homeowners figure that out before anything gets installed. Tankless systems work well, but only when they’re sized correctly and set up for how the house actually uses hot water. That’s where most problems start when installations go wrong.

Benefits of Tankless Water Heaters When Installed Correctly

Tankless water heaters get a lot of attention for good reasons, but the benefits depend on proper installation.

When the system is sized and installed the right way, homeowners usually notice:

Hot water that doesn’t run out during normal use
Lower energy use compared to constantly reheating a tank
More usable space where the old tank used to sit
Fewer temperature swings at fixtures

Tankless systems also tend to last longer than tank units, but only when maintenance is kept up.

How Tankless Water Heaters Actually Work

Tankless water heaters don’t store hot water in a tank. Instead, they produce hot
tankless water on demand. When you turn on a faucet or start a shower, water begins flowing
through the unit, a flow sensor signals the system, and the heat exchanger warms the water as it passes through. That’s why tankless water can feel “instant.” You are not waiting for a tank to reheat or refill.

Because there’s no stored supply, the water heater can only heat as much water as it can process
at once. If demand in your home goes beyond what the unit is sized for, such as multiple showers, laundry, and a dishwasher running, the tankless water temperature can drop. That’s also why sizing matters more than brand or extra features. A properly sized system helps ensure your water heater delivers steady hot water across your home without performance dips.

What to Expect During Your Tankless Water Heater Installation

A tankless installation starts with understanding your home, not the equipment.

During the installation process, we look at:

How many bathrooms the home has
Which fixtures are used at the same time
Existing plumbing and venting
Gas or electrical capacity
Space for the new unit

From there, the installation includes:

Clear pricing before work starts
Removal of the old water heater
Installation of the new tankless system
Code-compliant connections and venting
Testing to confirm proper operation

Most installations are completed in one day.

Tankless Water Heater Maintenance and Repair

Tankless systems still need service. Mineral buildup is common in Charleston, and it can affect performance if it isn’t addressed.

Limric provides:

Routine flush services
Performance checks and diagnostics
Repair for existing tankless systems
Emergency service when the system stops working

Skipping maintenance is one of the fastest ways to shorten the life of a tankless unit.

Common Questions About Tankless Water Heater Installation

How long does it take to install a tankless water heater?

Most installs are finished in one day. Some homes need upgrades that can extend the timeline slightly.

Can I replace my tank system with tankless?

Yes, but the home needs to be evaluated first. Gas, electrical, and plumbing capacity all matter.

What size tankless water heater do I need?

For Charleston, SC homes, the right size for tankless water heaters depends on how many fixtures
you run at once, not square footage. In many Lowcountry households, mornings can stack demand quickly. Two showers, a kitchen sink, and laundry running at the same time can push hot water demand beyond what a single unit can heat as it produces tankless water on demand. If the unit is undersized, temperature and flow performance can drop.

LimRic’s tankless water heater installers evaluate your home’s hot water habits, fixture count, and the
temperature rise needed for steady tankless water. We also check gas capacity if you are considering gas tankless, plus venting, placement, and other installation requirements. Correct sizing helps keep pricing and overall cost aligned with your needs, so the unit is properly installed and delivers consistent hot water throughout your home with fewer unexpected service calls.

Are tankless water heaters more efficient?

Yes. Tankless water heaters can be more efficient because they heat water only when you need it,
instead of keeping a tank of water hot all day. That can reduce wasted energy compared to traditional tank water heaters, which often reheat stored hot water throughout the day.

Efficiency depends on correct installation and routine maintenance. Charleston-area water conditions can contribute to buildup over time, which is why regular service matters. LimRic’s team handles the full job, from selecting the right unit to completing the work and answering common questions. If you ever need repair, we can troubleshoot quickly. If you are considering replacement, we will help you choose the best approach for a dependable water heater installation in your Charleston, SC home.
