Used to break down old gas and water connections and cut pipe to length. We keep separate wrenches for gas and water so there's no cross-contamination of pipe sealant.

What's included in a tankless water heater installation
Every install includes the unit, gas line work, venting, water connections, testing, and permit coordination when required.
Work order
Tankless Water Heater Installation- Unit and mounting: We supply and mount the tankless unit on your wall, with proper clearances from combustible materials and enough room to service the inlet filter and heat exchanger. Units come from Rheem, Navien, or Bradford White based on your sizing needs.
- Gas line installation: We run a dedicated gas line from the meter or propane regulator to the unit, sized for the BTU demand. Black iron or CSST, with a sediment trap and shutoff valve. Pressure-tested at 10 PSI before the gas goes back on.
- Vent installation: Stainless steel vent run through the wall or roof with correct clearances from windows, doors, and intake air. We follow manufacturer specs and Florida Building Code requirements for termination height and distance.
- Water connections: Hot and cold connections in copper or PEX, with isolation valves on both sides so the unit can be flushed without shutting off the whole house. Pressure gauge on the line to confirm no leaks before we leave.
- Testing and temperature setup: We purge air from the gas and water lines, fire the unit, and set outlet temperature to 120 degrees. Then we run every hot fixture at once to confirm the unit holds temperature under peak demand.
- Walkthrough and registration: We show you how to set the temperature, where the isolation valves are, and how to flush the unit annually.

Tankless water heater installation crestview FL: what the job involves
A tankless unit sized correctly gives you endless hot water and lasts two decades. Sized wrong, it throws codes and runs cold. We measure before we quote.
Tankless water heater installation crestview FL means replacing a 40- or 50-gallon tank with a wall-mounted unit that heats water on demand. We start by calculating your peak flow rate in gallons per minute, then match it to a unit from Rheem, Navien, or Bradford White. From there we run a dedicated gas line, install a stainless steel vent, sweat the copper or PEX connections, and pressure-test the whole system before we leave. Most installs take four to six hours.
Crestview homes built before 1990 often have undersized gas meters and 1/2-inch supply lines that won't feed a 199,000 BTU tankless unit. We check the meter and the existing pipe run first, because a unit that starves for gas throws error codes and shuts down mid-shower.
- What it is
- A wall-mounted unit that heats water on demand.
- When it helps
- When your tank runs out or rusts through.
- What you get
- Endless hot water and lower gas bills.
How our tankless installation process works
Every job follows the same five steps, from the first phone call to the final walkthrough.
Tools and methods we use on tankless installs
Each method answers a different question. Together they leave very little to guess.
For sweating copper water connections. We use lead-free solder and flux, and we pressure-test every joint before the wall goes back together.
We put a gauge on the gas line and the water line to confirm no leaks. Gas gets tested at 10 PSI for 15 minutes. Water gets tested at working pressure.
If we suspect a corroded or restricted water line feeding the unit, we run a camera to see the inside of the pipe. This tells us whether the line needs replacement before the new unit goes in.
Used to check for hidden leaks in the wall or slab near the water heater location. Finding a leak before install prevents callbacks and water damage.

How tankless installation works in Crestview specifically
Crestview sits on the Florida panhandle, and the water here is moderately hard, averaging 7 to 10 grains per gallon. That means descaling matters more than it does in softer-water markets.
Crestview Heights
Many homes here were built in the 1970s and 1980s with original galvanized pipe and 1/2-inch gas lines. We often need to upgrade the gas line and check water pressure before installing a tankless unit.
Brookside
Newer construction with 3/4-inch gas stubs already roughed in. Installs here are usually faster and don't require a meter upgrade.
Downtown Crestview
Older commercial and residential buildings with tight utility spaces. We often mount tankless units on exterior walls to avoid venting through historic roof structures.

PhotoTwin Hills family of five: tank to tankless
Before: A 50-gallon tank from 2014 was running out of hot water by the third morning shower. Sediment buildup had reduced capacity to about 35 gallons effective. The family was staggering shower times and still getting complaints.
After: We installed a 199,000 BTU Navien unit with a new 3/4-inch gas line and side-wall vent. Now three showers and a dishwasher run at once with no temperature drop.
Crestview Heights electric to propane conversion
Before: The homeowner wanted to get off electric and onto propane.
After: We ran a propane line from the existing regulator, set the unit for propane, and vented through the roof. Recovery is instant instead of 30 minutes.
Downtown Crestview restaurant lunch rush fix
Before: A commercial tank couldn't keep up with the dish station and three hand sinks during the 11 a.m. to 1 p.m. rush. Dish crew was waiting on hot water and falling behind on ticket times.
After: We installed two commercial tankless units in parallel with new gas lines and upgraded venting. Hot water never runs out during lunch. Ticket times improved and the owner stopped getting complaints.
Problems a tankless install solves for Crestview homes
Most people call us because something is already going wrong.
Running out of hot water mid-shower
A 40-gallon tank gives you about 15 minutes of hot water before it goes cold.
Old tank leaking or rusting out
Once a tank starts leaking, it's done. A slow drip can turn into a flood that damages drywall, flooring, and anything stored nearby.
High gas or electric bills from water heating
A traditional tank keeps 40 to 50 gallons hot 24 hours a day, even when you're asleep or at work.
No space for a tank in the utility room
A 50-gallon tank takes up roughly 9 square feet of floor space.
Why Crestview homeowners switch to tankless
A tankless unit changes how your house uses hot water.
Endless hot water
A properly sized tankless unit delivers 7 to 11 gallons per minute at a 35-degree rise.
Lower gas bills
Tankless units only fire when you open a hot tap.
20-year service life
A tank water heater lasts 8 to 12 years before the anode rod gives out and the bottom rusts through.
Reclaims floor space
A wall-mounted tankless unit frees up roughly 9 square feet of garage or utility closet floor.

What Crestview homeowners say about our tankless work
Our 12-year-old tank started leaking on a Sunday. I called Monday morning and they had a Navien unit in by Wednesday afternoon. They ran a new gas line from the meter and vented it through the side wall. No hot water issues since.
We had three quotes and Crestview Emerald Vale was the only one that actually measured our gas meter before quoting. Two others just gave a price over the phone. They found our meter was undersized and coordinated the upgrade with Okaloosa Gas. Took an extra week but the unit runs perfect. Worth the wait.
Switched from a 50-gallon electric tank to a propane tankless unit. They ran the gas line, set the regulator, and had us running hot water the same day. The installer showed me how to check the inlet filter and told me to call if the unit ever threw an error code.

Yes, if you plan to stay in the house more than five years. The break-even point usually lands around year six or seven. If you're selling next year, a tank replacement is the cheaper call.
A standard swap takes four to six hours. If we're running a new gas line from the meter, adding a vent through the roof, or upgrading from electric, plan on a full day, sometimes two. We schedule the gas inspection separately, and that usually happens within 48 hours of the install.
Yes. We install natural gas and propane tankless units from Rheem, Navien, and Bradford White. We check your meter capacity first, because a 199,000 BTU unit needs a 3/4-inch gas line and enough supply pressure. If your meter can't keep up, we coordinate the upgrade with Okaloosa Gas before install day.
