Installation Cost Calculator
Build an itemized estimate covering equipment, gas line, venting, electrical and permit.
Itemized in writing, so you can see what the equipment costs and what your particular house costs. No forms, no callback queue.
Quick Answer
Call Frisco Tankless Water Heater Pros at (972) 430-9024. We ask a few questions by phone, then measure the existing gas branch, vent path and electrical supply on site and give you a written itemized price. The quote is free and there is no form to fill in — installed cost in Frisco typically falls between $2,500 and $6,500.
How it works
Tell us the house, the current setup and what you want out of the change. We can rule things in and out immediately.
Gas branch size and run, total connected load, vent path and clearances, electrical, condensate route. About 30-45 minutes.
Equipment, labor, gas, venting, electrical, permit and disposal listed separately. You keep it whether or not you proceed.
No pressure and no expiring discount. Most whole-house installs are a single day once the scope is agreed.
Before you call
The cost calculator itemizes the same line items we price on site. It will not be exact, but it will be honest about the range.

Yes. Assessing what a tankless installation will take in your home costs you nothing, and you are under no obligation afterwards. What we will not do is give you a firm number over the phone, because the gas branch and vent path have to be measured before anyone can honestly price the job.
Because a form throws away the useful part. The size of your existing gas line, the age of the house, where the current heater sits and how many fixtures run at once all change the price, and those come out in two minutes of conversation. A form just puts you in a callback queue.
Equipment, standard labor, gas line work if the existing branch is undersized, venting and termination, condensate handling on condensing units, electrical, permit and inspection, and old tank removal. Each is a separate line so you can see exactly what the installation conditions are costing you versus the unit itself.
Most whole-house gas installations in Frisco land between $2,500 and $6,500 installed. The spread is almost entirely gas line and venting. A home with an adequate 3/4 inch branch and a short sidewall vent run sits at the bottom; a two-story with a long vent path through finished space and a required gas upsize sits at the top.
Usually 30 to 45 minutes. We measure the gas branch size and run length, total the connected BTU load of the house, check the vent path and termination clearances, look at electrical availability and work out where condensate can legally drain.
Yes, and those are usually simpler and cheaper because the gas line, venting and condensate route already exist and were sized for a tankless unit. The main things we verify are whether the old unit's vent material matches what the new one requires and whether the failure was caused by scale, which changes what we recommend.
What we quote
$2,500–$5,500 installed for most Frisco homes
Properly sized, permitted and vented on-demand hot water for Frisco homes — from Starwood estates to Frisco Lakes patio homes.
$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.
$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.
$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.
$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.
$2,600 to $5,500 installed, before any meter or service upgrade
The BTU rating on the box is meaningless if the pipe feeding it cannot deliver the gas. We size the fuel first.
