What sets our tankless installation apart.

01

Modern Technology That Saves Money

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

02

Proper Sizing & Positioning

Installation is not just mounting a unit on a wall. We assess your home's plumbing layout, hot water demand based on how many showers and appliances run at once, and venting requirements to recommend the right capacity. A system that is too small underperforms; one that is oversized wastes money.

03

Navien & Rinnai Expertise

We are 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 explain the trade-offs so you pick the system that fits your priorities, not just the lowest price.

04

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 confirm your water pressure and flow rates work with the system.

05

Protects Existing Plumbing

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

Local Water & Climate Knowledge

Our service areas span Longwood, Celebration, Orlando, The Villages, and beyond. We understand 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, we are nearby and respond fast.

// Tankless installation FAQ

Questions Central Florida asks.

Straight answers, no upsell, no runaround.

How long does a tankless water heater installation take?

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

What is the difference between condensing and non-condensing units?

Condensing models, at 90 percent-plus efficiency, 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.

What size tankless water heater do I need?

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

Does my gas line need to be upgraded for a tankless system?

Often yes. Tankless systems require more gas flow than tank water heaters, so we inspect your existing gas line during assessment. If it is undersized, we recommend an upgrade and explain the cost before proceeding, so there are no surprises on installation day.

Will a tankless water heater save money on my energy bill?

Yes. Most customers see 20 to 40 percent 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.

How long until hot water reaches my bathroom faucet?

That depends on distance from the unit to the faucet. For the first 10 to 30 seconds you 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.
