Most people are sold tankless by someone who does not ask about their gas line. If your supply cannot carry it, the unit will short-cycle and you will have paid four thousand dollars to be colder. We run the numbers before we recommend anything.

Tank replacements run $1,450 to $2,400 fitted. Tankless starts around $4,200.
What the job includes
- Gas line and venting capacity checked before we quote
- Old unit drained, disconnected and hauled away
- New expansion tank and shut-off fitted as standard
- Permit pulled and inspection scheduled
- Temperature set, tested and logged on the work order
What moves the number
- Fuel type
- Electric to gas conversions need a line run and a permit. Budget $800 upward.
- Location
- Attic and crawlspace installs need a pan and drain line. Around $180.
- Code catch-up
- Older installs often lack an expansion tank or drip leg. Both are cheap and both are required.
Asked on this job
Tank or tankless?
If you have gas capacity, a long run to the far bathroom, and you plan to stay ten years, tankless. Otherwise a good tank unit is the better buy and we will tell you so.
How long does a swap take?
Half a day for a like-for-like tank replacement. A day if venting or gas has to change.
