Endless hot water, lower energy bills, and a unit built to last 20+ years. Eco-Flow handles gas line assessment, sizing, venting, permits, and full installation — one call, one crew.
Conventional tank heaters keep 40–50 gallons hot around the clock, whether you use it or not. Tankless heats on demand — saving energy, lasting longer, and performing better in a coastal environment where steel tanks corrode faster than they should.
A tankless installation involves more than swapping the old unit. We handle every step — so the system is correctly sized, safely connected, and properly permitted from day one.
Most installations are complete in one day. Here's what to expect from the moment you call to the inspector signing off.
The permit process adds a few days to the overall timeline, but doesn't mean you're without hot water during that time — we install first, then schedule the city inspection.
We assess gas line size, venting route, electrical, and installation location before quoting — so there are no surprises once work begins.
Cost varies based on whether gas line work is needed, the venting route, and the unit itself. These are realistic ranges for common scenarios — not quotes, but an honest baseline.
| Scenario | Typical Range |
|---|---|
| Straightforward swap — adequate gas line, simple wall venting, outlet available | $2,100–$3,000 |
| Standard conversion — gas line upgrade, new venting, condensing unit | $3,500–$4,500 |
| Complex installation — significant gas line work, new electrical circuit | $4,500–$6,000+ |
| Gas line upgrade only (branch from meter to unit) | $400–$900 add'l |
| New dedicated electrical circuit | $200–$400 add'l |
These are ranges, not quotes. Actual cost depends on site conditions assessed during the initial visit. Permit ($80–$150) and old unit disposal are included in all estimates. For a full breakdown see our tankless installation cost guide →
