ServicesTankless Water Heaters
Tankless Water Heater Installation in Woodbury
We swap out worn tank heaters for tankless units that heat water as you use it. We size the unit to your home, check the gas line or electrical service, and handle venting and the permit. One person stays your contact from estimate to cleanup.
What a tankless install really involves
A tankless heater only fires when a tap opens. No 50 gallons sitting in a tank, no waiting for it to recover after two showers. The tradeoff is that it has to be sized right. A unit that is too small gives lukewarm water when the dishwasher and a shower run at once.
Most of the work is not hanging the unit on the wall. It is the parts around it. A gas tankless often needs a bigger gas line than the old tank used, and it needs its own vent. An electric one can draw more power than an older panel can spare. We look at all of that before we quote, so the price you hear is the price for the whole job.
Every install is work by a Master Plumber. You get one person who answers your questions, sets the schedule and checks the finished job with you.
What's included in the install
- Sizing to your hot water use
- We count your fixtures and ask how your household uses water at the busiest time of day. Then we pick a unit by flow rate, measured in gallons per minute. Winter matters here, because colder incoming water means the heater has to work harder to reach the same temperature.
- Gas line or electrical check
- Gas units often need a 3/4 inch line or larger to get enough fuel. We measure the run and upsize it if needed. For electric units we check your panel and tell you plainly if it can carry the load.
- Venting and condensate
- We install the vent the manufacturer calls for, usually PVC for condensing units or stainless for others. Condensing units also need a drain for the water they produce, and we route that too.
- Service valves for flushing
- We add isolation valves so the unit can be flushed without cutting into pipe. Hard water leaves scale inside the heat exchanger, and a yearly flush keeps the unit running well.
- Old tank removal and cleanup
- We drain and haul off the old water heater. The work area gets swept and wiped down before we leave.
Signs it's time to look at tankless
Your tank is past 10 years
Most tank heaters wear out somewhere past the ten year mark. Planning the change now beats a cold shower and a wet floor later.
Hot water runs out
If the second or third shower goes cold, the tank can't keep up with your household. A properly sized tankless does not run out.
Rusty water or popping sounds
Brown hot water points to a tank rusting from the inside. Popping or rumbling means sediment has built up on the bottom.
Water around the base
A tank that is seeping at the bottom is near the end. There is no fix for a rusted-through tank. It needs replacing.
You need the floor space back
A tankless unit hangs on the wall. That frees up a closet or a corner of the garage.
How the job goes
- 1
Free estimate at your home
We look at your current heater, the gas or electric service and where the vent can run. You get a written estimate that spells out each part of the job.
- 2
Permit and scheduling
We pull the permit where one is required and set a day that works for you. The same person you met at the estimate is the one you call with questions.
- 3
Install day
Most installs take a day. We shut off water and gas, remove the old tank, mount the new unit and make the gas, water and vent connections. Expect hot water to be off for part of that day.
- 4
Startup and walkthrough
We fire the unit, check for gas and water leaks and set the temperature. Then we show you the flush valves and how the controls work, and leave the area clean.
What moves the price
Two tankless jobs on the same street can cost very different amounts. The unit is only part of it. What it takes to feed and vent that unit in your home is the rest. We price it all up front, and financing options are available. We take all major credit cards and cash.
- Unit size and type
- A larger unit for a big household costs more than one for a couple. Condensing gas units cost more up front but run more efficiently.
- Gas line upsizing
- If the existing line is too small, we run a larger one from the meter or a nearby branch. A long run or a tight crawl space adds time.
- Vent route
- A short run straight out an exterior wall is simple. Going up through an attic or around obstacles takes more pipe and labor.
- Electrical capacity
- Electric units can need several large breakers. If your panel is maxed out, that work has to happen before the heater goes in.
- Location change
- Keeping the heater where the old tank sat is cheapest. Moving it means new water, gas and vent runs.
Tankless water heater questions
Something not covered here? (931) 259-4537
Gas or electric, which is better for my home?
If you already have natural gas or propane, a gas unit usually handles more hot water at once. Electric units are simpler to vent but need a lot of power. We look at what your home has and give you a straight answer at the estimate.
Will I really never run out of hot water?
You won't run out, as long as the unit is sized for how many fixtures run at the same time. If you ask more of it than it was sized for, the water gets cooler. That is why we spend time on sizing.
How long does the install take?
Most swaps are done in one day. Jobs that need a new gas line or a long vent run can take longer. We tell you at the estimate how long your job should take.
Does a tankless heater need maintenance?
Yes. Plan on flushing it about once a year to clear mineral scale, more often with hard water. The service valves we install make that a short job.
What if my old water heater fails before we schedule?
We offer 24/7 emergency plumbing service. If your tank fails and floods, we can come out, shut things down and talk through getting hot water back.
Do you install in towns outside Woodbury?
Yes. We also work in Smithville, McMinnville, Murfreesboro and other nearby towns. Ask when you call and we'll let you know.
