Benefits of Tankless Water Heaters

Tankless systems provide efficient hot water delivery while taking up less space than traditional tank-style units. Many Jacksonville homeowners choose these systems for improved performance and long-term energy savings.

  • Continuous Hot Water Supply: Tankless systems heat water as it flows through the unit, helping prevent cold showers during heavy household use.
  • Lower Energy Costs: On-demand water heaters operate only when hot water is needed instead of constantly reheating stored water.
  • Compact Design: Wall-mounted systems free up space in garages, utility rooms, and storage areas.
  • Long Equipment Lifespan: Properly maintained tankless water heaters often last longer than conventional tank models.
  • Reduced Risk Of Tank Leaks: Without a large storage tank, homeowners avoid the risk of major tank-related water damage.

Is an Instant Water Heater Right for Your Home?

Tankless hot water heater installation starts with evaluating your home’s water usage, plumbing layout, and fuel source. Proper sizing is important because undersized systems may struggle to meet household demand, while oversized systems can create unnecessary operating costs.

Lickety Split AC, Plumbing & Electric installs gas and electric tankless water heaters from trusted manufacturers, including Navien, Rinnai, Noritz, Rheem, and Bosch. Our technicians help homeowners select systems based on family size, fixture usage, and efficiency goals.

Tankless systems are popular in Jacksonville homes because they work well for:

  • Larger households with high hot water demand
  • Homes looking to improve energy efficiency
  • Property renovations and remodeling projects
  • Smaller utility spaces
  • Vacation homes and guest suites
  • Homeowners replacing aging storage tank systems

If your current instant water heater struggles to maintain temperature, produces error codes, leaks, or shuts down unexpectedly, our technicians can diagnose the issue and complete the necessary repairs. We service many common tankless water heater problems, including ignition failures, mineral buildup, sensor malfunctions, venting issues, and flow sensor problems.

Homeowners dealing with plumbing system concerns may also benefit from scheduling professional plumbing services to inspect connected fixtures and water lines.

Tankless Water Heater Installation

Installing a continuous water heater requires careful attention to gas lines, venting, electrical requirements, and water flow rates. Our technicians ensure every installation meets manufacturer specifications and local code requirements for safe operation.

For homeowners upgrading from traditional tank systems, tankless water heaters can provide more consistent hot water while reducing standby energy loss.

Tankless Water Heater Repair

Even high-efficiency systems require occasional service. Jacksonville’s water conditions can contribute to mineral buildup inside tankless units, especially when maintenance is neglected. Prompt repairs help restore performance and reduce strain on system components.

If your system experiences fluctuating temperatures, delayed hot water delivery, or repeated shutdowns, our team can identify the source of the problem and recommend the appropriate repair solution.

Tankless Water Heater Cleaning & Descaling

Routine maintenance plays a major role in the performance and lifespan of tankless water heaters. Mineral deposits from hard water can accumulate inside the heat exchanger over time, restricting water flow and reducing heating efficiency.

Tankless water heater cleaning and descaling helps remove calcium and mineral buildup before it causes larger operating issues. Regular descaling of tankless water heater systems can improve efficiency, maintain water pressure, and help prevent premature equipment wear.

Many manufacturers recommend professional flushing and cleaning at least once per year, especially in areas where mineral content in the water supply is higher.


Lickety Split AC, Plumbing & Electric provides professional tankless water heater installation, repair, and maintenance for homeowners across Jacksonville, FL. Our team focuses on reliable workmanship, honest recommendations, and responsive service.
