Why Central Florida Families Choose Us

Why Central Florida Families Choose Tankless Water Heater Installation With Us

From modern technology that saves money to expert installation that lasts decades.

Modern Technology That Saves Money

Tankless systems heat water only when you use it, eliminating the constant energy drain of keeping a 40–50 gallon tank hot around the clock. Our customers report 20–40% reduction in water heating costs after switching to tankless. That savings adds up fast, especially in homes with high hot water demand.

Calculate Your Savings

Proper Sizing & Positioning

Installation isn't just mounting a unit on a wall. We assess your home's plumbing layout, hot water demand (based on how many showers, appliances, and fixtures run simultaneously), and venting requirements to recommend the right capacity. A system that's too small will underperform; one that's oversized wastes money.

Schedule Assessment

Navien & Rinnai Expertise

We're authorized installers who understand the differences between these brands inside out. Navien excels in efficiency and outdoor temperature reset features; Rinnai is known for reliability and smart controls. We'll explain the trade-offs so you pick the system that fits your priorities, not just the lowest price.

Compare Brands

Technical Complexities Handled

Tankless systems require proper gas line sizing, condensate drainage for high-efficiency models, and venting that meets modern codes. We verify water quality before installation, discuss descaling maintenance to protect your investment, and ensure your water pressure and flow rates work with the system.

Technical Consultation

Protects Existing Plumbing

If you're replacing a tank water heater, we carefully disconnect and remove the old unit, check for corrosion or mineral buildup in your supply lines, and assess whether your home's plumbing needs any upgrades to support the higher flow demands of a tankless system.

Local Water & Climate Knowledge

Our service areas span Longwood, Celebration, Orlando, Miami, and beyond. We understand the regional water hardness (a factor in tankless maintenance), seasonal demand patterns, and the best venting approaches for Florida's humidity. When you need follow-up service or have questions, we're nearby and respond fast.

How We Install Your Tankless Water Heater: A Detailed Walkthrough

Our installation process combines careful planning, precise execution, and thorough testing. Here's exactly what happens from assessment to completion.

Site Visit & Hot Water Demand Assessment

We begin with a detailed conversation about your household's hot water use. How many people live in your home? Do you often run multiple hot water appliances at once (shower + washing machine + dishwasher)? Are there specific rooms in your home where hot water reaches slowly? We also inspect your current water heater setup—location, gas line, venting, and water supply.

This visit includes measuring the distance from your hot water source to the farthest fixture, counting simultaneous hot water demands, testing current water pressure and flow rate, and inspecting the gas supply line to confirm it's sized correctly for a tankless system.

What We Assess During Your Visit

  • Distance from hot water source to farthest fixture
  • Simultaneous hot water demands (showers, appliances)
  • Current water pressure and flow rate testing
  • Gas supply line sizing verification
  • Existing venting routes or new venting requirements
  • Water quality and descaling frequency assessment
  • Wall space and structural support evaluation
  • Whole-home vs. point-of-use system discussion
Schedule Site Visit

System Selection & Equipment Specification

Based on your demand profile, we recommend a tankless capacity (measured in GPM—gallons per minute) that covers your peak simultaneous use. Navien and Rinnai offer a range of sizes, from compact units delivering 6–8 GPM (suitable for a single bathroom) up to large whole-home systems handling 10+ GPM.

We explain efficiency trade-offs, technology features like smart thermostats and recirculation pumps, warranty and service coverage, and integration with other systems like whole home repiping or water filtration.

System Selection Factors

  • System capacity (GPM) matching household demand
  • Condensing vs. non-condensing efficiency comparison
  • Smart features and control options review
  • Warranty terms and registration requirements
  • Equipment delivery and installation scheduling
  • Integration with concurrent plumbing projects
  • Optional upgrades (recirculation pump, filtration)

Preparation & Removal of Old Equipment

On installation day, we arrive early and organize the work area. If you're replacing a tank water heater, we shut off gas and water supplies safely, drain the old tank completely, disconnect all lines and venting, and remove the old tank while cleaning the installation area.

We inspect exposed plumbing for corrosion, leaks, or mineral deposits—any issues we find now are cheaper to fix before your new system goes live. This is also when we check for potential slab leaks or water line issues.

Preparation Checklist

  • Shut off water and gas supplies safely
  • Drain old water heater fully and dispose responsibly
  • Disconnect all supply lines, drain lines, and venting
  • Remove old equipment and clean mounting area
  • Inspect plumbing for corrosion, mineral buildup, or damage
  • Verify gas line sizing adequacy for tankless systems
  • Check for code violations or safety concerns
  • Confirm new equipment matches specifications

Tankless Unit Installation, Venting & Line Connections

This is where precision matters. We securely mount the tankless unit on the wall, connect it to the water supply and return lines with isolation valves, attach the gas line with proper shutoff and regulator, and set up the venting system—either a concentric vent or separate pipes depending on your unit and location.

Installation includes wall mounting brackets with adequate structural support, connecting water supply lines with shutoff valves and sediment filters, gas line connections with pressure regulators, and proper venting setup with condensate drainage for high-efficiency models.

Installation Components

  • Wall mounting brackets with structural support verification
  • Water supply connections with shutoff valves and filters
  • Hot water line connections with isolation valves
  • Gas line connection with shutoff and pressure regulator
  • Venting system setup (PVC or metal depending on model)
  • Condensate drain line installation and slope verification
  • Pressure testing all connections at 80 PSI
  • Gas leak testing and pressure verification

Testing, Programming & Final Walkthrough

Before we leave, we thoroughly test your new system and walk you through every detail. We fire up the unit and run hot water at multiple fixtures simultaneously to confirm the unit reaches target temperature without shuttering, test the thermostat or smart control, and run the recirculation pump if installed.

We explain the digital display, walk through the descaling process, provide all manuals and warranty documentation, discuss seasonal adjustments, and schedule a follow-up visit to check pressure and performance within 30 days.

Final Testing & Documentation

  • System heating verification at set temperature
  • Multiple fixture simultaneous flow testing
  • Thermostat controls and smart app functionality
  • Error code explanation and troubleshooting guide
  • Descaling procedures and maintenance frequency
  • Complete documentation and warranty registration
  • Emergency shutdown procedures
  • 30-day follow-up pressure check scheduling

Tankless Water Heater Installation Questions Answered

Frequently Asked Questions About Tankless Water Heater Installation

Most installations take 4–6 hours, depending on whether you're replacing an existing tank and how extensive the gas line or venting modifications are. We'll provide a specific timeline during your assessment. Complex installs may take longer.

Sizing depends on your simultaneous hot water demand. A single bathroom might need 6–8 GPM, while a family of four with multiple bathrooms and a washing machine usually needs 10–14 GPM whole-home. We calculate this during our site visit by factoring in peak simultaneous usage, not guesses.

Yes, most customers see 20–40% energy savings because the system heats water only when you use it. Exact savings depend on your current usage and which system you choose. Gas tankless systems typically save more than electric models.

That depends on distance from the unit to the faucet. The first 10–30 seconds, you'll feel warm water traveling through the pipes. For distant bathrooms, we can install a recirculation pump to bring hot water to the fixture immediately, eliminating wait time.

Yes, descaling is important. If your water is hard, we recommend descaling every 6–12 months to prevent mineral buildup on the heat exchanger. Soft water requires less frequent descaling. We can enroll you in a maintenance plan that handles this automatically.

Condensing models (higher efficiency, 90%+) extract heat from exhaust gases and require plastic vent pipes and condensate drainage. Non-condensing models are simpler to install but less efficient. Condensing systems cost more upfront but save significantly on gas bills over time.

Yes, as long as you have proper venting and gas access. Garages work well because of easy venting. Basements require careful condensate drainage (especially for condensing units) and proper clearance from living spaces. We'll confirm the best location during your site visit.

Often yes. Tankless systems require more gas flow than tank water heaters, so we inspect your existing gas line during assessment. If it's undersized, we'll recommend an upgrade and explain the cost before proceeding.

Most modern units display an error code that tells us (or a technician) what's wrong. Common issues are mineral buildup, water pressure drops, or temperature sensing problems—all fixable. If you're a maintenance plan member, we respond quickly. Call us anytime at (407) 847-0884 for emergency service.

Yes, we work with financing partners to make your upgrade affordable. Contact us to discuss payment plans that fit your budget and get your system installed without delay.
