Golf course home conversions and re-venting near Eldorado Parkway and Hillcrest Road.
Quick Answer
Frisco Tankless Water Heater Pros serves Plantation Resort in Frisco, Texas 75035. Built around the Plantation golf course starting in the late 1980s, this is the oldest housing stock in the ZIP, and nearly every conversion here requires new venting and gas branch upsizing. Call (972) 430-9024.
The area
Plantation Resort is built around the Plantation golf course in northeast Frisco, near Eldorado Parkway and Hillcrest Road. The course opened in 1988 as an eighteen-hole layout designed by Richard Ellis across more than 125 acres, with Champions Bermuda fairways, twenty sand bunkers and nine ponds, and the neighborhood grew alongside it.
Homes were delivered between roughly 1988 and 2002 in two sections, with approximately 300 homes in the first and around 1,500 in the second. They are executive-scale one- and two-story homes, generally 1,800 to a bit over 3,200 square feet, with up to five bedrooms and three-car garages, served by two amenity centers with pools, playgrounds, basketball and tennis.
Plantation Resort has the mature landscaping and walkable street pattern that come with thirty-plus years of settling, and it also has the oldest mechanical infrastructure in ZIP 75035. Those two things are related.
Local detail
A home built in 1992 in this neighborhood has now cycled through two or three storage tanks. The appliance keeps getting replaced but the infrastructure behind it usually has not been touched since original construction. The gas branch is half-inch because a 40,000 BTU atmospheric tank never needed more, and the vent is a B-vent chase or masonry flue that no tankless unit can legally reuse.
Heater placement in Plantation Resort skews toward the garage and interior utility closets rather than the attic, which is a real advantage over the newer tract neighborhoods to the north. A garage conversion is generally the least expensive and least disruptive tankless install we do in east Frisco, because the vent run is short, the condensate has an easy path and the unit is trivially accessible for annual descaling. Where a home does have an attic heater, the standard attic package applies: insulated or re-routed condensate, neutralizer, secondary pan with leak sensor and decked service access.
The mature canopy here deserves a mention because it is genuinely operational. Sidewall vent terminations under the drip line of large trees collect leaf litter every autumn, and a partly obstructed termination restricts combustion air and produces intermittent faults that look like a control board problem. Where clearances allow, we place terminations clear of the drip line and re-screen them at the annual service visit.
Why here: The vent that served an atmospheric tank in 1992 is not a valid vent for any tankless unit. Reusing it is a code violation and a carbon monoxide risk.
What we do: We install new venting sized for the unit, PVC or polypropylene for a condensing model or Category III stainless for a non-condensing model, with correct clearances at the termination.
Why here: A 40,000 BTU tank needed nothing larger. A 199,000 BTU tankless unit demands roughly five times the input and will fault under load on an undersized line.
What we do: We run a whole-house gas load calculation and upsize the branch to three-quarter inch, or pull a dedicated line from the meter where the routing allows.
Why here: Plantation Resort has thirty years of tree growth. Leaf litter collecting in a sidewall termination under a drip line restricts combustion air and causes seasonal faults.
What we do: We clear and re-screen the termination and, where clearances permit, relocate it out from under the canopy so the problem does not recur every fall.
Why here: Homes on their third-decade equipment fail by leaking. A garage tank letting go floods the slab and often the adjoining interior wall.
What we do: Converting to a wall-hung tankless unit removes the stored reservoir entirely and frees the garage floor, and the short vent path makes this the most cost-effective conversion location in the neighborhood.
Why here: A check valve or pressure reducing valve at the meter closes the system, so each heating cycle raises pressure with no relief path, stressing fixtures and the new unit.
What we do: We install a properly charged thermal expansion tank and verify static pressure at the same visit.
Services
$2,900 to $5,800 for a complete conversion in Frisco
Swapping the appliance is the easy part. The gas line, the flue the furnace was sharing, and the house pressure are what make a conversion succeed or fail.
$350-$1,800 for most tankless vent installations
Tankless units vent under positive pressure. That single fact rules out every B-vent flue in Frisco and decides which unit can go where.
$450-$2,400 for most tankless gas line upgrades
A tankless unit can demand five times the gas of the tank it replaced. The pipe that fed the tank almost never carries it, and the failure is intermittent rather than obvious.
$2,200-$4,800 installed for most Frisco replacements
Replacing a tankless unit that has reached the end of its life is a different job than a first-time install. We treat it that way.
$189-$349 per unit
Frisco water runs 8-11 grains per gallon. Calcium goes exactly where it does the most damage: the hottest surface in your heat exchanger.

There is a consequence of a tank-to-tankless conversion on housing of this age that almost never appears on a quote, and when it goes wrong it goes wrong in the heating system rather than in the plumbing. It concerns what the old flue was doing before you took the tank off it.
In construction of this period it was routine for a natural-draft storage tank and a natural-draft furnace to share a single vent sized for their combined output. That sizing matters, because a natural-draft vent works on buoyancy alone. A flue oversized for the appliance connected to it does not produce a stronger draft. It produces a weaker one, because the same quantity of exhaust is spread through a larger cross section, cools faster against the flue wall and loses the buoyancy carrying it.
This is precisely what a tankless conversion does if it is treated as a plumbing job in isolation. The tank comes off the shared flue because a tankless unit cannot use it. The furnace stays. The furnace is now orphaned. The correct response is to re-evaluate the vent for the appliance that remains, which usually means relining the chimney with a liner sized for the furnace alone, and it is a real cost that belongs on the quote rather than appearing as a mysterious heating problem the following winter.
The abandoned chase also has to be dealt with rather than simply left. It is not a vent for the new appliance under any circumstances, and an open unused flue penetration is a path for air, water and wildlife. Capping and sealing it is a small item that is genuinely often forgotten.
Where the equipment already sits in a garage, the vent economics are as good as they get in Frisco, and that advantage is real. What is worth knowing before the work is priced is that a garage brings a set of constraints that apply nowhere else in the house, and an installer who treats it as merely a convenient wall will produce something that does not pass.
| Constraint | What it means in practice | Why it exists |
|---|---|---|
| Ignition source elevation | Traditionally 18 in above the garage floor, with exceptions for certain listed appliances under current code | Gasoline vapor is heavier than air and collects at floor level |
| Vehicle impact protection | Bollards or a barrier where the unit sits in the path of a parked car | The appliance and its gas connection are directly strikeable |
| Condensate to an approved receptor | A named destination, not the garage floor and not the driveway | pH 3 discharge attacks concrete and is a slip and ice hazard |
| Freeze exposure | An unconditioned garage can sit near or below freezing on a cold night | Built-in freeze protection is electric and needs uninterrupted power |
| Clearance to combustibles | Per the appliance data plate, to sides, front and above | Wall-hung units are frequently mounted against stored material |
| Dedicated receptacle | A 120V supply the unit does not share with a door opener or a freezer | A tripped shared circuit disables freeze protection silently |
The elevation requirement generates the most argument, and the honest position is that it depends on the appliance listing and on the inspector. The resolution is to read the listing on the unit being installed and to raise the mounting height where there is any doubt, which costs nothing at installation and is expensive to correct after a failed inspection.
Freeze exposure is the constraint that is most often waved away and most often bites. A wall-hung unit in an unheated garage holds only a small volume of water, but a small volume of water is quite sufficient to split a heat exchanger when it freezes. Manufacturers build in electric freeze protection for exactly this case, and it works, provided the unit has power. A multi-day freeze combined with a power interruption removes that protection at precisely the moment it is needed, which is why isolation valves with drain ports on a garage installation are not merely a descaling convenience. They are the means by which a homeowner can drain the unit in twenty minutes when a hard freeze is forecast and the grid looks uncertain.
A sealed-combustion tankless unit has two pipes going outside, and they fail in different ways with different symptoms. Because both present as intermittent lockouts, they get lumped together as a vent problem and treated with a reset. Separating them is straightforward once you know what each one does.
Restrict the exhaust and the unit sees back pressure, the fan cannot move its designed volume, and the safety circuit shuts it down. Restrict the intake and the burner runs progressively richer as it is starved of air, which shows up in combustion readings and flame stability long before it produces a hard fault. Get exhaust into the intake and you have a third condition entirely, where the unit is being fed its own combustion products.
| What the household reports | Most likely cause | First thing to inspect |
|---|---|---|
| Lockouts clustered in one season, clear at other times | Debris accumulating at a termination screen | Both termination screens, physically, at the outside |
| Lockouts only on windy days | Wind loading the termination or driving exhaust into intake | Termination orientation and the separation between the two pipes |
| Gradual loss of output with no code at all | Partial intake restriction running the burner rich | Intake screen and the combustion readings |
| Immediate lockout every time on ignition | Full obstruction, or a disconnected or damaged vent joint | The whole vent run, joint by joint, before anything else |
| Sooting or discoloration at the termination | Incomplete combustion, air supply or vent related | Stop using the appliance and get combustion measured |
In a neighborhood with a thirty-year canopy the seasonal row at the top of that table is the common one, and the fix is unglamorous. Terminations get inspected and cleared at the annual service, screens get checked for corrosion as well as blockage, and where the clearances permit the termination gets located away from where debris naturally lands. None of that requires parts. What it requires is somebody looking at the outside of the building rather than only at the display on the appliance.
A tankless unit is a more sensitive appliance than the tank it replaces, in one respect nobody mentions at the point of sale. A storage tank is a large open vessel that tolerates whatever the supply piping sends it, because debris settles to the bottom and sits there for a decade. A tankless unit passes every drop through narrow passages, past a flow sensor that has to read accurately, and through a fine inlet screen.
On housing in service for three decades, the supply side has accumulated things: solder flux residue, scale shed from pipe walls, fragments of failed washers and seats. None of it troubled the tank. All of it now arrives at a fine mesh screen.
A partly blocked inlet screen matters because its symptom is so misleading. The unit needs a minimum flow to fire and it measures that flow at the inlet, so a restriction there makes the appliance either refuse to fire on small draws or modulate below what the demand requires. The homeowner experiences a new water heater that is worse than the old one. The cause is a screen that rinses out in a few minutes, and it is one of the first things we check before anybody discusses replacing a component. We work from 6960 Parkwood Blvd in Frisco, close enough to this side of town that looking at a screen need not become an afternoon. Call (972) 430-9024.

Yes. Frisco Tankless Water Heater Pros works from 6960 Parkwood Blvd in Frisco 75034 and reaches Plantation Resort off Eldorado Parkway and Hillcrest Road easily within our daily radius. On housing this old, a local crew saves you a second trip. We already expect the half-inch gas branch and the unusable B-vent chase in a 1990s Plantation Resort home, so the quote reflects the real scope instead of a national call center's flat rate that changes once the tech opens the closet. Call (972) 430-9024.
No, and this is worth being blunt about because it is a safety issue rather than a preference. The B-vent or masonry flue that served your atmospheric storage tank was designed for hot, buoyant combustion gases rising on their own. A tankless unit is fan-assisted and its exhaust behaves completely differently. A condensing unit vents in PVC or polypropylene and produces acidic condensate in the vent itself. A non-condensing unit requires Category III stainless. Either way the old chase gets abandoned and new venting gets installed.
In Plantation Resort it is usually the best place, and that is a real advantage this neighborhood has over the newer attic-heavy tract communities north of here. A garage wall gives a short exterior vent run, an easy condensate path to a drain or an approved discharge point, and effortless access for the annual descaling that Frisco's 8 to 11 grain water makes necessary. It also removes any water-bearing appliance from above finished ceilings, which matters in a house with thirty-year-old plumbing elsewhere.
Seasonal faults in this neighborhood are frequently a vent termination problem rather than an appliance problem. Plantation Resort has a mature canopy, and a sidewall termination sitting under a drip line collects leaf litter each fall. A partly obstructed termination restricts combustion air, which shows up as intermittent lockouts that clear when the wind changes and get misdiagnosed as a control board fault. We clear and re-screen the termination and, where clearances allow, relocate it out from under the canopy.
