Our Process

1

Unit Selection & Quote

We recommend the right unit size and type for the property based on square footage, number of bathrooms, and investor goals (flip vs. rental). Quote provided same day.

2

Permit Pull

All water heater replacements in Davidson County require a permit. We handle this automatically — no surprises from the inspector.

3

Removal & Install

Old unit is safely disconnected, drained, and removed. New unit is installed with proper connections, TPR valve, drain pan, and required expansion tank.

4

Gas/Venting Upgrade (if needed)

Tankless conversions often require gas line upsizing and new direct-vent runs. We handle all of this in one visit when possible.

5

Test & Documentation

System is fired up, tested for proper temperature and pressure, and documented with serial numbers and permit records for your file.

Water Heater Installation & Tankless Upgrades — Frequently Asked Questions

Is a tankless water heater worth the investment for Nashville rental and flip properties?
For rentals held 3+ years, yes — the math is clear. Nashville's average gas rates and a typical tankless unit saving 20–30% on water heating costs yields a payback period of 4–7 years, plus reduced maintenance calls (no tank to fail unexpectedly). For short-term flips, the ROI case is different: tankless units are a listing upgrade that resonates with buyers in the $400K+ market, particularly in newer neighborhoods like Germantown, The Gulch, and 12 South where buyers expect modern systems. We'll give you the honest trade-off based on your exit strategy.
What gas line and venting changes are required for a tankless conversion in Nashville?
Most Nashville homes originally plumbed for 40- or 50-gallon tank heaters have 1/2" or 3/4" gas lines, which are undersized for tankless units. A whole-house tankless typically needs a 3/4" or 1" gas line from the meter, plus a direct-vent pipe to exterior (most tankless units can't use the existing B-vent flue). We assess the existing gas infrastructure during our initial walk-through and include all necessary upgrades in the quote so there are no day-of surprises on your flip budget.
How quickly can you install a water heater on an active flip site?
Standard tank replacements (like-for-like, same location) are typically completed in 2–4 hours once the permit is active. We can usually schedule within 24–48 hours for flip clients. Tankless conversions requiring gas line and venting work take a full day. For properties with no existing water heater (new rough-in), we coordinate with your GC's rough-in schedule to avoid double-mobilization costs.
What size water heater should I install in a Nashville flip or rental?
For a 3-bedroom flip targeting the mid-market Nashville buyer, a 50-gallon natural gas or 40-gallon heat-pump electric unit is standard. For Airbnb or short-term rental properties with high turnover, we recommend either a 50-gallon gas or point-of-use tankless supplemented by a whole-house unit. Belle Meade and Green Hills buyers expect tankless in luxury renovations. The biggest mistake we see: flippers installing undersized 30-gallon units to save $150, then having buyers flag it during inspection. Right-size from the start.
